Problems solved by technology

[0002] Now the express delivery industry is developing very rapidly. Almost everyone likes to buy things online. After our things are mailed, they are usually wrapped with bubble film to prevent them from being damaged during transportation. Because of the bubble film Lightweight, waterproof and drop-proof, it is the first choice for wrapping materials; the existing air bubble film is generally a double-layer single-sided air bubble film (one layer is a bubble film layer, and the other is a flat film layer). Light texture, good transparency, non-toxic and tasteless plastic packaging materials, double-layer single-sided bubble film is currently the most used and cheapest bubble film, but this kind of bubble film has poor pressure resistance and friction resistance due to the exposed bubbles , so that the service life of the bubble film is very low; in order to overcome the shortcomings of double-layer single-sided bubbles, a large number of bubble films with different structures have been developed. For example, Chinese patent CN201720113504.3 discloses a three-layer sandwich bubble packaging film. It includes a layer of air bubble interlayer and two layers of flat film layers. The flat film layers are respectively arranged on both sides of the air bubble interlayer. The air bubble interlayer and flat film layers are all LDPE films, which are easy to use, high in compressive strength, and shockproof. Good effect and help to improve work efficiency; Chinese patent CN201820690842.8 discloses a reinforced air bubble packaging film, including a layer of air bubble interlayer and two flat film layers, and the flat film layers are respectively arranged on both sides of the air bubble interlayer position, the air bubble interlayer and the flat film layer are all LDPE films, and it is characterized in that: the outer surface of one flat film layer is compounded with a reinforcing layer, and the reinforcing layer is composed of a fiber layer and a surface layer compounded on the outer surface of the flat film layer in sequence. Composition, the outer surface of the flat film layer is compounded with a fiber layer and a surface layer, which greatly improves the tensile and compressive properties of the bubble packaging film. The surface layer is made of PET material, which is non-toxic, weather-resistant, and chemical-resistant. In addition to these properties, its surface can be well adapted to the printing requirements, and it can be printed directly on the surface of the bubble packaging without re-packaging; but these existing technologies have shortcomings. The surface of the traditional three-layer double-sided bubble film There is no printing layer, the three-layer double-sided bubble film has a lot of bubbles, and the bubbles will be crushed during printing, so the three-layer double-sided bubble film cannot directly have a printing effect on the surface, so product information cannot be provided on the traditional bubble film. It cannot be used as an independent packaging material, and needs to be used together with other packaging materials with product information. It has a printing effect, but it can only have a printing effect on the surface after adding a reinforcement layer including a fiber layer and a surface layer on the surface of the three-layer air bubble film. It belongs to film printing with a medium, which increases the cost of raw materials and wastes resources; now There is an urgent need for a double-sided non-media printing bubble film with less material consumption, strong bubble pressure resistance and direct printing layer, and its preparation device and method
