Summary of the invention
In order to overcome the problems referred to above, this is novel provides that a kind of combined strength bination is high, thermal deformation is little, and the food packaging aluminized complex film going bad can not occur because packaging bag barrier is poor content.
For achieving the above object, this novel technical scheme providing is:
A kind of high barrier aluminum-plating composite film, it comprises the first composite bed, the second composite bed and the 3rd composite bed; Described the first composite bed is provided with high-barrier PE nylon layer and the first bonding coat; Described the second composite bed is provided with aluminium coated and the second bonding coat; Described the 3rd composite bed is provided with the second bonding coat and hot sealing layer, and make described high barrier aluminum-plating composite film set gradually from the outer to the inner order be: high-barrier PE nylon layer, the first bonding coat, aluminium coated, the second bonding coat and hot sealing layer; Described hot sealing layer is polyethylene layer or cast polypropylene layer.
Between described high-barrier PE nylon layer and the first bonding coat, be provided with printed layers.
The thickness of described high-barrier PE nylon layer is 9 ~ 35 μ m.
Described aluminium coated is aluminized polyester film, and aluminium coated is that aluminized polyester film thickness range is 370-450 dust.
The optical density (OD) of described hot sealing layer of aluminizing is between 0.2-0.8.
the usefulness of technique scheme is:
1, this novel described composite package film is compared with two kinds of composite package films described in background technology, and barrier property is better, is not easy to occur curling, and content can not occur because packaging bag barrier is poor to go bad; Nylon in this novel barrier complex film is had outstanding performance to the barrier property of the gas such as oxygen and carbon dioxide in addition; and can keep high strength and rigidity in very wide range of temperatures; thermal deformation is little; water absorption rate is low; anti needling can be given prominence to, thereby meets the requirement of protection content and guarantee inner vacuum.
2, this novel employing has the necessarily heat sealable film of the amount of aluminizing, and its optical density (OD) is between 0.2-0.8, both can make whole packaging bag present certain metal-like and diaphaneity, there is again certain deadening function to oxygen and aqueous vapor, solved the barrier properties of packaging film and the two problem that can not simultaneously take into account of displaying property simultaneously.
3, heat-sealing post heat-seal place high-peeling strength; With the polypropylene comparison of aluminizing, this novel aluminium coated is very good in the peel strength at heat-sealing post heat-seal place, can not decay and improve on the contrary, has prevented that greatly the packaging causing because of material delamination from destroying.
