Bisphenol A (BPA) yog cov tshuaj uas siv dav hauv kev tsim cov khoom yas, xws li PC (polycarbonate) thiab qee cov epoxy resins.Txawm li cas los xij, raws li kev txhawj xeeb txog kev pheej hmoo ntawm kev noj qab haus huv ntawm BPA tau nce ntxiv, qee cov khoom lag luam yas tau pib nrhiav lwm txoj hauv kev los tsim cov khoom tsis muaj BPA.Nov yog qee cov ntaub ntawv yas uas feem ntau tshaj tawm tias tsis muaj BPA:
1. Tritan ™:
Tritan ™ yog cov khoom siv tshwj xeeb copolyester yas uas yog muag raws li BPA-dawb thaum muab cov pob tshab siab, ua haujlwm kub thiab ua haujlwm ntev.Vim li ntawd, cov khoom siv Tritan ™ yog siv rau hauv ntau lub thawv ntim khoom noj, iav haus, thiab lwm yam khoom siv ruaj khov.
2. PP (polypropylene):
Polypropylene feem ntau suav hais tias yog cov khoom siv yas tsis muaj BPA thiab tau siv dav hauv cov thawv ntim khoom noj, lub thawv khoom noj microwave thiab lwm yam khoom noj khoom haus.
3. HDPE (siab ceev polyethylene) thiab LDPE (tsawg ntom polyethylene):
High-density polyethylene (HDPE) thiab low-density polyethylene (LDPE) feem ntau yog BPA-dawb thiab feem ntau yog siv los ua cov hnab ntim zaub mov, hnab yas, thiab lwm yam.
4. PET (polyethylene terephthalate):
Polyethylene terephthalate (PET) kuj tseem suav tias yog BPA-dawb thiab yog li siv los tsim cov raj mis dej ntshiab thiab ntim khoom noj.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum cov ntaub ntawv yas no feem ntau tau tshaj tawm tias tsis muaj BPA, qee zaum muaj lwm yam tshuaj ntxiv lossis tshuaj lom neeg.Yog li ntawd, yog tias koj muaj kev txhawj xeeb tshwj xeeb txog kev zam kom tsis txhob raug BPA, nws yog qhov zoo tshaj los nrhiav cov khoom uas cim nrog "BPA Dawb" logo thiab xyuas cov khoom ntim lossis cov ntaub ntawv tshaj tawm kom paub meej.
