In 2010, with the initial recovery of the global economy, China's tissue paper market demand is strong and continues to maintain rapid growth momentum. According to the "2010 Overview and Outlook of the tissue paper industry" prepared by the China Paper Association's tissue paper committee, In 2010, there were about 1,400 registered manufacturers of the China Paper Association's tissue paper committee, including about 500 comprehensive companies in the production of raw paper.
In 2010, the consumption of household paper increased by 11.1% year-on-year, and the market size (total market sales) reached approximately 54.32 billion yuan, an increase of 19.7% over 2009. The per capita annual consumption increased from 3.14 kg in 2009 to 3.48 kg. Compared with Japan and Western Europe (15 kg) and Hong Kong, Macao and Taiwan (10 kg), there is still a considerable gap. The long-term growth potential of the tissue paper market is still very large. So for the companies that provide packaging for tissue paper, the development prospects are still very impressive.
According to a 2010 survey by the China Paper Association's Tissue Paper Committee, domestic paper products are dominated by tissue paper, accounting for about 66.5% of the market share, and other categories are facial tissue paper 18.2%), handkerchief paper (7.2%) , Napkins (2.6%), paper towels (1.8%), kitchen paper (1.4%), stabilizer (1.4%), etc.
First, the issues that should be paid attention to
The marketing strategies of major tissue manufacturers in 2010 (such as Hengan, Jinhongye, Vinda, Zhongshun, Shanghai Dongguan, etc.) are mainly manifested in two aspects: one is to seek high profits by launching differentiated products Market, the second is to promote the concept of green and environmental protection. This requirement has brought double pressure on packaging cost and quality to packaging companies.
Prior to this, most of the packaging used for household paper used polyamide inks. This type of ink was an ink variety developed in the 1950s and 1960s. It has good gloss and good adhesion to various films when used for surface printing. , Moderate price characteristics, printing and packaging of various paper towels have been using this type of ink (except composite packaging). However, with the introduction of GB9685-2008 and GB / T10004-2008, the application of this type of ink on paper towel packaging has gradually decreased.
1. Ink-free benzene. Because this type of ink uses toluene as the main solvent, although there is no clear standard for this type of product for the time being, no matter whether it is a paper factory or a printing factory, the residual solvent standard for composite packaging is on par. The consensus in this regard is very obvious, and the ink should also be dephenylized, but sooner or later.
2. Odor of ink Due to frequent food safety accidents, people have higher safety requirements for items and food in contact with life. The handkerchief paper used for interior packaging is more demanding in terms of odor. Some time ago, a printing factory I contacted had a dispute with a paper mill because of odor problems. Later, this company approached us to help analyze: Excluding the odor of the film itself, and the reason for the impurities in the dilution water, we found that it was the taste of the resin used in the ink. Generally speaking, the release of the solvent from the polyamide resin is still good under a reasonable formula. The key is that the polyamide resin itself also has a special taste. The acceptance of the odor is originally a subjective indicator. It mainly depends on the human nose. Some people are not sensitive to the odor, and some are very sensitive to the odor. If they are sensitive, it will increase the divergence and risk of acceptance. So, if possible, no one wants to have this kind of risk.
3. The friction coefficient of film and ink everyone is working on how to reduce costs, so in addition to using traditional PECPP film packaging, SPP (double-sided smooth OPP heat-sealing film) is also featured with its price advantage and good performance. A soft packaging stage for tissue paper. For packaging machines that are packing faster and faster, the coefficient of friction between film and ink is a key indicator.
It is advisable to control the friction coefficient of the ink from 0.2 to 0.35. Too small or too large will affect the smoothness of the machine. This is one of the reasons printing affects the efficiency of automatic packaging.
4. Film curling The reasons that affect the efficiency of automatic packaging also need to consider film curling after printing, especially large-format printing. The shrinkage stress of the ink during film drying must be considered. Shrinkage stress causes the film to curl, so experienced printers have fully evaluated this item.
Tissue packaging has considerable development prospects, and the correct selection of printing inks is very important to ensure the quality of the packaging. When choosing flexible inks, flexible packaging enterprises should not only focus on the price, but also focus on the quality and characteristics of the ink.
