Abstract
The utility model discloses a kind of high-barrier digestion resistant transparent packaging films, including laminated polyester film, high-isolation film layer, polyamide laminate film, layer of polypropylene foil and the first glue-line, the second glue-line, third glue-line, the bottom of the laminated polyester film is glued by the first glue-line and high-isolation film layer, the bottom of high-isolation film layer is glued by the second glue-line and polyamide laminate film, and the bottom of polyamide laminate film is glued by third glue-line and layer of polypropylene foil.Pass through the high-isolation film layer of the high compound sided corona treatment of combined strength bination binder of laminated polyester film, it is compound with polyamide laminate film to reuse binder, it is compound with layer of polypropylene foil to reuse binder, the performance of high-barrier and resistance to 135 DEG C of thermophilic digestions is reached, interior packing object can be shown again, by double sided corona treatment high-resistant diaphragms, the peel strength of product ensure that.
Description
Technical field
The utility model belongs to flexible packing material technical field, and in particular to high-barrier digestion resistant transparent packaging film.
Background technique
General resistance to 135 DEG C or less thermophilic digestions and shelf-life longer product, mostly at home is using foil laminated film, again
Conjunction intensity is good, and specific product structure is mostly: polyester film/adhesive/aluminum foil/adhesive/simple tension polypropylene film；Polyester
Film/adhesive/aluminum foil/adhesive/nylon film/adhesive/simple tension polypropylene film；Nylon film/adhesive/aluminium
Foil/adhesive/simple tension polypropylene film etc., although foil packaging film has many good qualities and characteristic, such as high temperature resistant prevents wearing
Pierce, be not easy to deform, high obstructing performance is prominent, resistance oxygen resistance is wet opaque, but since the deformability of aluminium foil is poor, stretch drawing by force
Or vacuumize rear aluminium foil and will receive destruction, its barrier property is substantially reduced, and cannot share well to customer demonstration package object.
Summary of the invention
The technical problem that the one side of the disclosure solves be to provide a kind of packaging product have high-barrier characteristic,
It can accomplish resistance to 135 DEG C thermophilic digestions below not only while but also show the product of interior packing well, client is allowed to have good body
The packaging film tested.
To achieve the above object, the utility model adopts the following technical solution, and the utility model includes laminated polyester film, height
Barrier film layer, polyamide laminate film, layer of polypropylene foil and the first glue-line, the second glue-line, third glue-line, the polyester film
The bottom of layer is glued by the first glue-line and high-isolation film layer, and the bottom of high-isolation film layer is thin by the second glue-line and nylon
Film layer is glued, and the bottom of polyamide laminate film is glued by third glue-line and layer of polypropylene foil.
Preferably, the high-isolation film layer is high-barrier polyvinylidene chloride film layer.
Preferably, the high-isolation film layer is through online sided corona treatment.
Preferably, the laminated polyester film is biaxially oriented laminated polyester film.
Preferably, the layer of polypropylene foil is simple tension layer of polypropylene foil.
Preferably, first glue-line, the second glue-line, third glue-line are identical or different adhesive layer.
The utility model leads to the high compound sided corona treatment of combined strength bination binder of layer compared with prior art, by polyester film
High-barrier polyvinylidene chloride film layer, it is compound with polyamide laminate film to reuse binder, reuses binder and unidirectional draws
Polypropylene stretched film layer is compound, has reached the performance of high-barrier and resistance to 135 DEG C of thermophilic digestions, and can show interior packing object；One
Kind new technology ensure that the peel strength of product by double sided corona treatment high-barrier film layers.
Detailed description of the invention
Fig. 1 is packaging film structure schematic diagram according to one aspect of the disclosure；
In figure: 1- biaxially oriented laminated polyester film, 2- high-barrier polyvinylidene chloride film layer, 3- polyamide laminate film, 4-
Simple tension layer of polypropylene foil, the first glue-line of 5-, the second glue-line of 6-, 7- third glue-line.
Specific embodiment
The utility model is further explained below in conjunction with specific embodiment, but limitation is not originally practical
It is novel, structure depicted in Figure of description, ratio, size etc., only to cooperate the revealed content of specification, for ripe
The personage for knowing this technology understands and reads, and is not intended to limit the utility model enforceable qualifications, therefore does not have technically
Essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size can be produced not influencing the utility model
Under raw effect and the purpose that can reach, the range that the revealed technology contents of the utility model can be covered should all be still fallen in
It is interior.Meanwhile cited such as "upper", "lower", "front", "rear", " centre " term in this specification, it is merely convenient to describe
It is illustrated, rather than to limit the enforceable range of the utility model, relativeness is altered or modified, and is changing skill without essence
It is held in art, when being also considered as the enforceable scope of the utility model.
Shown in Fig. 1, a kind of high-barrier digestion resistant transparent packaging film, including biaxially oriented laminated polyester film 1, high-barrier
Polyvinylidene chloride film layer 2, polyamide laminate film 3, simple tension layer of polypropylene foil 4 and the first glue-line 5, the second glue-line 6,
The bottom of third glue-line 7, the biaxially oriented laminated polyester film 1 passes through the first glue-line 5 and high-barrier polyvinylidene chloride film
Layer 2 is glued, and the bottom of high-barrier polyvinylidene chloride film layer 2 is glued with polyamide laminate film 3 by the second glue-line 6, and nylon is thin
The bottom of film layer 3 is glued by third glue-line 7 and simple tension layer of polypropylene foil 4, the first glue-line 5, the second glue-line 6, third
Glue-line 7 is adhesive layer, and the binder of adhesive layer is that polyurethane is binder.
Specific processing flow are as follows: through dry type compound working procedure coating binder and pass through biaxially oriented laminated polyester film 1
High-barrier polyvinylidene chloride film layer 2 after line sided corona treatment carries out composite curing, and dry type compound working procedure coats bonding again
Agent and 3 composite curing of polyamide laminate film, re-coating binder and 4 composite curing of simple tension layer of polypropylene foil.
Online corona is on the assembly line of processing, and film layer corona before composite curing operates.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
