AlOx-PET film features

1. Environmental protection, high transparency, microwave heating, metal detection;

2. High barrier: water and oxygen resistance ≦2.0(oxygen resistance is better than K film 8-15ml/(m2·24h)·23℃0%RH)

3. The barrier property is stable and little affected by relative temperature (obviously better than EVOH co-extruded film and PVA coated film).

4. Excellent heat resistance, can be boiled or even steamed;

5. The best economic cost performance.

Typical application examples:

1. Pet-alox /PU/PE(or CPP) blank film

2.PET(or OPP)+INK/PU/AlOx-PET12/PU/PE(or CPP) measured composite film, water resistance 1.1g/(m2·24h), Oxygen resistance 0.95ml/(m2·24h)

3.PET-AlOx/PU/PA+INK/PU/PE composite film, water resistance 1.17g/(m2·24h), Oxygen blocking 0.81ml/(m2·24h)

4. Pet-alox /PA/RCPP high barrier packaging

5.BOPP (or PET)/Alumina PET/PE (or CPP) mask bag (T/GDBZ 008-2021) Note,

GB/T 40266-2021 "Food packaging oxide barrier transparent plastic composite film, bag quality General Rules" more list structure is: AlOx-BOPET/PE(CPP), BOPET/AlOx-BOPET/PE(CPP), BOPA/AlOx-BOPET/PE(CPP), AlOx-BOPET/ BOPET/PE(CPP), BOPP/AlOx-BOPET/PE(CPP),

etc. Notes:

1. No protective coating AlOx-PET film, generally not used for printing, but as a composite substrate, and avoid over roll and machine wrinkling phenomenon, is conducive to maintaining the high barrier properties of the evaporation coating;

2. The selection of adhesives with better softness and the reduction of cohesion failure factors are more conducive to improving the stripping strength of the evaporation coating;

3. When the content is acid-alkaline, it is necessary to test the AlOx layer resistance (after the content acceleration test, compare the composite strength and barrier data of the composite film, or the deterioration of the content) or design an effective barrier layer;

4. Improper operation during boiling/cooking will cause the extension and deformation of the packaging bag, which will destroy the barrier property of the composite material;
