Ifilimu Yokwelula Umshini, eyaziwa nangokuthi i-Stretch Wrap noma i-Pallet stretch wrap, iwuhlobo lwezinto zokupakisha ezivame ukusetshenziswa kuzilungiselelo zezimboni zokuvikela nokuvikela izimpahla ezinamaphalethi ngesikhathi sokugcinwa nokuhamba.Ibizwa ngokuthi "umshini" Ifilimu Yokunwebeka ngoba isetshenziswa kakhulu nemishini yokugoqa ezenzakalelayo eyenza inqubo yokugoqa.

Ifilimu enwetshiwe yomshini yenziwe nge-linear low-density polyethylene (LLDPE) resin, ehlala isikhathi eside futhi enwebekayo.Ikhiqizwa kusetshenziswa inqubo ebizwa ngokuthi i-cast extrusion, lapho inhlaka encibilikisiwe ikhishwa ngefa eliyisicaba kurola obandayo, kwakheka ifilimu elincanyana, eliqhubekayo.

Isici esiyinhloko sefilimu yokwelula umshini yikhono layo lokunwebeka kakhulu ngaphandle kokudabula.Lokhu kunwebeka kuvumela ifilimu ukuthi ivumelane ngokuqinile eduze kwamaphalethi nokuqukethwe kwawo, kudala umthwalo ovikelekile futhi ozinzile.Ifilimu ivamise ukusetshenziswa ngezendlalelo eziningi ukuze kuthuthukiswe amandla ayo nokuzinza komthwalo.

Ifilimu elula yomshini inikeza izinzuzo eziningana:
I-1.Ukuzinza Komthwalo: Ihlinzeka ngokuqukatha okuhle kakhulu komthwalo, ukuvimbela imikhiqizo ku-pallet kusukela ekushintsheni, ukuwa, noma ukulimala ngesikhathi sokuphatha nokuhamba.

2.Ukuvikela: Kusebenza njengesivikelo esikhumbeni somswakama, uthuli, ukungcola, nokunye ukungcola, ukugcina impahla ihlanzekile futhi iphelele.

3.I-Tamper-Evidence: Ifilimu enwetshiwe yomshini ingasebenza njengesivimbeli esibonakalayo ngokumelene nokuphazamisa, njengoba noma yikuphi ukufinyelela okungagunyaziwe noma ukuphazamisa kungabonakala ngokushesha.

I-4.I-Cost-Effective: Kuyisisombululo sokupakisha esingabizi kakhulu uma kuqhathaniswa nezinye izinto ezifana ne-Stpping noma i-shrink wrapping.

I-5.Ukusebenza kahle: Ukusetshenziswa kwemishini yokugoqa yokwelula kwenza imisebenzi yokupakisha esheshayo futhi ephumelelayo, ukunciphisa izidingo zabasebenzi kanye nokwenza ngcono ukukhiqiza.

I-6.Ifilimu yokwelula yomshini itholakala ngobubanzi obuhlukahlukene, ubukhulu, namandla ukuze kuhambisane nobukhulu obuhlukahlukene bomthwalo nezisindo.Ingase futhi ize ngezindlela ezihlukahlukene, njengefilimu enwetshiwe ngaphambili noma amafilimu asebenza kahle kakhulu anezici ezengeziwe ezifana nokumelana nokubhoboza noma ukuvikelwa kwe-UV, kuye ngezidingo ezithile zohlelo lokusebenza.

Sekukonke, i-Pallet Stretch Film idlala indima ebalulekile ekuqinisekiseni ukuthunyelwa okuphephile nokuvikelekile kwe-palletized, ihlinzeka ngokuzinza, ukuvikelwa, nokusebenza kahle embonini yezokuthutha kanye ne-supply chain.
