The production process for biodegradable corn starch mailing bags typically involves the following steps: Raw material sourcing: The main raw material for these bags is corn starch, which is sourced from corn crops. Extraction of starch: The corn kernels are processed to extract the starch, which is then dried and milled into a fine powder. Blending: The corn starch powder is blended with other biodegradable materials, such as cassava or potato starch, to improve the strength and durability of the final product. Melting and extrusion: The blended mixture is melted and then extruded through a die to form a continuous film. Cooling and cutting: The film is cooled and then cut into the desired size and shape to create individual bags. Printing: The bags can be printed with branding or product information using eco-friendly inks. Quality control: Before packaging and shipment, the bags undergo a thorough quality control process to ensure they meet the necessary standards for strength and biodegradability. Packaging and shipment: The final bags are packaged and shipped to customers, ready to be used as a sustainable packaging solution.
