Production of new starch-based eco-friendly material for bags.
The production of starch-based bags is an environmentally friendly alternative to plastic products and consists of several key stages.
Here is the process scheme
-
Raw Material Preparation
-
Starch (typically derived from corn, potatoes, or other plants) is the main raw material.
-
It is cleaned, milled, and prepared for further processing.
-
Often, biodegradable additives are added to improve flexibility and strength.
-
Starch Hydrolysis
-
Hydrolysis breaks down the long chains of starch molecules into shorter ones (dextrins), improving plasticity and ease of processing.
-
This is achieved by using enzymes or acids to alter the molecular structure.
-
Polymerization and Granulation
-
The hydrolyzed starch is mixed with additives and then undergoes polymerization (a process that turns starch into a biodegradable polymer).
-
The resulting mass is cooled and formed into granules – the bioplastic material.
-
Extrusion and Shaping
-
Granules are loaded into an extruder – equipment that melts the bioplastic and shapes it.
-
The extruded material can be turned into film, which is then cut and welded to create bags.
-
Final Processing and Packaging
-
Finished bags can be printed with logos and other information.
-
The bags are packaged and prepared for shipment.
