Pulp raw material

Paper packaging materials have various varieties, low cost, good processing, and printing performance, and certain mechanical properties, and waste can be recycled without environmental pollution. Food packaging paper (cardboard) should not only have bright color, uniform color uniformity, and high color fastness, but also high waterproof performance, and more importantly, high food safety. The main material of papermaking is pulp, which can be roughly divided into wood pulp, straw pulp, cotton pulp, and recycled waste paper. Virgin pulp refers to pure virgin fibers.
