What food standards must PLA cold drink cups meet during production?

PLA beverage cups, as environmentally friendly packaging that comes into direct contact with food, must be manufactured in strict accordance with national food safety standards. Compliance throughout the entire process, from raw materials and production to testing, is essential to ensure safe use.

The core mandatory standard is GB 4806.7-2023, "National Food Safety Standard - Plastic Materials and Products for Food Contact," which covers key aspects such as raw materials, additives, and physicochemical indicators. Raw materials must use food-grade PLA resin that meets national standard resin requirements; additives must strictly adhere to GB 9685 standards, prohibiting the use of illegal additives and preventing the migration of harmful substances.

Physicochemical testing is crucial for compliance. Tests must be passed for total migration, potassium permanganate consumption, and heavy metal limits to ensure the soaking solution is free of turbidity, discoloration, and odor, meeting the minimum safety requirements for food contact. Simultaneously, it must comply with the general requirements of GB/T 18006.1 for disposable tableware, balancing appearance, strength, and performance to suit cold beverage serving scenarios.

Compliant production is not only an industry baseline but also the foundation of brand trust. PLA cold beverage cups can only enter catering and retail channels after passing comprehensive testing and with clear labeling, providing consumers with a safe and reliable green choice.
