What is blister pack
Blister pack is a popular packaging solution for tablet, capsule, pill, chewing gum, candy, and other small-size food, etc.. It consists of two parts: the lidding foil (commonly aluminum) and the semi-rigid formed cavity, both are good barrier to external factors, such as humidity and contamination for extended periods of lifetime.
Since the product is individually sealed into each blister, it is easy to carry and friendly to customer to consume as the using indication printed on the lid foils. Meanwhile the manufacturer’s name or logo printing is another good way to promote and market your products and company.
Structure of PTP blister foil
Aluminum blister foil is coated with primer and heat sealing lacquer on different side of plain aluminum foil, but without printing.
The primer coating is suitable for printing in customer’s plant, by solvent/ alcohol-base ink. It also withstands the high temperature of heating during blister packaging process, to guarantee the printing layout.
The heat sealing lacquer is food grade, and easy to seal with PVC, PVC/PVDC, Alu-Alu bottom foil, PP, etc, by heating on blister packaging machine.
Both soft and hard aluminum foil are used as the lid of the push-through pack (PTP).
By only a small stretching force, the cover foil hard temper can be broke relatively quickly; the unit-dose will be released easily, which is helpful for the weak patients or emergency.
On the other hand, soft aluminum foil is also being used as the closure; more force must be applied to get the drug since its higher stretching force. Thus, such pharmacutical packaging is considered to be children-resistant.
