From Corn to Compostable Bags: How Our Bags Are Made？
At Torise Biomaterials, we turn inedible corn into 100% compostable bags. Using advanced technology, we convert corn starch into PLA (polylactic acid), a biodegradable material that breaks down into water and CO2 in just 180 days under industrial composting conditions. Our bags are DINplus and EN13432 (Din Certco), OK Compost, OK Compost HOME (TUV Austria), ASTM D6400 (BPI), AS4736 and AS5810 (ABA) certified, ensuring they meet the highest global sustainability standards.
Corn's Journey: From Farm to Bag
●Step 1: Starch Extraction
Corn kernels are broken down to extract starch, which contains long-chain carbon molecules similar to those in petroleum-based plastics.
●Step 2: Fermentation and Polymerization
The starch is fermented into lactic acid, which is then polymerized into PLA—a strong, flexible, and fully biodegradable material.
●Step 3: Resin Modification
PLA is mixed with other bio-based materials, such as PBAT, to form a modified resin, which is then used to produce durable, environmentally friendly bags.
Precision Production: Quality You Can Trust
Our advanced manufacturing processes ensure that every bag meets the highest standards:
●Pelletizing: The resin is melted and formed into uniform pellets to maintain consistency.
●Film Blowing: The pellets are blown into a thin, strong film with a thickness tolerance of less than 0.01 mm.
●Bag Making: Cutting the film, printing (using water-based inks).
Quality Control:
●Raw materials are tested for melt index, carboxyl content and color uniformity.
●Bags are rigorously tested (tensile strength, tear resistance, dart impact) to ensure durability.
●Defective bags are recycled into pellets, resulting in zero waste.
