[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A novel degradable PE wrapping film comprises: a wrapping film 1, wherein the wrapping film 1 comprises two groups of self-adhesive layers 101, wherein an antistatic layer 102 and an anti-ultraviolet layer 103 are arranged inside the two groups of self-adhesive layers 101, a first anti-slip block 2 is arranged on the upper side of the upper self-adhesive layer 101, and a second anti-slip block 3 is arranged on the lower surface of the lower self-adhesive layer 101.

[0022] The two sets of self-adhesive layers 101 are made of polyhydroxyalkanoate material, which is a biopolyester synthesized by microorganisms and has good biodegradability. This means that after use, the self-adhesive layer of polyhydroxyalkanoate material can be decomposed by microorganisms in the natural environment, thereby reducing the burden on the environment. In addition, the production and use of polyhydroxyalkanoate is also in line with the concept of "carbon reduction" and helps to reduce greenhouse gas emissions. Polyhydroxyalkanoate has the characteristics of structural diversity. Its composition can be changed by changing the strain, feed, and fermentation process to obtain different properties. This makes polyhydroxyalkanoate have obvious advantages in application and can meet the needs of different application scenarios. Polyhydroxyalkanoate has good thermoplasticity and piezoelectricity. These properties make polyhydroxyalkanoate an ideal material for manufacturing self-adhesive layers. The self-adhesive layer needs to have a certain viscosity and elasticity in order to tightly wrap the packaged items. These properties of polyhydroxyalkanoate can ensure the quality and durability of the self-adhesive layer.

[0023] The antistatic layer 102 is made of conductive mica powder. Compared with traditional surfactant-type antistatic films, the antistatic performance provided by conductive mica powder is more durable because it is based on the conductivity of the filler itself. Since the antistatic performance of conductive mica powder is less affected by environmental humidity, the PE wrapping film can maintain a stable antistatic effect under various environmental conditions. Conductive mica powder, as a mineral filler, will not cause long-term pollution to the environment, which is consistent with the environmental protection concept of degradable PE wrapping film. Although mica powder itself is not a degradable material, its use in degradable PE wrapping film contributes to the environmental protection design of the overall material.

[0024] The anti-ultraviolet layer 103 is made of natural UV absorber material. Natural UV absorbers such as lignin can effectively absorb ultraviolet rays and reduce polymer degradation caused by ultraviolet rays, which helps to protect the PE wrap film from harmful ultraviolet rays in sunlight and extend its service life. The use of natural UV absorbers helps to reduce the impact on the environment because they are generally biodegradable and will not accumulate in the environment like some synthetic UV absorbers, causing long-term pollution.

[0025] The first anti-slip block 2 is configured as a circular structure. The anti-slip block of the circular structure has a raised design, which increases the friction area in contact with the packaged items, which helps prevent the items from sliding during transportation and improves the stability of the packaging. The circular structure can disperse the force more evenly when under pressure, reducing stress concentration on a specific point, thereby reducing the risk of damage to the items due to local pressure.

[0026] The second anti-slip block 3 is configured as a prismatic structure. The anti-slip block with a prismatic structure can penetrate into the surface of an object due to its sharp edges and corners, providing a stronger grip, which is particularly important in situations where heavier objects need to be supported or stability needs to be maintained on an inclined surface.

[0027] The wrapping film 1 is evenly provided with tear-off grooves 4 on both sides. The design of the tear-off grooves allows the user to tear off the wrapping film quickly and easily during use, which not only reduces the time for opening the package, but also avoids the risk of accidental damage to the packaged items due to the use of sharp tools such as blades. This design can also provide an anti-slip effect to a certain extent, because the edge of the tear-off groove can increase the friction between the packaged items and the packaged items, thereby enhancing the stability of the package.

[0028] It should be noted that the equipment structure and drawings of the utility model mainly describe the principle of the utility model. In terms of the technology of the design principle, the settings of the power mechanism, power supply system and control system of the device are not fully described. On the premise that the technical personnel in this field understand the principle of the above utility model, the details of the power mechanism, power supply system and control system can be clearly known. The control method of the application document is automatic control through a controller, and the control circuit of the controller can be realized by simple programming by the technical personnel in this field;
