Cov tais diav pov tseg tuaj yeem muab faib ua peb pawg hauv qab no raws li cov khoom siv raw, txheej txheem tsim khoom, hom degradation thiab qib rov qab:
1. Biodegradation: xws li cov khoom siv ntawv (xws li pulp molding, paperboard coating), edible hmoov molding, cog fiber ntau molding, thiab lwm yam.
2. Diam duab / biodegradable cov ntaub ntawv: photobiodegradable plastics (tsis foaming), xws li photodegradable PP
3. Ib qho yooj yim rau cov ntaub ntawv rov ua dua: xws li polypropylene (PP), siab cuam tshuam polystyrene (HIPS), biaxial tensile polystyrene (BOPS), ntuj inorganic ntxhia ntim cov khoom siv polypropylene composite.
Cov riam thiab rab diav rawg pov tseg feem ntau yog ua los ntawm polypropylene (PP), polyethylene (PE) thiab lwm yam ntaub ntawv.
