Description

Technical Field

[0001] The utility model relates to the technical field of inkjet advertising films, in particular to a super-matte weather-resistant inkjet advertising film. Background Art

[0002] In the application process of modern advertising films, advertising films mainly use PET materials. During production, the PET base layer is directly spray-painted, and then coated after the spray-painting is completed. However, this type of spray-painted advertising film is mainly used with the interlayer side between the films facing outward during use. During application, it is easy to cause the outer film to fall off due to problems such as water ingress, and then cause the spray-painted coating of the advertising film to become dirty. At this stage, it needs to be sealed with edge sealing. Although this can seal the side of the film layer, it cannot effectively prevent water from entering between the film layers. In view of this, in-depth research was conducted on the above-mentioned problems, resulting in this case. Utility Model Content
