1. Main material types
- PLA (Poly Lactic Acid)
- Source: Produced by fermentation of plants such as corn and sugar cane.
- Characteristics: Good heat resistance (typically can withstand 60-85℃), high transparency, suitable for cold and hot beverages as well as food containers.
- Degradation conditions: Decomposes in industrial composting environment (50-60℃, high humidity) within 6-12 months.
- PBAT (Polybutylene adipate-co-terephthalate)
- Characteristics: Good flexibility. It is often mixed with PLA to enhance heat resistance and strength, and is suitable for high-temperature cooked food.
- Degradability: Decomposes faster in soil or compost.
- Starch-based materials
- Source: Corn, potato and other plant starch mixed with other degradable materials.
- Characteristics: Low cost, but poor oil and water resistance, requires the addition of other materials to enhance performance.
- Paperboard Molded (Plant Fiber)
- Source: Sugarcane bagasse, bamboo pulp, etc.
- Characteristics: Naturally biodegradable. Usually coated with PLA or waterproof coating to enhance heat resistance (up to over 100℃).

2. Key Features
- Environmental friendliness: Through composting for degradation, it reduces plastic pollution (in line with international standards such as EN13432, ASTM D6400).
- Safety: Free of harmful substances like plasticizers and bisphenol A, suitable for direct contact with food.
- Functionality:
- High-temperature resistance (some products can reach above 120℃, suitable for microwave heating).
- Waterproof and oil-resistant (achieved through coating or material modification).
- Diversity: Can be made into lunch boxes, bowls, cups, trays, etc. Available in transparent or matte finishes.
