Corn starch has 25% amylose and 75% amylopectin. The amylose molecules loose lose water increase biodegradation characteristic and amylopectin molecule is responsible for plasticizer properties. Their granule size ranges between 5 to 20 microns. Good absorption capacity, rapid gel formation & good strength.

Two types of bioplastics are now produced in large quantities. They are called polylactide acid (PLA) and polyhydroxyalkanoate (PHA). The PLA formation is done from corn kernels are milled and a chemical substance called dextrose is extracted, and dextrose is fermented by bacteria or yeast in big vats. The result is lactic acid, which acts as a repeating unit to make PLA.
Polymer, that are cheaper and lighter than many materials, are being favored for industrial and commercial applications. Plastics are necessary in daily life experience, using them in household appliances, cars, packages ex. One of three of plastic raw materials being used by package sector. The main environmental problem of conventional plastics are, degrading in nature for centuries and produced by nonrenewal natural sources like petroleum, coal and natural gas. Today, being recycling and environmentally friendly facilities come into prominence for plastics.
Uses and Application
Bio-plastics are used for disposable items, such as packaging, crockery, cutlery, pots, bowls, and straws. They are also often used for bags, trays, fruit and vegetable containers and blister foils, egg cartons, meat packaging, vegetables, and bottling for soft drinks and dairy products.
These plastics are also used in non-disposable applications including mobile phone casings, carpet fibers, insulation car interiors, fuel lines, and plastic piping. New electro active bio plastics are being developed that can be used to carry electric current. In these areas, the goal is not biodegradability, but to create items from sustainable resources.
Advantages & Disadvantages of Biodegradable Plastic Products
1. Biodegradable plastics take less time to break down.
2. Biodegradable plastics are renewable.
3. Biodegradable plastics are good for the environment.
4. Biodegradable plastics require less energy to produce.
5. Biodegradable plastics are easier to recycle.
6. Biodegradable plastics are not toxic.
7. Biodegradable plastics reduce dependence on fossil oil.
Types of Biodegradable Bags
Type 1: The original biodegradable bags, still found today, are made from pellets containing starches, polyethylene, and heavy metals such as cadmium, lead, and beryllium.
Type 2: A second type has been invented using starches combined with biodegradable polymers such as PLA or BASF.
Type 3: Oxo-Biodegradable bags use Totally Degradable Plastics Additives (TDPAt) to stimulate the breakdown of polymers and thus speed up the biodegradation process of Conventional plastics.
Market Outlook
The biodegradable plastics market is segmented into five major applications, namely, packaging, fibers, agriculture, injection molding, and others. The demand for biodegradable plastics in injection molding application is expected to witness the fastest growth among all the applications. Biodegradable plastics demand is predicted to increase in emerging BRICS economies over the foreseeable future owing to increasing food & beverage and electronic packaging industries in these countries. Changing lifestyle pattern coupled with increasing packaged food products demand is expected to drive food beverages industry. This in turn is anticipated to increase biodegradable paper and plastics packaging demand in Asia Pacific region in near future. Growing pharmaceuticals packaging industry in Asia Pacific region is anticipated to propel market growth. Technological advancement in distribution channels coupled with advanced manufacturing processes is expected to augment biodegradable paper and plastics market growth in the region.
