Problems solved by technology

Plastic bags are mainly used in daily life, and paper bags are mainly used for express packaging and document transportation. After the bag is unsealed, its airtightness is obviously greatly reduced. When it is used for the packaging of industrial production raw materials, the internal objects are easy to leak out, and at the same time, the internal production raw materials are not easy to be completely taken out, resulting in waste of raw materials.

Embodiment 1

[0018] Such as figure 1 Shown is a schematic structural diagram of the present invention, the present invention is an easy-tear packaging bag, the bag mouth and the bottom of the bag are provided with easy-tear parts, and the bag mouth is also provided with a sealing part.

[0019] The easy-to-tear part includes a sealing strip 1 and a tear strip 2; the sealing strip 1 is co-located on the mouth of the bag and the bottom of the bag, and is connected to the mouth of the bag and the bottom of the bag through the tear strip 2, and the periphery of the tear strip 2 is connected to the mouth of the bag and the bottom of the bag. The upper and lower sides of the joint at the bottom of the bag are all punched with two rows of empty holes by steam, so that the tear strip 2 can be pulled apart.

[0020] The sealing part includes a sealing male strip 3 and a sealing female groove 4; the sealing male strip 3 is matched with the sealing female groove 4, and is arranged at the mouth of the...

Embodiment 2

[0022] The main structure of this embodiment is the same as that of Embodiment 1, the difference is that, as image 3 , the sealing male strip 3 and the sealing female groove 4 are arranged on the outside of the bag from top to bottom, and are located below the easy-tear part.

Abstract

The invention provides an easy-to-tear packaging bag. Easy-to-tear parts are arranged at a bag opening and a bag bottom, and meanwhile, a sealing part is further arranged at the bag opening; each easy-to-tear part comprises a sealing strip and a tearing strip; the sealing strips are arranged at the bag opening and the bag bottom in a matched manner and are connected with the bag opening and the bag bottom through the tearing strips; the sealing part comprises a male sealing strip and a female sealing groove; and the male sealing strip and the female sealing groove are matched with each other and are arranged at the bag opening in a matched manner. The easy-to-tear packaging bag can be used for storage of industrial production raw materials effectively, and sealed storage of residual raw materials inside the bag can be guaranteed when the raw materials are used incompletely; meanwhile, the easy-to-tear part at the bag bottom can be opened directly, and the raw materials inside the bag can be used completely, so that waste of the raw materials is greatly reduced; the easy-to-tear packaging bag is novel in structure, low in production cost and suitable for wide popularization and use;and the easy-to-tear packaging bag has the good market prospect.

Description

technical field [0001] The invention belongs to the field of packaging bags, in particular to an easy-tear packaging bag. Background technique [0002] Packaging bag refers to the bag used to pack various supplies, which makes the goods convenient to transport and store during the production and circulation process. It is widely used in daily life and industrial production. The more common ones are plastic bags and paper bags. Plastic bags are mainly used in daily life, and paper bags are mainly used for express packaging and document transportation. After the bag is unsealed, its airtightness is obviously greatly reduced. When it is used for the packaging of industrial production raw materials, the internal objects are easy to leak out, and at the same time, the internal production raw materials are not easy to be completely taken out, resulting in waste of raw materials. [0003] Therefore, it is a difficult problem that those skilled in the art continue to solve to devel...
