LGLPAK yakhala ikuyang'ana kwambiri pazinthu zapulasitiki, ndipo kukulunga pulasitiki ndi chinthu wamba.
Filimu ya Cling ndi mtundu wazinthu zopangira pulasitiki, zomwe nthawi zambiri zimapangidwa ndi polymerization reaction ndi ethylene ngati batch master.
Filimu yodyera ikhoza kugawidwa m'magulu atatu:
yoyamba ndi polyethylene, yotchedwa PE;
yachiwiri ndi polyvinyl chloride, yotchedwa PVC;
Chachitatu ndi polyvinylidene chloride, kapena PVDC mwachidule.
Kutenthetsa chakudya cha microwave, kusunga chakudya mufiriji, kulongedza zakudya zatsopano ndi zophika ndi zochitika zina, pankhani ya moyo wabanja, masitolo akuluakulu, mahotela ndi malo odyera, ndi kulongedza chakudya cha mafakitale, ambiri a pulasitiki ndi matumba apulasitiki omwe amagwiritsidwa ntchito nthawi zambiri amagulitsidwa pamsika. amapangidwa ndi Ethylene masterbatch ndi zopangira.
Malingana ndi mitundu yosiyanasiyana ya ethylene masterbatch, filimu yodyera ikhoza kugawidwa m'magulu atatu.
Yoyamba ndi polyethylene, kapena PE mwachidule.Izi makamaka ntchito ma CD chakudya.Kanema yemwe timakonda kugula zipatso ndi ndiwo zamasamba, kuphatikiza zinthu zomwe zatha kugulidwa kusitolo, zonse zimagwiritsidwa ntchito pazinthu izi;
Mtundu wachiwiri ndi polyvinyl chloride, kapena PVC mwachidule.Izi zitha kugwiritsidwanso ntchito pakuyika chakudya, koma zimakhudza kwambiri chitetezo chathupi la munthu;
Mtundu wachitatu ndi polyvinylidene chloride, kapena PVDC mwachidule, amene makamaka ntchito ma CD yophika chakudya chophika, nyama ndi zinthu zina.
Pakati pa mitundu itatu ya kukulunga pulasitiki, PE ndi PVDC pulasitiki pulasitiki ndi yotetezeka kwa thupi la munthu ndipo ingagwiritsidwe ntchito molimba mtima, pamene PVC yokulunga ili ndi carcinogens ndipo imakhala yovulaza thupi la munthu.Chifukwa chake, pogula zokutira zapulasitiki, Zopanda poizoni ziyenera kugwiritsidwa ntchito.
Kuchokera pamalingaliro a thupi, filimu yotsatirira imakhala ndi mpweya wokwanira wa okosijeni ndi kutsekemera kwa chinyezi, imasintha mpweya ndi chinyezi kuzungulira chinthu chosungira mwatsopano, imatchinga fumbi, ndikutalikitsa nthawi yosungira mwatsopano chakudya.Choncho, m'pofunika kusankha mapepala apulasitiki osiyanasiyana pazakudya zosiyanasiyana.
Pambuyo pomvetsetsa, aliyense ayenera kumvetsera kusankha posankha filimu yodyera m'moyo watsiku ndi tsiku kuti apewe zinthu zoopsa.
