I mea e hoʻonui ai i ke ola o ka meaʻai, ka lāʻau lapaʻau a me nā mea ʻē aʻe, ua hoʻohana ka nui o nā meaʻai a me nā mea hoʻopili lāʻau i kēia manawa i nā kiʻiʻoniʻoni multi-layer co-extrusion composite.I kēia manawa, ʻelua, ʻekolu, ʻelima, ʻehiku, ʻeiwa, a hiki i ʻumikumamākahi papa o nā mea hoʻopili hoʻopili.ʻO ke kiʻiʻoniʻoni co-extrusion multi-layer he kiʻiʻoniʻoni e hoʻokuʻu i nā ʻano mea palaki like ʻole mai ka make hoʻokahi i ka manawa like ma o nā kahawai he nui, hiki ke hāʻawi i ka pāʻani i nā pono o nā mea like ʻole.
ʻO ka nui-layer co-extruded composite film i haku nui ʻia me ka polyolefin.I kēia manawa,ʻo nā hale i hoʻohana nuiʻia e like me: polyethylene / polyethylene, polyethylene / vinyl acetate copolymer / polypropylene, LDPE / adhesive layer / EVOH / adhesive layer / LDPE, LDPE / adhesive layer / EVOH / EVOH / adhesive layer / LDPE.Hiki ke hoʻololi i ka mānoanoa o kēlā me kēia papa e ke kaʻina extrusion.Ma ka hoʻoponopono ʻana i ka mānoanoa o ka ʻāpana pale a me ka hoʻohana ʻana i nā ʻano mea pale like ʻole, hiki ke hoʻolālā ʻia ke kiʻiʻoniʻoni me nā ʻano pale like ʻole, a hiki ke hoʻololi ʻia ka mea hoʻopaʻa wela a hoʻokaʻawale ʻia no ka hoʻokō ʻana i nā pono o nā ʻāpana like ʻole.ʻO kēia multilayer a me ka multi-function co-extrusion compound ke kuhikuhi nui o ka hoʻomohala ʻana i nā mea kiʻi ʻoniʻoni i ka wā e hiki mai ana.
