Pharmaceutical foil
Aluminum foil has been widely used in drug packaging because of its non-toxic, high light shading, oxygen resistance and moisture resistance. With the development of technology, in addition to the traditional aluminum foil for blister packaging (PTP), aluminum foil is also combined with various plastic and paper materials as pharmaceutical packaging materials, such as double foil, strip foil, cold forming aluminum foil, aluminum suppository foil, composite film, etc.
Main categories of pharmaceutical foil
PTP blister foil
Cold form foil
Lamination foil
Suppository foil
PTP Blister foil
PTP aluminum foil has the characteristics of oxygen resistance, moisture-proof, leak-proof, pollution-proof and light-proof, which can effectively protect drug packaging. PTP aluminum foil with heat sealing lacquer ensures excellent heat sealing effect with PVC, PVDC/PVC, PP and other plastic based materials.

What you care about pharmaceutical foil
Structure of pharmacetical foil
Unprinted blister foil
Structure: Primer/Alu/HSL
Primer: 1±0.2gsm
Alu: 20mics, 25mics, 30mics
HSL(heat seal lacquer): 3±1gsm（recommended）
5±1gsm
7±1gsm
Primer-Unprinted blister foil, also known as NC foil, can be printed by customers themselves.
The desired contents should be printed on the primer side, primer can holds the ink in place so that the ink is very firm after printing.
HSL-Heat seal lacquer, which can be heat seal with PVC, PVDC, Alu alu and other materials under certian pressure and temperature.
Heat seal lacquer of 3gsm has very good sealing performance, which is enough for sealing needs of drugs, and the cost is low, is the recommended choice.
Heat seal lacquer of 5gsm and 7gsm have better sealing performance, but the cost is expensive. They are not recommended for price sensitive customers.
Printed blister foil
Structure: OP/Ink/Alu/HSL
Alu: 20mics, 25mics, 30mics
HSL(heat seal lacquer): 3±1gsm（recommended）
5±1gsm
7±1gsm
OP-Printed blister foil is ready to use foil, which already printed with the logo, name of the drug and other contents.
After printing on the surface of aluminum foil, the ink is easy to fall off, so need to coat the over lacquer to protect the ink, make it firm and not falling off.
Double sides printing-Due to the needs of product design, sometimes the HSL side also needs to print colors, such as gold, pink and even patterns.
