[China Packaging Network News] In more than 30 years, China has gone through the development history of more than 100 years in Europe and the United States, basically completing a complete range of paper products packaging industry system. From papermaking, machinery and equipment, education and scientific research, to the production of paper products, China is completely independent and autonomous. It ranks first in the world in terms of total volume and growth rate, and has become a world leader in paper packaging. The following is a description of the paper packaging industry definition and classification:
Paper packaging has the advantages of easy processing, low cost, suitable for printing, light weight, foldable, non-toxic, odorless, and non-pollution, but it has poor water resistance and poor strength when wet. Paper packaging materials can be divided into two categories: packaging paper and cardboard.

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 often used as shopping bags and document bags, such as kraft paper. The paper surface is smooth, and the higher strength packaging paper is used as a label, a clothing tag, and a bottle sticker such as bleached paper. Supported by natural raw materials, non-toxic, high transparency, smooth surface, tensile, moisture-resistant, oil-proof wrapping paper, used for food packaging, such as cellophane. The raw material for making cardboard is basically the same as paper, as long as the difference lies in hardness, thickness, rigidity, and easy processing. It is the main paper for sales packaging.
