PET flakes is constantly growing industry. PET stands for polyethylene terephthalate. In very simple words PET flakes are obtained from PET bottle wastes after a series of procedures. Such as sorting, washing, grinding, drying, etc. PET Bottles are the most commonly used product or commodity. It is used for aerated drinks or simply packaged water bottles. Once the potential of these bottles is used they end up majorly into the landfills. Which contributes to the big chunk of waste. To reduce this waste, PET bottles are recycled into flakes or chips.

We shall see in brief about PET flakes and their various applications. To know more about it, keep reading!
PET (polyethylene terephthalate) flakes are membrane-like structures. They're prepared from used PET bottles. They exhibit similar properties, such as chemical structure, microstructure, the permeability and hydrophilicity. These properties make it very efficient for manufacturers to use as raw material in the plastic industry. Chemical formula for PET flakes is (C10H8O4)n.
But how Is Polyethylene Terephthalate Made? Polyethylene terephthalate is made from ethylene glycol. Ethylene glycol is usually called 'MEG,' which stands for monoethylene glycol. So the PET is made from a combination of MEG and dimethyl terephthalate (DMT).
Harmonized System (HS) for PET flakes:-
HS stands for Harmonized System. It is a standardised numerical method for classifying traded products. HS varies from country to country. Their HS code for PET flakes in India is .

Pet flakes are widely used in the manufacturing of products used in our day-to-day life. It is very easy to notice that we have regular contact with these products made by PET flakes partially or entirely. Toothbrush, milk cans, water bottles, food containers, packaging material, shampoo bottles, toys , clothing fibres, carpets, chairs etc. These are the regular products made from pet flakes. Let's see some examples of industries that use them:-
As there are different grades of plastics similarly there are different grades of PET flakes. Different grades depend on where it is obtained from such as beverage bottles, water bottles, food containers and shampoo containers etc. In industry PET is identified by grade to check eligibility in further different sectors of use. For example the flakes obtained from shampoo containers cannot be used for manufacturing of edible category containers, hence these are identified by different grades systems.
Grading system also checks the impurities that may be present. These impurities are measured in ppm( parts per million). These can be PVC, PE, wood, stone etc. These non-polymeric impurities can result in the quality of the end product.
Some grade are:

Due to this there is a need for strict administrative regulations to explore various recycling techniques to handle plastic waste. Like any other polymers, the recycling of PET can also be divided into different categories. The recycling process takes place in following steps:-
Sorting into different categories and grades of pet bottles, different coloured bottles are separated for further processing. Removal of label, caps and bottle neck rings. As these bottles are post-consumed bottles it may contain food leftovers and other adhesive. It is further washed and dried for prevention of any contamination.
These plastic bottles are further processed into shredders. In this process shredders cut plastic bottles into tiny membranous structures. Thus, shredders help recover waste during different industrial processes, such as moulding, trimming, and casting.
These shredded PET are now processed through a belt conveyor. It helps to get rid of dusty unwanted particles. Belt conveyor process is important to obtain uniformity in the raw material characteristics.
Belt conveyors are connected to the washing tank where the PET materials get transferred. Here membranous PET is washed with caustic soda and NaOH resulting in the removal of any impurity. There are two types of washing involved in its manufacturing. It's decided according to the desired grade.
Recycling process of PET flakes
Even though the plastic waste in India is going overboard, there is very little raw material that reaches the recycling plant. If the recycling material is less, availability for PET flakes will also be considerably less. To cater with this less availability of raw materials for recycling the government of India raised a ban from the import of plastic waste for recycling which was imposed in .
In order to import plastic waste for recycling one must have a licence which is issued by the ministry of environment, forest and climate change(MoEFC).
So Documents required are:-
It's very much interesting to know that the PET recycling industry in India had a turnover of around Rs. 3,500 crores in . In the turnover was Rs. crores plus. The Indian recycling industry consists of both unorganised and organised recyclers. The PET recycling rate in India is 90%.
There are value-added products made from Recycled PET(RPET). The Indian PET recycling industry is expected to grow exponentially in the coming years, as RPET will also be used in direct food contact applications in the near future.In Fact, in the next 4-5 years, the Indian PET recycling industry's turnover will be Rs 13,500 crores plus!
PET polymers are highly resistant to moisture. Also PET is chemical resistant to organic material and water. Thus, it has a very high strength to weight ratio. It is highly transparent and comes in a variety of shapes and colours which offer a good choice in producing attractive products.
They help conserve raw materials in many different industries.
As we all know that PET is not a biodegradable plastic, which may be a disadvantage depending on the intended application. PET has lower heat resistance when compared to other polymers. Resins made from PET can oxidise, resulting in a degradation in the taste of food and beverages when the items have a long shelf life and are stored in PET packaging.

Buyer Listings Seller ListingsPolyethylene terephthalate (PET) may seem useful but its impact on the environment is quite harmful, if left untreated. PET flakes are the byproducts of the recycled PET materials and can be further recycled to form PET chips. They are a multi-purpose commodity, which can be used in various industries like concrete, textiles, furniture etc. In order to Recycle PET waste and sell as flakes, one must have a valid licence issued by the MoEFC and CPCB.
