He aha ka ʻoniʻoni Polypropylene Overwrap Biaxially Oriented?
ʻO ka ʻili polypropylene i kuhikuhi ʻia ma ke ʻano Biaxially (BOPP) kahi ʻano ʻili hoʻopili palupalu. Hoʻolōʻihi ʻia ka ʻili polypropylene overwrap i kuhikuhi ʻia ma nā ʻaoʻao mīkini a me nā ʻaoʻao transverse. ʻO kēia ka hopena i kahi kuhikuhi kaulahao molekala ma nā ʻaoʻao ʻelua. Hana ʻia kēia ʻano ʻili hoʻopili palupalu ma o kahi kaʻina hana tubular.
