A Biodegradable Plastic Bag (PLA-Based) Manufacturing Unit is an eco friendly enterprise that produces compostable bags, shopping bags, garbage bags, and packaging materials using PLA, a biodegradable polymer derived from corn starch or sugarcane. The production process involves melting PLA pellets, extrusion into thin films, cutting, printing, and sealing to manufacture bags of various sizes and designs. PLA based bags are biodegradable, non toxic, heat sealable, and durable, making them ideal for retail stores, supermarkets, food packaging, e commerce packaging, and events. With increasing environmental awareness and government regulations against conventional plastics, demand for biodegradable bags is growing rapidly. The unit requires moderate investment in machinery such as extruders, film blowing machines, cutting and sealing machines, and printing units, along with skilled operators. By supplying eco friendly and certified biodegradable products, the unit can tap into both domestic and export markets, ensuring profitability while contributing to sustainable and environmentally responsible practices.
