Abstract
The utility model discloses a self-support packaging bag. The bag comprises a bag body, a bag port disposed at the upper end of the bag body, and a bag bottom. The bag body comprises an outer bag body unit and at least an inner packaging layer disposed inside the outer bag body unit. The edge of the bag bottom is in heat sealing pressure connection with the lower edge of the outer bag body unit to form an outer packaging layer. Chambers are disposed between the outer packaging layer and the inner packaging layer, and between an inner packaging layer and an adjacent packaging layer. The chambers are in the shape of a vase and other curve shapes with low center of gravity. The outer packaging layer and the inner packaging layer are connected at the bag port. The packaging bag is provided with the bag bottom and the special curve shape of the inner and the outer packaging layers to ensure objects in the bag to be more stably positioned in the self-support manner under the effects of self-weight. The inner packaging layer, the outer packaging layer and the chambers between the inner and the outer packaging layers have buffer functions to some extent, tensile strength and tearing intensity are improved, and wear resistance and sealing are enhanced.
Description
Technical field

In daily life, because flexible packaging cost is low and easy to use, be therefore subject to people's favor, use flexible packaging to become a kind of development tendency of packing technique to fixed class and liquid type commodity.But use flexible packaging to have following defect: after the packed article of existing flexible packaging, not conventionally to be able to support oneself, while depositing, be easy to trickle down, and this soft packaging bag is generally square monolayer package bag, its tensile strength and peel strength are poor, resistance to abrasion and gas barrier properties are low, easily break and reveal the commodity in packaging bag after wipe contact, and profile is not attractive in appearance in addition, cannot attract client's eyeball, can not change the desire to purchase of client to common soft packaging bag.
Along with the continuous progress of packing technique, Self-support packing bag becomes a kind of packaged form all the fashion at present, it has good counter display effect, can easily carry and very easy to use, Chinese invention patent Granted publication CN102494375 discloses a kind of self-support soft packaging bag with mouth suitable for reading, it mainly comprises a bag body, the sealing with it of the bag end and bag, bag body is made up of two of front and back, the two bag bodies in front and back, the surrounding hot-pressing, edge-sealing sealing of the bag end and bag sealing with it, the upper angle of the two bag bodies in front and back is set as to corner cut, corresponding four corner cuts are cut at corresponding four angles of also bag being sealed with it, the hexagon of bag sealing is with it corresponding with bag body, two of front and back each three limit hot-pressing, edge-sealings sealings respectively, between sealing, seal a discharging gate is housed with it in bag body anter top and bag, the utility model is provided with bag bottom structure, can make to pack packed the self-support of article bag body places, but, no matter bag body or a bag end, are still single bag body structure, certainly exist the above-mentioned defect that monolayer package bag has.
Utility model content
There is common square single bag body structure in order to overcome existing Self-support packing bag, its tensile strength and peel strength are low, the defects such as resistance to abrasion and gas barrier property are poor, the purpose of this utility model is to provide a kind of special-shaped Self-support packing bag, this abnormity Self-support packing bag has the Bag structure and the lower particular curve profile of center of gravity that are made up of external packing layer and at least one inner packing layer, pack the placement of not only can supporting oneself after article into reliable and stablely, and can more effectively improve the lubricity of bag, resistance to abrasion and gas barrier property, strengthen tensile strength and peel strength, simultaneously, cavity between exterior and interior packing layer can effectively cushion due to extraneous squeese pressure, capable of reducing friction resistance.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of special-shaped Self-support packing bag, comprise a bag body, the bag end and be arranged at the bag sack of end with it, described bag body is to be made up of outer bag body and the inner packing layer of being located at described outer bag body inside, the edge at the described bag end is connected with the lower edge of described outer bag body and forms external packing layer, between described external packing layer and described inner packing layer, be provided with cavity, described external packing layer and described inner packing layer are thin bottom, top slightly and top is ") (" shape, bottom is the ampuliform of " () " shape, and described external packing layer and described inner packing layer connect as one in described sack place.
Further, described bag body is to be made up of outer bag body and multiple inner packing layer.
Further, described outer bag body is to be made up of two surface layers.
Preferably, described surface layer is the film that adopts PET plastics to make.
Further, the edge of described surface layer and the edge at the described bag end are provided with high frequency heat flanging.
Further, between described external packing layer and described inner packing layer and between described inner packing layer inner packing layer adjacent thereto, be provided with cavity.
Further, the described bag end is circular or oval.
Further, described external packing layer and described inner packing layer can be penguin shape or calabash shaped.
Preferably, the described bag end is the film that adopts PE plastics to make.
The utility model beneficial effect is: setting and the exterior and interior packing layer of the utility model at the bottom of by bag is the curved profile design that the center of gravity such as vase-like or penguin shape or calabash shaped is lower, can guarantee that the article that pack into support oneself and place more reposefully under Gravitative Loads; In addition, the utlity model has the Bag structure being formed by external packing layer and at least one inner packing layer, between described external packing layer and described inner packing layer and between described inner packing layer inner packing layer adjacent thereto, be provided with cavity, not only the article that pack into are had to certain buffer action, tensile strength, peel strength and percentage elongation are improved, strengthen resistance to abrasion and leak tightness, reduced friction coefficient.
