Embodiment Construction

[0029]The figure shows the plastic layer 1 (polyester film or polyamide) bonded aluminum foil layer 2 formed by a dry compound machine, then bonded PVC layer 3 or multi-layer bonded plastic aluminum and finally bonded PVC cold Stamping type blister plastic-aluminum composite hard sheet. It can also be polyester (or polyamide) / aluminum foil / polyester (or polyamide) / aluminum foil or more layers of composite, and finally glue PVC. Wherein the first base material adopts heat-resistant polyester film (or polyamide film) with high mechanical strength and rigidity, scratchy surface. The polyester film is a foil film formed by two-way stretching of polyethylene terephthalate, or a nylon film made of two-way stretched nylon resin. The thickness of the aluminum foil is selected to be 0.02mm-0.06mm. On the basis of the traditional aluminum-magnesium alloy, silicon is added to form a new strengthening phase Mg 2 Si aluminum foil, can significantly improve the tensile strength and elonga...

Abstract

A laminated hard plastics / aluminium plate with surficial PVC layer, and high sealing nature and able to be shaped by punch is prepared from at least one polyester (or polyamide) film treated by corona impact, at least one aluminium foil and one surficial PVC film through adhering them together by use of high-adhesion adhesive.

Description

technical field [0001] The invention relates to a new blister packaging material for filling medicines, in particular to a new blister plastic-aluminum composite hard sheet packaging material capable of punching out medicine particles. [0002] The invention also relates to the production process of the packaging material. Background technique [0003] In order to facilitate the packaging and carrying of granule medicines, common PVC hard sheets are commonly used in the known technology to punch out transparent blisters that contain medicine granules to seal the medicines. Due to the large amount of water vapor permeation of the PVC transparent body material, the oxygen barrier is not ideal enough, and the light radiation including ultraviolet light cannot be blocked. Therefore, the known technology fails to fundamentally solve the problem that the medicine is volatile, easily affected by moisture, and deteriorated by light. The quality problem of double reduction makes the...
