The multiple layer sheet and manufacturing method for making container

摘要

The present invention relates to a multilayer sheet for manufacturing a container and a manufacturing method thereof, capable of manufacturing a small number of the multilayer sheets for manufacturing the container and supplying the multilayer sheets with low costs. The present invention includes a preprocessing step (S) to manufacture a multilayer film sheet (110) by including a surface film adhesive spraying step (S1), a blocking film bonding step (S2), a blocking film adhesive spraying step (S3), and a laminate film bonding step (S4) and a thermal fusion step of a sheet (T5) to manufacture a single layer sheet (100). The present invention includes a postprocessing step (T) to selectively perform a cooling step (T6) to harden the single layer sheet (120) and a laminate film (115) of the multilayer film sheet (110) after the thermal fusion step of the sheet (T5).
