8011/8079 Coating Aluminium Foil for Pharmaceutical Packaging
Aluminium foil is widely regarded as the most effective barrier material in flexible packaging, giving almost perfect protection against light and suppressing any transport of matter. Foil is usually converted to flexible packaging laminates by traditional converting processes, such as lacquering or 2-component-adhesive lamination, but more and more extrusion coating and extrusion lamination are being used.
CHALCO coat's coated aluminium foil could be used for the production of protective and safe packaging for pharmaceutical applications. Moreover it can be made suitable for different applications like"push through" lids or preformed trays for tablets by using different alloys with different mechanical properties, such as blister packs for pharmaceutical applications; cold forming blister packaging, push through "lids".
Features:
1.Total barrier protection against light, moisture, oxygen and other gases, and liquids.
