Description

Technical Field

[0001] The utility model relates to the technical field of bubble bags, in particular to a pearlescent film bubble bag. Background Art

[0002] Bubble bags are transparent, flexible packaging materials made from high-pressure, low-density polyethylene, manufactured through a film-cutting and bag-making process. The principle is that air is trapped within the film, forming bubbles that act as a cushion and protect items from vibration or impact. Pearlescent film bubble bags are suitable for packaging a variety of small items, providing both shock absorption and cushioning while also enhancing the aesthetic appeal of the pearlescent film.

[0003] Chinese utility model patent CN221542646U discloses a bubble bag with good waterproof performance, which includes a bag body with a waterproof component provided at the front end of the bag body. The bubble bag with good waterproof performance can clamp and seal the bag opening of the bag body through the cooperation of the fixed cross bar, the clamping cross bar, the bolts and the threaded holes, thereby preventing water from entering the bag body and damaging the object. The cooperation of the groove, the fixed ring, the annular rubber rope, the mounting ring and the limit plate allows the bag opening to be separated from the fixed cross bar and fully opened when a large object needs to be inserted into the bag body, thereby preventing the bottom surface of the bag body from being completely fixed to the upper surface of the fixed cross bar, thereby preventing the bag opening from being fully opened and affecting the protection of the large object. The cooperation of the limit cavity and the limit ring plate can limit the bolts, thereby preventing the bolts from being separated from the clamping cross bar and being lost.

[0004] In order to prevent water from entering the bag body, the above-mentioned bubble bag with good waterproofness is provided with a fixed cross bar, a clamping cross bar, bolts and threaded holes. However, the above-mentioned bubble bag with good waterproofness does not have the function of waterproofing the bolts. The bolts, as connecting and fixing components, may corrode when exposed to a humid environment for a long time, thereby causing the sealing performance between the clamping cross bar and the fixed cross bar to deteriorate. The bag opening may not be able to effectively block the entry of water, causing the internal items to become damp or damaged. Utility Model Content

[0005] The utility model provides a pearlescent film bubble bag to solve the problems in the background technology.

[0006] The cam is fixedly provided with an outer wall of the bag body, and the outer wall of the bag body is provided with a pearlescent film.

[0007] Furthermore, the pearlescent film and the bubble film body are adhered to each other by glue.

[0008] Furthermore, a rubber pad is fixedly provided on the bottom of the clamping cross bar.

[0009] Furthermore, the nut is hexagonal, and the bottom of the protective shell is provided with a hexagonal groove adapted to the nut.

[0010] Furthermore, the protective shell is made of plastic.

[0011] Furthermore, a threaded hole adapted to the threaded rod is provided on the top of the fixing block, and the connection relationship between the fixing block and the threaded rod is a movable plug-in connection.

[0012] Compared with the existing technology, the utility model provides a pearlescent film bubble bag with the following beneficial effects:

[0013] 1. The pearlescent film bubble bag is provided with a pearlescent film. The pearlescent film not only has good waterproof and moisture-proof properties, can effectively prevent water vapor from eroding the goods and enhance the waterproof performance of the bag, but also has a pearl-like charming luster and rich colors, which can significantly improve the overall aesthetics of the packaging and enhance the texture of the packaging.

[0014] 2. The pearlescent film bubble bag is provided with a protective shell, an L-shaped rod, a movable plate, a rotating seat and a reset spring. After the threaded rod is fully inserted into the threaded hole, the L-shaped rod is pulled to the side away from the clamping cross bar, the movable plate moves accordingly, and the reset spring is deformed until the bottom of the protective shell is higher than the top of the nut. The L-shaped rod is rotated, and the rotating seat rotates in the clamping cross bar as the movable plate rotates. When the protective shell is aligned with the nut, the L-shaped rod is released. Under the elastic force of the reset spring, the movable plate drives the L-shaped rod to move, and then the nut is inserted into the hexagonal groove of the protective shell. The protective shell can therefore tightly wrap the nut, effectively isolating it from moisture and air, thereby slowing down the corrosion rate of the nut and extending the service life of the nut. At the same time, it also ensures the stability and reliability of the bag sealing structure, reducing the risk of economic losses and safety hazards caused by water leakage.
