Abstract
The utility model discloses a reticulation vacuum bag belongs to plastics vacuum packaging field, comprises two bag body membranes, and every bag body membrane is two -layer structure, the level and smooth membrane of lower floor and the unsmooth membrane on upper strata. Unsmooth membrane includes lug and recess, and the lug is positive prismatic table structure, and each lug evenly distributed forms the recess each other, lug surface design " ten " word two crossing channels, the cross -section of channel is semi -circular, and the channel is located the lateral wall and the mesa of positive terrace with edge lug. The utility model discloses change traditional vacuum packaging pouch's ordinary plastic film structure, adopt the protruding structure of reticulation to at bulge design channel, thoroughly solve the not thorough problem of vacuum bag evacuation.
Description
Technical field
This utility model belongs to plastic vacuum packing technique field, is related to vacuum bag, especially a kind of reticulate pattern vacuum bag.
Background technology
Vacuum packaging is also referred to as decompression packaging, is to be completely drawn out sealing by the air in packing container, maintains in bag and be in height
Degree decompression state, air starvation is equivalent to hypoxia effect, makes microorganism not have conditions of existence, to reach fresh, the anosis corruption of fruit
The purpose occurring.Vacuum packaging bag is used for packaging for foodstuff, can effectively extend the shelf-life of food.In edible vacuum packaging
Bag in food when it is possible to once food cannot be used up needs continue storage when be inconvenient to pack because sack is opened
Seal up for safekeeping, particularly in the wild edible food when, the food eaten up it is possible to can cause waste.
Traditional vacuum packaging bag adopts the sack that common plasticses diaphragm is formed, and inner surface is bright finish, in evacuation, with
The extraction of air, under the influence of air pressure, bag inner surface is fitted, intercept thus path being extracted out to air in sack and being formed,
Impact vacuumizing effect.For problem present in this use, the plastic foil that vacuum bag is used improves, in vacuum bag
Plastic foil inner surface extrude groove and the protruding block that is separated out through groove；So in vacuum, even if in vacuum bag
Fit in surface, protruding block forms and supports, and groove provides the path that air is extracted out, it is to avoid laminating space-time gas circuit in surface in conventional bag body
The problem that footpath is blocked, improves vacuumizing effect.Even so, but because bulge-structure is identical, bossing easily occurs
Dock extruding phenomenon with groove part so that the evacuation of vacuum bag is not thorough.
Utility model content
This utility model is to solve the deficiencies in the prior art, provides a kind of reticulate pattern vacuum bag, changes traditional vacuum packaging bag
Common plasticses diaphragm structure, using reticulate pattern bulge-structure, and bossing design raceway groove, thoroughly solve bag vacuum
Not thorough problem.
The technical solution of the utility model is as follows：
A kind of reticulate pattern vacuum bag, is made up of two panels bag film, and every bag film is double-layer structure, the flatted membrane of lower floor and upper
The embossed film of layer.
Embossed film includes projection and groove, projection be positive terrace with edge structure, each projection be uniformly distributed formed each other recessed
Groove.Groove is distributed in the vertical direction of projection bottom periphery, and embossed film is divided into reticulate structure by the first groove and the second groove.
Due to the supporting role of projection, when the vacuum bag of bag film composition is evacuated, can be formed certain between projection and groove
Exhaust passage, improve the efficiency of evacuation and vacuum.
Due to small volume, the elastic big, changeableness of projection, in vacuum, for avoiding projection to be subject to air buckling
Stretch into after shape in groove and exhaust passage is blocked, design raceway groove on the surface of projection.
Further, each lug surface designs two raceway grooves that " ten " word intersects, and the section of raceway groove is semicircle, raceway groove
On the side wall and table top of positive terrace with edge projection.
Further, channels cross-section semicircle radius is 0.5mm, because circular configuration non-deformability is strong, when vacuum bag is taken out
Raceway groove will not be caused to deform under projection atmospheric pressure effect during vacuum, the moment being easy to exhaust passage is unimpeded.
Further, bag film be co-extrusion film, all layers of co-extrusion film are all in the extrusion molding simultaneously of same time, layer with
It is without adhesive between layer by hot melt combination, therefore relatively reliable to the wholesomeness of packaging for foodstuff co-extrusion film,
There is more preferable tensile property.
Effect of the present utility model and benefit are：
(1) this reticulate pattern vacuum bag, changes the common plasticses diaphragm structure of traditional vacuum packaging bag, using the raised knot of reticulate pattern
Structure, and design raceway groove in bossing, thoroughly solve the not thorough problem of bag vacuum；
(2) structure simple it is easy to manufacture, easy to use, improve the efficiency of evacuation of vacuum bag and vacuum bag
Vacuum.
Brief description

Fig. 2 bag film cross-sectional view.
In figure：1 projection；2 grooves；3 flatted membranes；4 embossed film；11 raceway grooves；21 first grooves；22 second grooves.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
A kind of reticulate pattern vacuum bag, as shown in Figure of description 1 and Figure of description 2, is made up of two panels bag film, every bag
Body film is double-layer structure, the flatted membrane 3 of lower floor and the embossed film 4 on upper strata.Embossed film 4 includes projection 1 and groove 2, and projection 1 is just
Terrace with edge structure, each projection is uniformly distributed formation groove 2 each other.Groove 2 includes the first groove 21 and the second groove 22, point
In the vertical direction of convex 1 bottom periphery, embossed film 4 is divided into reticulate structure to cloth by the first groove 21 and the second groove 22.
When vacuum bag is evacuated, due to the supporting role of projection 1, can be formed certain between projection 1 and groove 2
Exhaust passage, improves efficiency and the vacuum of evacuation.For avoiding projection 1 to be subject to after air compressive strain to stretch into aerofluxuss in groove 2
Channel blockage, designs raceway groove 11 on the surface of projection.
Two raceway grooves 11 that " ten " word intersects are designed on each projection 1 surface, and the section of raceway groove 11 is semicircle, raceway groove 11
On the side wall and table top of positive terrace with edge projection 1.Raceway groove 11 section semicircle radius is 0.5mm, due to circular configuration resistance to deformation
Ability is strong, raceway groove 11 will not be caused when bag vacuum to deform under the effect of projection atmospheric pressure, be easy to exhaust passage when
Carve unimpeded.
Bag film is co-extrusion film, and all layers of co-extrusion film are all in the extrusion molding simultaneously of same time, between layers
It is without adhesive by hot melt combination, therefore relatively reliable to the wholesomeness of packaging for foodstuff co-extrusion film, it may have more
Good tensile property.
Embodiment described above is only embodiment of the present utility model to be described, not to this utility model
Spirit and scope be defined.On the premise of without departing from this utility model design concept, this area ordinary person is to this reality
The various modifications made with new technical scheme and improvement, all should drop into protection domain of the present utility model, and this practicality is new
The scope of type is limited by claims rather than described above.
