What is extrusion laminating line?

Extrusion laminating line is a type of laminating process used primarily in industrial and packaging applications. Extrusion laminating line is a manufacturing process used to bond two or more layers of materials together by melting a thermoplastic resin (such as polyethylene, polypropylene, or EVA) and extruding it as a thin molten film onto a substrate. The molten polymer acts as an adhesive, bonding the substrate to another material when pressed between rollers and cooled.

How Extrusion Laminating line Works:

1.Materials (Webs): Two or more substrates (such as paper, foil, or film) are fed into the laminating machine.

2.Molten Resin: A thermoplastic resin (like polyethylene) is melted and extruded (forced) through a flat die.

3.Application: The hot resin is extruded directly onto one of the substrates.

4.Lamination: The second substrate is pressed onto the molten resin layer.

5.Cooling and Bonding: The materials are pressed together between rollers, cooled, and solidified into a single laminated sheet.

Laiyi packing extrusion laminating machinery to increase the laminating strength, a layer of adhesive chemicals (Ac agent) will be coated on the base material,and therbe dried immediately on line.This process requires a coating device and a drying device.

Oven cover is pneumatic with negaive-pressure to prevent hot-air from blowing out of the oven. With segmented temperaturezone, automatic constant temperature control, it ensures easy volatilization of solvents.

Common Applications:

Food and beverage packaging

(Food and beverage packaging)

Pharmaceutical packaging

Industrial wraps

Flexible packaging (e.g, snack wrappers, pouches)

Liquid cartons (e.g, milk, juice boxes)

Liquid cartons (e.g, milk, juice boxes)

Extrusion lamination is widely used in flexible packaging due to its efficiency and performance benefits. Let me know if you need more details and if you’d like a diagram or specific examples of products that use this method!
