Paper packaging materials can be divided into five types: ordinary packaging paper, special packaging paper, trademark packaging paper, oil-proof packaging paper, and moisture-proof packaging paper. Ordinary wrapping paper has strong paper and can be used for general packaging, such as kraft paper, chicken skin paper, etc.; special wrapping paper is named according to its use, and its properties are also different, such as fruit wrapping paper, which is thin and soft; photosensitive protective paper is black and not soft. Translucent; trademark wrapping paper is printed and used for packaging, such as candy wrapping paper; oil-proof wrapping paper has the ability to prevent oil penetration, such as vegetable parchment paper, butter paper; moisture-proof wrapping paper is moisture-proof, such as tar paper, aluminum foil paper wait. According to rough statistics, there are about dozens of types of packaging paper.
The four pillars of modern packaging materials - paper, plastic, metal, and glass. Among them, paper products are growing the fastest. Paper and plastic are the cheapest. Their raw materials come from a wide range of sources. They are not as fragile as glass or as heavy as metal and are easy to carry. Therefore, paper and plastic packaging are widely used in daily life. International health organizations and environmental experts believe that plastic waste may cause white pollution and is not conducive to environmental protection. The use of plastic food bags should be gradually banned and environmentally friendly paper bags must be used for packaging. Therefore, consumers should use non-toxic and harmless "all paper environmentally friendly bags" for shopping in the future.
Paper packaging materials are not only rich in resources and easy to recycle, but also easy to degrade. After paper products decay, they can be recycled or used as plant fertilizers, while also reducing air pollution and purifying the environment. Compared with the other three major categories of packaging materials such as plastic, metal, and glass, paper packaging is one of the most promising green packaging materials using LCA (LifeCycleAssmcnt, "Ecological Cycle Assessment Method") technology for quantitative evaluation. At present, cartons, paper bags, paper barrels, and pulp molded products have become an important part of the modern packaging industry and are widely used in transportation packaging and food packaging.
