Clarity and toughness
PETG supports tough clear forms, PET is central to clear packaging, and PVC offers versatile forming and print routes. Polycarbonate can serve demanding covers but needs tighter heat control.

Vacuum Forming Material Selection Guide
Material selection for vacuum forming depends on more than softening temperature. The sheet must heat evenly, draw into the tool, release, trim and perform in the final application.

Opaque optionsABS and selected PP grades

Project logic
Make the process fit the product.
Draw depth and wall distribution
Material choice cannot compensate for impossible geometry. Draft, radii, plug assist and starting thickness all influence final wall distribution.
Secondary operations and compliance
Trimming, printing, bonding, sealing, food contact and recycled content can change the shortlist. Evaluate the complete production route before tool release.

Common questions
Details buyers ask before an RFQ.
Is PETG good for vacuum forming?+
Yes. PETG is commonly used for clear formed parts because of its toughness and forming behavior.
Can PVC be vacuum formed?+
Suitable PVC forming grades can be used for packaging and fabricated products when heat and ventilation are properly controlled.
How do I choose starting thickness?+
Starting thickness depends on finished wall requirement, draw ratio, tool geometry and material thinning. Forming simulation or trials may be needed.
