Benefits And Applications of PET Plastic Packaging
PET (polyethylene terephthalate) is a widely used thermoplastic polymer in packaging, known for its clarity, chemical resistance, and food safety. It is produced mainly through thermoforming and blow molding processes, used for various applications such as food containers and cosmetic packaging. PET is highly recyclable, lightweight, and offers barrier properties that enhance product shelf life while being an environmentally friendly option.

Benefits And Applications of PET Plastic Packaging
- 1.
- 2. Polyethylene terephthalate (PET)is a commonly used plastic in the packaging industry. Common PET products include: • Take-out containers • Baked goods containers • Bottled water • Ketchup • Jars (peanut butter and mayonnaise) • Juices and carbonated drinks • Frozen foods • Cosmetics • Household products
- 3. Composition of PETPlastic PET is a thermoplastic polymer resin from the polyester family. It is a polymer that is formed by combining modified ethylene glycol and purified terephthalic acid or dimethyl terephthalate. Although its name contains polyethylene, PET does not contain polyethylene.
- 4. PET Plastic Characteristics • High clarity • Good chemical resistance • Good gas and moisture barrier • High impact resistance • Medium rigidity (semi-rigid to rigid) • Medium scratch resistance • Food contact safety • Temperature tolerance of -50 degrees F to 110 degrees F
- 5. Origins of PETPlastic Although PET plastic was patented in 1941, the first PET bottle was not produced until 1973.
- 6. How are PETplastics made? There are two primary processes for producing a PET package. • Thermoforming – a process by which a sheet of PET plastic is heated and shaped using a mold into the desired shape. • Blow Molding – typically used to make containers with narrow mouths
- 7. Thermoforming vs. BlowMolding PET Plastics Thermoforming allows for custom shaping of PET plastic into any desired shape. PET plastic is often used to produce clamshells, bakery containers or take-out containers. Blow molding is primarily used to create bottles.
- 8. Why PET Plastic? PETplastic has a variety of characteristics that make it desirable for use as packaging material. • PET is suitable for varied uses. Some of the factors that make it so versatile include: • Transparent color • Lightweight nature • Strength • Shatterproof qualities • Inherent barrier-like qualities • Food safe material • Recyclability
- 9. Consumer Benefits ofUsing PET Plastic Containers PET plastic continues to be a prevalent material used by packaging companies for other properties including: • Ease of storage • Easy cleaning • Portability • Ability to re-seal
- 10. Benefits of UsingPET Plastic for Packaging Your Products In addition to being highly convenient for consumers, PET plastic is easy to use allowing for creativity when it comes to packaging design. PET allows for: • Distinctive brand packaging • Innovative packaging designs • A wide-array of applications
- 11. Benefits of UsingPET: Barrier-Like Properties PET’s inherent barrier properties protect and preserve packaged products against moisture (oxygen migration) and carbon dioxide. • Advanced technologies can increase protection for packaged products. These include: • Oxygen scavenger additives • Multi-layers and laminate with additional oxygen and carbon dioxide barrier properties • Silicon oxide (glass) coatings • Carbon coatings
- 12. Benefits of UsingPET: Lightweight Nature PET packaged products: • Increase efficiency in packaging and shipping • Enable lighter secondary shipping • Reduce fuel needs for shipping • Minimize greenhouse emissions
- 13. Benefits of UsingPET: Strength & Integrity PET plastic can be made to be semi-rigid to rigid. It is often the number one choice for small consumer products and food packaging due to it’s • Impact resistance • Scratch resistance PET’s natural ability to resist scratching and overall strength and integrity allow manufacturers to strive for lighter-weight packaging designs.
- 14. Benefits of UsingPET: Barrier-Like Properties PET’s inherent barrier-like properties make PET highly suitable for a variety of product packaging. Most importantly, PET’s protection against oxygen transmission increases shelf life and freshness. In comparison: • PET is ~9 times more effective as a barrier against oxygen transmission • PET is over 40 times more effective as a barrier against oxygen transmission
- 15. Benefits of UsingPET: Food Safety PET is a food-safe material, making it a convenient choice for packaging of food products. A few food safety elements of PET: • FDA approved for food and beverage contact • Low hazard (handling or inhaling) • Does not contain BPA • Does not contain heavy metals • Extremely low toxicity
- 16. Benefits of UsingPET: Recyclability Recycling of PET is well established, making it the most widely recycled across the world. About PET recycling: • PET can be recycled more than once • Almost all recycling programs accept PET bottles, and many accept PET thermoforms • PET can be recycled into fiber, fiberfill, carpeting, strapping, food and non-food bottles and PET packaging
- 17. Benefits of UsingPET: Recyclability PET recycling results in: • Conservation of raw materials • Reduced energy use • Reduced greenhouse gas emissions
- 18. Applications of PETPackaging: Food Industry Thermoformed PET plastic is often used in the food and restaurant industry in the form of baked good packaging and take-out containers. PET plastics in the food industry include: • Clamshells • Deli containers • Microwaveable food trays (frozen food) • Crystallized PET
- 19. Applications of PETPackaging: Other Industries PET can also be used for product packaging in the following industries: • Cosmetics (Health and Beauty) • Retail (Small Household Goods) The use of PET plastic for other industries usually comes in the form of blisters.
