First, the difference between white cardboard and copper paper

1, The hardness is different

This is one of the most intuitive differences between white cardboard tote bags and coated paper tote bags. Because white cardboard usually has certain stiffness requirements, the hardness of white paper cards is higher than that of coated paper.

2, The thickness is different

The thickness of white cardboard is generally between 0.27mm and 0.55mm, while the thickness of coated paper is generally only 0.06mm to 0.465. In general, white cardboard will appear thicker, but some specifications of coated paper will be more The white cardboard is still thick.

3, Different uses

White cardboard is mainly used for handbags, business cards, various certificates, invitations, desk calendars, postcards and the like. The biggest feature of these things is that they require strong abrasion resistance and are not easily damaged. The coated paper is mainly used to print the color inserts of product catalog, various exquisite advertisements, commodity packaging and so on.

4, Different manufacturing processes

White cardboard is a single or multi-layer bonded paper made entirely of bleached chemical pulp and fully sized; coated paper is a paint processing paper, typically bleached chemical wood pulp or partially bleached chemical grass pulp. A coated paper base paper is produced on a paper machine, and then the white pigment and other auxiliary raw materials are uniformly coated on the base paper on a coater, and finally dried and supercalendered.
