•Makemake mākou e kapa i nā ʻeke hoʻopili palupalu plastik.

•ʻO ka ʻōlelo maoli, ʻo ia hoʻi, ua hoʻopaʻa ʻia a hui pū ʻia nā mea kiʻiʻoniʻoni o nā waiwai like ʻole e hoʻokani i ke kuleana o ka lawe ʻana, pale ʻana a me ka hoʻonaninani ʻana i nā huahana.

•ʻO ka ʻeke ʻōpala composite ke ʻano o kahi papa o nā mea like ʻole i hui pū ʻia.

•ʻO ka papa nui o nā ʻeke ʻōpala e hoʻokaʻawale ʻia e ka papa waho, ka papa waena, ka papa o loko, a me ka papa hoʻopili. Hoʻohui ʻia lākou i nā lālani like ʻole e like me nā ʻano like ʻole.

•E wehewehe ʻo YPAK i kēia mau papa iā ʻoe:

•1. ʻO ka papa waho loa, i kapa ʻia hoʻi ʻo ka papa paʻi a me ka papa kumu, pono nā mea me ka hana paʻi maikaʻi a me nā waiwai optical maikaʻi, a ʻoiaʻiʻo hoʻi ke kūpaʻa wela maikaʻi a me ka ikaika mechanical, e like me BOPP (polypropylene i hoʻolōʻihi ʻia), BOPET, BOPA, MT, KOP, KPET, polyester (PET), nylon (NY), pepa a me nā mea ʻē aʻe.

•2. Ua kapa ʻia hoʻi ka papa waena ʻo ka papa pale. Hoʻohana pinepine ʻia kēia papa e hoʻoikaika i kahi hiʻohiʻona o ka ʻano hui. Pono ia e loaʻa nā waiwai pale maikaʻi a me ka hana poly moisture-proof maikaʻi. I kēia manawa, ʻo nā mea maʻamau ma ka mākeke ʻo ia ka alumini foil (AL) a me ka alumini-plated film (VMCPP). , VMPET), polyester (PET), nylon (NY), polyvinylidene chloride coated film (KBOPP, KPET, KONY), EV, etc.

•3. ʻO ke kolu o ka papa ka mea o loko, i kapa ʻia hoʻi ʻo ka papa sila wela. ʻO ke ʻano o loko e pili pono ana i ka huahana, no laila pono ka mea i ka hiki ke hoʻololi, ke kū'ē i ka permeability, ka sila wela maikaʻi, ka transparency, ka wehe ʻana a me nā hana ʻē aʻe.

•Inā he meaʻai i hoʻopili ʻia, pono nō hoʻi he mea ʻawahia ʻole, ʻono ʻole, kūpaʻa i ka wai, a kūpaʻa i ka ʻaila. ʻO nā mea i hoʻohana pinepine ʻia ʻo LDPE, LLDPE, MLLDPE, CPP, VMCPP, EVA (ethylene-vinyl acetate copolymer), EAA, E-MAA, EMA, EBA, Polyethylene (PE) a me kāna mau mea i hoʻololi ʻia, a pēlā aku.
