Incazelo emfushane:

Ifilimu evala uphawu ebandayo, eyaziwa nangokuthi i-cold seal packaging noma isitokwe se-cold seal, iwuhlobo lwempahla yokupakisha eguquguqukayo engadingi ukushisa noma okunamathelayo ukuze ivalwe. Kuvame ukusetshenziswa embonini yokudla ukupakisha imikhiqizo efana noswidi, amabha kashokoledi, ama-granola bar, namakhukhi.

Ifilimu ebandayo yokuvala uphawu ngokuvamile yenziwe ngesakhiwo se-multilayer, okuhlanganisa izingqimba ze-polyethylene, iphepha, ne-adhesive ekhethekile yophawu olubandayo. Ifilimu iklanyelwe ukuthi ibe ne-coefficient ephansi yokungqubuzana, okuvumela ukuthi ivalwe kalula ngaphandle kwesidingo sokushisa. Uma kufakwa ingcindezi, i-cold seal adhesive bonds ne-package surface, okwenza uphawu oluqinile futhi oluvikelekile.

Kunezinzuzo eziningana zokusebenzisa ifilimu yokuvala uphawu ebandayo. Enye yezinzuzo eziyinhloko ukuthi iqeda isidingo semishini yokuvala ukushisa, ukunciphisa ukusetshenziswa kwamandla kanye nezindleko zokukhiqiza. Iphinde ivumele isivinini sokupakisha esisheshayo futhi ithuthukise ukusebenza kahle kokusebenza. Ukwengeza, ifilimu ebandayo yokuvala uphawu inikeza uphawu olubonakalayo, okuqinisekisa ubuqotho bomkhiqizo ohlanganisiwe.

Sekukonke, ifilimu yokufaka uphawu ebandayo inikeza isixazululo esikahle nesingabizi kakhulu sokupakisha imikhiqizo ehlukahlukene yokudla, ihlinzeka ngophawu oluvikelekile ngaphandle kwesidingo sokushisa noma ukunamathela.
