Functions of PE Coated Paper Sheet

A PE Coated Paper Sheet is a composite material created by laminating a layer of Polyethylene (PE) plastic onto a paperboard substrate through a hot-melt process. Its core function is to endow the paper with superior protective and processing properties, as detailed below:

1. Excellent Moisture and Water Resistance

   The PE layer forms a continuous, impermeable barrier that effectively blocks water, moisture, and other liquids. This makes it an ideal choice for liquid packaging (e.g., milk, juice cartons) and packaging for moist or frozen goods (e.g., frozen food, takeaway containers), preventing the paper from becoming soft or disintegrating.

2. Superior Oil and Grease Resistance

   The coating effectively prevents the penetration of oils and greasy substances. This makes it highly suitable for packaging greasy foods like fried items, oily snacks, and butter, preventing stain-through and maintaining the package's structural integrity and appearance.

3. Excellent Heat Sealability

   The PE coating melts upon heating and solidifies quickly upon cooling. This property allows PE coated paper sheets to be rapidly and securely formed into sealed packaging containers (e.g., beverage cups, takeaway boxes, stand-up pouches) through heat-sealing processes, ensuring package integrity and the hygiene of the contents.

4. Enhanced Physical Strength and Durability

   The PE coating adds toughness, tear resistance, and puncture resistance to the paper. It makes the packaging more resilient to impacts, abrasion, and handling during shipping and stacking, while also providing strong seal integrity to prevent leaks at the seams.

5. Good Printability

   The surface is smooth and uniform, providing an excellent base for high-quality color printing. This allows for attractive graphics and branding information, enhancing the product's market appeal.
