The Process of Making Compostable Mailers



The first step in making compostable mailing bags is blending the modified biopolymer with a color master batch to create a uniform mixture. Biopolymers like corn starch, PLA, and PBAT are used in the form of plastic beads.



The blended mixture is then melted in an extruder at temperatures ranging from 130-180°C. This process melts the biopolymer and makes it easier to mold into the desired shape.



After the biopolymer is melted, the air is pumped vertically through the film to create a tube-shaped film. The diameter of the tube is determined by the required width of the home compostable poly mailers.



The bioplastic tube is then cooled down slowly by passing through several rollers. This process forms sheets that eventually become compostable courier bags.



Most compostable shipping bags require printing with brand logos or other information. A simple 1-2 color logo can be printed while passing through rollers. However, complex patterns with more than 2 colors must be printed on a printing machine. Water-based ink is used for printing, which is also compostable, to ensure the end product is still eco-friendly.


Heat Sealing & Cutting

The compostable poly mailers are created by heat sealing and cutting the compostable film rolls. The heat sealing and cutting machine is set up according to the desired length of the bag, and the compostable film is rolled out to that length. Adhesive strips are being made at this stage. Once the required length is obtained, the machine cuts and seals the bag simultaneously. These bags can be designed in various shapes, depending on the purchaser’s needs or intended use.



After the cutting and sealing process, the bags are packed according to client requirements. The end product is ready to use and can be safely disposed of in a compost bin or other organic waste disposal methods, where it will decompose naturally without harming the environment.
