Description

Technical Field

[0001] The utility model relates to a bubble film packaging bag, belonging to a bubble film-covered packaging bag. Background Art

[0002] Bubble film is widely used in our daily life, especially in many packaging. It can be used to protect products and prevent them from being damaged. Bubble film is a product made of high-pressure polyethylene as the main raw material, with whitening agent, opening agent and other auxiliary materials added. It is extruded and blister-formed into bubbles at a high temperature of about 230 degrees. It is a new type of plastic packaging material with light texture, good transparency and no smell, also called bubble pad.

[0003] After searching, a bubble film packaging bag disclosed in the Chinese patent with announcement number CN218432606U has the following technical points: including a front bag sheet and a rear bag sheet, the front bag sheet and the rear bag sheet respectively including a first PE polyethylene film layer, a second PE polyethylene film layer, a PA nylon film layer, a third PE polyethylene film layer and an ink printing layer from the inside to the outside; the front bag sheet and the rear bag sheet respectively include a bag body and a bag mouth connected to the upper end of the bag body, and a PE polyethylene bubble layer is sandwiched between the first PE polyethylene film layer and the second PE polyethylene film layer of the bag body. The bag body of the utility model has high strength and toughness, is not easy to be damaged, is not easily corroded by external oxygen and water vapor, has good shockproof performance, and can provide shockproof protection for the items in the packaging bag.

[0004] The above scheme solves the following problems: first, although the packaging bags made of PE polyethylene material are easy to heat-seal and process, the bag body has poor strength and toughness and is prone to damage. External oxygen and water vapor can easily enter the bag body from the damaged parts to corrode the underwear, causing the underwear to change color and turn yellow; second, the existing packaging bags have poor impact resistance and shockproof performance. When the underwear is subjected to external impact, it is easy to deform and cannot play a shockproof protection role. However, it cannot package items of different thicknesses. When the packaging items are different, matching packaging bags must be produced, which wastes raw materials. At the same time, the old-fashioned bubble film is easy to break, and the shock absorption effect is not ideal, resulting in damage to the items during transportation. The disposable adhesive strips used for sealing are also wasteful, which increases a lot of costs.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
