The Functions of PE Coated Paper

PE (Polyethylene) coated paper is a type of paper that has been coated with a layer of polyethylene. The PE coating provides various functions to the paper, including:
Moisture resistance: The PE coating helps to make the paper resistant to moisture, making it suitable for use in packaging applications where the contents need to be protected from moisture.
Grease resistance: The PE coating also provides the paper with resistance to grease, making it ideal for use in food packaging applications where grease resistance is necessary.
Heat sealability: PE coated paper can be easily heat sealed, which makes it ideal for use in the packaging of products that need to be sealed for freshness or to prevent tampering.
Printability: PE coated paper can be printed on using various printing techniques, making it ideal for use in packaging applications where branding and product information need to be displayed.
Tear resistance: The PE coating helps to improve the tear resistance of the paper, making it more durable and suitable for use in packaging applications where the contents need to be protected during transportation.
Barrier properties: The PE coating provides a barrier against oxygen, which makes it suitable for use in packaging applications where the contents need to be protected from oxidation.
Overall, PE coated paper is a versatile material that provides a range of functions, making it suitable for use in various packaging applications across industries.

The working principle of PE Coated Paper

PE (Polyethylene) coated paper is created by coating a layer of polyethylene on one or both sides of a paper substrate. The working principle of PE coated paper involves the interaction of the paper substrate and the polyethylene coating.
During the manufacturing process, the paper substrate is first coated with a layer of polyethylene, which is then bonded to the paper using heat and pressure. The PE coating provides various properties to the paper, such as moisture resistance, grease resistance, heat sealability, and printability, as mentioned earlier.
The working principle of PE coated paper is based on the unique properties of polyethylene. Polyethylene is a type of thermoplastic polymer that has low surface energy, which means that it is difficult for other materials to adhere to it. This property makes polyethylene an excellent material for creating a barrier against moisture, grease, and other liquids.
When the polyethylene coating is applied to the paper substrate, it forms a barrier layer that prevents moisture and other liquids from penetrating the paper. The polyethylene layer also provides a heat sealable surface, which can be used to seal the packaging and protect the contents.
In addition to the barrier properties, the polyethylene coating also improves the tear resistance of the paper, making it more durable and suitable for use in packaging applications where the contents need to be protected during transportation.
Overall, the working principle of PE coated paper is based on the interaction between the paper substrate and the polyethylene coating, which provides a range of properties that make it suitable for use in various packaging applications across industries.
