Plastarch Material (PSM) is a biodegradable, thermoplastic resin. It is composed of starch combined with several other biodegradable materials. The starch is modified in order to obtain heat-resistant properties, making PSM one of few bioplastics capable of withstanding high temperatures. PSM began to be commercially available in 2005.
Biodegradable polymers can be melt processed by conventional means such as compression or injection molding. Special consideration must be given to the need to exclude moisture from the material. Care must be taken to dry the polymers before processing to exclude humidity.
Boxed products made from bioplastics and other biodegradable plastics. Few commercial applications exist for bioplastics. Cost and performance remain problematic. Typical is the example of Italy, where biodegradable plastic bags are compulsory for shoppers since 2011 with the introduction of a specific law. [16]
Disposable plastic cups made from biodegradable plastic. Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. [1] Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all ...
Ingeo is also used in packaging and plastic bottles. [5] Its appearance can range from clear to opaque, and it can be flexible or rigid. The biopolymer is similar to polystyrene in exhibiting tensile strength and modulus comparable to hydrocarbon-based thermoplastics. Much like polyester, it resists grease and oil.
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting ), glasses , elastomers , confections , and most commonly ...
