What are the raw materials of plastic pellet machine

The raw material of the plastic pellet machine is waste plastic, which mainly has the following three aspects:

1. Waste plastics produced when producing new plastics

    1. During the maintenance, the plastic or unqualified plastic attached to the new plastic production equipment;

    2. Cleaning the plastic extruder waste and unqualified compounding plastic during the compounding process;

    3. Floor material during transportation and storage;

    4. The waste material generated during the molding process is commonly known as scrap material;

    These raw materials account for the smallest proportion of the entire waste plastic, but the quality of the particles made by the plastic pellet machine is also the best.

2. Waste plastics generated in secondary processing

     Secondary processing is usually the semi-finished plastic products purchased from the molding processing plant through transfer, sealing, thermoforming, mechanical processing, etc. into finished products, the waste generated here is often more difficult to handle than the waste generated by the molding processing plant.

For example, the wastes after printing and electroplating are very difficult and costly to remove the printed layer and electroplated layer. The value of recycled materials obtained by direct crushing or granulation is much lower. The waste edges and waste pears produced by thermoforming and mechanical cutting are relatively easy to recycle and regenerate, and the value of the recycled materials is relatively high.

3. Waste plastics generated after the use

     This type of waste plastic has a wide range of sources and complex usage conditions and must be treated before it can be recycled. Such waste plastics include:

    1. Waste plastics produced in agriculture, such as mulch film, greenhouse film, fertilizer bag, etc.;

    2. Waste plastics in urban household garbage, such as fresh-keeping bags, shopping bags, etc.;

    3. Packaging materials, foam shockproof pads, etc. in the home appliance industry;

    4. Building materials, pipes, etc. in the construction industry;

    5. Shrink film and stretch film in the filling industry;

    6. Bumpers and battery boxes removed from scrapped vehicles;

    7. Turnover boxes and egg trays in the food processing industry;

    8. Containers and waste man-made fiber yarns in the textile industry;

    9. Bags and barrels used in the chemical industry;

    10. Fishing nets and floats in fisheries.

    There are many types of waste plastic products in domestic garbage, and they are actually the main source of raw materials for plastic pellet machines. Including all kinds of packaging products, such as bottles, films, irrigation, etc.; daily-use products, such as barrels, basins, cups, plates, etc.; toy accessories, entertainment products, clothing and footwear, strapping ropes, packing straps, woven bags, Health care supplies, etc.
