2. Core Understanding: Nature and Specifications of PTP H18
2.1 Product Definition and the Meaning of “H18”
PTP aluminum foil is a specialized material designed to form the sealing lidding for blister packs. It heat-seals to plastic films like PVC or PVDC, creating individual, protective cavities for items such as tablets, capsiwlau, and confectionery. The designation “H18” is key—it signifies the “Llawn caled” temper state. This means the foil is not annealed (meddalu) ar ôl rholio, resulting in a robust, rigid structure with fundamentally different properties compared to annealed, soft-temper (“O” themprem) ffoils.
2.2 Key Alloys and Material Composition
The predominant alloy for PTP H18 foil is 8011, an Al-Fe-Si series alloy celebrated for its excellent mechanical properties, ymwrthedd twll pin, and surface finish. The H18 temper further enhances these qualities, making it ideal for demanding applications. Alloys like 8021a 8079 are also utilized for specific performance needs, offering versatility for different packaging scenarios.
2.3 Core Parameter Comparison: H18 vs. Soft Temper Foil
The defining characteristics of PTP H18 stem from its hard temper. The table below contrasts its core parameters with those of soft-temper aluminum foil.
