Kwihlabathi elikhulayo lokupakisha, ngakumbi kwiIshishini lengxowa elukiweyo le-pp.iinkampani ziya ziguqukela kwizixhobo ezidityanisiweyo zokhuseleko oluphuculweyo lwemveliso kunye nokuzinza. Iinketho ezithandwa kakhulu kwiingxowa ze-valve ezilukiweyo zintathu iintlobo ezahlukeneyo zokupakishwa kwe-composite: PP + PE, PP + PE + OPP kunye ne-PP + PE enephepha elilodwa le-kraft. Uhlobo ngalunye lusebenza ngenjongo ekhethekileyo kwaye luhlangabezana neemfuno zamashishini ahlukeneyo.

1. I-PP + PE (i-polypropylene kunye ne-polyethylene): Le ndibaniselwano isetyenziswa ngokubanzi ekusebenzeni kwayo okugqwesileyo kobumanzi kunye nokuqina. Uluhlu lwe-PP lunika amandla kunye nokuchasana nokukrazula, ngelixa i-PE layer inikezela ukuguquguquka kunye nomgangatho otywiniweyo. Olu hlobo lokupakishwa kweibhegi yevalve yebhlokhiilungele iimveliso zokutya, iqinisekisa ubutsha kunye nokwandisa ubomi beshelufu. Ikwasetyenziswa ngokuqhelekileyo ekupakishweni kwempahla yabathengi, apho ukhuseleko kwizinto zokusingqongileyo lubalulekile.

2. PP+PE+OPP (Oriented Polypropylene): Le composite ephucukileyo ithatha izibonelelo zodidi lokuqala inyathelo elongezelelweyo ngokongeza umaleko we-OPPiingxowa zevalve yebhlokhi, ephucula ukungafihli kunye nokuprintwa. Umaleko we-OPP unomphezulu omenyezelayo kwaye lukhetho olunomtsalane kwiibrendi ezijonge ukonyusa umtsalane wembonakalo yeemveliso zabo. Olu hlobo luthandwa kakhulu kwi-snack food and confectionery industry, apho imbonakalo idlala indima ebalulekileyo ekukhethweni kwabathengi.

3. PP+PE Iphepha le-Ply Kraft elinye: Olu khetho lwe-eco-friendly lweibhegi* yeenkwenkweziidibanisa amandla e-polypropylene kunye ne-polyethylene kunye nesibheno sendalo sephepha le-kraft. I-kraft paper layer ayigcini nje ukongeza i-rustic aesthetic, kodwa iphucula ukuphinda isetyenziswe. Olu hlobo lokupakisha luyanda kakhulu kwimveliso yezinto eziphilayo kunye nezendalo, apho ukuzinza kuyinkxalabo ephambili kubathengi.

Njengoko iinkampani ziqhubeka nokubeka phambili ukuzinza kunye nokuthembeka kwemveliso, ezi zisombululo zokupakishwa ezidibeneyo ziya kudlala indima ebalulekileyo kwikamva loshishino.
