In recent years, began to promote green packaging (environmental packaging)

1. Environmentally friendly packaging materials generally include reusable and renewable packaging materials, edible packaging materials, degradable materials and natural paper materials. Environmentally friendly packaging is embodied in the use of materials, minimal waste and energy saving, easy recycling and reuse, and packaging waste does not produce secondary pollution. Therefore, the choice of environmentally friendly packaging materials should comply with the basic principles of harmlessness, pollution-free, and renewable use.
To put it simply, it refers to packaging that saves resources, can be recycled after use, is non-toxic when burned, and occupies less farmland when landfilled, and can be biodegraded and decomposed. Although pure natural environmentally friendly packaging materials are pollution-free, they have high commercial costs and are a serious waste of earth resources. Composite environmentally friendly materials will become the mainstream of environmentally friendly packaging in the future because of their low cost, non-polluting, and easy recycling.

2. Eco-friendly paper and recycled paper
The environmentally friendly paper claimed by many companies in the current market does not actually belong to recycled paper; the EU international standard only contains recycled paper.

Recycled paper is produced from waste paper. And without adding any brighteners, fluorescent agents and other chemical agents, so the color of recycled paper is yellowish natural color, and environmentally friendly paper is paper produced from wood pulp and straw pulp. Recycled paper does not add any brighteners, fluorescent agents and other chemicals, so it shows the beauty of the paper's natural color, slightly yellowish paper; because it is not reflective, it is actually more conducive to protecting our eyes. Europe and Japan are more than a dozen Years ago, recycled paper has been regularly used as office and study paper.
