Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bags, and in particular relates to a plastic composite extrusion explosion-opening packaging bag. Background Art

[0002] With the improvement of people's living standards and changes in consumption habits, the requirements for packaging materials are getting higher and higher. Traditional packaging bags usually adopt a tear-off opening design. Although this design is simple and easy to use, it has some problems in actual use. First, the tear-off opening easily causes the bag body fragments to fall into the food, posing a safety hazard to consumers and easily causing food to scatter; secondly, the tear-off opening is not convenient and quick enough when opening the bag, and sometimes even requires the help of tools to complete it, which makes the bag opening troublesome.

[0003] In recent years, some new packaging bag designs have appeared on the market in an attempt to solve the above problems. For example, some packaging bags use a pre-cut line design, which guides users to tear the packaging bag along a specific path through pre-set cut lines; however, this design still has certain limitations. For example, the pre-cut line may not be obvious enough, and it is difficult for users to find the correct tearing position. Therefore, in order to solve the defects of the above-mentioned prior art and to further improve the safety and convenience of packaging bags, it is particularly important to develop a plastic composite extrusion burst-opening packaging bag. Especially for those application scenarios that require quick and convenient opening while ensuring the integrity of the contents, such as snack foods, medicines, etc., it is very necessary to find a solution that can ensure the sealing of the packaging bag and can be easily opened without generating bag fragments. Utility Model Content

[0004] The utility model aims at the above problems, makes up for the deficiencies of the prior art and provides a plastic composite extrusion burst-opening packaging bag.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A plastic composite extruded explosion-opening packaging bag comprises a packaging bag body, the packaging bag body is provided with a first end seal, a second end seal and a back seal, a blasting hole is opened on the front of the packaging bag body, and a blasting layer is sealed and connected to the blasting hole; the packaging bag body is filled with gas, the packaging bag body is bulged by the filling of gas, and the bulged packaging bag body can be squeezed by external force to rupture the blasting layer connected to the blasting hole.

[0007] As a preferred solution of the utility model, the packaging bag body includes a content contact layer, which is the innermost layer of the packaging bag body, and is compositely connected to the outside of the content contact layer with any one, two or three layers of a reinforcement layer, an antistatic layer and an enhanced coating layer.

[0008] As another preferred embodiment of the present invention, the blasting layer is compositely connected to the exposed content contact layer at the blasting hole.

[0009] As another preferred embodiment of the present invention, a bursting hole is provided on the front side of the packaging bag body near the first end seal, or a bursting hole is provided on the front side of the packaging bag body near the second end seal.

[0010] As another preferred embodiment of the present invention, the blasting layer and the layer in contact with the contents are both made of CPP cast polypropylene film.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides a plastic composite extrusion bursting opening packaging bag. By arranging bursting holes on the packaging bag body and sealing and connecting the bursting layers on the bursting holes, and then extruding the bulging packaging bag body by external force, the packaging bag can be burst at the arranged bursting layer, and the bursting layer is broken, thereby opening the packaging bag. In this way, the danger of accidentally ingesting torn bag fragments caused by the previous tearing opening method can be avoided, the safety is improved, and the bag opening is convenient. At the same time, the packaging bag of the utility model also has the characteristics of good sealing and airtightness. Moreover, at the moment of squeezing and bursting the opening, the pressure can be relieved and the mood can be soothed, the food will not be scattered, and the food is protected. Moreover, the squeezing and bursting opening method is not dangerous. BRIEF DESCRIPTION OF THE DRAWINGS
