Isikhwama sephepha esilukiwe nge-poly siwuhlobo olukhethekile lwesikhwama esilukiwe nge-poly.Lesi sikhwama siyisikhwama sephepha kanye ne-poly composite esakhiwe ngephepha le-Kraft esinamekwe phezu kwendwangu ephothiweyo.Ezimweni zokuphatha eziqinile, isikhwama sephepha se-polyluven sizogqama ngaphezu kwesikhwama sakho sephepha esivamile ngenxa yamandla aso aphezulu, ukuqina kanye nokumelana nokukhala.Lesi sikhwama sizoqukatha ngokuphephile nangokuvikelekile umkhiqizo wakho ozowuhambisa futhi sigweme izindleko ezingaba khona zokulahlekelwa komkhiqizo okuvela ngokuphuka.Njengoba siyisikhwama esiminyene esinendawo eqinile futhi eyisicaba efana nesikhwama sephepha esinama-multiwall, isikhwama sephepha esilukiwe nge-poly singasetshenziswa kumishini yokupakisha yesikhwama sephepha eningi ukuze ugcwalise noma unciphise imigqa yakho yezikhwama ngokuzenzakalelayo.
