PE coating, also known as polyethylene coating, is a very common and important industrial processing technology. Here is a more comprehensive introduction:

1. Coating material: Polyethylene

What is PE? Polyethylene is the most commonly used plastic, and plastic bags, cling film, mineral water bottles, and other items commonly found in our daily lives are all made from it. It itself has excellent waterproof, chemical stability, and flexibility.

Coating form: PE used for coating is usually in the form of particles, which are melted by heating and become liquid, and then attached to the substrate.

2. Main processing techniques

Coating: This is the most common way. Pour the melted PE plastic evenly onto the surface of the substrate (such as paper or cardboard) like a "waterfall", and then quickly cool and press it together. The "coated paper" you often refer to is made through this process.

Spray coating: Spray molten PE onto the surface of an object in an atomized form, suitable for irregularly shaped or items that require thicker coatings.

Dip coating: Immerse the object in PE melt and lift it up to form a uniform coating on its surface, commonly used for tool handles, etc.
