Polyethylene (PE) plastiki, chinhu chinowanzo shandiswa pakurongedza chikafu, yakawana kutariswa kwekuita kwayo uye kuchengetedza. PE plastiki ipolymer inoumbwa ne ethylene units, inozivikanwa nekugadzikana kwayo uye isina-reactivity. Izvi zvivakwa zvinoita kuti PE ive sarudzo yakanaka yekudya-giredhi application, sezvo isingaburitse makemikari anokuvadza muchikafu, kunyangwe kana akaiswa kune akasiyana tembiricha.
Safety Studies uye Regulations
Tsvagiridzo yakadzika uye mirau yakaomesesa inovimbisa kuti chikafu-giredhi PE plastiki yakachengeteka pakubata chikafu. Zvidzidzo zvakaratidza kuti PE plastiki haiburitse zvinhu zvinokuvadza pasi pemamiriro ekushandiswa akajairwa. Mitumbi inodzora seUS Food and Drug Administration (FDA) neEuropean Food Safety Authority (EFSA) yakagadzira mirau uye zviyero izvo PE plastiki inofanirwa kusangana kuti ionekwe sechikafu-giredhi. Aya mazinga anosanganisira kuyedzwa kwekufamba kwemakemikari, kuve nechokwadi chekuti chero kutamiswa kwezvinhu kubva mupurasitiki kuenda kuchikafu kunoramba kuri mukati memiganhu yakachengeteka.
Zvakajairwa Zvishandiso muChikafu Packaging
PE plastiki inoshandiswa zvakanyanya mumhando dzakasiyana dzekurongedza chikafu, kusanganisiraPE mabhegi, zipper bags,uyeziplock bags. Aya ekurongedza mhinduro anopa yakanakisa kunyorova kuramba, kuchinjika, uye kusimba, zvichiita kuti ive yakakodzera kuchengetedza zvakasiyana-siyana zvechikafu zvigadzirwa. Mabhegi ePE, semuenzaniso, anowanzo shandiswa kugadzirwa kutsva, svutugadzike, uye chikafu chakaomeswa nekuda kwekugona kwavo kuchengetedza kutsva uye kuwedzera hupenyu hwesherufu.
Kuenzanisa nemamwe Plastics
Kuenzaniswa nemamwe mapurasitiki, akadai sepolyvinyl chloride (PVC) uye polystyrene (PS), PE plastiki inoonekwa seyakachengeteka uye ine hushamwari hwakatipoteredza. PVC, semuenzaniso, inogona kuburitsa makemikari anokuvadza senge phthalates uye dioxins, kunyanya kana inopisa. Kusiyana neizvi, PE plastiki yakapusa chimiro chemakemikari uye kugadzikana kunoita kuti ive sarudzo inosarudzika yekurongedza chikafu, sezvo ichiisa njodzi shoma yekusvibiswa.
Kutsigira Data uye Tsvakurudzo
Dhata kubva kuzvidzidzo zveindasitiri zvinotsigira kuchengetedzwa kwePE plastiki. Semuenzaniso, chidzidzo chakaitwa neEFSA chakawana kuti kutama kwezvinhu kubva kuP PE plastiki kuenda kuchikafu kwaive mukati memiganho yakachengeteka yakagadzwa. Pamusoro pezvo, iyo yakakwirira kudzokororwa kweP purasitiki inowedzera kuwedzera kukwezva kwayo, sezvo ichigona kunyatsogadziriswa kuita zvigadzirwa zvitsva, ichideredza kukanganiswa kwezvakatipoteredza.
Mukupedzisa,PE mabhegi, zipper bags,uyeziplock bagsyakagadzirwa kubva ku-chikafu-giredhi PE plastiki sarudzo dzakachengeteka uye dzakavimbika dzekurongedza chikafu. Kugadzikana kwavo kwemakemikari, kutevedzera mitemo yekuchengetedza, uye kushandiswa kwakapararira muindastiri kunoita kuti ive sarudzo yakanaka kune vatengi vari kutsvaga kuchengeta nekuchengetedza chikafu chavo. Kuti uwane rumwe ruzivo nezve PE plastiki uye mashandisiro ayo, ndapota tarisa kune zvakapihwa zviwanikwa.
