Paper used for food packaging also needs to be hygienic, sterile, pollution-free, and paper bags and large plastic bags have no decoration and other advantages.
        Wrapping paper is widely used, the largest is food packaging, so it has the most machine specifications.

It is said that its characteristics are clean, non-bacterial, moisture-proof, oil-proof, anti-sticky, mold-proof, etc., which can keep food well.
