or coated with a UV layer.
Electrical insulation Excellent electrical insulator
Flammability Generally considered self-extinguishing
Properties of barriers Good barrier against oxygen and carbon dioxide
Biocompatibility Generally considered biocompatible
Types of polyethylene terephthalate (PET)
Polyethylene terephthalate (PET) includes several types that vary in chemical composition, physical properties, and intended applications. Understanding these variations is essential to effectively use PET plastic in different industries.


1. PETG (modified PET-glycol)
PETG is a modified form of PET plastic first dataset that incorporates glycol during the polymerization process. This modification improves the impact resistance and toughness of the material while maintaining its clarity and ease of processing.

Manufacturers widely use PETG in applications requiring robust packaging, such as bottles, containers and technical parts. Its enhanced properties allow it to adapt to demanding environments where standard PET may not be sufficient.

2. Recycled PET (rPET)
Recycled PET, or rPET, is derived from post-consumer PET products such as bottles, which are collected, cleaned and processed for reuse. rPET plays an important role in sustainability efforts by reducing the consumption of virgin PET materials and minimizing waste.

It has similar properties to virgin PET, but may have a slightly different molecular structure due to the recycling process, which often tends towards amorphous characteristics. People use rPET to make new PET containers, fibers for textiles, and various other products, contributing to a circular economy.

3. Amorphous PET (APET)
Amorphous PET lacks a crystalline structure due to its rapid cooling during the manufacturing process. This rapid cooling prevents the polymer chains from forming ordered crystalline regions, resulting in a transparent material with excellent clarity.

Manufacturers commonly use APET to produce films and sheets for packaging applications that require critical transparency and visibility of contents. Compared to crystalline variants of PET, APET has a lower melting point, greater elasticity and better transparency, making it ideal for thermoforming processes.
