ʻOkoʻa ma waena o nā ʻeke BOPP, OPP a me PP.

Hoʻohana nui ka ʻoihana meaʻai i ka ʻōpala plastik BOPP. He maʻalahi ke paʻi, uhi a hoʻopaʻa ʻia nā ʻeke BOPP e kūpono ai no ka hoʻopili ʻana i nā huahana e like me nā huaʻai hou, nā mea ʻono a me nā meaʻai māmā. Me BOPP, hoʻohana pū ʻia nā ʻeke OPP, OPP, a me PP no ka hoʻopili ʻana. ʻO ka Polypropylene kahi polymer maʻamau i waena o nā mea ʻekolu i hoʻohana ʻia no ka hana ʻana i nā ʻeke.

ʻO OPP ke kū nei no Oriented Polypropylene, ʻo BOPP ke kū nei no Biaxially Oriented Polypropylene a ʻo PP ke kū nei no Polypropylene. ʻOkoʻa nā ʻekolu i ko lākou ʻano hana. ʻO Polypropylene i ʻike ʻia hoʻi he polypropene he polymer semi-crystalline thermoplastic. He paʻakikī, ikaika a he kūpaʻa kiʻekiʻe kona. Hana ʻia nā ʻeke kū, nā ʻeke spout a me nā ʻeke ziplock mai ka polypropylene.

He mea paʻakikī loa ka hoʻokaʻawale ʻana ma waena o nā plastik OPP, BOPP a me PP i ka wā mua. Hiki ke ʻike ʻia ka ʻokoʻa ma ka hoʻopā ʻana no ka mea he palupalu ka PP ʻoiai he palupalu ka OPP. He mea nui e hoʻomaopopo i ka hoʻohana ʻana o nā ʻeke OPP, PP a me BOPP i nā mea maoli no ka hoʻokaʻawale ʻana iā lākou. ʻO kaPPa i ʻole hoʻohana ʻia nā ʻeke polypropene e like me nā ʻeke i ulana ʻole ʻia. Hoʻomaʻamaʻa ʻia lākou i mea e omo ai i ka makū a i ʻole ka wai.

ʻO nā diapers, nā napkins hoʻomaʻemaʻe a me nā kānana ea i waena o nā mea ʻē aʻe he mau huahana PP maʻamau. Hoʻohana ʻia nā mea like no ka hana ʻana i nā lole wela no ka mea hāʻawi lākou i ka pale wela. He aniani ke kala o nā ʻeke OPP a he ikaika tensile kiʻekiʻe. Kūpaʻa lākou i nā mahana kiʻekiʻe akā ʻāwili inā lawe ʻia i ka hoʻohana ʻino. Hana ʻia nā lipine hoʻopili aniani me ka hoʻohana ʻana i ke ʻano like.

He paʻakikī ke haehae a hoʻohana ʻia nā ʻeke OPP i ka hoʻopili ʻana i ka ʻili a me nā lole i waena o nā mea ʻē aʻe. He mau ʻeke polyethylene moakaka nā ʻeke BOPP. Hāʻawi ke kuhikuhi biaxial iā lākou i kahi ʻano moakaka a kūpono iā lākou no ka hōʻailona ʻana ma ka paʻi ʻana ma luna o ka ʻili. Hoʻohana ʻia nā ʻeke BOPP no ka hoʻopili kūʻai liʻiliʻi. Hoʻonui ke kuhikuhi biaxial i ka ikaika a hiki iā lākou ke hāpai i nā ukana kaumaha.

He pale wai kēia mau ʻeke.

Pale ʻia nā huahana i loko o lākou mai ka makū no ka manawa lōʻihi. ʻO lākou ke koho mua ma ka ʻoihana hoʻopili lole. Kūpaʻa nā ʻeke PP, OPP a me BOPP i ka waikawa, alkalies a me nā mea hoʻoheheʻe organik. ʻO kēia ke kumu e hoʻohana ʻia ai lākou i ka ʻoihana hoʻopili kahi hiki ʻole ke pale ʻia ka mālama ʻana a me ka lawe ʻana ma lalo o ka lewa e loli nei. Hoʻopuka lākou i ka huahana mai ka makū a me ka lepo e like me nā kiʻiʻoniʻoni cling.

Hiki ke hana hou ʻia a ʻo kā lākou hana ʻana e pili ana i ka emi ʻana o ka hoʻopuka kalapona. Maikaʻi nō hoʻi nā ʻeke PP, BOPP a me OPP mai kahi manaʻo kaiapuni. He mea hana ʻeke BOPP ʻo Rishi FIBC a hāʻawi iā ia ma nā kumukūʻai mākeke kūpono.
