HTR & LTR PP Sheet for Thermoforming

High Temperature Resistant & Low Temperature Resistant PP Sheet is a specially formulated polypropylene sheet designed for thermoforming processes requiring wide temperature adaptability.

It maintains excellent dimensional stability, toughness, and formability under both high forming temperatures and low service temperatures, making it suitable for demanding industrial and packaging applications.

Compared with standard PP sheets, this material offers enhanced thermal resistance and impact performance, reducing cracking, warping, and forming defects during and after thermoforming.

Product Manager’s Insight (10+ Years in Thermoforming Industry)

“In real thermoforming production, the biggest problem is not forming — it’s stability.”

Many customers initially believe standard PP sheets are sufficient. However, after actual production runs, common issues appear:

• Sheets soften too fast at high temperatures, causing sagging
• Finished parts become brittle in cold storage
• Cracks occur during trimming or stacking
• Inconsistent wall thickness between batches

This High & Low Temperature Resistant PP Sheet was developed specifically to solve these real-world problems.

From a product manager’s perspective:

• This is not just a PP sheet, but a process-stable material
• It allows operators to run wider forming windows
• It reduces scrap rates, especially for thick or deep-draw parts
• It performs reliably in both hot-use and cold-use scenarios

For customers running continuous production lines, the reduction in downtime and rejected parts often outweighs the slight material premium.

If your products must survive both the forming oven and the cold chain, this is the PP sheet you should be using.
