Abstract
The utility model provides a kind of vacuum diaphragm, its structure setting is five layers, including polyethylene layer, nylon layer, bonded between the polyethylene layer and the nylon layer by resin adhesive layer, the another side of the nylon layer is bonded by resin adhesive layer and polyethylene layer, the thickness of the nylon layer is set to 0.010 0.014mm, and the thickness of the polyethylene layer is set to 0.012 0.016 ㎜, and the thickness of the resin adhesive layer is set to 0.010 0.012mm.The utility model structure design is simple, and pliability is good, high-barrier.
Description
Technical field
It the utility model is related to a kind of packaging film, and in particular to a kind of vacuum diaphragm.
Background technology
With the adjustment of expanding economy, Chinese all trades and professions constantly rise to the market demand of plastic sheeting.China's modeling
Material film industry is in a booming stage, it is reported that, the demand of Chinese Plastics film is every year by with more than 9%
Speed increases.And as various new materials, new equipment and new technology are constantly emerged in large numbers, will promote China plastic sheeting towards
Diversification of varieties, customizations and possess multi-functional composite membrane direction and develop.Conventional plastic sheeting has polyethylene（PE）, it is poly-
Vinyl chloride（PVC）, polystyrene (PS), polyester film（PET）, polypropylene（PP）, nylon etc..Various performance of plastic film are not
Together, the complexity of printing is also different, and the purposes as packaging material is also different.Polyethylene film is a kind of colourless, tasteless, nothing
Smelly, translucent avirulent insulating materials, largely as packaging bag；Food bag, various containers can be also made, but it is inertia
Material, so more difficult printing, it is necessary to after processing, can just print off relatively good effect.The intensity of nylon film compares polyethylene
Film is big, tasteless, nontoxic, impermeable bacterium, oil resistant, resistance to ester, resistance to boiling water and most of solvent, is generally used for loading, wear-resisting bag
Dress, but its water imbibition is big, influences the compact dimensions of film.In view of the foregoing, the utility model provides a kind of structure design letter
Single, pliability is good, high-barrier, is not easy the vacuum diaphragm of delamination.
Utility model content
A kind of structure design of the utility model offer is simple, and pliability is good, high-barrier, is not easy the vacuum diaphragm of delamination.
In order to solve above-mentioned technical proposal, the utility model adopts the following technical scheme that：
A kind of vacuum diaphragm, its structure setting is five layers, including polyethylene layer, nylon layer, the polyethylene layer and the Buddhist nun
Bonded between imperial layer by resin adhesive layer, the another side of the nylon layer is bonded by resin adhesive layer and polyethylene layer.
A kind of vacuum diaphragm provided by the utility model, the thickness that can be further arranged to the nylon layer are less than described gather
Pvdf layer.
A kind of vacuum diaphragm provided by the utility model, the thickness that can be further arranged to the nylon layer are set to 0.010-
0.014mm, the thickness of the polyethylene layer are set to 0.012-0.016 ㎜, and the thickness of the resin adhesive layer is set to 0.010-
0.012mm。
A kind of vacuum diaphragm provided by the utility model, it is viscous using EVA modifications that the resin adhesive layer can be further arranged to
Resin or LLDPE binder resins.
To sum up, a kind of vacuum diaphragm provided by the utility model, there is five-layer structure, and polyethylene layer is glued by two layers of resin glue-line
The two sides of nylon layer is attached to, design structure is simple, simplifies film production process, and barrier property is preferable, by setting poly- second
The pliability of the thickness lifting vacuum diaphragm of alkene layer, nylon layer and resin adhesive layer, while reduce production cost.
Brief description of the drawings
Preferred embodiment of the present utility model is carried out below in conjunction with the accompanying drawings to describe in detail or preferably, wherein,
Fig. 1 is a kind of schematic diagram of vacuum diaphragm of the utility model；
Wherein：1. the resin adhesive layer of 2. nylon layer of polyethylene layer 3..
Embodiment
Refer to the attached drawing 1 is described further to a kind of embodiment of vacuum diaphragm of the utility model：
Structure setting of the present utility model is five layers, including polyethylene layer 1, nylon layer 2, the polyethylene layer 1 with it is described
Being bonded between nylon layer 2 by resin adhesive layer 3, the another side of the nylon layer 2 is bonded by resin adhesive layer 3 and polyethylene layer,
Design structure is simple, simplifies film production process, and barrier property is preferable.
The thickness of the nylon layer 2 is less than the polyethylene layer 1, avoids nylon layer from absorbing excessive moisture and be layered
The phenomenon of stripping.
The thickness of the nylon layer 2 is set to 0.010-0.014mm, and the thickness of the polyethylene layer 1 is set to 0.012-0.016
㎜, the thickness of the resin adhesive layer 3 are set to 0.010-0.012mm, by setting polyethylene layer 1, nylon layer 2 and resin adhesive layer
The pliability of 3 thickness lifting vacuum diaphragm, while reduce production cost.
The resin adhesive layer 3 is modified binder resin or LLDPE binder resins using EVA.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Progress equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc.,
It should be included within the scope of protection of the utility model.
