Good transparency, waterproof and dampproof property and good patience (such as oil resistivity, lower temperature resistance, resistance to chemical reagents), good processability with
And suitable mechanical strength, realize the moisturizing of packaging article, protect fragrant, fresh-keeping and aesthetic function.
In prior art, the material for packaging film mostly is monolayer thermoplastic's resin, such as polyolefin (such as PP, PE), polyamides
There is amine (such as nylon 6) and polyester (such as PET), these materials higher transparency, excellent mechanical performance and easy processing to process
Characteristic, thus be processed to thin film, sheet material and bottle etc. in interior various packing articles.But, these thermoplasticity
Resin is very poor to the barrier of various gaseous matters especially oxygen, and therefore packing material therein is easy to become due to oxidation
Matter.
The content of the invention
This utility model is directed to the deficiencies in the prior art, there is provided a kind of to have high barrier to gas, moisture
Food package film, realizes the guaranteeing the quality of packing article, moisturizing, protects fragrant and fresh-keeping function.
This utility model solves the technical scheme that its technical problem adopted：A kind of packaging for foodstuff of high obstructing performance
Film, including multi-layered film body, are followed successively by from the inside to the outside in contact and connect the external layer of layer, barrier layer and impact-resisting wear-resisting, and the anti-impact is resistance to
Grind between external layer and the barrier layer and the barrier layer and the contact in connect and be provided between layer adhesive layer, its
It is characterised by, the barrier layer is that PEN Rotating fields are laminated the layer for constituting with polyvinylidene chloride Rotating fields
Structure.
Further, the external layer of the impact-resisting wear-resisting is BOPET layers, and layer is connect in the contact for PE layers.
Further, the adhesive layer is resin-bonded layer, and the resin-bonded layer is EAA layers.
Further, the thickness of the barrier layer is 3～20 μm, and the thickness of the external layer of the impact-resisting wear-resisting is 5～30 μm,
The thickness that layer is connect in the contact is 15～50 μm, and the thickness of the adhesive layer is 1～10 μm.
Further, the thickness of the resin-bonded layer is 3～20 μm.
The beneficial effects of the utility model：
This utility model is laminated what is constituted using PEN Rotating fields with polyvinylidene chloride Rotating fields
Rotating fields as barrier layer, with higher gas barrier property, physical and mechanical propertiess, chemical stability and heat resistance；Adopt
With BOPET layers as the external layer of impact-resisting wear-resisting, as outermost layer, with fabulous wearability, folding resistance, pinhole resistance and anti-
Lancinating etc., its tensile strength be nylon membrane, 3 times of PC films, impact strength is 3-5 times of BOPP film, and heat-shrinkable pole
It is little, solve the problems, such as in prior art with the product of housing material have be difficult to print；Using PE layers as in contact
Layer is connect, is a kind of odorless, tasteless, nontoxic thermoplastic as packaging film innermost layer, chemical stability is preferable, chemically-resistant
Medicine, low temperature resistant, water absorption rate is low, it is adaptable to the packaging for foodstuff of water resistant, oil resistant etc.；Using EAA as resin-bonded layer, can play
The protective effects such as puncture resistant, anti tear, anti-corrosion.
Description of the drawings
This utility model will be illustrated by example and with reference to the appended drawing, wherein：
Fig. 1 is structural representation of the present utility model.
In figure：1st, the external layer of impact-resisting wear-resisting, 2, barrier layer, 3, connect layer in contact.
Specific embodiment
Below with reference to drawings and Examples, this utility model is described in detail.
