Paper packaging has the advantages of easy processing, low cost, suitable for printing, light weight, foldable, non-toxic, tasteless, and pollution-free, but it has poor water resistance and poor wet strength. Paper packaging materials can be divided into packaging paper and cardboard.
Ordinary paper can be used for packaging, but in order to make the packaged products reach the specified strength index and ensure that the packaged products are intact, all packaging papers should have high strength, low moisture, low air permeability, and no corrosive substances for packaging products. And has good printing performance. Only paper with these properties can be used for packaging of various products. In order to meet the needs of different packaging products, base paper is often processed into packaging paper with various special properties.
