Laminated paper is a type of composite material made by bonding paper with plastic film, typically PE (polyethylene) or PET (polyester), through heat or adhesive lamination. This process enhances the paper’s strength, smoothness, and moisture resistance, allowing it to perform better than standard paper in demanding packaging and industrial applications.

It combines the natural printability and flexibility of paper with the durability and protective qualities of plastic. The product features smooth, glossy rolls made of Paper and PE, customizable in width and thickness to meet specific client requirements.

1. What Laminated Paper Is Made Of

Laminated paper consists of two or more layers:

1. Base Layer (Paper): The main structural layer, often made of kraft, white, or coated paper.

2. Lamination Layer (Plastic Film): Usually polyethylene (PE), polypropylene (PP), or polyester (PET), which provides barrier protection and smoothness.

The bonding is achieved through either extrusion lamination (melting the plastic film directly onto the paper) or adhesive lamination (using water-based or solvent adhesives).
This results in a stable, sealed surface that protects the inner paper from moisture, grease, and tearing.

2. Main Features and Advantages

A) Moisture and Grease Resistance

The plastic coating forms a barrier that prevents water or oil from penetrating the paper, making it ideal for food packaging, industrial wrapping, and insulation liners.

B) Strength and Durability

The laminated structure significantly improves the tensile and tear strength of the paper, ensuring it can withstand high-stress conditions such as heavy packaging, folding, or sealing.

C) Smooth and Glossy Surface

The lamination layer provides a clean, polished finish that enhances print quality and brand appearance, especially for retail packaging and labeling products.

D) Customizable Size and Thickness

Manufacturers can adjust width, thickness, and roll length based on specific production needs. This flexibility supports OEM/ODM customization for multiple industries.

E) Heat Sealability and Barrier Function

PE-laminated paper can be heat-sealed and acts as a partial vapor or gas barrier, maintaining the freshness of packaged materials and protecting sensitive products.

Summary

Laminated paper is a high-performance composite material combining the natural flexibility of paper with the protection and durability of plastic. Its structure—made from Paper and PE—provides excellent moisture resistance, tear strength, and printing adaptability, while also allowing customizable width and thickness according to customer requirements.

Whether used in industrial packaging, adhesive backings, or food-grade wraps, laminated paper offers a reliable, versatile solution that enhances both product protection and visual appeal.
