Description

Technical Field

[0001] The utility model relates to the technical field of barrier films, in particular to an ultraviolet barrier film structure. Background Art

[0002] Barrier film is made of polyethylene terephthalate as raw material, which is made into thick sheets by extrusion and then stretched into thin film materials. Polyester film, environmentally friendly film, PET film, milky white film and other printing and packaging consumables are widely used in barrier steel industry, building materials industry, printing industry, medicine and health.

[0003] According to the utility model patent announced as: CN208469236U, a transparent high-barrier film with UV protection is disclosed, and its beneficial effects are: a transparent high-barrier film with UV protection, which includes, from top to bottom, a polypropylene surface layer, a polyethylene layer, an EVOH (ethylene / vinyl alcohol copolymer) layer, an EVA layer, and a nylon resin layer, wherein an ultraviolet absorber layer is arranged between the EVA layer and the nylon resin layer, and square pits are regularly arranged on the EVA layer near the ultraviolet absorber layer, and square pits are regularly arranged on the nylon resin layer near the ultraviolet absorber layer.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. It is understandable that the drawings are only provided for reference and illustration, and are not used to limit the utility model. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0017] Please refer to Figure 1 and Figure 2 in, Figure 1 A schematic structural diagram of a preferred embodiment of an ultraviolet blocking film structure provided by the utility model; Figure 2The schematic diagram of the structure of the ultraviolet blocking layer and the adhesive layer in the utility model.
