1. Limestone and other stones
2. The main component of the stone environmental protection bag is calcium carbonate, and the calcium carbonate powder is extracted from stones such as limestone.
3. The first step is to put the calcium carbonate powder and various ingredients into a large jar-shaped mixer, and stir it thoroughly to form a "dough".
4. The agitated material is loaded into a granulator and becomes a mung bean-sized masterbatch.
5. Finished stone environmental protection bag.
6. After the bag making and cutting of the machine, the environmental protection bags are taken off line.
7. Rolled substrates will be printed with different patterns and texts according to customer's customized requirements.
8. The collected masterbatch is sent to the machine through the pipeline to blow the film. A thin "plastic" film was scooped out as a substrate.
