Description

Technical Field

[0001] The utility model relates to the technical field of blow molding bottle material processing, in particular to a blow molding bottle material weighing device. Background Art

[0002] Plastics are polymer compounds made from monomers through addition or condensation reactions.

Plastic particles refer to granular plastics, which are often used as raw materials for plastic products. In the manufacturing process of plastic products, plastic particles need to be weighed and packaged.
