[0002] For plastic products such as disposable plastic bowls and milk tea plastic cups, the production method is usually to heat-melt the plastic into a strip coil, cut it into several discs or other shaped sheets, and then put the discs into a mold and make it into plastic cups through a hot pressing process. In the above process, after cutting and cutting several discs, the strip coil needs to be rolled up and reused through hot melting.
