Jun 19, 2017

The composite layer of the Lamination Film is a Lamination Film having three or more layers, and if it is a Lamination Film of two layers, there is no interlayer material of the Lamination Film. So what are the commonly used Lamination Film interlayer materials? What are the characteristics between them?

Packaging and printing industry commonly used Lamination Film of the middle layer of materials are aluminum, aluminum, nylon, PET film, kraft paper, coated paper, let us take a look at their own characteristics:

Aluminized film (VMPET): light transmission is weak, the proportion of: 1.4, commonly used thickness: 1.2C.

Aluminum foil (aluminum foil): opaque, higher purity, higher than the price of aluminum), the proportion of: 2.6, commonly used thickness: 0.7C.

Nylon (Nylon / PA): good strength, good sealing, for liquid, nozzle bags and vacuum packaging.

PET film: good resistance, good sealing, for liquid, nozzle bags and vacuum packaging.

Kraft paper: used as packaging materials, high strength, usually yellowish brown.

Coated paper: is a base paper coated with white paint made of advanced printing paper, good strength, good sealing, for liquid, nozzle bags and vacuum packaging.

These are the commonly used composite membrane of the middle layer of materials, Lamination Film interlayer material is the main role is to moisture, barrier odor, shading and so on. In addition to the Lamination Film of the middle layer of materials, there are composite membrane surface material and composite membrane of the lining material, the three are interrelated and different.
