High sealing hot belt type packaging aluminium

Abstract

The invention discloses a high-sealing tropical-type packaging aluminum that is moisture-proof, volatilization-proof and ultraviolet radiation-proof. It consists of a composite aluminum foil composed of alternating layers of plastic film bonded to aluminum foil, and finally coated with adhesive. The number of alternately bonded layers of plastic film and aluminum foil is four or more, and the plastic film is a high factor plastic film. The present invention adopts the multi-layer composite structure of low-cost plastic film and aluminum foil to replace the nylon-bonded aluminum foil two-layer composite structure of similar foreign products. The hard and brittle problem caused by compounding also solves the technical problem of cracking, delamination, wrinkling and delamination when the multi-layer composite plastic aluminum is stamped into a blister with a depth of more than 7 mm, and is not resistant to stamping. Compared with similar foreign products, the cost has been reduced by more than 40%. Compared with similar foreign products, it is stronger and more resistant to pressure, greater toughness and tension, and higher sealing performance. And the ton price is lower and the time period is shorter.

Description

technical field [0001] The invention relates to a packaging material, in particular to a high-seal heat-sealed tropical packaging aluminum used for moisture-proof, volatilization-proof and ultraviolet radiation-proof. Background technique [0002] High-seal tropical packaging aluminum is a high-seal, moisture-proof, anti-drug volatilization, and anti-ultraviolet radiation packaging material used in high-end pharmaceuticals such as anti-inflammatory drugs, as well as chemical, food, and pharmaceutical industries. It is an emerging product of pharmaceutical packaging at home and abroad. The pharmaceutical packaging has extremely high requirements on the material, which requires the packaging material to punch out a trademark or logo depth of at least 6.5 to 8.5 wires on the surface of the packaging aluminum foil, and to shape it into a rectangular concave shape. The formed packaging aluminum shall not be broken, deformed, peeled off or delaminated. It is required that the th...

Problems solved by technology

[0003] The purpose of the present invention is to address the disadvantages of high cost in the prior art and only nylon bonded aluminum foil can be completed and solve the technical prejudice of easy cracking, delamination, wrinkling and delamination when packaging aluminum calendered blisters with a depth of more than 7 mm , to provide a multi-layer composite principle, which can make the plastic-aluminum film material enter the gold-plastic state, cooperate together to form a multi-layer composite sealing structure, and form a multi-layer sealed, stronger and pressure-resistant, more airtight high-sealing tropical type Packaging aluminum
