| 摘要 |
The present invention relates to a multilayer PET sheet and a manufacturing method thereof. The method for manufacturing a PET sheet comprises the steps of extruding a multilayer PET layer (41), which includes a first layer (411) and a second layer (412) composed of two different PET materials, from a multilayer extruder; and molding a sheet while simultaneously heat-bonding decoration films (51, 52) on the reverse side of the extruded multilayer PET layer (41). Accordingly, the highly glossy decoration PET sheet having the decoration films with a pattern on the reverse side is manufactured in a multilayer structure by using polyethylene terephthalate glycol (PET G) and polyethylene terephthalate antistatic (PET A). Therefore, a highly glossy decoration PET sheet having high economical efficiency and an antistatic function can be provided. |
