Cov thawv ntim khoom pov tseg yog cov nkoj uas tsim los ntawm cov khoom siv xws li yas, ntawv, hmoov txhuv nplej siab, ntoo, thiab qee yam hlau, feem ntau yog siv rau ntim khoom noj.
Cov hom muaj xws li cov yas, ntawv, hmoov txhuv nplej siab, ntoo, thiab hlau. Polypropylene (PP) tau tshwm sim los ua cov khoom lag luam tseem ceeb vim nws cov khoom siv hluav taws xob siab, tsis yog - tshuaj lom neeg, muaj zog moldability, thiab cov nqi tsim khoom tsawg; Nws kuj tseem tsim nyog rau cov cua sov microwave, thiab cov khoom tsim los ntawm nws feem ntau dais daim duab peb sab "5" cim ntawm lawv lub hauv paus. Polystyrene (PS), thaum muaj siab rigidity, pom tsis zoo thaum tshav kub kub tsis kam; Nws feem ntau yog siv rau ntim cov khoom noj txias thiab cim nrog tus lej "6." Daim ntawv-raws li ntim, feem ntau coated nrog ib txheej polyethylene, tuaj yeem tiv taus qhov kub txog li 90℃tab sis feem ntau tsis haum rau microwave cua sov, hos aluminium foil ntim tau nruj me ntsis txwv tsis pub siv microwave vim lawv cov khoom siv hlau. Eco- lwm txoj hauv kev muaj txiaj ntsig muaj xws li cov thawv yas degradable thiab cov thawv ntim biodegradable tag nrho.
