High sealing cold pressing type packaging aluminium

Abstract

The invention discloses a moisture-proof, volatilization-proof and ultraviolet radiation-proof high-seal cold stamping type packaging aluminum packaging material. It consists of a plastic film layer bonded to aluminum foil, followed by a PVC film layer. It also includes an intermediate adhesive layer inserted between the plastic film layer and the aluminum foil layer. The intermediate adhesive layer is formed by cross-bonding the plastic film layer and the aluminum foil layer. . And all the plastic film layers and the aluminum foil are cross bonded, wherein the plastic film is a high factor plastic material. The invention overcomes the technical prejudice that only nylon-bonded aluminum foil can be completed and is easy to break, delaminate, wrinkle and delaminate when the packaging aluminum hard sheet is stamped into various concave blisters. It has fundamentally broken through the monopoly position of foreign similar products with high price and dominating the market. The formed packaging material has superior quality and performance, and is stronger and more pressure-resistant than similar foreign products, with greater toughness and tension, and has higher airtightness and cost performance. Packaging The aluminum forming packaging process is not easy to break, fall off, break and deform.

Description

technical field [0001] The invention relates to a packaging material, especially a packaging material used for moisture-proof, anti-volatility and anti-ultraviolet radiation Background technique [0002] High-seal cold stamping packaging aluminum is a packaging material with high sealing performance, anti-drug volatilization, and anti-ultraviolet radiation used in the high-end pharmaceutical industry such as anti-inflammatory drugs. It is an emerging product of pharmaceutical packaging at home and abroad. The pharmaceutical packaging has extremely high requirements on the material, and it requires the packaging material to be punched out on the surface of the packaging aluminum foil to contain the concave shape of the medicine particles, with different shapes. The formed packaging aluminum shall not be broken, deformed, peeled off or delaminated. It is required that the thickness of high-sealed cold stamping packaging aluminum should reach more than 14 wires. At present, t...

Problems solved by technology

[0003] The purpose of the present invention is to solve the disadvantages of high cost of the existing technology and only nylon bonded aluminum foil can complete and solve the technology of easy cracking, delamination, wrinkling and delamination when the packaging aluminum hard sheet is stamped into various concave blisters Prejudice, to provide a high-seal cold stamping packaging aluminum that can make the plastic-aluminum film material enter the gold-plastic state, and cooperate to form a multi-layer composite sealing structure, which is stronger, pressure-resistant, more airtight, and low in cost.
