PET Recycled Granules:

PET is a polyester, which has a chemical name of polyethylene terephthalate. It is naturally transparent and semi-crystalline plastic used widely for products used in our day to day life. PET polymer is better termed as “Polyester” in the textile industry. PET is widely used as a fiber for clothing as it is an excellent moisture barrier and also used for bottling and packaging on large scale. The major share of PET plastic produced comprises of synthetic fiber (up to 60%) and remaining 30% is for bottle production of the total global demand.

PET is a plastic resin and the most commonly used plastic material. Thousands of consumer products, beverages and food items are delivered and packaged within this material.

PET is a sound, ecological option because it is produced using 100% naturally occurring ingredients, while still providing excellent product clarity and printing finish.

Plastic granules are small balls of plastic that are poured into various plastic forming machines and turned into different types of parts.

Recycled plastics that are ground and have sheet shapes or sharp corners can not

They are easy to use in the input hoppers of the devices, and of course, when mixing, they always have a non-uniform composition with other materials due to their non-uniform size.

Therefore, consumers of these materials prefer their purchased materials as new raw materials in the form of granules or small plastic balls, which is done by a line called granule production line.

Pet Granules:

Pet Granules are produced from the recycling of mineral water bottles and soft drinks. By using the vacuum system, the bottle labels are removed. In the next step, the bottle caps are also removed.

The Pet bottles were washed after collection and using the municipal recycling plan they are disinfected. After this stage, the bottles are ground and become flakes.

Recycled PETs are in the form of small sheets with irregular dimensions and sharp corners, so in order to increase their quality when mixed, consumers generally tend to use its granular shape. Therefore, PET sheets produced using a special device to They become recycled pet granules.

A variety of waste recycling methods:

Mechanical recycling:

This step is actually a prerequisite for the physical and chemical recycling of PET. At this stage, the separation of contaminants maintains the quality of the final product.

Physical Recycling:

After mechanical recycling, recycled granules are produced that can be used alone. However, in some cases, some pure PET granules are added to it. This combination is used to produce low quality products. Due to the poor quality of the final product, physical recycling is less used among various recycling methods.
