Understand the definition of biodegradable plastic bags and contribute to environmental protection. As early as 2008, the United Nations called on people worldwide to reduce the use of plastic bags, yet their usage remains persistently high. Plastic bags not only pollute the atmosphere, oceans, and soil but also mar urban appearance. Currently, the Shanghai Municipal Government has announced a complete ban on providing plastic bags in supermarkets—even for purchase. However, some supermarkets offer free packaging supplies such as cartons, tape, and string.
When shopping, besides bringing your own plastic shopping bags, there are other alternatives. Nevertheless, certain supermarkets prohibit customers from bringing external bags into the store. While we reject traditional plastic bags, many residents opt for biodegradable plastic bags for convenience.
Biodegradable plastic bags primarily fall into two categories based on composition:
- Those that can be fully decomposed into water and carbon dioxide, typically made from materials like PBAT and PLA. These degradable materials are relatively expensive.
- Bio-based bags, composed mainly of ordinary starch and additives. To date, most so-called "degradable plastic bags" on the market cannot be fully and rapidly degraded in soil.
Beyond biodegradable plastic bags, the most environmentally friendly option available is biodegradable bags (fully plant-based). According to China's national standard GB/T for biodegradable plastic shopping bags, a biodegradable bag is defined as a shopping bag made from biodegradable plastics, used for carrying commodities in sales, service, and similar establishments. Its core components are PBAT and PLA, derived entirely from plant extracts with no plastic ingredients—making it highly beneficial for environmental protection.
Currently, there are few legitimate enterprises producing standard-compliant biodegradable plastic bags on the market, with many low-grade "degradable" plastic bags being passed off as high-quality biodegradable products. We recommend biodegradable plastic bags manufactured by Shenzhen Sayru Technology Co., Ltd.—a company specializing in eco-friendly biodegradable plastic products with professional manufacturing capabilities.
