PET Plastic (Polyethylene Terephthalate) Selection Guide

Features of PET

Advantages

• Clarity: PET offers exceptional optical clarity, making it ideal for packaging applications where product visibility is essential.

• Recyclability: PET is highly recyclable, and rPET is widely used to create sustainable packaging and textiles.

• Lightweight: PET is lightweight, which is particularly advantageous in packaging for reduced shipping costs and improved fuel efficiency.

• Chemical Resistance: PET is resistant to many chemicals, ensuring its stability in various environments.

• Durability: PET containers are shatter-resistant, reducing the risk of breakage during transportation and handling.

• Barrier Properties: PET can be coated or laminated to provide enhanced barrier properties, making it suitable for food and beverage packaging.

Disadvantages

• Not Suitable for High-Temperature Applications: PET has a lower heat resistance compared to some other engineering plastics. It may soften or deform at elevated temperatures.

• Limited UV Resistance: PET is sensitive to UV radiation and may degrade when exposed to prolonged sunlight. UV stabilizers can be added to mitigate this issue.

• Environmental Concerns: Although PET is recyclable, it can persist in the environment for a long time if not properly managed, contributing to plastic waste.

Common Applications of PET

• ​Medical Devices: PET is used in medical device packaging and components due to its biocompatibility and resistance to chemicals used in healthcare settings.

• Electronics: PET is used for manufacturing electronic components and device enclosures due to its electrical insulating properties.

• Automotive: PET is employed in automotive interiors, including headliners, seat upholstery, and door panels, thanks to its durability and versatility.

• Beverage Packaging: PET is widely used for bottling beverages, including water, soft drinks, and juices, due to its clarity, lightweight nature, and recyclability.

• Food Packaging: PET is used for various food packaging applications, such as containers for salads, fruits, and deli items, as well as blister packs and clamshell packaging.

• Textiles: rPET is used to create sustainable textiles for clothing, carpets, and accessories.

• Cosmetics and Personal Care: PET is commonly used for packaging cosmetics, lotions, and personal care products due to its clarity and durability.

• Construction: PET sheets are used in construction for glazing and interior applications due to their transparency and lightweight properties.
