The main difference between composite paper and all-wood pulp paper lies in their manufacturing processes and materials.

Coffee packaging film is widely used for packaging coffee beans, coffee powder, instant coffee, and other products.

Coated paper is a composite material made by coating a layer of plastic film (such as PE) onto the surface of ordinary paper.

Aluminum-plastic film is a multi-layered structural material made of aluminum foil and plastic film through a special process.

an outer protective plastic film (approximately 40μm), a middle aluminum foil (6-12μm), and an inner heat-sealed plastic layer.

The main raw materials for coated paper include paper substrate and plastic film.

Since 2016, the coated paper industry has undergone profound optimization and upgrading under the combined effects of increasingly stringent environme

The quality inspection of laminated paper mainly relies on the following aspects:

Laminated paper, with its oil-repellent, waterproof, and heat-sealable properties, is widely used in various fields.

Coated paper is a composite material in which plastic particles are coated onto the surface of paper using a casting machine.

Color fading of aluminum foil is not a normal phenomenon and may be caused by poor raw material quality, environmental factors, or friction during use

Currently, the thickness of aluminum foil on the market typically ranges from 0.006 mm to 0.2 mm.
