How compostable bags are made

AMS•COMPOSTABLE bags are a sustainable alternative to traditional plastic bags, offering an eco-friendly solution for reducing plastic waste. These bags are made from materials that can break down into natural elements, leaving no toxic residue behind.

Raw Materials

The production process of compostable bags begins with the selection of suitable raw materials. These materials often include plant-based polymers such as cornstarch, sugarcane, or potato starch, which are renewable and biodegradable.

Extrusion

Once the raw materials are sourced, they undergo an extrusion process. The materials are melted and formed into thin, flexible sheets, which will serve as the base for the compostable bags.

Printing

After the extrusion process, the sheets may be printed with eco-friendly inks to add branding, logos, or other designs to the bags. This step allows for customization while maintaining the bags' compostable properties.

Bag Formation

The printed sheets are then cut and sealed to form the shape of the bags. This can be done using heat sealing or ultrasonic sealing techniques to create durable and reliable seams.

Quality Control

Before the bags are packaged for distribution, they undergo rigorous quality control measures to ensure that they meet industry standards for compostability and strength. This step is crucial in maintaining the integrity of the compostable bags.

Biodegradability Testing

Compostable bags are subjected to biodegradability testing to verify their ability to break down into natural elements within a specific timeframe. This testing ensures that the bags will decompose in a composting environment, leaving behind no harmful residues.

End-of-Life Disposal

Once in use, compostable bags can be disposed of in industrial composting facilities or home composting systems, where they will biodegrade into organic matter. This sustainable end-of-life disposal process contributes to reducing the environmental impact of plastic waste.

Conclusion

The production of compostable bags involves a series of carefully orchestrated steps, from raw material selection to end-of-life disposal considerations. By understanding how compostable bags are made, consumers can make informed choices to support sustainable and environmentally friendly alternatives to traditional plastic bags.
