Nta kaw galaw ai cling film hpe lusha hta shinggrup nna, lusha hta lawm ai sau ni gaw film kata na n kaja ai arung arai ni hpe n htum hkra n mai galaw ai. Microwave oven n galaw shi yang, lusha kaw na cling film hpe galoi mung shaw kau ra ai.
PP (polypropylene) - Mikrowave-shim lum ai! Mungkan ting na malu masha-madang Plastic Arung arai ni
PP arung arai gaw 130℃du hkra katsi ai hpe hkam jan lu nna 167℃du hkra hka lim ai shara nga ai . Dai tsi hpe steam hte sterilize galaw lu nna, acid hte alkali hpe ninghkap lu ai, chemical hpe ninghkap lu ai, shingjawng hkat lu ai akyu ni nga ai. Bai nna, Microwave- hta shim lum ai hte atsawm sha jasan jaseng ngut ai hpang bai lang mai ai plastic hka htung langai sha mung rai nga ai.

Kade nna ai aten hta, lang sha ai shat sha ku ni hta mung grai lang wa sai.
2. Foamed PS (Styrofoam ngu nna shamying ai) hpe galaw ai shaloi, foaming agent hpe lang nna, kalang 20 kaw nna 100 du hkra jat wa ai. Nta kata na arung arai ni (sh) shiga shapoi ai arung arai ni a matu cushioning packaging arung arai hku nna, shing nrai, ice cream box, nga box, etc. ni a matu heat-insulating arung arai hku nna lang ai.
PS arung arai hpe bowl- hkrang bung ai instant noodle box ni hte foam fast food box ni hpe galaw na matu lang chye ai. PS material gaw katsi ai-hpe hkam jan lu ai hte katsi ai- hpe hkam sharang lu ai raitim, katsi ai grai law ai shaloi chemical ni pru wa na re. Dai majaw, Microwave kata de galoi mung hkrak hkum bang! Bai nna, n-gun ja ai malu masha ni hpe pipe galaw na matu fast food hka htung ni hpe mung koi ga. Shinggyim hkum hkrang hpe hkra machyi shangun ai polystyrene hpe n-gun ja ai acid (orange juice zawn re ai) shing nrai n-gun ja ai alkaline ni hpe n mai hkam la ai.
PC arung arai ni hte kaga amyu bawsang ni - ndang kalang byin ai malu masha-grade Plastic arung arai ni
PC gaw grai lang ai arung arai langai rai nna, grau nna ma hkum hte space cup ni hta lang ai. Bisphenol A lawm ai majaw ndang kalang byin nga ai, nbung katsi ai shaloi, ngam ai bisphenol A grau law hkra pru wa nna, lawan ai hku pru wa ai. Dai majaw, hka lum ai hpe PC hka htung ni hta n mai bang da ai.
Chyum ninghkrin ni tsun ai raitim, PC galaw ai shaloi BPA hpe 100% plastic structure de galai shai kau ai shaloi, dai arai hta BPA n lawm ai, shapraw ai lam hpe tsun na pyi n ra ai ngu ai lachyum re.
