Abstract
The utility model discloses a kind of dilated food packaging film of ultra-low temperature heat sealing, and the dilated food packaging film is made of Biaxially oriented polypropylene delustring film layer and vacuum aluminum-coated layer of polypropylene foil, compound by polyurethane glue.The dilated food packaging film of the ultra-low temperature heat sealing of the utility model has the advantage that (1) structure is relatively simple, and flat appearance is good, and heat-seal operation can be completed under low-temperature condition；(2) tensile strength height is had both using Biaxially oriented polypropylene matt film, barrier property is good, the high advantage of transparency；(3) have many advantages, such as beautiful gloss, outstanding shading performance, good oxygen barrier and water preventing ability, outstanding aluminium layer adhesive force and low heat-sealing temperature and high heat-sealing strength using vacuum aluminum-coated layer of polypropylene foil.
Description
Technical field
The utility model relates to packaging material manufacture fields, and in particular to a kind of dilated food packaging of ultra-low temperature heat sealing
Film.
Background technique
Currently, plastic packaging film is widely used among daily life every field, output film has good resistance
Separating performance has high economic value.Thickness can occur not in cutting because of manufacture craft problem in some packaging film productions
Uniform situation.
Utility application number is that one kind three is proposed in 201220427258.6 disclosed on 03 13rd, 2013
Layer co-extruding biaxial stretched polypropylene film of aluminizing, the film have among trilamellar membrane structure, including polypropylene top layer, polypropylene
Layer, polypropylene backing layer and aluminium coated, solve the problems, such as that heat-sealing temperature is high, but it is compound be more troublesome, cost of manufacture is also higher.
Utility model content
The purpose of this utility model is to provide a kind of dilated food packaging film of ultra-low temperature heat sealing, which is fabricated to
This is cheap, compound to be easy.
Technical solution used by the utility model is a kind of dilated food packaging film of ultra-low temperature heat sealing, the packaging film
It is stacked gradually by Biaxially oriented polypropylene delustring film layer, adhesive layer and vacuum aluminum-coated layer of polypropylene foil, it is described two-way
Oriented polypropylene delustring film layer and vacuum aluminum-coated layer of polypropylene foil are bonded by adhesive layer to be laminated；
Biaxially oriented polypropylene delustring film layer with a thickness of 18-25 microns；
Vacuum aluminum-coated layer of polypropylene foil with a thickness of 25-35 microns.
Biaxially oriented polypropylene matt film has both tensile strength height, and barrier property is good, the high advantage of transparency.
Biaxially oriented polypropylene delustring film layer with a thickness of 18-25 microns, this thickness moisture-proof characteristic is superior, particularly suitable
In food packagings such as biscuit, the dessert of the easy moisture absorption.
Vacuum aluminum-coated layer of polypropylene foil with a thickness of 25-35 microns, 25-35 microns of thickness makes vacuum aluminum-coated poly- third
Alkene film layer has beautiful metal luster, excellent gas and light barrier property and good moisture-proof, shading, alternative
Aluminium foil etc. uses.Heat sealability is excellent, can low-temperature heat-sealing, aluminium layer adhesive force is good, is not in that aluminium layer transfer layering is existing after compound
As.
Preferably, the adhesive layer is polyurethane adhesive water layer.The polyurethane adhesive water layer has excellent anti-shearing strong
Degree, performance is more than other kinds of adhesive layer at low and ultra-low temperatures.
Compared with prior art, the utility model have it is following the utility model has the advantages that
The dilated food packaging film of the ultra-low temperature heat sealing of the utility model has the advantage that
(1) structure is simple, and production only needs simple polyurethane glue-line compound, and it is in uneven thickness to solve part packaging film
Problem also reduces the cost of manufacture of finished product, has good flat appearance and barrier property, while can be complete under low-temperature condition
At heat-seal operation.
(2) tensile strength height is had both using Biaxially oriented polypropylene matt film, barrier property is good, the high advantage of transparency.
(3) there is beautiful gloss, outstanding shading performance, good oxygen barrier using vacuum aluminum-coated layer of polypropylene foil and blocks water
The advantages that property, outstanding aluminium layer adhesive force and low heat-sealing temperature and high heat-sealing strength.
Detailed description of the invention
Fig. 1 is that the three-layer co-extruded biaxial tension of the prior art is aluminized the film layer structure schematic diagram of polypropylene film；
Fig. 2 is the film layer structure schematic diagram of the dilated food packaging film of the utility model ultra-low temperature heat sealing；
In figure:
1, Biaxially oriented polypropylene delustring film layer 2, vacuum aluminum-coated layer of polypropylene foil
3, polypropylene top layer 4, polypropylene middle layer
5, polypropylene backing layer 6, aluminium coated
Specific embodiment
As shown in Figure 1, aluminizing polypropylene film, including polypropylene top for a kind of three-layer co-extruded biaxial tension in the prior art
Layer 3, polypropylene middle layer 4, polypropylene backing layer 5 and aluminium coated 6.
As shown in Fig. 2, a kind of dilated food packaging film of ultra-low temperature heat sealing of the utility model, by Biaxially oriented polypropylene
Delustring film layer 1 and vacuum aluminum-coated layer of polypropylene foil 2 are laminated, and two film layers are bonded by polyurethane adhesive water layer (not shown)
Composite laminate.
The prior art is compared, the structure of the utility model has a degree of optimization, and it is compound to be easy, solve part packaging
The even problem of non-uniform film thickness also reduces the cost of manufacture of finished product, with good flat appearance and barrier property, while
Heat-seal operation can be completed under low-temperature condition.
In addition, having both tensile strength height using Biaxially oriented polypropylene matt film, barrier property is good, high excellent of transparency
Point.There is beautiful gloss, outstanding shading performance, good oxygen barrier and water preventing ability, outstanding using vacuum aluminum-coated layer of polypropylene foil
The advantages that aluminium layer adhesive force and low heat-sealing temperature and high heat-sealing strength.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
