Sub-brand materials: Compared with genuine plastics, they do not meet the inspection standards when they leave the factory. Compared with genuine plastics, they fail to meet certain indicators, but they can still be used. When the same batch of products comes out, those that pass the inspection will be labeled with genuine labels, and those that are not fully qualified will not have labels, which is also called sub-brands. It is mostly used for plastic barrels that require high quality but are not used for food and medical packaging. Return material: also called water mouth material. After the new material is processed into a product, in addition to the gate and runner moldings other than the product, the unqualified products and sprues can be crushed and then materials used together with the new material can be added. Like the sub-brand materials, the processed plastic products are not used in the food and pharmaceutical industries. Recycled material: generally refers to the particles that are pulled out after various waste plastic products and corner scraps are recycled and crushed, and then regenerated by equipment. During the regeneration process, some additives can be added to enhance the physical properties of the plastic. It is mostly used in plastic packaging in the chemical industry, chemical plastic barrels, etc.
