1. Raw materials and applications of plastic bottles
Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials. After adding corresponding organic solvents, they are heated at high temperatures and then blown, extruded, or injection molded through plastic molds. plastic container.
Mainly used for liquid or solid disposable plastic packaging containers such as beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs. Plastic bottles have the characteristics of not easily broken, low cost, high transparency, and food-grade raw materials.



2. Advantages of plastic bottle recycling
However, with the improvement of people's living standards, the use of plastic products continues to increase. As a common packaging container, plastic bottles are ubiquitous items in human daily life. However, if they are discarded at will, they will cause serious pollution to the environment. Therefore, recycling plastic bottles is crucial.

Recycling plastic bottles can reduce pollution to the natural environment. Recycling plastic bottles can effectively reduce the accumulation of garbage. It takes hundreds of years or even longer for plastic products to decompose in nature. A large number of plastic bottles are discarded in the natural environment, which not only affects the beauty of the landscape, but also affects the land and water sources. It causes long-term pollution, affects ecological balance, and may also cause harm to wild animals and plants. Through recycling, these plastic bottles can be processed and used again, reducing the negative impact on the natural environment.

Recycling plastic bottles helps conserve resources. The production of plastic bottles consumes a large amount of resources such as petroleum. Recycling and reuse can reduce the mining of new resources, help protect the environment and save energy.

Recycling plastic bottles can promote resource recycling. Through recycling and reprocessing, discarded plastic bottles can be converted into new plastic products, realizing the reuse of resources and extending the service life of resources.
Finally, recycling plastic bottles also creates jobs. The waste recycling industry is a booming field, and by recycling plastic bottles, more jobs can be created and economic development can be promoted.

3. Plastic bottle recycling process
The plastic bottle recycling machine is a mechanical equipment specially used to process and recycle waste plastic bottles. It mainly includes the following steps:

Unpacking, sorting and label removal of plastic bottles: Break up the compacted waste plastic bottles and sort them manually or automatically to remove impurities, metals and different types of plastic bottles for classification. At the same time, the labels carried on the plastic bottles are removed. The equipment is equipped with a screw loader and a bounce screen to remove impurities and dust carried on plastic bottles.



Plastic bottle crushing: The classified plastic bottles are sent to the crusher for crushing processing, which breaks large plastic bottles into uniform plastic flakes to prepare for subsequent processing.



Plastic bottle washing: The broken plastic sheets are cleaned through a cleaning machine to remove surface dirt and residues to ensure that the reused plastic particles are clean and pollution-free.



Plastic particle regeneration: The cleaned plastic flakes are reprocessed through a plastic granulator. After heating, compaction, extrusion, filtration, cutting, etc., recycled plastic particles or raw materials are finally produced, which can be used for the extrusion of new plastic products. .



The working principle of plastic bottle recycling equipment is to effectively process discarded plastic bottles through mechanical force and processing technology, realize the reuse of resources, and achieve the purpose of recycling.
