Description

Technical Field

[0001] The utility model relates to the technical field of label film preparation devices, in particular to a yellowing-resistant and highly transparent label film preparation device. Background Art

[0002] Yellowing-resistant and highly transparent label film is a special material used in label and packaging industries. It has the characteristics of yellowing resistance, high transparency and good printing performance.

[0003] Before the production of label film, raw materials need to be prepared to ensure that the quality of raw materials meets the requirements. Usually, the resin raw materials are melted to make it flowable, and then the label film is obtained after basic molding and cooling and solidification. When melting the resin raw materials, it is mostly necessary to manually add the raw materials into the device for melting, which also leads to low efficiency and increased labor intensity. In addition, cooling rollers are often used when cooling and solidifying the label film. When the cooling water in the cooling roller is recycled, the cooling of the label film by the cooling roller may cause the temperature of the cooling water itself to rise. Recycling may have the disadvantage of poor cooling effect. Therefore, it is necessary to design a yellowing-resistant and highly transparent label film preparation device. Utility Model Content
