Biodegradable PLA Challenge PET

Corn-based biodegradable plastic polylactic acid (PLA) NatureWorks (trade name) is less expensive than existing materials PET in some applications. According to a Belgian company, packaging using PLA as a raw material saves 68% more than PET, and now that oil prices have risen, PLA has been able to compete with PET in recent months and will be able to compete with PS in the next few years. competition. The PS price is very unstable, and existing NatureWords has competed with the PS in many areas for the market. Delhaize, a Belgian retailer, started using NatureWorks' fresh salad boxes in September 2005 and is evaluating the use of this material for bread, fruit and vegetables. The company stated that although the PLA costs slightly higher than before, it promised to keep the price unchanged for customers. French chain retailer Auchan has introduced more than 6 million fresh food containers made of PLA, because PLA has more competitive advantages than PET. By the end of December 2005, 25 million cakes and PET cakes had been packaged in PLA before the end of December 2005.
