Description
Technical field
The utility model is related to a kind of composite membranes, and in particular to a kind of high-barrier anti-medium composite membrane.
Background technology
When being consumed in fast food restaurant, the sauce that many food are equipped with is packed using inner wrapping form, with take with
, this sauce packet is easy to carry, safety and sanitation, using quick, favored by many people.Usually, this inner wrapping
Bag is substantially using made of composite membrane, and common composite membrane is printing layer, ink layer, the first gluing successively from outside to inside
Layer, barrier layer, the second adhesive layer and hot sealing layer.
Such as application No. is 200920186972.9 Chinese utility model patents to disclose a kind of answering for tartar sauce
Film is closed, which is followed successively by polyethylene terephthalate (PET) layer, aluminium foil layer, ethylene-acrylic acid copolymer from outside to inside
Object (EAA) layer, bimodal low-density degree polyethylene (SPPE) layer, metallocene PE blending and modifying resin (MLDPE) layer.
The composite membrane, as barrier layer, but other adhesive layers is not arranged only with aluminium foil between aluminium foil layer and pet layer, not only
Adhesion performance between the two is inadequate, and barrier property is not high, and pet layer is weaker to the protective effect of aluminium foil layer, does not have anti-
The effect of medium.
Utility model content
Present invention purpose is to provide a kind of high-barrier anti-medium composite membrane.
For achieving the above object, the technical solution of the application is as follows：
A kind of high-barrier anti-medium composite membrane, including printing layer from outside to inside, ink layer, the first adhesive layer, barrier layer,
Second adhesive layer and hot sealing layer, first adhesive layer are to gather inclined dimerized vinyl film layer.
The first adhesive layer of the application is made of inclined dimerized vinyl material is gathered, and gathers inclined dimerized vinyl not only with good
Adhesive property, and itself be also barrier resin, there is anti-medium effect；Therefore printing layer and barrier can be bonded effective
While layer, dual barrier effect is played, the composite membrane of the application is made to have both anti-high obstructing performance and anti-medium effect.
In above-mentioned high-barrier anti-medium composite membrane, the barrier layer is aluminium foil layer.
In above-mentioned high-barrier anti-medium composite membrane, the printing layer is bidirectional stretching polypropylene film layer.It is two-way
Stretched polypropene film not only has good barrier property, but also has excellent tearing guidance quality, is further enhancing resistance
Assign composite membrane excellent tearing guidance quality while separating performance.
In above-mentioned high-barrier anti-medium composite membrane, second adhesive layer is that ethylene-beta-unsaturated esters copolymer is thin
Film layer.The bonding force of ethylene-beta-unsaturated esters copolymer film and aluminium foil is fabulous, and adhesive property is strong.
In above-mentioned high-barrier anti-medium composite membrane, the hot sealing layer is polypropylene casting film layer.Polypropylene stream
Prolonging film not only has good heat sealability, but also barrier property and anti-medium effect are also very excellent.
In above-mentioned high-barrier anti-medium composite membrane, outer barrier layer is additionally provided with outside the printing layer.
In above-mentioned high-barrier anti-medium composite membrane, the outer barrier layer is ethylene-vinyl alcohol copolymer film layer.
Ethylene-vinyl alcohol copolymer film has excellent gas barrier property, can either prevent ambient atmos from entering in packaging, can also prevent from wrapping
The fragrance for packing content dissipates, to further enhance the barriering effect of compound.
Present invention also provides a kind of tomato sauce packaging bag, which is compound using the high-barrier anti-medium
Film is made.
Compared with prior art, the beneficial effects of the utility model are：
(1) the first adhesive layer of the application is made of inclined dimerized vinyl material is gathered, and gathers inclined dimerized vinyl not only with good
Good adhesive property, and itself be also barrier resin, there is anti-medium effect；Therefore can it is effective bond printing layer with
While barrier layer, dual barrier effect is played, the composite membrane of the application is made to have both anti-high obstructing performance and anti-medium effect.
(2) printing layer of the application is bidirectional stretching polypropylene film layer, and bidirectional stretching polypropylene film not only has good
Good barrier property, and there is excellent tearing guidance quality, it is excellent that composite membrane is assigned while further enhancing barrier property
Different tearing guidance quality.
(3) hot sealing layer of the application is polypropylene casting film layer, and polypropylene casting film not only has good heat-sealing
Property, and barrier property and anti-medium effect are also very excellent.
(4) the application is also externally provided with ethylene-vinyl alcohol copolymer film layer in printing layer, and ethylene-vinyl alcohol copolymer is thin
Film has excellent gas barrier property, can either prevent ambient atmos from entering in packaging, also can prevent the fragrance of packaging bag content from disappearing
It dissipates, to further enhance the barriering effect of compound.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of high-barrier anti-medium composite membrane of the utility model.
Specific implementation mode
