Cov thawv ntim yas yog ib puag ncig tus phooj ywg ntim ntim tshuaj molded feem ntau los ntawm polyethylene (PE), polypropylene (PP), thiab acrylonitrile-butadiene-styrene copolymer (ABS). HDPE, vim nws qhov yooj yim thiab tawv, feem ntau yog siv los khaws cov khaub ncaws hauv tsev.
Kev tsim kho tshiab ntawm cov ntaub ntawv yog lub hauv paus tseem ceeb rau kev txhim kho kev lag luam, nrog kev nce ntxiv hauv kev siv cov yas biodegradable, rov siv dua polypropylene (PP), thiab siab - cov ntaub ntawv muaj zog. Biodegradable plastics xws li PLA thiab PBAT tau raug siv, thiab rov siv dua polypropylene (PP) granules, tom qab siv tshuaj lom neeg, muaj cov khoom mus txog cov ntaub ntawv nkauj xwb. Bio-raws li plastics, los ntawm kev hloov kho nanotechnology, ua kom luv luv lawv lub voj voog degradation thaum tuav cov load-cov kabmob muaj peev xwm.
Lub hauv paus ntawm lub thawv yas kev lag luam saw hlau yog tsim los ntawm cov chaw muag khoom ntawm cov khoom siv yooj yim xws li polyethylene (PE) thiab polypropylene (PP), thiab cov txheej txheem kev lag luam ntawm bio-raws li thiab biodegradable cov ntaub ntawv yog nrawm.
