About Plastic Bottle Recycling

The plastic bottle contains three parts, the plastic bottle body, the bottle cap, and the trademark. The bottle cap is generally made of HDPE material, the bottle body is made of PET material, and the trademark is also non-PET material. Therefore, the cleaning and recycling of plastic bottles are generally to remove the caps and trademarks of non-PET materials and then retain the bottle body containing PET materials, and finally obtain PET flakes. The recycled PET flakes can be reused and used to make clothing fibers, or It is a recycled bottle.

Plastic Bottle Flakes Washing Recycling Process

Sorting plastic bottles

The sorting step is mainly to sort out impurities such as miscellaneous bottles, miscellaneous-colored bottles, and plastic films in waste plastic bottles. If the sorting step is not clean, then the cleaning process will not produce very good PET flakes.

Removing the label

This step is to remove the label from the plastic bottle. Since the trademark is generally different from the PET material, the trademark needs to be removed to obtain pure PET flakes. Removing the label on the PET bottle can be achieved by a manual or automatic de-labeling machine.

Crush plastic bottles

The entire plastic bottle was shredded into sheets using a plastic shredder. Since the plastic bottle caps are crushed along with the PET bottles, the crushed PET sheets contain non-PET material plastic bottle cap fragments.


The washing step is the most important step in the PET bottle flakes washing line, so it needs to go through cleaning steps such as pre-wash, main wash, and rinsing. The pre-wash process is generally to remove easily removable stains adhering to the surface of the bottle. If this process is done well, it can reduce the burden of the main washing process and reduce costs. The main washing process is to remove hard-to-remove stains such as oil stains and glue. The rinsing process has two functions, one is to rinse out the remaining floating material, and the other is to rinse off the cleaning agent adhered by the bottle maker.

Drying and dehydration

After cleaning, the PET sheet needs to be dried and dehydrated to meet the dry storage requirements.

Why Should PET Bottles be Recycled and Cleaned?

PET plastic bottles are widely used in our daily life, which greatly brings convenience to our lives. However, the large number of plastic products produced after use will pollute the environment. Plastic is difficult to decompose in the natural environment, causing pollution to the soil and the environment. Therefore, the recycling of plastic bottles and other plastic products has become a trend. PET bottles are products made of petroleum, and recycled plastic flakes are the main raw materials for replacing petroleum to produce chemical fibers. Therefore, the recycling of PET bottles reduces environmental pollution and excessive consumption of oil. The PET polyester chips produced by the PET bottle washing line are mainly aimed at medium and low-end industrial applications such as chemical fiber staple yarn and non-ferrous melt filling.
