Description

Technical Field

[0001] The utility model relates to the technical field of cast film moulds, in particular to a barrier cast film mould. Background Art

[0002] Cast film is a non-stretched, non-directional flat extruded film produced by quenching the melt. Cast film has excellent heat sealing properties and good transparency. It is one of the main packaging composite substrates and is used to produce high-temperature cooking films, vacuum aluminum-plated films, etc. In the production process of barrier cast film, a cast film mold is required. The cast film mold is generally fixed to the cast machine by bolts. After the cast film mold is fixed, if it needs to be removed for maintenance, it is necessary to use tools to remove the bolts used to fix the cast film mold one by one, which is time-consuming and labor-intensive, and the subsequent installation is also more troublesome. Therefore, a barrier cast film mold is proposed to facilitate the disassembly and subsequent installation of the cast film mold. Utility Model Content
