Abstract
The present invention discloses a kind of puncture resistance composite membrane, it is characterized by: the composite membrane is three-decker, it is from top to bottom followed successively by first layer (1), the second layer (2) and third layer (3), wherein first layer (1) and third layer (3) are all made of density in 0.93g/cm3Above PE material is made, and the second layer (2) is then using density in 0.9g/cm3PE material below is made, and first layer (1) is equal with the thickness of the second layer (3), and the thickness ratio between first layer (1) and the second layer (2) is 1:2, and above-mentioned three layers are prepared into composite membrane using multi-layer co-extruded technique.
Description
Technical field
The present invention relates to the production field of plastic film, especially a kind of puncture resistance composite membrane.
Background technique
The application range of composite membrane is very extensive, especially with the composite membrane that PE is prepared as raw material, is eating
Product, medical treatment and industrial aspect have extremely wide application.When being packaged in pack content made of composite membrane, if by wrapping
There are spine, corner angle etc. on the article of dress, then are very easy to puncture packaging bag, such as packaging dried sea-cucumber, packaging screw etc.
When product, above situation is frequently encountered.Therefore a kind of method or apparatus for being able to solve the above problem is needed now.
Summary of the invention
The present invention is to propose that a kind of puncture resistance is preferable to solve above-mentioned deficiency present in the prior art, it is not easy to
The composite membrane being punctured.
The technical solution of the invention is as follows: a kind of puncture resistance composite membrane, it is characterised in that: the composite membrane is
Three-decker is from top to bottom followed successively by first layer 1, the second layer 2 and third layer 3, and wherein first layer 1 and third layer 3 are all made of close
Degree is in 0.93g/cm3Above PE material is made, and the second layer 2 is then using density in 0.9g/cm3PE material below is made, and
And first layer 1 is equal with the thickness of the second layer 3, and the thickness ratio between first layer 1 and the second layer 2 is 1:2, above-mentioned three layers of use
Multi-layer co-extruded technique is prepared into composite membrane.
The present invention compared with the existing technology, has the advantages that
The puncture resistance composite membrane of this kind of structure type is prepared by three layers of PE film using multi-layer co-extruded technique, outside
Two layers of side is all made of the relatively hard PE material of material, and internal layer (middle layer) the then PE material relatively soft using material,
Twice with a thickness of other two layers of thickness of middle layer softer simultaneously, this special structure of composite membrane lead to sharppointed article
It needs bigger strength that could simultaneously puncture three-decker, falls in packaging bag from eminence or in the case where mutual extrusion, still
So can effective protection packaging bag will not be punctured.And the preparation process of this composite membrane is simple, and manufacturing cost is cheap, therefore
It may be said that it has a variety of advantages, particularly suitable for promoting and applying in the art, market prospects are very wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific embodiment
Below in conjunction with Detailed description of the invention a specific embodiment of the invention.A kind of puncture resistance is compound as shown in Figure 1:
Film, the composite membrane are three-decker, are from top to bottom followed successively by first layer 1, the second layer 2 and third layer 3, wherein first layer 1 and the
Density is all made of in 0.93g/cm for three layer 33Above PE material is made, and the second layer 2 is then using density in 0.9g/cm3It is below
PE material is made, and first layer 1 is equal with the thickness of the second layer 3, while the thickness ratio between first layer 1 and the second layer 2 is
1:2, above-mentioned three layers are prepared into composite membrane using multi-layer co-extruded technique.
The puncture resistance composite membrane of the embodiment of the present invention is prepared by three layers of PE film using multi-layer co-extruded technique,
It is all made of the relatively hard PE material of material for two layers on the outside of it, and internal layer (middle layer) the then PE material relatively soft using material
Material, while twice with a thickness of other two layers of thickness of softer middle layer, this special structure of composite membrane lead to sharp object
Product need bigger strength that could simultaneously puncture three-decker, fall in packaging bag from eminence or in the case where mutual extrusion,
Still being able to effective protection packaging bag will not be punctured.
Claims (1)
1. a kind of puncture resistance composite membrane, it is characterised in that: the composite membrane is three-decker, is from top to bottom followed successively by the
One layer (1), the second layer (2) and third layer (3), wherein first layer (1) and third layer (3) are all made of density in 0.93g/cm3With
On PE material be made, and the second layer (2) then using density in 0.9g/cm3PE material below is made, and first layer (1)
It is equal with the thickness of the second layer (3), and the thickness ratio between first layer (1) and the second layer (2) is 1:2, above-mentioned three layers using more
Layer coextrusion processes are prepared into composite membrane.
