Description
Technical field
This utility model relate to a kind of can the complex pocket torn of straight line.
Background technology
The thin film that the packaging bag of prior art is mostly plastic-aluminum combined is made, and to meet surface printing, light blocking blocks water
Requirement, consumer is when using the product of this packaging bags, and tearing port becomes irregular, frequently results in the article in sack
Accidentally spilling, especially in bag, article are the packaging of the products such as liquid particles shape, license Publication No. CN202038563U
Chinese patent discloses a kind of oriented tear packaging bag, and the hot strength being had by aluminium foil layer surface makes it produce ripple, this
Sample production cost is higher, and compound working procedure is many, and production efficiency is low.
Utility model content
The technical problems to be solved in the utility model be just to provide a kind of can the complex pocket torn of straight line, solve existing compound
The problem that bag production cost is high.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions: one can be torn by straight line
The complex pocket opened, including bag, bag is sequentially provided with hot sealing layer, adhesive layer and printing layer from the inside to the outside, and printing layer and heat-sealing
The thickness of layer ratio is for 1:7～1:8, and the thickness of printing layer and adhesive layer ratio is for 5:1～6:1, and hot sealing layer is polyethylene, and adhesive layer is
Adhesive for polyurethane, printing layer is polyester, and the inner side of printing layer is provided with printing layer, and bag is provided with easy-torn line or/and easily tear
Mouthful, printing layer is provided with and makes bag tear the ripple that mouth is linearly arranged.
Preferably, the thickness of adhesive layer is 1.7～2.5 μm, can select the thickness of adhesive layer according to different products
Selecting, then control printing layer and the thickness of hot sealing layer, beneficially printing layer are bonded in hot sealing layer, fastening effect is good, Practical Performance
Good.
In sum, advantage of the present utility model: 1. realize tearing of bag by easy-torn line or tearable mouth, and by holding
The print ripple that is provided with of layer makes bag tear mouth linearly to arrange, can effectively prevent the liquid in bag or particulate matter from spilling,
Can be widely used in light packaging, content is chocolate, confection or little granule packaging, and strong by the stretching of aluminium foil relative to existing
Degree makes bag easily tear, and has combination process simple, and processing cost is low, and the advantage that the use cost of raw material is low, can improve production
Efficiency；
2. printing layer is arranged on the inner side of printing layer, is avoided that the damage of printing layer；
3. the thickness ratio of printing layer with hot sealing layer is arranged to 1:7～1:8, according to different packing materials, bag can be carried out
Arranging, can improve Practical Performance, packaging bag body has excellent mechanical strength；
4. adhesive layer is arranged to adhesive for polyurethane, and the thickness of printing layer and adhesive layer is than for 5:1～6:1, can protect
Card hot sealing layer and the bond properties of printing layer, prevent coming off of printing layer；
5. printing layer being set to polyester, polyester itself has excellent printing performance, it is simple to printing layer printing, and polyester
There is transparency good, it is simple to printing layer is observed, and surface of polyester gloss and have good mechanical performance, deflection is good, it is simple to ripple
Generate.
Accompanying drawing explanation
The utility model is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is that this utility model is a kind of can the structural representation of complex pocket torn of straight line；
Fig. 2 is the structural representation of this utility model bag.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of can the complex pocket torn of straight line, including bag 1, bag 1 is sequentially provided with from the inside to the outside
Hot sealing layer 2, adhesive layer 3 and printing layer 4, hot sealing layer 2 is polyethylene, and adhesive layer 3 is adhesive for polyurethane, and printing layer 4 is polyester,
And the inner side of printing layer 4 is provided with printing layer 5, bag 1 is provided with easy-torn line 6 and tearable mouth 7, and easy-torn line 6 is arranged on tearable mouth 7
Lower section, can improve the sealing property of bag, and printing layer 4 is provided with and makes bag 1 tear the ripple 8 that mouth is linearly arranged, adhesive layer 3
Thickness be 2 μm, the thickness of printing layer 4 is 12 μm, and the thickness of adhesive layer 3 is 70 μm, can be according to different products to adhesive layer
Thickness select, then control printing layer and the thickness of hot sealing layer, beneficially printing layer and be bonded in hot sealing layer, fastening effect
Good, Practical Performance is good.
During generation, first the Surface Machining at printing layer 4 forms ripple 8, and the printing layer 4 that inner side is coated with printing layer 5 leads to
Crossing adhesive for polyurethane to be compounded on hot sealing layer 2, then at a temperature of 45 DEG C, ripening forms composite membrane, then according to life in 72 hours
Composite membrane is cut by one-tenth demand, bag processes, and processes easy-torn line 6 or and tearable mouth 7 on bag 1.
In addition to above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can be according to this
Invention is variously modified and deforms, and without departing from spirit of the present utility model, all should belong to right appended by this utility model
Require defined scope.
