1.Polyethylene Terephthalate (PET lossis PETE)
Qhov no yog ib qho ntawm feem ntau siv plastics.Nws yog lub teeb yuag, muaj zog, feem ntau yog pob tshab thiab feem ntau siv hauv ntim khoom noj thiab cov ntaub (polyester).
Piv txwv li: lub raj mis dej haus, cov khoom noj fwj / jars (salad dressing, txiv laum huab xeeb, zib ntab, thiab lwm yam) thiab polyester khaub ncaws los yog hlua.
2.High-Density Polyethylene (HDPE)
Sib sau ua ke, Polyethylene yog cov yas ntau tshaj plaws hauv ntiaj teb, tab sis nws tau muab faib ua peb hom: High-Density, Low-Density thiab Linear Low-Density.High-Density Polyethylene muaj zog thiab tiv taus cov dej noo thiab tshuaj, uas ua rau nws zoo tagnrho rau cov thawv, ntim, kav dej thiab lwm yam khoom siv hauv tsev.
Piv txwv li: mis nyuj cartons, detergent fwj, cereal box liners, khoom ua si, thoob, chaw ua si lub rooj zaum thiab cov kav dej khov.
3.Polyvinyl Chloride (PVC lossis Vinyl)
Cov yas tawv thiab tawv tawv no tiv taus cov tshuaj lom neeg thiab huab cua, ua rau nws xav tau rau kev tsim kho thiab kev siv;thaum qhov tseeb tias nws tsis ua hluav taws xob ua rau nws siv rau kev siv high-tech, xws li xov hlau thiab cable.Nws kuj tseem siv dav hauv daim ntawv thov kev kho mob vim tias nws tsis tuaj yeem nkag mus rau cov kab mob, yog yooj yim tua kab mob thiab muab cov ntawv siv ib zaug uas txo cov kab mob hauv kev kho mob.Nyob rau sab ntxeev, peb yuav tsum nco ntsoov tias PVC yog cov yas txaus ntshai tshaj plaws rau tib neeg kev noj qab haus huv, paub tias yuav tshem tawm cov co toxins txaus ntshai thoob plaws hauv nws lub neej tag nrho (xws li: lead, dioxins, vinyl chloride).
Piv txwv li: Cov kav dej kav dej, daim npav rho nyiaj, tib neeg thiab tsiaj cov khoom ua si, cov kav dej nag, cov hniav sib tsoo, cov hnab ntim dej IV thiab cov raj kho mob thiab cov npog ntsej muag oxygen.
4.Low-Density Polyethylene (LDPE)
Lub softer, clearer, thiab saj zawg zog version ntawm HDPE.Nws feem ntau yog siv los ua ib lub liner hauv cov thawv dej haus, thiab hauv cov chaw ua haujlwm corrosion-resistant thiab lwm yam khoom.
Piv txwv: Yas / cling qhwv, qhaub cij thiab khob cij, npuas qhwv, hnab khib nyiab, hnab khoom noj thiab khob dej haus.
5.Polypropylene (PP)
Qhov no yog ib qho ntawm cov khoom siv ruaj khov tshaj plaws ntawm cov yas.Nws yog cov cua sov tiv taus ntau dua li lwm tus, uas ua rau nws zoo tagnrho rau cov khoom ntim khoom noj thiab cov khoom noj khoom haus uas tau ua los tuav cov khoom kub lossis kub nws tus kheej.Nws yooj yim txaus los tso cai rau me ntsis khoov, tab sis nws khaws nws cov duab thiab lub zog rau lub sijhawm ntev.
Piv txwv li: Straws, lub kaus mom lub raj mis, lub raj mis tshuaj, cov thawv ntim khoom noj kub, ntim daim kab xev, cov ntaub so ntswg pov tseg thiab lub thawv DVD / CD (nco txog cov ntawd!).
6.Polystyrene (PS lossis Styrofoam)
Zoo dua lub npe hu ua Styrofoam, cov yas nruj no yog tus nqi qis thiab insulates zoo heev, uas tau ua rau nws cov khoom noj khoom haus, ntim khoom thiab kev lag luam.Zoo li PVC, polystyrene raug suav tias yog cov yas txaus ntshai.Nws tuaj yeem yooj yim tshem tawm cov co toxins xws li styrene (ib qho neurotoxin), uas tuaj yeem yooj yim nqus los ntawm cov zaub mov thiab yog li noj los ntawm tib neeg.
Piv txwv li: khob khob, ntim khoom noj khoom haus, shipping thiab ntim khoom, qe cartons, cutlery thiab lub tsev rwb thaiv tsev.
7.Lwm yam
Ah yog, qhov tsis zoo "lwm yam" kev xaiv!Pawg no yog ib tug catch-tag nrho rau lwm hom yas uas tsis muaj nyob rau hauv ib yam ntawm lwm yam rau rau pawg los yog ua ke ntawm ntau hom.Peb suav nrog nws vim qee zaus koj tuaj yeem hla # 7 cov lej rov ua dua tshiab, yog li nws tseem ceeb kom paub tias nws txhais li cas.Qhov tseem ceeb tshaj plaws ntawm no yog cov plastics no feem ntau tsis tuaj yeem rov ua dua tshiab.
Piv txwv li: tsom iav qhov muag, lub raj mis me nyuam mos thiab cov kis las, khoom siv hluav taws xob, CD/DVDs, teeb pom kev zoo thiab cov khoom siv yas yas.
