PET-G is the abbreviation for Polyethylene terephthalate Glycol-modified and is a refined PET, which stands out for very high definition and transparency in thermoforming. Therefore, PET-G is often processed for visible parts and high-gloss blisters. However, the lack of UV resistance prevents the use of the thermoformed part in permanent outdoor applications.
The "G" in PET-G stands for Glycol. Glycol is added during polymerization in the production of PET-G and prevents the material from crystallizing under heat. This means: when the PET-G film is heated on the thermoforming machine, the material remains crystal clear even at high forming temperatures. Therefore, PET-G is also referred to as a plastic with maximum transparency and is often used for visible parts.

Compared to PET-A, PET-G has better low-temperature behavior and significantly improved thermoforming properties. Glycol provides better stretchability and formability of the material. Therefore, PET-G is used for demanding thermoformed parts when PET-A is no longer sufficient. Excellent formability makes very sharp contours and edges in the thermoformed part possible.

PET-G stands for polyethylene terephthalate glycol-modified and is a modified PET material. The addition of glycol ensures that PET-G remains crystal clear when heated and can be deep-drawn with particular precision. The plastic is known for its maximum transparency and sharp contours. Ideal for visible parts, displays and blister packaging.
