The innovation in material science for cookie trays at Zhejiang Hengiiang Plastic Co., Ltd. involves exploring new polymers and composites to enhance performance and sustainability. Research focuses on materials like PET-G for improved formability or bio-PP from renewable sources, which reduce environmental impact. The automatic sheet making machines are adapted to handle thesenew material, ensuring consistent quality. In application scenarios, such as for high-barrier requirements, the company has developed multi-layer trays that combine PET and EVOH for superior oxygen protection, extending cookie shelf life by up to 30%. A case study with a health-conscious brand used these trays for organic cookies, resulting in reduced food waste. The GMP clean workshop facilitates trials with new materials under controlled conditions. The laboratory conducts accelerated aging tests to predict long-term behavior. The technical managers partner with academic institutions to stay at the forefront of material innovations. With a building area of 13,000 m², dedicated areas for material testing support this R&D, while the storage area holds experimental batches. This commitment to material advancement ensures that Hengiiang's cookie trays remain competitive and future-ready.
