Kuyambira m'zaka za m'ma 21, moyo wa anthu ukupitirizabe kuyenda bwino, komanso umakhala wofunika kwambiri ku zovuta zachilengedwe, ndiyeno thumba la pulasitiki la chitetezo cha chilengedwe linabadwa, ndipo mwamsanga likhale lokondedwa kwambiri la anthu.Nawa mawu oyambira osavuta aukadaulo wamakampani opanga ma thumba apulasitiki.

Mu 2002, gulu la zinthu zatsopano ndi matekinoloje atsopano anatulukira, kuphatikizapo kukana mkulu permeability, Mipikisano zinchito pulasitiki filimu, aseptic ma CD chitukuko filimu mofulumira, choyambirira gulu filimu akupita ku mlingo wakuya, thumba kupanga, luso kusindikiza pa mlingo watsopano. , m’nyengo ya “kusintha kwamitundu”.

Kukula kwaukadaulo wa multilayer co-extrusion kwasintha kapangidwe ka filimu yogwira ntchito ndi chidebe, ndikusinthidwa kuti zigwirizane ndi msika.Pakukula kwachuma chamsika, kulongedza zinthu zofunika tsiku ndi tsiku, zodzikongoletsera, kunyamula chakudya, kunyamula zida zapakhomo zapereka zofunika kwambiri.

Masamba ndi zipatso zatsopano zopangira mafilimu amsika amayembekeza mokulira, pakadali pano, filimu ya polyethylene ndi filimu ya polypropylene ndiye zida zomwe zimagwiritsidwa ntchito kwambiri ndi zipatso ndi ndiwo zamasamba.Zipatso ndi ndiwo zamasamba zosiyanasiyana zimakhala ndi zofunika zosiyanasiyana pamatumba atsopano.Ndi matumba amtundu wanji wa filimu omwe ayenera kusankhidwa pazinthu zotsatirazi: mpweya woyenera wa mpweya ndi ndende yoyenera ya O2 ndi CO2.Onjezani mpweya wa ethylene.Mwa kuyamwa ethylene yotulutsidwa ndi chipatsocho, imachedwetsa kupuma kwa chipatsocho ndikupangitsa kuti ikhale yatsopano.

Ziribe kanthu kuti ndi makampani ati a matumba oyikapo pulasitiki kuti apulumuke komanso kusinthika kosalekeza.Tikukonza nthawi zonse ndikukonza zinthu zathu kuti tipeze msika waukulu pampikisano.
