Alu alu bottom foil in pharmaceutical packaging

Alu alu bottom foil 8011 8021 8079 0.02-0.075mm are used as the base material for making laminated film in pharmaceutical packaging. At present, aluminum-plastic composite film is commonly used in medicine packaging industry, such as cellophane and aluminum foil and polyethylene composite (PT/AL/PE), polyester and aluminum foil and polyethylene composite (PET/AL/PE), that is, aluminum foil and plastic film to stick by mixture is laminated or extruded and composed of a base layer, a printing layer, a high barrier layer and a sealing layer, the base layer is outside, the heat sealing layer is included, and the high barrier layer and the printing layer are located in the middle.

The base material of the alu alu foil composed film is required to have excellent mechanical properties, good gloss printability, good transparency, high barrier property, safety, non-toxicity, and no heat sealability. The alu alu foil base has the features of:
(1) Strong air barrier, anti-oxidation, waterproof and moisture-proof.
(2) Strong mechanical properties, high anti-blasting performance, strong puncture and tear resistance.
(3) High temperature resistance (121 ° C), low temperature resistance (-50 ° C), good oil resistance and good aroma retention performance.
(4) Non-toxic and tasteless, in line with food and pharmaceutical packaging hygiene standards.
(5) Good heat sealing performance, softness and high barrier property.
(6) Layout requirements are strict, no black oil, scratches, small black silk, bright line, roll printing concave and convex points, mosquitoes and other phenomena.
