Abstract
It the utility model is related to composite packaging co-extrusion technical field of membrane, a kind of air column bag five-layer co-squeezing film is provided, it is made it is characterized in that extruding melting blown film using coextrusion mold machine, including being made up of LDPE, MDPE, PP, PA and binding agent, wherein first layer is that LDPE, MDPE and PP are mixed, the second layer and the 4th layer are adhesive layer, and third layer is PA layers, and layer 5 is that LDPE and MDPE is mixed.Air column bag of the present utility model can be widely used for air column bag production with the characteristic such as there is five-layer co-squeezing film simple in construction, surface easily to print, thickness evenness is good, intensity is high, tear resistance is good.
Description
Technical field
Composite packaging co-extrusion technical field of membrane is the utility model is related to, is a kind of air column bag five-layer co-squeezing specifically
Film.
Background technology
Air column bag also known as buffers air column bag, is to be filled with natural air, be widely used in the new of product packaging transport
Packaging system, there is the characteristic such as inexpensive, recyclable, pollution-free, easy to use.
Existing air column bag is process with materials such as film generally use PE, EVOH, PA through melt-out spinning technique, heat seal
Easily there is fold, bubble, surface is not easy printing and uneven film thickness is even, and local strength is poor, it is impossible to bears higher inflation pressure
Power, cause air column bag gas column rupture to occur in use or the problems such as gas leakage, packaging product is impacted.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of air column bag five-layer co-squeezing
The technical scheme of film.
A kind of air column bag five-layer co-squeezing film, it is characterised in that melting blown film is extruded using coextrusion mold machine and is made, is wrapped
Include and be made up of LDPE, MDPE, PP, PA and binding agent, wherein first layer is the first PE layers, is mixed by LDPE, MDPE and PP,
The second layer and the 4th layer are adhesive layer, and third layer is PA layers, and layer 5 is the 2nd PE layers, by LDPE and MDPE mixing
Into.
As it is of the present utility model it is a kind of improve, the air column bag with LDPE, MDPE of five-layer co-squeezing film first layer and
PP ratios are 1:1：0.5~1:1：1.
As a kind of improvement of the present utility model, the air column bag five-layer co-squeezing film second layer and the 4th layer of material one
Sample, mixed for domestic LLDPE and imported L LDPE.
As it is of the present utility model it is a kind of improve, the air column bag with the PA materials of five-layer co-squeezing film third layer be PA6,
PA66 and PA11 one or more.
As a kind of improvement of the present utility model, LDPE the and MDPE ratios of air column bag five-layer co-squeezing film layer 5
Example is 1:1~1:1.2.
As a kind of improvement of the present utility model, the air column bag five-layer co-squeezing film thickness is 50~100 μm.
A kind of above-mentioned air column bag five-layer co-squeezing film, have simple in construction, surface is easily printed, thickness evenness is good,
The characteristics such as intensity is high, tear resistance is good, it can be widely used for air column bag production；First layer adds PP raw materials, can form surface light
Pet layer that is sliding, easily printing, same material difference unsymmetric structure is used with layer 5, is reduced the electrostatic effect between film, is bonded
Power, production efficiency is improved, while reduce the fold easily occurred during heat seal, bubble phenomenon.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model air column bag five-layer co-squeezing film.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：A kind of as shown in figure 1, gas column
Bag uses five-layer co-squeezing film, and extruding melting blown film using coextrusion mold machine is made, including by LDPE, MDPE, PP, PA and binding agent
Composition, wherein first layer A is the first PE layers, is 1 in proportion by LDPE, MDPE and PP:1:0.5~1:1：1 mixes；Second
B and the 4th layer of D of layer is adhesive layer, and material is that domestic LLDPE and imported L LDPE is mixed；Third layer C is PA layers, material
Matter is PA6, PA66 and PA11 one or more；Layer 5 E is the 2nd PE layers, is 1 in proportion by LDPE and MDPE：1~1：
1.2 mix；The five-layer co-squeezing film thickness is 50~100 μm.
Shown in described above and figure be only preferred embodiment of the present utility model, one of ordinary skill in the art's energy
All deformations for directly exporting or associating from the utility model disclosure, are considered as protection of the present utility model
Scope.
