Abstract
The utility model discloses a kind of superhigh temperature boiling packaging films, including laminated polyester film, the bottom of laminated polyester film is glued by the first glue-line and aluminum foil film layer, the bottom of aluminum foil film layer is glued by the second glue-line and polyamide laminate film, the bottom of polyamide laminate film is glued by third glue-line and layer of polypropylene foil, and the polyamide laminate film is through upper and lower two-sided sided corona treatment.By the high combined strength bination binder of laminated polyester film and aluminum foil film layer composite curing, the polyamide laminate film for reusing binder and upper and lower two-sided corona is compound, finally compound using binder and simple tension layer of polypropylene foil.This is novel with high combined strength bination and high barrier resistance to 140 DEG C of superhigh temperature boilings again.
Description
Technical field
The utility model belongs to flexible packing material technical field, and in particular to superhigh temperature boiling packaging film.
Background technique
Steaming prod is according to the temperature of sterilization point: low temperature boiling, and for general control at 100 DEG C, 30 minutes, another kind is 85
DEG C, 15 ~ 30 minutes, pasteurize；Low temperature boiling, condition are control temperature a certain particular temperature values within the scope of 100 ~ 120 DEG C
Sterilization 30 minutes；Medium temperature boiling is that control temperature is sterilized 45 minutes at 121 DEG C or so；High temperature sterilization packaging, condition are control temperature
Degree reaches 135 DEG C of sterilizations 15 minutes or more；There are also ultra high temperature short time sterilization, temperature is more than 140 DEG C, and the time was at 15 seconds or more.
And common cooking disinfection is generally 121 DEG C or less products and has more than 135 DEG C of thermophilic digestions and kills currently on the market
The product of bacterium, and the packaging film of resistance to 140 DEG C of superhigh temperature cooking disinfections is considerably less because being limited by material and technique etc..
Summary of the invention
The technical problem that the one side of the disclosure solves, which is to provide one kind, has high combined strength bination and high barrier again
The packaging film of the new technology of resistance to 140 DEG C of superhigh temperature boilings.
To achieve the above object, the utility model adopts the following technical solution, and the utility model includes laminated polyester film,
The bottom of laminated polyester film is glued by the first glue-line and aluminum foil film layer, and the bottom of aluminum foil film layer passes through the second glue-line and Buddhist nun
Imperial film layer is glued, and the bottom of polyamide laminate film is glued by third glue-line and layer of polypropylene foil.
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, the polyamide laminate film is through upper and lower two-sided sided corona treatment.
Preferably, first glue-line, the second glue-line, third glue-line are identical or different adhesive layer.
The utility model compared with prior art, passes through the high combined strength bination adhesive clad aluminum foil film of laminated polyester film
Layer, then the polyamide laminate film of compound two-sided corona up and down, it is compound unidirectional by high combined strength bination adhesive again after cured reaction
The solidification of stretched polypropene film layer.This packaging film has high combined strength bination and high barrier resistance to 140 DEG C of superhigh temperature boilings again.
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- aluminum foil film layer, 3- polyamide laminate film, 4- simple tension polypropylene
Film layer, 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, superhigh temperature boiling packaging film, including biaxially oriented laminated polyester film 1, biaxially oriented laminated polyester film 1
Bottom it is glued with aluminum foil film layer 2 by the first glue-line 5, the bottom of aluminum foil film layer 2 by the second glue-line 6 with through double up and down
The polyamide laminate film 3 of face sided corona treatment is glued, and the bottom of polyamide laminate film 3 is thin by third glue-line 7 and simple tension polypropylene
Film layer 4 is glued, and the first glue-line 5, the second glue-line 6, third glue-line 7 are identical or different adhesive layer, the bonding of adhesive layer
Agent is polyurethane adhesives.
Specific processing flow are as follows: biaxially oriented laminated polyester film 1 is coated into binder through dry type compound working procedure and aluminium foil is thin
2 composite curing of film layer, dry type compound working procedure coat 3 composite curing of polyamide laminate film of binder and upper and lower two-sided corona again,
Dry type compound working procedure is coated with binder and 4 composite curing of simple tension layer of polypropylene foil.
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.
