Qalabka baakadaha isku dhafan

Iyada oo ku saleysan horumarinta warshadaha baakadaha, baakadaha alaabada ayaa leh

sidoo kale waa loo horumariyay. Laga soo bilaabo baakadaha fudud ee waraaqaha, ilaa hal lakab oo baakad filim caag ah, oo loo sameeyay isticmaalka ballaaran ee alaabta isku dhafan. Filim isku-dhafan ayaa ka dhigi kara waxyaabaha ku jira baakadu inay yeeshaan sifooyinka qoyaanka, udgoonka, quruxda, ilaalinta, iftiinka, ka fogaanshaha, dhexgalka, dheereynta nolosha shelf iyo sifooyinka kale, si aan u helno horumar degdeg ah.

Maaddooyinka isku dhafan waa laba ama in ka badan oo walxo, iyada oo loo marayo hal ama in ka badan oo habab isku dhafan oo la isku daray, si ay u noqdaan hawl gaar ah oo ka mid ah walxaha isku dhafan. Guud ahaan waxa loo qaybin karaa lakabka salka, lakabka shaqaynaysa iyo lakabka kulaylka. Heerka salka ayaa inta badan ka ciyaara qurux, daabacaad, caabbinta qoyaanka iyo door kale. Sida BOPP, BOPET, BOPA, MT, KOP, KPET, iwm., lakabka shaqeynaya inta badan wuxuu xannibaa oo ka ilaaliyaa hawlaha iftiinka, sida VMPET, AL, EVOH, PVDC; lakabka daboolida kulaylka ayaa xiriir toos ah la leh alaabta baakadaha, la qabsiga, caabbinta permeability, xirida kulaylka wanaagsan, sida LDPE, LLDPE, MLLDPE, CPP, VMCPP, EVA, EAA, E-MAA, EMA, EBA, iwm
