As the food delivery economy booms, disposable lunch boxes have become a major source of "white pollution." Linyi Shengtu Degradable Supply Chain Co., Ltd. is tackling this head-on with a mission: to live for the planet. Leveraging self-developed PLA fully degradable material technology, we've created lunch boxes that are safe, practical, and eco-friendly — powering the green transformation of the food service industry.
🌱 Raw Material Control
Linyi Shengtu breaks free from petroleum-dependent plastics. We focus on PLA modification and upgrading — selecting PLA base pellets made from renewable crops like corn and cassava, then applying our proprietary bio-compatible modification process to optimize mechanical performance and processability, perfectly tailored for lunch box production.
♻️ Truly Degradable
After use, Linyi Shengtu's PLA lunch boxes break down into just water and CO₂ — no toxic residue left in soil or water. Degradation takes only 3–12 months, a dramatic improvement over hundreds of years for conventional plastics.
🍽️ Wide-Ranging Applications
Linyi Shengtu's PLA degradable materials are now deeply integrated into diverse scenarios. For restaurants, our lunch boxes help meet "plastic ban" regulations while boosting brand image with an eco-friendly label — attracting younger, sustainability-conscious consumers.
💪 Breakthroughs That Matter
1️⃣ Early PLA materials were brittle at low temperatures and lacked heat resistance. We've changed that — making "eco-friendly" and "high-performance" no longer contradictory.
2️⃣ Linyi Shengtu assembled a dedicated R&D team to tackle this challenge. Through molecular structure modification, we significantly enhanced tensile strength and toughness — so the lunch boxes stay intact even during bumpy deliveries, preventing spills and leaks.
3️⃣ Our unique blending process and precision calendering technology deliver excellent sealing and heat resistance.
4️⃣ Tested by authoritative third-party agencies, our lunch boxes far exceed national standards for heavy metal content and food-contact safety. We've earned EU EN13432 and US ASTM D6400 international certifications — meeting the strictest requirements in global markets.
🌏 For the Planet, For the People
Consumers can use our lunch boxes with confidence — no plastic residue worries, safe for heating and holding all types of food. Eco-friendly packaging protects the Earth while meeting the demand for convenient living. It's a true win-win of ecological benefit and market value.
