[0003] General packaging paper is collectively referred to as paper packaging. The performance requirements of paper packaging mainly include the following aspects: high strength, low cost, good air permeability, and wear-resistant packaging are mostly used as shopping bags and document bags, such as kraft paper. Packaging paper with a smooth surface and high strength is mostly used as labels, clothing tags, and bottle stickers, such as bleached paper. Packaging paper supported by natural raw materials, non-toxic, high transparency, smooth surface, tensile resistance, moisture resistance, and oil resistance is mostly used for food packaging, such as cellophane. The raw materials for manufacturing cardboard are basically the same as those for paper. The only difference is hardness, thickness, strong rigidity, and easy processing. It is the main paper for sales packaging.
