Plastic bags are widely used globally. Even biodegradable plastic bags are available in diverse sizes and types on the market, catering to various carrying needs. According to China's national standards for biodegradable plastic bags, the key requirements mainly include the following three aspects:

1. General Classification

Different plastic bags vary in load-bearing capacity and application scenarios. A crucial classification criterion for biodegradable plastic bags, particularly from a food safety perspective, is specified in the national standards: clear labeling must be prominently displayed to distinguish between food-grade and non-food-grade biodegradable plastic bags.

2. Detailed Identification Requirements

Beyond general classification, those familiar with biodegradable plastic bags may notice the detailed specifications outlined in the standards. Per the latest national standards, biodegradable plastic bags must meet specific requirements regarding weight, material composition, model specifications, and labeling information.

3. Degradation Requirements

Biodegradable plastic bags must not only be designed and produced in compliance with national standards but also undergo degradation in accordance with specified criteria.

In practice, the complete biodegradation process of these plastic bags relies on biochemical reactions involving various microorganisms in the environment. The typical fermentation and degradation cycle is approximately six months. Compared with traditional plastic bags, the new generation of biodegradable plastic bags represents an upgraded, environmentally friendly alternative.
