Product Description
Characteristics:
The Blister aluminum foil is designed for the lacquered foil intended to be used for the production of protective and safe packaging for pharmaceutical applications. Its main advantages are:
Total barrier protection against light, moisture, oxygen and other gases, and liquids.
It is strong and can be laminated with other materials. 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.
Good mechanical protection.
Light weight that allows use the minimum of transport and production space.
Applications:
Blister packs for pharmaceutical applications.
Cold forming blister packaging (Tropical blister).
Baochang supplies its product in reels of wide until 650 mm, with core of carton in 76 mm., maximum diameter of 400 mm. And maximum weight of 100 kg.
