Ndi zida ziti za pulasitiki zam'madzi zomwe zilibe BPA?

Bisphenol A (BPA) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri popanga zinthu zapulasitiki, monga PC (polycarbonate) ndi ma epoxy resins.Komabe, pamene nkhawa za kuopsa kwa thanzi la BPA zawonjezeka, opanga zinthu zapulasitiki zina ayamba kufunafuna njira zina zopangira zinthu zopanda BPA.Nazi zina mwazinthu zapulasitiki zomwe nthawi zambiri zimatsatiridwa ngati BPA-free:

1. Tritan™:

Tritan™ ndi pulasitiki yapadera ya copolyester yomwe imagulitsidwa ngati BPA-free pomwe ikupereka kuwonekera kwambiri, kukana kutentha komanso kulimba.Zotsatira zake, zinthu za Tritan™ zimagwiritsidwa ntchito m'zakudya zambiri, magalasi akumwa, ndi zinthu zina zolimba.

2. PP (polypropylene):

Polypropylene nthawi zambiri imadziwika kuti ndi pulasitiki yopanda BPA ndipo imagwiritsidwa ntchito kwambiri m'zakudya, mabokosi azakudya a microwave ndi zinthu zina zolumikizirana ndi chakudya.

3. HDPE (polyethylene yochuluka kwambiri) ndi LDPE (polyethylene yotsika kwambiri):

High-density polyethylene (HDPE) ndi low-density polyethylene (LDPE) nthawi zambiri amakhala opanda BPA ndipo amagwiritsidwa ntchito popanga mafilimu oyika zakudya, matumba apulasitiki, ndi zina zambiri.

4. PET (polyethylene terephthalate):

Polyethylene terephthalate (PET) imatengedwanso kuti alibe BPA ndipo imagwiritsidwa ntchito popanga mabotolo omveka bwino a zakumwa ndi kulongedza zakudya.

Ndikofunikira kudziwa kuti ngakhale zida zapulasitikizi zimalengezedwa ngati zopanda BPA, nthawi zina zowonjezera kapena mankhwala ena amatha kupezeka.Chifukwa chake, ngati mukukhudzidwa kwambiri ndi kupewa kukhudzana ndi BPA, ndibwino kuyang'ana zinthu zolembedwa ndi logo ya "BPA Yaulere" ndikuwonetsetsa zomwe zapakidwa kapena zida zotsatsira kuti mutsimikizire.
