Abstract
The utility model discloses an interlayer three-edge sealing bag, which comprises a three-edge sealing bag type bag body formed by plastic films through hot sealing, wherein the bag body comprises an upper film layer and a lower film layer, a middle film layer is also arranged between the upper film layer and the lower film layer of the bag body, an accommodating cavity is formed between the upper film layer and the middle film layer, and an accommodating cavity is also formed between the lower film layer and the middle film layer. The interlayer three-edge sealing bag is provided with two or more than two mutually isolated accommodating cavities, the structure can be used for simultaneously placing some articles incapable of being mixed in one bag body, and some special use requirements can be met.
Description
Technical field
The utility model belongs to the soft package technology field, is specifically related to a kind of interlayer three banding bags.
Background technology
Traditional packaging bag all has only a containing cavity that is used to put material, but for some special materials, liquid material for example, if having only a containing cavity, the information of its specification sheets and so on then can only be printed on the bag outside face; But for some material, like medicine, specification sheets is often very long, can print Wan on the bag outside face, just must prepare a box more in addition, all is placed in the box together with specification sheets the pharmaceutical packing bag is housed.For other complete medicines, when for example existing solid has liquid again, then can only it be contained in the different packaging bags.So for some special purposes, the conventional bag pack just can not very perfectly be dealt with problems, its structure exists needs improvements badly.
The utility model content
The purpose of the utility model provides a kind of interlayer three banding bags that can put the multiple article that can not mix.
Realize the utility model technical scheme be: a kind of interlayer three banding bags, comprise the three banding pocket type bags that form by the plastic sheeting heat-sealing, said bag comprises upper film layer and following thin layer; Said bag also is provided with middle thin layer between upper film layer and following thin layer, form a containing cavity between said upper film layer and the middle thin layer, also forms a containing cavity between following thin layer and the middle thin layer.
In the such scheme, said upper film layer, middle thin layer are identical with following thin layer size, and the position of the heat-sealable area when sealing into bag is identical.
In the such scheme, said upper film layer is the composite film that is combined into one by enhancement layer, barrier layer and hot sealing layer with following thin layer.
In the such scheme, said enhancement layer is the polyethylene terephthalate rete, and barrier layer is an aluminium foil layer, and hot sealing layer is polyethylene film layer or cast polypropylene film rete.
In the such scheme, when the hot sealing layer in said upper film layer and the following thin layer was polyethylene film layer, said middle thin layer was a polyethylene film layer.
In the such scheme; When the hot sealing layer in said upper film layer and the following thin layer is the cast polypropylene film rete; Thin layer is the cast polypropylene film rete in said; Or the composite film that is combined into one by cast polypropylene film rete, polyethylene terephthalate rete and cast polypropylene film rete, or the composite film that is combined into one by cast polypropylene film, aluminium foil layer and cast polypropylene film rete.
In the such scheme, comprise two middle thin layers at least, also form a containing cavity between two adjacent middle thin layers.
The utlity model has positive effect: (1) the utility model is owing to be provided with middle thin layer; So have two or more and isolated each other containing cavity; This structure can be used in a bag, putting simultaneously some article that can not mix; For example in a containing cavity, put into pressed powder, in another containing cavity, put into liquid material; Perhaps in a containing cavity, put into liquid material, in another containing cavity, put into the papery specification sheets; So the utlity model has good in-use performance, can satisfy some special user demands.
