What Are The Methods For The Preparation Of Lamination Film?
Jul 11, 2017

Lamination Film refers to a variety of plastic and paper, metal or other materials through the laminated extrusion, coextrusion and other technology to the substrate together to form a multi-layer structure of the film. So you know what is the common structure of the Lamination Film for food packaging?

PE / PE, PET / PE, PVC / PE, NY / PVDC, PE / PVDC, PP / PVDC and so on.

Three-layer compound such as BOPP / PE / OPP, PET / PVDC / PE, PET / PT / PE, PT / AL / PE, wax / paper / PE and so on.

Four layers such as PT / PE / BOPP / PE, PVDC / PT / PVDC / PE, paper / aluminum foil / paper / PE and so on.

Five-layer composite such as PVDC / PT / PE / AL / PE and so on.

Six-layer composite such as PE / paper / PE / AL / PE / PE and so on.

The Lamination Film is a separation membrane composed of a microporous membrane or an ultrafiltration membrane and a dense homogeneous film having a thickness of only 0.1 to 0.25 m as a barrier layer on its surface. So that the amount of material through a great increase. Here to explain to you how to prepare the Lamination Film is divided into several categories?

The preparation method is divided into four categories:

(1) a lamination method, first preparing a thin dense homogeneous membrane, and then laminated on the microporous support film;

(2) dip coating method, the polymer solution dip on the microporous membrane, and then dry, the active monomer or prepolymer solution can also be dipped in microporous membrane, with heat or radiation curing;

(3) a plasma vapor deposition method, and a homogeneous film is formed on the surface of the microporous support film by plasma glowing;

(4) interfacial polymerization, on the surface of the microporous support film, with the active monomer interface polymerization.
