Application: it can be used for demanding places, composite structure with three layers,partly can use two layers instead of three layers. It is widely used for milk powder,coffee,cosmetics,jelly,wines,drinks ,pesticides and snackes packing etc,it can also extend the shelf lift of contents, have a good fragrance retention ,replace part of packaging foil composite structure, use for higher water resistance, improve for liquid packaging
Specification :
Thickness :12 MIC etc
Width:≤2100mm
Paper core 76mm(3″)\152mm(6″)
Features:
1.high adhesion between film and alumium layer after chemical treatment on the surface of film 2.Due to high adhesion of aluminium layer,No Al layer peels the shelf of life can be retained,3.a higher barrier can be achieved by increasing the thickness of Al layer.4.strong water resistance 5. high temperature resistance.
