PTP Aluminum Foil (Press Through Packaging Aluminum Foil) is a high-performance aluminum foil material specifically designed for pharmaceutical packaging, primarily used in blister packaging for medications. It effectively protects drugs from moisture, oxidation, and light, extending their shelf life while ensuring stability and safety. PTP aluminum foil is widely used for tablets, capsules, and pills, making it an essential packaging material in the modern pharmaceutical industry.
PTP aluminum foil consists of high-purity aluminum foil laminated with polyester or polypropylene plastic film, forming a multi-layer structure that includes:
Protective layer (OP)
Outer printing layer
Aluminum foil base material (AL)
Inner printing layer
Adhesive layer (VC)
Common aluminum alloys for PTP aluminum foil include 8011, 8021, and 8079.
