ʻO ka Polypropylene a i ʻole PP kahi thermoplastic haʻahaʻa haʻahaʻa o ka mālamalama kiʻekiʻe, kiʻekiʻe gloss a me ka ikaika tensile maikaʻi.Loaʻa iā ia kahi helu hoʻoheheʻe kiʻekiʻe ma mua o ka PE, kahi e kūpono ai i nā noi e koi ana i ka sterilization ma nā wela kiʻekiʻe.He emi iki ka haze a ʻoi aku ka nani.ʻO ka maʻamau, ʻaʻole maikaʻi nā waiwai hoʻopaʻa wela o PP e like me ka LDPE.ʻOi aku ka ikaika o ka waimaka o LDPE a me ke kūpaʻa haʻahaʻa haʻahaʻa.
Hiki ke hoʻoheheʻe ʻia ʻo PP e hopena i ka hoʻomaikaʻi ʻana i nā waiwai pale kinoea no ke koi ʻana i nā noi kahi mea nui o ke ola o ka huahana.Ua kūpono nā kiʻiʻoniʻoni PP no kahi ākea o ka ʻenehana, nā mea kūʻai aku, a me nā noi kaʻa.
Hiki ke hoʻohana hou ʻia ʻo PP a hiki ke hana hou ʻia i nā huahana ʻē aʻe no nā noi like ʻole.Eia naʻe, ʻaʻole like me ka pepa a me nā huahana cellulose ʻē aʻe, ʻaʻole biodegradable ka PP.Ma ka ʻaoʻao, ʻaʻole hoʻopuka ka ʻōpala PP i nā mea ʻona a i ʻole nā huahana ʻino.
ʻO nā ʻano koʻikoʻi ʻelua ʻo ia ka polypropylene unoriented (CPP) a me ka polypropylene biaxially oriented (BOPP).Loaʻa nā ʻano ʻelua i ka ʻōlinolino kiʻekiʻe, optics ʻokoʻa, maikaʻi a maikaʻi paha ka hana hoʻopaʻa ʻana i ka wela, ʻoi aku ka maikaʻi o ka pale ʻana i ka wela ma mua o ka PE, a me nā waiwai pale pale.
Kiʻiʻoniʻoni Polypropylene (CPP)
Loaʻa i ka Cast unoriented Polypropylene (CPP) ka liʻiliʻi o nā noi ma mua o ka biaxially oriented polypropylene (BOPP).Eia nō naʻe, ke loaʻa mau nei ka CPP ma ke ʻano he koho maikaʻi loa i ka nui o ka hoʻopili maʻalahi kuʻuna a me nā noi hoʻopili ʻole.Hiki ke hoʻopilikino ʻia nā waiwai kiʻiʻoniʻoni e hoʻokō i nā koi kikoʻī kikoʻī, ka hana, a me ka hana ʻana.Ma keʻano laulā, ʻoi aku ka kiʻekiʻe o ka CPP i ka waimaka a me ke kūpaʻa hopena, ʻoi aku ka maikaʻi o ka hana wela anuanu a me nā waiwai hoʻopaʻa wela ma mua o BOPP.
Nā Kiʻiʻoniʻoni Polypropylene Kūleʻa Biaxially (BOPP)
ʻO ka polypropylene Biaxially a i ʻole BOPP1 ka kiʻiʻoniʻoni polypropylene koʻikoʻi.He koho maikaʻi loa ia i ka cellophane, ka pepa waxed, a me ka alumini alumini.Hoʻonui ka hoʻonohonoho ʻana i ka ikaika tensile a me ka ʻoʻoleʻa, hoʻohaʻahaʻa i ka elongation (ʻoi aku ka paʻakikī o ka hoʻolōʻihi ʻana), a hoʻomaikaʻi i nā waiwai optical, a hoʻomaikaʻi iki i nā waiwai pale mahu.Ma keʻano laulā, loaʻa ka BOPP i ka ikaika tensile kiʻekiʻe, ke kiʻekiʻe o ka modulus (koʻikoʻi), ka elongation haʻahaʻa, ka pale kinoea maikaʻi, a me ka haze haʻahaʻa ma mua o CPP.
Nā noi
Hoʻohana ʻia ka kiʻiʻoniʻoni PP no nā noi hoʻopili maʻamau e like me ka cigakeke, ka candy, ka meaʻai a me nā mea ʻai.Hiki ke hoʻohana ʻia no ka shrink wrap, tape liners, diapers a me sterile wrap i hoʻohana ʻia i nā noi olakino.Ma muli o ka loaʻa ʻana o ka PP i nā waiwai pale kinoea maʻamau, ua uhi pinepine ʻia me nā polymers ʻē aʻe e like me PVDC a i ʻole acrylic e hoʻomaikaʻi maikaʻi loa i kāna mau waiwai pale kinoea.
Ma muli o ka ʻala haʻahaʻa, ke kūpaʻa kemika kiʻekiʻe a me ka inertness, nui nā māka PP i kūpono no nā noi hoʻopili ma lalo o nā lula FDA.
