Jiangyin Film-maker Plastic Co., Ltd is pleased to announce the launch of its newly developed PLA grade SPL 701, marking another milestone in the company’s innovation roadmap for sustainable and bio-based polymer materials.

PLA SPL 701 is a medium-to-high-gloss homopolymer of pure Poly-L-Lactic Acid, synthesised from L-lactide with an optical purity of more than 98%. The material features a melting point ≥160°C, offering enhanced heat resistance while maintaining excellent transparency and optical performance. These characteristics make SPL 701 particularly suitable for products that require both clarity and thermal stability.
