Abstract

A kind of sealing bags of easily openable, include inner liner, intermediate layer and outer lining successively from inside to outside, the hermetic bag both ends are finalization area, and the outer lining includes at least one Weak link domain, and the Weak link domain is the band around packaging bag.In the technical solution of the utility model, by the way of Weak link domain is set on outer lining, weak bonding pad as packaging bag, consumer can be made to be easy to from there tear packaging bag, avoid the existing accidental injury of common tearable mouth design, tear risk by mistake, and point off formula line of weakness sealing effectiveness it is bad the problem of, be not only easy to tear off, and preparation technology is simple.

Description

A kind of sealing bags of easily openable

Technical field

The present invention relates to a kind of packaging bag, especially a kind of hermetic bag of easily openable, belong to packaging bag technical field.

Background technology

With the continual and steady development of China's economic and the increasingly raising of living standards of the people, requirement of the people to food is got over Come higher.In order to improve the circulation cycle of food and shelf life, the effect of packaging for foodstuff becomes more and more important.For packaging for foodstuff Material requirements serves the effect of guarantee the quality, be fresh-keeping, protecting flavor to food, and moreover, the packaging bag for packaging for foodstuff needs There are good sealing, and the use of consumer for convenience, be usually provided with tearable mouth.

In the prior art, the setting of packaging bag one end is typically employed in easily to tear breach, set and easily tear zipper tape or in packaging bag One end set-point segmentation line of weakness, facilitates the tearing off packaging bag.But the set-up mode of these tearable mouths, easily tear breach and wedge angle be present, Easily accidentally injure children, point segmentation line of weakness has the problem of sealing effectiveness is bad, sets the easy zipper tape that tears cost height, system to be present The problems such as standby process complexity.

Utility model content

For deficiency of the prior art, the utility model provides a kind of easily openable sealing bags, simple in construction, uses It is convenient.The technical solution adopted in the utility model is as follows：

A kind of sealing bags of easily openable, include inner liner, intermediate layer and outer lining, the sealing successively from inside to outside Bag both ends are finalization area, and the outer lining includes at least one Weak link domain, and the Weak link domain is the band around packaging bag.

Easily openable sealing bags described in the utility model, it is preferable that the outer lining is pet layer, except Weak link domain Outer outer liner layer thickness is 15~30 μm.

Easily openable sealing bags described in the utility model, it is preferable that the thickness of outer lining is 0 on the Weak link domain ~5 μm.Weak bonding pad of the Weak link domain as sealing bags, can make consumer be easy to from there tear packaging bag.

Easily openable sealing bags described in the utility model, it is preferable that the Weak link domain is that outer liner layer thickness is 0 Complete fracture belt.

Easily openable sealing bags described in the utility model, it is preferable that the width in the Weak link domain is 2~3mm.

Easily openable sealing bags described in the utility model, it is preferable that the Weak link domain is one.

Easily openable sealing bags described in the utility model, it is preferable that the Weak link domain is the ring-type band of closing.

Easily openable sealing bags described in the utility model, it is preferable that the Weak link domain is the ring non-fully closed Shape band, the ring-type bar non-fully closed take the connector for 0.5~2cm provided with length, are thick at the connector Spend the outer lining for 15~30 μm.Such design makes the tearing notch of packaging bag form ring-type jaggy, can make the portion torn Divide and be not easy to separate with packaging bag main body, beneficial to environmental protection.

Easily openable sealing bags described in the utility model, it is preferable that the inner liner (101) is food-grade polyethylene Layer or food-grade polypropylene layer (i.e. PE or PP layers), thickness are 5~10 μm；The intermediate layer is aluminium foil layer.

Easily openable sealing bags described in the utility model, it is preferable that sealed using hot melting way the finalization area.

In the technical solution of the utility model, by the way of Weak link domain is set on outer lining, as packaging bag Weak bonding pad, consumer can be made to be easy to from there tear packaging bag, avoided present in common tearable mouth design Accidentally injure, tear risk by mistake, and the problem of point off formula line of weakness sealing effectiveness is bad, be not only easy to tear off, and preparation technology is simple, Consumer can also determine the size of tearing notch according to self-demand；And to be the ring-type band non-fully closed set in Weak link domain Meter, the part that can avoid tearing separates with packaging bag main body, avoid consumer's environmental consciousness it is not strong when the part that will tear Throw out without care, unnecessary refuse disposal problem is caused, beneficial to environmental protection.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe.

Embodiment 1

The sealing bags of easily openable, as shown in figure 1, it includes inner liner 101, the and of intermediate layer 102 successively from inside to outside Outer lining 103, the hermetic bag both ends are finalization area 200, and the outer lining includes a Weak link domain 300.The Weak link Domain 300 is the band around packaging bag.Outer lining 103 is pet layer, and thickness is 20 μm；Weak link domain 300 is around packaging bag Parallel to the closed circular band of finalization area, width 2mm, it is the complete fracture belt of no outer lining.The inner liner 101 For food-grade polyethylene layer, thickness is 8 μm, and the intermediate layer is aluminium foil layer, and finalization area is sealed using hot melting way.

Embodiment 2

The sealing bags of easily openable, as shown in Fig. 2 it includes inner liner 101, the and of intermediate layer 102 successively from inside to outside Outer lining 103, the hermetic bag both ends are finalization area 200, and the outer lining includes a Weak link domain 300.The Weak link Domain 300 is the band around packaging bag.Outer lining 103 is pet layer, and thickness is 25 μm；The width of Weak link domain 300 is 2mm, and it is There is no the complete fracture belt of outer lining.Weak link domain 300 is the non-fully closed circular parallel to finalization area around packaging bag Band, which is provided with the connector 400 that length is 1cm, is the outer lining that thickness is 25 μm at the connector 400, can make The part that kind of packaging sealing package is torn does not separate with main body.The inner liner 101 is food-grade polypropylene layer, and thickness is 10 μm, institute It is aluminium foil layer to state intermediate layer, and finalization area is sealed using hot melting way.
