How to produce compostable trash bags?

As a professional compostable bags manufacturer. Let me tell you how to produce compostable trash bags. Producing compostable trash bags requires a specific process and materials that are designed to break down into natural materials, such as carbon dioxide, water, and organic matter, under specific conditions, such as high temperatures, moisture, and oxygen. Here are the general steps involved in producing compostable trash bags:

1. Choose the raw materials: Compostable trash bags are often made from plant-based materials, such as cornstarch, PBAT and PLA, which are renewable, biodegradable, and non-toxic. The raw materials should be sourced from sustainable and certified suppliers to ensure their quality and traceability.

2. Mix and extrude the materials: The raw materials are mixed with other additives, such as plasticizers, pigments, and stabilizers, to create a homogenous and flexible blend. The blend is then extruded into a thin film through a process called blown film extrusion, which stretches and cools the material into a flat and continuous sheet.

3. Print and convert the bags: The flat sheet is then printed with the desired design or information and converted into bags through a process called bag making. The bags can be customized in terms of size, thickness, shape, and closure, depending on the requirements and preferences of the customers.

4. Test and certify the bags: The compostable trash bags should be tested and certified by reputable standards, such as ASTM D6400 or EN 13432, to ensure their compostability and biodegradability. The bags should also meet other criteria, such as tensile strength, puncture resistance, and shelf life, to ensure their functionality and durability.

Producing compostable trash bags can be a complex and regulated process that requires expertise, technology, and compliance with environmental and social standards. It’s important to work with reputable and certified suppliers and manufacturers, and to ensure transparency and accountability throughout the supply chain.
