PTP Aluminum Foil
PTP (Press Through Package) aluminum foil is the standard lidding material for push-through blister packaging. Our PTP foil features high barrier properties, excellent safety protection, and multiple opening options. It is widely used for moisture-sensitive pharmaceutical products, inhalation preparations, veterinary medicines, and pet medications. The foil provides complete protection against moisture, oxygen, and light, ensuring product stability throughout shelf life.

Printing and Variable Data on Lidding Foil: Practical Considerations
Batch coding, expiry dates, and serialization on lidding foil require careful planning of print methods, tolerances, and readability verification.
Recyclable Blister Packaging Under the EU PPWR: What to Specify Now
The EU Packaging and Packaging Waste Regulation pushes blister packs toward design-for-recycling, but recyclability depends on the material stream, the lidding and the collection scheme in each market. This note sets out how PVC, PVC/PVDC, PVC/APET laminates, APET and RPET sit against those requirements, and the specification points worth fixing before tooling and validation.
