Problems solved by technology

However, the electrostatic adsorption force generated by the corona electrostatic effect it relies on will decay with time, requiring the timeliness of the combination of plastic and aluminum to be short, and the composite tightness is not strong enough

Embodiment Construction

[0027] 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 Mg2Si aluminum foil, which can significantly improve the tensile strength and el...

Abstract

The invention discloses at least one layer of plastic film and at least one layer of aluminum foil bonded by an adhesive in sequence, and finally bonded with a PVC film to form a plastic layer / aluminum foil layer / PVC layer, or a multi-layered plastic layer / aluminum foil layer / plastic layer / Aluminum foil layer / PVC layer, which is a high-seal cold stamping blister plastic-aluminum composite hard sheet composed of odd multi-layer composites. The film surface of the plastic layer is densely covered with tiny corona spots, and the aluminum foil of the aluminum foil layer contains silicon element, and is an aluminum alloy aluminum foil with a single surface. The multi-layer composite structure with plastic-aluminum toughness and brittleness complements each other, which slows down the damage of lattice slip deformation during the stamping and deep-drawing process of aluminum foil. The tensile strength has reached 93Mpa, and the elongation has reached 34%. Electrostatic attraction and surface adhesion formed by corona impact on the surface of the plastic film layer, no blistering and peeling resistance after compounding. When stamping the blister, it will not break, delaminate and deform. The tensile strength exceeds 10 percentage points of similar foreign products, and the elongation exceeds 5 percentage points. The cost performance is better than that of similar foreign products, and the price per ton can be reduced by 50-60%.

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...
