# Common Materials Used in Plastic Cup Thermoforming Machines

2026.06.301 min read****HENGFENG Engineering Team****

PP, PET, PS, HIPS, PLA and PE — how to choose the right sheet material for your cup program.

Choosing the right material is the first decision in any cup thermoforming project.

**PP** offers the best balance of heat resistance and cost for hot-drink and food cups. **PET** delivers glass-like clarity for cold beverage cups. **PS / HIPS** remain economical choices for dairy and portion cups. **PLA** serves compostable, eco-positioned product lines.

HENGFENG tilting cup machines and multistation formers process all of the above; our sheet extrusion lines can produce the matching sheet in-house, closing the material loop with in-line crushers.
