This article provides a systematic analysis of PTP aluminum foil rolls, offering a complete industry reference from basic definitions to procurement strategies.
1. PTP Roll me letër alumini: Definition and Structure
PTP stands for “Shtypni përmes paketimit,” and its core material is the PTP aluminum foil roll. Është një fletë alumini e përbërë e krijuar posaçërisht për paketimin farmaceutik me blister.
Typical Three-Layer Structure:
- Shtresa e jashtme (Shtresa e shtypjes): Carries drug name, brand, dozimin, and other information, serving as a crucial interface for branding and regulatory labeling.
- Shtresa e mesme (Nënshtresa me letër alumini): Typically aluminum alloy foil with a thickness of 20-30μm, providing the core barrier properties and mechanical strength.
- Shtresa e brendshme (Veshje me vulosje të nxehtësisë): When heated on the blister packaging machine, it bonds firmly with blister base materials like PVC or PVDC, forming a sealed package.
This structure ingeniously unifies “secure sealing” me “shtytje e lehtë” access.
