Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bags, and in particular relates to a high-barrier EPE packaging bag. Background Art

[0002] Packaging bags refer to bags used to package various supplies, which make it convenient to transport and store goods during the production and circulation process. Different types of packaging bags are used according to people's different needs. High-barrier packaging bags are one of them. The existing high-barrier packaging bags have a single structure, and the sealing cover at the bag mouth is not provided with a protective structure, which may cause the sealing cover to be opened in advance, and the safety of the packaging bag is poor.

[0003] The patent with application number 202121129614.1 discloses a high-barrier packaging bag, including a bag body and a composite film. The bag body is made of a composite film. The composite film includes a waterproof layer, a thermal insulation layer, a base layer and a wear-resistant layer. The waterproof layer is arranged on the inner side of the bag body, and the wear-resistant layer is arranged on the outer side of the bag body. Grooves are arranged on both sides of the bag body, and an extrusion sleeve is connected in the groove, and the bottom end of the extrusion sleeve is in contact with the bottom end of the groove.

[0004] The above technical solution forms a fixed limit on the sealing cover through the sleeve ring, so that the sleeve ring must be removed before unpacking, thereby facilitating the judgment of whether the sealing cover has been opened in advance. However, since the sleeve ring is mounted on the sealing cover through a connecting belt, there is no connection between the sleeve ring and the threaded head, and the sealing cover remains fixed after being disassembled and replaced, resulting in the sealing cover being able to be reset after being opened, and the safety of the packaging bag is poor.

Since the broken connecting cone and connecting block after the sealing cover is unscrewed cannot be repaired, the safety of the packaging bag is ensured. Multiple inflatable portions are fixed on the outer wall of the packaging bag body, and air is added to the inflatable portion through an air intake pipe on the rigid air intake portion, so that the inflatable portion protects the outer wall of the packaging bag body after expansion, thereby improving the safety of the packaging bag body during transportation, and when protection is not needed, the sealing plug is unscrewed to exhaust air through the exhaust pipe.

[0010] Preferably, an anti-slip portion is fixed to the bottom end of the inner wall of the packaging bag body, and the bottom end of the sealing plate abuts against the anti-slip portion.

[0011] Furthermore, a protrusion is fixed to the bottom wall of the sealing plate, and a sealing ring tightly connected to the packaging bag body is nested in the outer wall of the sealing plate.

[0012] Furthermore, an air intake pipe connected to a plurality of inflation parts is fixedly mounted on the side wall of the rigid air intake part, and a one-way valve is embedded in the air intake pipe.

[0013] Furthermore, an exhaust pipe is fixedly mounted on the side wall of the rigid air inlet portion, and sealing plugs are threadedly inserted into the side walls of the exhaust pipe and the air inlet pipe.
