Description
Technical field
The utility model relates to a kind of flexible packaging, particularly relates to a kind of packaging bag of two-layer encapsulation.
Background technology
Along with the quickening of modern life rhythm, people are more prone to special quality life.Prior art is used for sheathing foodstuff, liquid detergent, the wrapping various packaging bag of the daily lifes such as milk powder, usually be not easy to tear, if user wants to open packaging, just can only be cut off by scissors or tear by force, article in bag could be taken out, it is related to the comfort level that user uses product, and once open to again seal just more difficult, if even with great difficulty not cause the article in bag to make moist mildew and rot in sealing, should not pour out in bag during the substance migration made moist or lump, easily excessive, what have is not easy fast spread, dissolve, can not Reusability, waste very much not environmentally.
Summary of the invention
The purpose of this utility model is for the existing state of the art, provides a kind of packaging bag of two-layer encapsulation.
For achieving the above object, the utility model adopts following technical scheme:
A kind of packaging bag of two-layer encapsulation, mainly comprise: bag body, slide fastener and tear strips, described bag body forms primarily of at the bottom of bag face and bag, described bag face is made up of front and back two panels plastic sheeting heat-sealing bonding, bag face bottom margin and bag feather edge heat-sealing bonding, bag top, face is provided with sealing band, tear strips and slide fastener, and described tear strips is made up of the easy place of tearing and easy-torn line two parts, be positioned at easy-torn line correspondence both sides below sealing band or side be provided be convenient to bag face of tearing easily tear place.
Further, described slide fastener is made up of slider of zipper fastener and front slide rail sheet and aft ramp sheet three part, front slide rail sheet and aft ramp sheet by heat bonding in bag body interior.
Further, described front slide rail sheet is provided with groove, and slide rail sheet is provided with fin, and fin can be embedded in groove by slider of zipper fastener, and groove and fin are all provided with bound layer respectively.
Further, described slider of zipper fastener material is PVC, and slider of zipper fastener two sides have the anti-slip veins of strip.
In such scheme, described slide fastener and the distance of tear strips are 5mm ~ 25mm.
In such scheme, the left and right sides at the bottom of described bag and bottom margin bonding place, bag face adopt chamfer design.
The beneficial effects of the utility model are:
1, packaging bag top is provided with sealing band and the two-layer design of slide fastener, packaging bag does not carry out sealed package by means of only sealing band to its interior items or food, and after it is unlocked, slide fastener is utilized its bag of bodies top again to be encapsulated, in guarantee bag while article quality, its packaging bag of energy Reusability;
2, easily all design at packaging bag upper and lower side in the place of tearing compared to tradition, when tearing packaging bag, user cannot hold openings of sizes exactly, and opening may be caused excessive or too small.Easily the place of tearing coordinates easy-torn line to use, and be not only easy to open packaging bag, and opening can be torn along easy-torn line, fast very convenient;
3, bottom at the bottom of bag and bag face, edges at two ends bonding place adopts chamfer design, effectively can avoid less particle residue at the bottom of bag, cause unnecessary waste, and conveniently carries out secondary utilization to packaging bag.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the section-drawing of the utility model slide fastener;
Accompanying drawing 3 is the block diagram of the utility model slider of zipper fastener.
detailed description of the invention:
Can have the object of the utility model, feature and function to make juror and further understand, hereby lift preferred embodiment and coordinate graphic being described in detail as follows:
Refer to shown in Fig. 1 ~ 3, it is the schematic diagram of the preferred embodiment of the utility model, a kind of packaging bag of two-layer encapsulation, mainly comprise: bag body 1, slide fastener 2 and tear strips 3, described bag body 1 is primarily of 12 forming at the bottom of bag face 11 and bag, described bag face 11 is made up of front and back two panels plastic sheeting heat-sealing bonding, bag face 11 bottom margin and bag at the bottom of 12 edge heat-sealing bonding, at the bottom of its two panels oblong plastic sheeting and bag 12 form one can the cavity of storing articles, bag top, face 11 is provided with sealing band 4, tear strips 3 and slide fastener 2, distribute successively from top to bottom, its sealing band 4 is for last one package position of bag body 1.
Tear strips 3 in such scheme is by easily the place of tearing 31 and easy-torn line 32 two parts are formed, be positioned at the easy-torn line 32 below sealing band 4, its corresponding both sides of easy-torn line 32 or side be provided be convenient to tear bag face 11 easily tear place 31, tear along easy-torn line 32 from the easy place of tearing 31 always, fast very convenient, its easy-torn line 32 adopts the cutting of winding tension Systematical control break bar to form, and traditional electrical spark-over cost is high, effect is not ideal enough, and reject rate is higher.Described slide fastener 2 is made up of slider of zipper fastener 21 and front slide rail sheet 22 and aft ramp sheet 23 3 part, front slide rail sheet 22 and aft ramp sheet 23 are inner at bag body 1 by heat bonding, its front slide rail sheet 22 and aft ramp sheet 23 are symmetrically distributed on corresponding plastic sheeting, described front slide rail sheet 22 is provided with groove 221, slide rail sheet 23 is provided with fin 231, fin 231 can be embedded in groove 221 by slider of zipper fastener 21, its groove 221 and fin about 231 are respectively equipped with bound layer 5, and its bound layer 5 prevents groove 221 and fin 231 from departing from effectively.Described slider of zipper fastener 21 material is PVC, slider of zipper fastener 21 two sides have the anti-slip veins 211 of strip, effectively increase friction force, described slide fastener 2 is 5mm ~ 25mm with the distance of tear strips 3,12 left and right sides at the bottom of described bag and bottom margin bonding place, bag face 11 adopt chamfer design, avoid the corner of less particle residue at the bottom of bag.
When needing to use the article of bag body 1 inside, tearing along easy-torn line 32 from the easy place of tearing 31 always, then opening its bag of body 1 by slide fastener 2; When after the article using bag body 1 inside, fin 231 is embedded in groove 221 by slider of zipper fastener 21 by user, completes sealing; Again open bag body 1 if think, by slide fastener head 21, fin 231 is separated in groove 221, can Reusability its bag of body 1.
