Many local governments and waste collection agencies have started to collect post-consumer PET separately from other household waste. [2],[3], Polyethylene terephthalate can also be used as the main material in making water-resistant paper.[4].

There are both industrial- and consumer-related uses for PET plastics. Understanding more about the history of PET, as well as the chemical properties, will allow you to appreciate this plastic even more. The properties of PET make it ideal for a number of different uses and these advantages make it one of the most common plastics available today.

PET is largely used for synthetic fibers, also known as polyester. Our business is the design, creation, and production of effective, yet cost-efficient packaging for the retail, medical, electronics, industrial, and food industries. [6] In Japan, overseas market pressure led to a significant cost reduction in the domestic market. These are removed by plastic granulation, resulting in pure PET fragments, or "PET flakes".

PET can be modified with additional polymers as well, making it acceptable and usable for other uses. In many countries, PET plastics are coded with the resin identification code number "1" inside the universal recycling symbol, usually located on the bottom of the container. Unlike clear varieties, PET with unique color characteristics are only useful to the particular manufacturer that uses that color.

In 2009 3.4 million tons were used to produce fibre, 500,000 tons to produce bottles, 500,000 tons to produce APET sheet for thermoforming, 200,000 tons to produce strapping tape and 100,000 tons for miscellaneous applications. These plastics are a type of thermoplastic polymer resin, useful in various applications including in synthetic fiber production, in containers containing food and in thermoforming applications.

[14], Increasing energy prices may increase the volume of recycling PET bottles.

It can be used as a fiber in polyester-based carpeting.

In industrial applications, it can be very effective for strapping or in film and can be useful in the creation of automobile products including fuse boxes and bumpers. The safety of PET for food, beverage, pharmaceutical and medical applications has been repeatedly demonstrated through extensive studies, regulatory approvals, testing, and its widespread acceptance for more than 30 years. PET plastics or polyethylene terephthalate is used in many different products. It is very strong and has impact-resistant properties as well.

The resin pellets are then heated to a molten liquid that can be easily extruded or molded into items of practically any shape.

Polyester can be dried and amorphous flake crystallized and dried within only about 15 minutes down to a moisture level of approx.

It has a superior level of stability making it versatile and strong.

Bericht Modul 3 + 4 - BAFU: Verwertung Kunststoffabfälle Schweiz. This resin is commonly used in beverage bottles and many thermoformed plastic packaging clamshells, blisters, and trays. There are many different uses for PET. [7] For material recovery facilities, colored PET bottles are therefore a cause for concern as they can impact the financial viability of recycling such materials.

In addition, most communities recycle this type of plastic, which allows it to be used again and again. Fragile Packaging When used for containers and other purposes, it is called PET or PET resin. It is commonly used in bottles and other plastic containers.

It is also popular for packaging salad dressings, peanut butter, cooking oils, mouthwash, shampoo, liquid hand soap, window cleaner, even tennis balls.


For the recycling of polyester it is typical to integrate a screen changer into the extrusion line.

It has a low coefficient of friction making it useful in various applications in which other plastics are not. UPPI is a worldwide developer, manufacturer and marketer of specialized, custom thermoformed plastic packaging. It is a lightweight plastic that can be made into a number of different products. The cost of the plastics other than PET bottles remained high. Although its raw materials are derived from crude oil and natural gas, it enjoys a very favorable sustainability profile in comparison to glass, aluminum and other container materials.

The empty PET packaging is discarded by the consumer, after use and becomes PET waste. Esterification reaction between terephthalic acid and ethylene glycol, OR, Trans-esterification reaction between ethylene glycol and dimethyl terephthalate, Blow molding is generally used to produce transparent bottles, Mold temperature should lie between 10 and 50°C, Mold temperature: 140-160°C to obtain a crystalline PET (for technical applications), For transparent applications, mold temperature should lie between 10 and 50°C, Screw with an L/D ratio of 18-22 is recommended, PET is generally extruded to produce films and sheets (can be thermoformed after), Recommended hot end temperature: 240 and 260°C, Fiber for carpet, fleece jackets, comforter fill, and tote bags, Containers for food, beverages(bottles), and non-food items. After exported bales were taken into account, 1.12 million tons of PET flake were produced. Since the polymer is inert, it is resistant to attack by micro-organisms, and won't biologically degrade.

One of the most common is for drink bottles, including soft drinks and more. Recycling companies further treat the post-consumer PET by shredding the material into small fragments.

The contaminants are usually collected on woven wire screens which are supported on a stainless steel plate called a ‘breaker plate’—a strong circular piece of steel drilled with large holes to allow the flow of the polymer melt. Mechanicsburg, PA 17050, Phone: 800-544-6649 Almost every municipal recycling program in North America and Europe accepts PET containers.
