Kraft paper packaging products are very common in our lives, such as melon seed bags, three Squirrel nut bags, coffee bags, hand cake bags, file bags, dog food bags, popcorn bags.
In the past two years, with the global prevalence of 'anti-plastic' style, products packaged with kraft paper materials have become more and more popular with consumers, and Kraft paper bags have become the first choice for more and more enterprises to package their products.
Even big brands such as McDonald's, Nike, Adidas, Samsung, Huawei and Xiaomi have begun to replace plastic shopping bags with high-quality kraft paper bags.
Investigate its reason, what is the reason why Kraft paper bags are so popular with consumers and dealers?
We know that Kraft paper usually has three colors, one is yellowish brown and yellowish brown, the second is semi-bleached kraft paper with light brown, and the third is fully bleached kraft paper with cream or white.
First, the advantages of kraft paper bags: 1, the environmental performance of kraft paper bags.
Today, more and more attention is paid to environmental protection. Kraft paper is non-toxic and tasteless. The difference is that Kraft paper is pollution-free and can be recycled. 2. Printing performance of kraft paper bags.
The special color of kraft paper is itself a feature.
Moreover, the Kraft paper bag does not need full printing, and only simple lines can outline the beauty of the product pattern. The packaging effect is better than the plastic bag.
At the same time, the printing cost of kraft paper bags is greatly reduced, and the production cost and production cycle of its packaging are also reduced. 3, the processing performance of kraft paper bags.
Compared with the shrink film, The Kraft paper has a certain cushioning performance, anti-fall performance, better stiffness, and the mechanical parts of the product processing have good cushioning properties and are convenient for composite processing.
Second, the shortcomings of kraft paper bags: the main disadvantage of kraft paper bags is that they can not encounter water. The Kraft paper that encounters water softens, and the entire Kraft paper bag is softened by water, the place where the bag is stored should be kept ventilated and dry, and the plastic bag has this problem.
Another small drawback is that if the kraft paper bag is to print a colorful and delicate pattern, it will not achieve that effect.
Because the surface of kraft paper is relatively rough, there will be uneven ink when printing to the surface of kraft paper.
Therefore, compared with plastic packaging bags, the printed patterns of plastic packaging bags are relatively delicate.
Zhongbao color plastic thinks that if the items packed in the packaging bag are liquid, the packaging material should not be made of kraft paper as far as possible. Of course, if the kraft paper material must be used, the composite film made of kraft paper should also be used, avoid Kraft paper from contact with liquid. Shijiazhuang packaging products 12
