Understanding of PTP aluminum foil

PTP aluminum foil is an aluminum foil used for pharmaceutical packaging. It was formed in Europe in the 1930s and is referred to as PTP (Press Through Packaging). PTP foil is mainly used for aluminum-plastic blister packaging of pharmaceutical tablets, capsule, pilules, lozenges, ecc. It can also be used for blister packaging of food, health products, candy, ecc. The packaging used for pharmaceutical blister materials will account for about 60% à 70% of the tablet and capsule packaging of pharmaceuticals in the future, and is one of the pharmaceutical packaging materials with the best development prospects at present.

Structure of PTP medicinal aluminum foil: The structure of foglia d'aluminiu PTP usually includes a protective layer (OP), a printing layer, an aluminum foil layer (AL) and an adhesive layer (VC). In the aluminum-plastic blister packaging of pharmaceuticals, this packaging method first blister-forms a transparent plastic hard sheet, then fills solid pharmaceuticals such as tablets, pills or granules, capsule, ecc. in the groove, and then heats and bonds them with the aluminum foil coated with an adhesive to form an independent sealed package. This unique multi-layer structure ensures the characteristics of ptp aluminum foil.

What are the characteristics of PTP aluminum foil?

Oxygen barrier, moisture resistance, bona sigillatura: PTP aluminum foil can effectively isolate air and water vapor, protect the contents from contamination, and ensure the long-term preservation of the contents of the package.

Stampabilità: The surface of PTP aluminum foil can be coated with a coating machine, and text patterns can be printed by gravure printing technology and roller coating method, and coated to give it a beautiful appearance and high anti-counterfeiting properties.

Heat sealability: PTP aluminum foil uses a non-peelable heat seal coating, which can be heat-sealed with various plastic substrates, such as PVC hard sheets, ecc., and is suitable for blister packaging in the fields of medicines and food.

Excellent mechanical properties: PTP aluminum foil has good heat resistance, low temperature resistance, and corrosion resistance, and is suitable for high-speed automated packaging in various environments.

Easy to puncture: PTP aluminum foil uses hard aluminum foil as the cover material, which is convenient for consumers to tear off the aluminum foil and take out medicines or food, and is convenient and quick to use.

Thickness range: The thickness range of PTP aluminum foil is usually 0.018-0.03mm. Aluminum foils of different thicknesses provide different degrees of protection for packaged items. You can choose the appropriate thickness according to actual needs.

Material and alloy state: The material of PTP aluminum foil is generally pure aluminum or alloy, such as 8011-H18 alloy, which has good light reflection ability and strength.

PTP aluminum foil is widely used in the pharmaceutical, food, cosmetics and other industries for its excellent gas barrier, moisture resistance, printability, heat sealing, mechanical properties and easy puncture.
