RPET Clear Rigid Sheet For Clamshell Thermoforming
RPET Clear Rigid Sheet For Clamshell Thermoforming is a sustainable, high-clarity packaging material manufactured from post-consumer recycled PET (RPET) content. This rigid sheet is specifically engineered for thermoforming applications, delivering the optical clarity and mechanical performance of virgin PET while significantly reducing environmental impact. The sheet is ideal for producing durable, transparent clamshell packaging for consumer goods, electronics, hardware, and retail products.
The use of RPET in this sheet does not compromise quality-advanced recycling and decontamination processes ensure the material meets food-contact and consumer safety standards. The sheet offers excellent gloss, low haze, and consistent formability, making it a drop-in replacement for virgin PET on existing thermoforming lines.
Key Sustainability Credentials:
Contains up to 100% post-consumer recycled content (grade dependent)
Reduces carbon footprint by 30–50% compared to virgin PET
100% recyclable (#1 PET) at end of life
FDA-compliant for food contact (specific RPET grades)
Applications: Clamshell packaging for electronics, toys, hardware, cosmetics, fresh produce, and bakery items.

FAQ – RPET Clamshell Focus
Q1: What percentage of recycled content does this sheet contain?
We offer grades from 30% to 100% post-consumer recycled content. Specify your target percentage at order. Higher recycled content may slightly affect clarity-we recommend testing a sample first.
Q2: Is RPET as clear as virgin PET?
Yes-with advanced recycling technology, high-quality RPET achieves clarity comparable to virgin PET. Haze <5% is achievable with our optimized formulation.
Q3: Can RPET be used for food contact packaging?
Yes-FDA-approved RPET grades are available for direct food contact. The recycling process ensures contaminants are removed to safe levels.
Q4: Does RPET affect thermoforming performance?
No-RPET behaves identically to virgin PET on thermoforming lines. No machine modifications needed.
Q5: Is the sheet recyclable after use?
Yes-RPET clamshells are #1 PET and widely accepted in municipal recycling programs.
Q6: What is the shelf life of the sheet itself?
18 months when stored at 15–25°C, <60% RH, away from direct sunlight.
Q7: What is the minimum order for a trial?
Sample sheets (10 A4): free + courier. Sample roll (50kg): $250 + shipping. Trial roll (200kg): 7 working days. Commercial MOQ: 500kg.
