Which industries are coated paper used in?

Coated paper is a composite material in which plastic particles are coated on the surface of the paper through a casting machine. The main feature is that the composite material can be oil-proof, waterproof (relative) and heat-sealed.

1. The purpose of coating

Physically isolate water, drinks, food and paper; allow paper to be heated and formed into paper cups.

2. Laminate raw materials

PE particles: PE polyethylene – food-grade plastic, waterproof, oil-proof and leak-proof

PLA particles: degradable; waterproof, oil-proof and leak-proof; comparing with the PE coated,the price is more higher,but more environmentally friendly and degradable.


3. Characteristics of single-sided and double-sided lamination

Single-sided coating: single-sided PE coating, the coating surface is the forming joint surface, generally used to hold hot drinks or normal temperature food.

Double-sided coating: double-sided PE coating, both sides of the paper are coated; the outer wall of the paper cup and bowl for cold drinks will form condensed water, which will penetrate into the paper, so that the paper will soften and cannot be used normally; so it needs to be used in the paper cup and bowl. The outer wall of the paper is also coated to prevent water vapor from penetrating into the paper.

Special products: According to the appearance requirements, the gold foil and silver foil are laminated; the combination method: base paper + lamination + gold foil and silver foil + lamination, a total of 4 layers


1). Chemicals: desiccant packaging, preservatives;

2). Food: tea packaging, melon seed bags, bread bags, hamburger packaging, sugar packaging, coffee packaging bags;

3). Paper: coated paper packaging, light-coated paper packaging, copy paper (neutral paper);
