早上开机测试了胶水比例,涂胶量,都没问题, A/B 100/80 , 涂胶 1.6 克。 Solvent-free problem: Start up in the morning and test the glue ratio and the amount of glue, no problem, A / B 100/80, 1.6 grams of glue . OPP/CPP , 10 卷膜。 Material OPP / CPP, a total of 10 rolls of film. Production has begun. Volumes 1 to 6 are fine, volumes 7 and 8 are self-adhesive, and volumes 9 and 10 are fine. The self-adhesive part will be much better if it is dried again, but it is difficult to dry the inner layer of the film close to the paper tube. Please advise!

两会代表提议出台禁止使用塑铝复合膜,而在现阶段,塑铝复合膜是我们软包装最常用的高阻隔材料之一。 1. The representatives of the two conferences proposed a ban on the use of plastic aluminum composite film, and at this stage, plastic aluminum composite film is one of the most commonly used high barrier materials for our flexible packaging. Do you think the representative's proposal is feasible from the perspective of packaging technology ?

(521154028) Boli Packaging Li Qiuhe (521154028)

Let me talk about my views

Aluminized film has a very high share in packaging. As for food packaging , aluminized film also accounts for a large proportion. In the eyes of ordinary consumers, the aluminized film still feels a relatively high-grade packaging (actually, the barrier property of the aluminized film is good at the beginning), but the aluminized film used now basically only plays a decorative role and has a beautiful appearance Therefore, the current use of aluminized film in food packaging is very limited for food packaging safety.

Regarding the standard for banning the use of aluminized film, I think it should be classified. If it is used for decoration and appearance, it can be used aluminized film. If its high barrier performance is to be used, it is prohibited to use aluminized film.

(276731763) Xiamen Changsu Wang Xiaofei (276731763)

[ 表情 ] 对于需要遮光要求的 也需要铝箔 除了铝箔不知道别的方式能达到要求? I ’m here to learn [ Expression ] For those who need shading, they also need aluminum foil. In addition to aluminum foil, I do n’t know if other ways can meet the requirements?

Mr. Tong Zezuo:

Aluminized film is an alternative to aluminum-plastic composite.

15% ,铝塑复合膜的确不好回收再用。 The representative's proposal is feasible. Now pure aluminum foil itself is used less, the proportion does not exceed 15% , and the aluminum-plastic composite film is indeed difficult to recycle.

Kevin (735003894) Blaine Functional Film , Kevin Mat (735003894)

The definition of plastic aluminum composite film in Chinese national standards and global definition refers to composite materials containing aluminum foil and plastic. Its main disadvantage is the problem of recycling and degradation of the material after use, but it still has advantages for the barrier protection of the product. . Therefore, aluminum and plastic composite materials are relatively rare in European and American countries. Aluminized film and high barrier co-extrusion film are substitutes for aluminum-plastic composite.

- 卞南杰: American Packaging Machinery Association - Tong Nanjie:

The aluminum-plastic composite solves two problems of oxygen barrier and light shielding, and brings the problem of difficult degradation. If even the barrier properties are not reached, the responsibility for pollution will increase.

(276731763) Xiamen Changsu Wang Xiaofei (276731763)

那我的问题改下 除了铝箔或者镀铝 通过印刷黑色油墨或者涂黑色胶水类的能否达到遮光要求? Um, then my question is changed . Can the light shielding requirements be met by printing black ink or coating black glue except aluminum foil or aluminum plating ?

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

For aluminized film and high-barrier co-extruded transparent film, it can indeed replace aluminum-plastic composites in large applications, although not in all areas.

On products with extremely high barrier requirements, the current barrier of aluminized films is closest to or even exceeds that of aluminum-plastic composite films. On products with medium barrier requirements, high barrier co-extruded transparent films have advantages.

Qi Bo:

The main function of packaging aluminum plastic film is to protect from light. Pet 复合 Al Pet barrier is no problem at all, why use Pet composite Al ? Al 的价格是 vmpet 2 倍多,而且质量,工艺要求也高,能用 vmpet 的谁会傻增加成本和风险? Avoiding light is the main consideration. The price of Al is more than twice that of vmpet , and the quality and process requirements are high. Who can use vmpet to increase the cost and risk?

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

How to replace the aluminum-plastic composite material still needs to be determined according to the specific requirements of the product. WVTR,OTR 要求非常高,但又不需要高温蒸煮的条件下,无论是 VMPET VMBOPP 都有代替的方案。 For WVTR, OTR requires very high conditions, but does not require high temperature cooking conditions. Whether it is VMPET or VMBOPP, there are alternatives.

At present, the technology of aluminum coating has been developed to reach the same level as aluminum foil for water and oxygen blocking.

If it is just to avoid light, there are more solutions, and there is no need to use aluminum-plastic composite materials.

(1164078543) 2016-04-07 14:43:08 WeChat pays attention to the leading edge of packaging (1164078543)

- 卞南杰 : American Packaging Machinery Association - Tong Nanjie :

Co-extruded films should also have degradation problems.

Or maybe can burn

(372529132) The Frontier of Packaging Shen (372529132)

2 个问题的讨论吧! OK, let's enter the discussion of the second question! Now that we want to replace it, we first understand the advantages and limitations of the aluminum-plastic composite film (pinhole, solvent-free composite difficulties)

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

Of course, one advantage of aluminum foil is that there is currently no possibility of replacement. For its folding performance, some packaging requires this folding performance, such as aluminum foil for chocolate packaging.

: President Hua Xin Wu :

In addition to the light blocking property, the aluminum foil metal material has good packaging appearance characteristics.

- 卞南杰 : American Packaging Machinery Association - Tong Nanjie :

Appearance and consumer quality are related

- 卞南杰 : American Packaging Machinery Association - Tong Nanjie :

The price of small bottles of drinks in Australia is high, in order to reduce plastic waste, but also the support and understanding of the whole society

(372529132) The Frontier of Packaging Shen (372529132)

It seems that if there is aluminum foil in the milk powder packaging, the metal detector cannot be used to detect whether there are metal debris in the milk powder.

Therefore, there is a trend now to replace pure aluminum foil with transparent high barrier film

(521154028) Boli Packaging Li Qiuhe (521154028)

However, the barrier properties of aluminized films currently used are not high.

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

In fact, the market choice of materials comes from costs on the one hand, and from the guidance of national regulations on the other.

(372529132) The Frontier of Packaging Shen (372529132)

In this way, milk powder food packaging can be detected with a metal detector, which can be more secure.

(521154028) Boli Packaging Li Qiuhe (521154028)

The current quality of the aluminum coatings used in food packaging materials in China is generally poor. The peeling force of the layer is low. The barrier properties of the aluminized film are also not satisfactory. Speaking of advantages, the price of aluminum coating is now low (this is the key), and the color of the ink after lamination is better against the aluminum layer, and the appearance is beautiful.

: President Hua Xin Wu :

At present, high-barrier materials can be processed by deep-processing co-extrusion coating, and some products cannot be packaged with high-speed aluminum foil.

- 卞南杰 : American Packaging Machinery Association - Tong Nanjie :

Can you provide a composite food bag that can be frozen at -80 degrees Celsius and can be heated by microwave?

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

Freezing at minus 80 degrees? This condition is really high, usually minus 18 degrees

不错,目前镀铝膜由于价格竞争,阻隔性能很差,附着力也很差,反而限制应用 @ 博 力 包装 李秋 禾 is good. At present, due to price competition, the aluminized film has poor barrier properties and poor adhesion, which limits its application.

: President Hua Xin Wu :

Tetra Pak ? Shelf life !

(521154028) Boli Packaging Li Qiuhe (521154028)

But the price is cheap, so there is still a market

Of course, high barrier transparent film has good performance and high price.

- 卞南杰 : American Packaging Machinery Association - Tong Nanjie :

There are low prices and no standards of control, it must be bad coins that expel good coins

Borouge Minjing:

The properties of aluminized composite film and nylon composite film are similar, but they cannot replace each other.

BOPP18/MCPP25 Aluminized composite structure: BOPP18 / MCPP25

BOPA15/CPP25 Nylon composite structure: BOPA15 / CPP25

40 微米 Total thickness is 40 microns

There are two major difficulties in composite aluminized structures: it is easy to drop aluminum, and the composite fastness is not high, but the solvent-free technology is currently mature, so the composite problem is not too big.

The aluminized structure has water and light blocking properties, which cannot be replaced by nylon composites.

25000 / 吨、镀铝 CPP 10600 、复合 CPP9600 / 吨。 Cost gap: Nylon film 25,000 yuan / ton, aluminized CPP film 10600 , composite CPP 9600 yuan / ton.

: 膨化,油炸食品、薯片、方便面、饼干。 Aluminized composite packaging objects : puffed, fried food, potato chips, instant noodles, biscuits. Nylon composite packaging can only contain biscuits.

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

- 卞南杰 : 在没有国家法规的引导下,只能是劣币驱逐良币,所以国家立法层面是需要去引导,制定标准。 I strongly agree with the American Packaging Machinery Association - Tong Nanjie : Without the guidance of national regulations, bad coins can only be used to expel good coins, so the national legislative level needs to guide and develop standards. However, the country is already working on environmental protection and degradation.

VOCs charging is also a direction guide.

(372529132) The Frontier of Packaging Shen (372529132)

Yes, so after the representatives of the two conferences proposed, there should be some promotion to the development of the industry in environmental protection.

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

And in some industries, the application of degradable materials is also being promoted, and our company is also participating in it. The cost of degradable materials is much higher. Without the guidance of national standards and regulations, it is impossible to be completely driven by the market.

President Hua Xin Wu:

VMPAPER 替代鋁箔襯紙一樣~,值得繼續探討! For example, the cigarette liner lining paper has not yet been completely solved and is completely the same as VMPAPER instead of aluminum foil lining paper. It is worth continuing to discuss!

Kevin 席: Blaine Functional Film, Kevin Seat :

VMPAPER 在用,请教一下,全面使用的难度是哪方面,技术问题没有突破吗 @Wingkeungng should now also have a VMPAPER in use, please ask, what is the difficulty of comprehensive use, technical problems have not been broken?

(372529132) The Frontier of Packaging Shen (372529132)

Mr. Wu, do you use paper coating to get the barrier? I think a lot of aseptic packaging is like this. Can you say that the aluminum coating on paper can be replaced by paper coating?

President Hua Xin Wu:

This product is very simple, and the structure cannot be separated from aluminum foil!

(372529132) The Frontier of Packaging Shen (372529132)

3 个问题吧: Let's move on to the third question:

Advantages and current status of multilayer co-extruded high transparency and high barrier film

Kevin 席: Blaine Functional Film, Kevin Seat :

@Wingkeungng stick gum packaging. Does this need the folding performance of aluminum foil?

President Hua Xin Wu:

7 層材料,包括鋁箔 7 layers of aseptic package structure , including aluminum foil

Kevin 席: Blaine Functional Film, Kevin Seat :

Tetra Pak's currently mature structure contains aluminum foil. However, they are also developing non-aluminum foil products.

Kevin 席: Blaine Functional Film, Kevin Seat :

VMPAPER 搞定。 @Wingkeungng chewing gum folding strip packaging, currently available with VMPAPER . The barrier properties can also meet the needs of such products through structural optimization

(276731763) Xiamen Changsu Wang Xiaofei (276731763)

请前辈赐教 刚才提到镀铝和共挤膜 取代铝箔还有个难点 除了部分产品是遮光需求外 铝箔可耐高温蒸煮 Talking about my personal understanding, please enlighten me . I mentioned that there is still a difficulty in replacing aluminum foil with aluminized and co-extruded films. In addition to some products that require light shielding, aluminum foil can withstand high temperature cooking.

(521154028) Boli Packaging Li Qiuhe (521154028)

,其优点为高透明(消费者可以清楚看到包装的内容物),高阻隔(延长食品的货架寿命,减少食品应为过期而浪费)。 High transparency and high barrier film is an ideal material for current and future food packaging . Its advantages are high transparency (consumers can clearly see the contents of the package), and high barrier (prolong the shelf life of food and reduce food waste due to expiration). . PVDC 高阻隔涂布膜及 PVDC,EVOH 等共挤膜。 At present, the most widely used in China is PVDC high barrier coating film and PVDC, EVOH and other co-extruded films. A small amount of imported high-barrier films are also in use, such as transparent vapor-deposited films (the price is too expensive).

President Hua Xin Wu:

Kevin_ 我們向客戶提供過鍍鋁紙,包裝性差被否決! @ 博莱恩 Functional film, Kevin_ Xi We provide customers with aluminized paper, poor packaging performance was rejected!

-Kevin 席: 哪方面的性能? Blaine- Kevin : Which aspect of performance?

(276731763) Xiamen Changsu Wang Xiaofei (276731763)

尤其是高透明高阻隔且又耐高温蒸煮的材料 除了透明蒸镀材料(李总也说到太贵了)和进口 M 尼龙(阻氧在 8 左右),国内能耐高温蒸煮的透明高阻隔材料还太少 Um, especially high-transparent, high-barrier, and high-temperature-resistant cooking materials. In addition to transparent evaporation materials (which Lee said are too expensive) and imported M nylon (oxygen blocking is around 8 ), domestic high-temperature-resistant transparent high-temperature cooking materials Too little

Gao Dezhen:

In addition to high barrier packaging materials must have good oxygen (such as fatty food), moisture (such as dry food) or odor barrier properties (such as aromatic food), but also have good chemical stability, suitable for food high temperature disinfection and Features such as low temperature storage.

EVOH 树脂共挤薄膜、涂覆 PVDC 薄膜、涂布 PVA 薄膜等。 In order to expand the flexible packaging application field and meet the diversified needs of product packaging, people have developed transparent film materials with barrier properties such as EVOH resin-co-extruded films, coated PVDC films, coated PVA films, etc. PVDC 涂布膜的环保性、 EVOH 共挤膜的环境适应性等等,在一定程度上影响到它们的使用范围。 These films have their own advantages, but there are also some shortcomings, such as the environmental protection of PVDC coating films, the environmental adaptability of EVOH co-extruded films, etc., which affect their scope of use to some extent.

President Hua Xin Wu:

Tetra Pak's currently mature structure contains aluminum foil. However, they are also developing non-aluminum foil products.

This becomes Kangmei Bao.

Gao Dezhen:

In the 1990s, some developed countries, such as Europe and the United States, and Japan in Asia, began research and development on non-metallic (oxide) coatings such as aluminum oxide or silicon oxide coatings. Alumina or silica-coated transparent barrier film not only has the same barrier properties as aluminized film, but also can transmit visible light. It has high microwave penetration. It can be directly used for microwave oven heating and metal detection. Adaptability to atmospheric environment And environmentally friendly. Can be widely used in food, beverages, meat products, condiments, dairy products, electronic parts, precision instrument accessories, microwave products, medicine and other packaging.

EHA 分俩牌号 普通牌号阻氧 2 以下 高温牌号 8 以下 23 50%RH At present, our EHA has two grades, ordinary grades, below oxygen barrier 2 and high temperature grades below 8 ( 23 50% RH ).

Gao Dezhen:

At present, almost all of the transparent barrier films used in China's packaging industry for processing green environmentally-friendly transparent barrier packaging rely on imports from Japan, so packaging products or other products using green environmentally-friendly transparent barrier films are rarely seen in the domestic market.

AmLite packaging uses a high barrier coating from Amco Soft Bag, which is coated with a very thin layer of transparent barrier material on the substrate. Therefore, the high barrier strength of this package is comparable to that of aluminum.

40% 的碳足迹以及 21% 的重量负担。 AmLite packaging can reduce the carbon footprint by 40% and the weight burden by 21% .

After the product is filled and sealed, the package can also be detected by a metal detector to ensure a high degree of product safety.

目前制约蒸镀类薄膜的应用主要是价格太高 还有部分产品容易龟裂等问题 Well, the current restrictions on the application of vapor-deposited films are mainly due to the high price and easy cracking of some products.

EB 塗布項目,能否應用薄膜包材值得研究 There are EB coating projects in China, and whether it is possible to apply film packaging materials is worth studying

(276731763) Xiamen Changsu Wang Xiaofei (276731763)

国内主要用 EVOH 共挤膜、 PVDC 共挤膜、 PVDC 涂布膜等。 At present, transparent areas that do not require high-temperature cooking mainly use EVOH co-extruded films, PVDC co-extruded films, PVDC coating films, etc. in China. Co-extruded film barrier properties are ok, but due to the thickness and thickness, the cost is still relatively high. The oxygen barrier properties of PVDC coated films have not reached the level of coextruded films. But the cost is low.

2 以下,成本与 PVDC 共挤膜类似。 EHA common brands are below 2 oxygen permeate , and the cost is similar to PVDC co-extruded film.

Thank you for your selfless sharing. It seems that the advantages of high barrier transparent films are indeed many, but why haven't they been widely used yet?

4 个问题: Let's enter the fourth question:

4. The problems that need to be overcome by using transparent barrier films instead of plastic aluminum composite films, and the significance of solvent-free composite

(521154028) Boli Packaging Li Qiuhe (521154028)

Solvent-free compounding is a milestone for color printing composite packaging. At present, global food safety is increasingly valued. Limits and prohibitions of various additives, how to better package food and ensure the safety of food during the shelf life, are all This is what we are currently doing. The application of transparent high barrier film solves the problem of food packaging safety, and is also suitable for solvent-free composite processes.

(372529132) The Frontier of Packaging Shen (372529132)

Do you think there are still problems to be solved to replace aluminum foil?

(276731763) Xiamen Changsu Wang Xiaofei (276731763)

1. 蒸镀类阻隔性能好,但以往都需进口,价格太高是主要因素,部分产品不耐揉搓易龟裂等。 The problems to be overcome just mentioned: 1. The barrier properties of vapor deposition are good, but they have to be imported in the past. The high price is the main factor. Some products are not resistant to rubbing and are easy to crack. M 尼龙也需要进口,且价格昂贵, 8~9 万一吨 3. 很多共挤类、 PVDC 涂布类 不耐高温蒸煮,要么阻隔性还不够好。 2. There are too few transparent materials that can withstand high temperature cooking. M nylon also needs to be imported, and it is expensive, 8 ~ 910,000 tons . 3. Many coextrusion and PVDC coatings are not resistant to high temperature cooking, or the barrier properties are not enough. it is good.

(372529132) The Frontier of Packaging Shen (372529132)

The difficulty of solvent-free compounding now lies in the compounding of aluminum foil and aluminizing compound, as well as high-temperature cooking packaging.

If there can be better materials to replace aluminum foil, I believe it will have a more positive meaning for the use of solvent-free

PVDC EVOH 阻隔性不好? @ 厦门 长 塑 王晓飞 PVDC , EVOH barrier is not good?

(372529132) The Frontier of Packaging Shen (372529132)

In our magazine, we have done a lot of research on film issues. Many film companies are developing high-barrier films with barrier properties equivalent to aluminum foil.

(276731763) Xiamen Changsu Wang Xiaofei (276731763)

- 不是的。 @ 众 新 包装 - 不 的. . . PVDC 涂布的 I mean PVDC coated

(372529132) The Frontier of Packaging Shen (372529132)

5. Which high-barrier material do you think is the ideal material to use? Has it entered the practical application stage?

(521154028) Boli Packaging Li Qiuhe (521154028)

The key is to have a cost-effective barrier material

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

In fact, there is no ideal high-barrier material, and each material has specific application conditions and scope. Our aluminized film can completely replace aluminum foil in terms of barrier, but there are also unsuitable application conditions, such as high temperature cooking.

(521154028) Boli Packaging Li Qiuhe (521154028)

Just say yes, the price is high, how many people can accept

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

However, for the requirements of high barrier, and the packaging of medium and light products, it has obvious advantages in terms of material thickness and comprehensive cost.

(521154028) Boli Packaging Li Qiuhe (521154028)

PVDC 涂布膜 I think that the PVDC coating film is the first choice for high barrier materials suitable for China's national conditions.

PVDC 涂布膜是高透明,高阻隔材料 1. PVDC coating film is highly transparent and highly barrier material

是目前性价比最高的高阻隔材料, 2 , is currently the most cost-effective high barrier material,

PVDC 涂布膜不随环境温度、湿度变化而改变性能, 3 , PVDC coating film does not change performance with changes in ambient temperature and humidity,

已广泛应用于食品包装,性能优越。 4 , has been widely used in food packaging, superior performance.

(276731763) Xiamen Changsu Wang Xiaofei (276731763)

也希望客户在对比材料的时候 像席总说的综合考虑 有的薄膜虽然单价高,但是单位面积(也就是单个袋子)的成本更低 Well, I also hope that when customers compare materials, like Xi said comprehensively, some films have a high unit price, but the cost per unit area (that is, a single bag) is lower.

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

Transparent materials also have different choices according to different application conditions. The good and bad materials need to be determined by using conditions and comprehensive cost requirements. But the basic direction is environmental protection, light weight, high barrier

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)

王总说得很正确,我再补充,还需要结合终端使用客户的使用成本。 @ 厦门 长 塑 王晓飞 Wang was right, I added that it also needs to be combined with the cost of using the terminal. Reduce loss, increase automatic packaging speed, etc.

PE 镀铝膜,传统三层结构可以变成了创新两层结构。 With PE aluminized film, the traditional three-layer structure can be transformed into an innovative two-layer structure. PE 镀铝膜达到了降低成本、节能环保、降低 VOCs 排放的目的。 Because the number of composite layers is reduced and the composite structure is simplified, the PE aluminized film has achieved the goals of reducing costs, saving energy and protecting the environment, and reducing VOCs emissions. PE 镀铝膜的优势是不言而喻的。 In the context of today's increasingly stringent energy conservation and emission reduction policies, the advantages of PE aluminum coatings are self-evident.

Kevin (735003894) Blaine Functional Film, Kevin Mat (735003894)
