1. Ukusetha okungenangqondo kokushisa okushisa kuholela ekugqineni okungalingani kwe-Stretch Film, ngoba izinga lokushisa lithinta ngokuqondile ukuncibilika esiteshini sokugeleza kwekhanda lesikhunta.

Iphethini yokugeleza, nokuhlobene nokusatshalaliswa kogqinsi kwe-longitudinal komkhiqizo, kufanele kuhlole ukuthi idivayisi yokushisisa nedivayisi yokulawula izinga lokushisa yonakele, ukushisisa ngakunye.
Ukushisa kwendawo kunengqondo ukuqinisekisa ukuzinza kwezinga lokushisa lokushisa.

2. Ezinye igebe lokufa alifani, ezinye izingxenye zegebe zikhulu, ezinye izingxenye zegebe zincane, okuholela emalini ye-extrusion.
Ngakho-ke, ukushuba kwefilimu eqinile eyakhiwe akuhambisani, ezinye izingxenye zincane, ezinye izingxenye ziwugqinsi, bese thina kuphela.
Ukulungisa imvume yomlomo wokufa kwekhanda, ukuqinisekisa umfaniswano yonke indawo;

3. Ivolumu yokuphakelwa komoya ezungeze indandatho yomoya opholile ayihambisani, okuholela kumphumela wokupholisa ongalingani, ukuze ugqinsi lwefilimu elula lubonakale lungalingani.

Isenzo esifanayo, khona-ke sidinga ukulungisa idivayisi yokupholisa, ukuqinisekisa ukuthi umthamo womoya we-outlet ufana;Uma isivinini sokudonsa singashintshi futhi cha
Ukushintsha kwekhefu kuzoholela futhi ekugqineni okungalingani kwefilimu enwetshiwe ekhiqiziwe, bese uhlola idivayisi yokudlulisa ngomshini ukwenza ukudonsa.
Isivinini sihlala singashintshi.
