PLA Straws are more environmentally friendly

Posted By pando cup     August 5, 2021    


With the continuous development of the social economy and the continuous growth of the global population, the earth’s resources have been severely exploited, and environmental and energy problems such as global warming and the depletion of oil resources have become more and more severe. Among them, polymer compounds synthesized from petroleum and other resources are used in The pollution to the environment in the process of production, consumption, and abandonment has become increasingly prominent, and people have realized the importance of protecting the environment.

Therefore, in recent years, non-petroleum-based degradable materials have attracted more and more attention. Among the many biodegradable materials, PLA, as a new type of environmentally friendly polymer material, has gradually attracted people's attention.

Characteristics of PLA material:

1. Biodegradability

Compared with traditional plastics, polylactic acid can be degraded into CO2 and H2O by microorganisms and light. Its degradation products are non-toxic and harmless, and will not pollute the environment. The monomer for the production of polylactic acid is lactic acid, and lactic acid can be produced by fermentation of crops or agricultural by-products such as wheat, rice and sugar beet. Therefore, the raw materials for the production of polylactic acid are renewable. As an emerging biodegradable material, polylactic acid has a wide range of applications.

2. Biocompatibility and absorbability

Polylactic acid can be hydrolyzed by acid or enzyme to produce lactic acid in the human body. As a metabolite of cells, lactic acid can be further metabolized by enzymes in the body to produce CO2 and H2O. Therefore, polylactic acid is non-toxic and harmless to the human body and has good biocompatibility and absorbability. Polylactic acid has passed the certification of the US Food and Drug Administration and can be used as a biological material implanted in the human body.

3. Physical processability

As a thermoplastic polymer material, polylactic acid has good plasticity and physical processing properties, high melting point and crystallinity, good elasticity and flexibility, and excellent thermoformability. Polylactic acid materials, like polypropylene (PP), polystyrene (PS), and polyphenylene ether resin (PPO), can be extruded, stretched, and injection blow molded, and other high-molecular materials can be processed.

Compostable PLA Straw is made of a new type of bio-based and renewable biodegradable material, this material is called PLA, also known as polylactic acid. It is made of starch raw materials proposed by renewable plant resources (such as corn, cassava, etc.) and is degradable. Ordinary plastic straws are not degradable.
