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. I.e. good absorption capacity, rapid gel formation & good strength. Starch is used to supply such diverse products as food, paper, textiles, adhesives, beverages, confectionery, packaging, pharmaceuticals, and building materials. Cassava starch has many remarkable characteristics, including high paste viscosity, high paste clarity, and high freeze-thaw stability, which are advantageous to many industries.
Cassava starch might be used for creating various varieties of packaging products. As a major source of starch in tropical and subtropical regions, cassava may be a promising staple for the event of biodegradable plastics in these areas. Biodegradable packaging sector may be a small segment which represents a merger percentage of the packaging industry. The worldwide biodegradable packaging has now moved on towards more advanced and efficient packaging. A decade ago, biodegradable packaging wasn't known to possess any real significance. However, recently biodegradable packaging has become an integral a part of the worldwide packaging market. The rising consumer awareness towards biodegradable packaging has led to the tremendous growth of the overall market.
Cassava bags are made by making PLA(Poly(lactic acid) or polylactic acid or polylactide (PLA) is a biodegradable and bioactive thermoplastic aliphatic polyester derived from renewable biomass, typically from fermented plant starch such as from corn, cassava, sugarcane or sugar beet pulp). These PLA resins (granules) are then added to a machine (film blower machine) and make the bio plastic sheets, then these bioplastics sheets are feeded into bag making machine and cut bags.
The global biodegradable plastic packaging market was valued at USD 4.65 billion in 2019, and is expected to reach a market value of USD 12.06 billion by 2025, registering a CAGR of 17.04% during the forecast period of 2020-2025.Growing environmental concerns regarding plastic usage that consists of toxic pollutants which are harming plants, animals, and people are driving the use of biodegradable plastic. Stringent regulations by various government and federal agencies with an objective to reduce plastic waste and promote biodegradable plastics usage in packaging is boosting the demand of this market. Regulations related to green packaging is increasing and various FMCG companies are required to adopt biodegradable packaging to comply with the standards which in turn is propelling the growth of this market.
