①Pepa-plastik mea hui. He maikaʻi ka paʻi ʻana o ka pepa, ka ea permeability maikaʻi, ke kūpaʻa wai maikaʻi ʻole, a me ka deformation i ka pilina me ka wai; ʻOi aku ka maikaʻi o ka pale wai a me ka paʻa o ka ea, akā maikaʻi ʻole ka paʻi ʻana. Ma hope o ka hoʻohui ʻia ʻana o nā mea ʻelua, ua hoʻokumu ʻia nā mea i hoʻohui ʻia e like me ka plastic-pepa (plastic film as the surface material), pepa-plastic (pepa e like me ka mea ʻili), a me ka plastic-pepa-plastic. Hiki i ka pepa-plastic composite material ke hoʻomaikaʻi i ke kūpaʻa ʻana o ka moisture o ka pepa, a i ka manawa like me kahi sealability wela. Hiki ke hoʻohui ʻia e ke kaʻina hana hoʻohui maloʻo, ke kaʻina hoʻohui wai a me ke kaʻina hoʻohui extrusion.

②Plastic composite mea. ʻO nā mea palaki-plastic composite ka mea maʻamau o nā mea hana. Loaʻa i nā kiʻiʻoniʻoni plastik ko lākou pono ponoʻī a me nā hemahema. Ma hope o ka hoʻohui ʻana iā lākou, loaʻa i nā mea hou nā waiwai maikaʻi loa e like me ke kūpaʻa ʻana i ka ʻaila, ka pale ʻana i ka wai, a me ka sealability wela. Ma hope o ka hoʻohui ʻana i ka plastic-plastic, hiki ke hana ʻia nā ʻāpana ʻelua, ʻekolu-layer, ʻehā-papa a me nā mea hoʻohui ʻē aʻe, e like me: OPP-PE BOPET - PP, PE, PT PE-evoh-PE.

③Aluminum-plastic composite mea. ʻOi aku ka maikaʻi o ka paʻa ʻana o ka ea a me nā mea pale o ka pahu alumini ma mua o ke kiʻi ʻoniʻoni, no laila i kekahi manawa hoʻohana ʻia ka plastic-aluminum-plastic composite, e like me PET-Al-PE.

④Pepa-alumini-plastic composite mea. Hoʻohana ka pepa-aluminum-plastic composite material i ka paʻi maikaʻi o ka pepa, ka maikaʻi o ka moisture-proof a me ka thermal conductivity o ka alumini, a me ka hoʻopaʻa wela maikaʻi o kekahi mau kiʻiʻoniʻoni. Hiki i ka hui ʻana iā lākou ke loaʻa i kahi mea hoʻohui hou. E like me ka pepa-aluminika-polyethylene.

Mīkini Fexoʻaʻohe mea o ke ʻano o ka mea i hoʻohui ʻia, pono ia e paʻi maikaʻi ka ʻaoʻao o waho a me nā waiwai mechanical, ʻo ka ʻaoʻao o loko ka adhesion hoʻopaʻa wela, a ʻo ka papa waena nā waiwai e pono ai nā mea i loko, e like me ka pale ʻana i ka māmā, ka pale ʻana a pēlā aku.
