Wenzhou Junchuan Machinery Equipment Co., Ltd.
Guangxi Fengcai Printing Industry Sange: For dry powder used for packaging soybean products, the water vapor transmission rate of the packaging bag must be controlled to be less than or equal to 0.05g / (m2.24 hours). Which material combination is suitable?
A soft bag: aluminum foil.
San Ying Jiang: Use thick aluminum.
Yingcai Packaging-Han: Printing materials containing K coating or aluminum plating or pure aluminum in the structure can be used. The key is to see what you plan to pack and what structure you need.
Guangxi Fengcai Printing Industry Sange: I use a BOPP // VMPET // IPE structure packaging bag, the best result is 0.1g / (m2.24 hours), if the BOPP // IPE structure reaches 3.6g / ( M.24 hours). The water vapor transmission rate is less than or equal to 0.05g / (m2.24 hours), which is required by customers.
Yingcai Packaging-Han: What is the warranty period for the customer? The moisture and oxygen permeability is linked to the shelf life. If the required shelf life is not long, there is no need to set such a high moisture and oxygen permeability requirement.
Enmei Ink-Wang: There are aluminum foil structure and high barrier structure for controlling water vapor transmission rate, depending on your product requirements and cost requirements.
Guangxi Fengcai Printing Industry Sange: Shelf life is 12 months.
Yingcai Packaging-Han: If customers can afford the money, they will make pure aluminum packaging bags, imitating the structure of milk powder packaging bags like breakfast milk.
Guangxi Fengcai Printing Industry Sange: Thank you.
