Blister Aluminum Foil Sheet Materials

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.
Technical Data:

Aluminum foil from 20 to 50 µ M with colorless primer lacquer or with white lacquer on one side and heat sealing lacquer to PVC/PVDC on the other side.

Coating properties: Colorless Primer and Coloured Lacquer:

Excellent adhesion to aluminum foil (resistant to adhesive tape test).
Good printing results using nitrocellulose inks and UV inks. (Inks' resistance is responsibility of the printer).
Resistant to heat sealing temperature (max. 220º C 1s).
Water resistant (30 min at room temperature).

Heat sealing lacquers:

Water resistant (30 min at room temperature).
Resistant to boiling water (5 min/100º C).
Lacquer porosity (15 min) < 5 pores/m2 (20g CuSO4 / 50CC HCl(35%) /1000CC. H2O).
Sealable to PVC/PVDC
Peel strength to PVC > 7.5 N/15mm. (150º C, 40 kg, 1s).
Recommended alloys: 8011 H18 Customer can specify its needs in order to choose the best thickness, alloy and temper of the metal.
