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

Hoʻohana nui ka ʻoihana meaʻai i ka pahu plastik BOPP. He maʻalahi ka paʻi ʻana o nā ʻeke BOPP, ka lole a me ka laminate e kūpono ai no ka hoʻopili ʻana i nā huahana e like me nā huahana hou, nā mea ʻono a me nā meaʻai. Hoʻohana pū ʻia nā ʻeke BOPP, OPP, a me PP no ka hoʻopili ʻana. ʻO ka polypropylene kahi polymer maʻamau i waena o nā ʻekolu i hoʻohana ʻia no ka hana ʻana i nā ʻeke.

Kū ʻo OPP no Oriented Polypropylene, kū ʻo BOPP no Biaxially Oriented Polypropylene a ʻo PP no Polypropylene. ʻOkoʻa nā mea ʻekolu i kā lākou ʻano hana. ʻO ka polypropylene i kapa ʻia ʻo polypropene he thermoplastic semi-crystalline polymer. He ʻoʻoleʻa, ikaika a loaʻa ka hopena kiʻekiʻe. 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 OPP, BOPP a me PP plastics i ka wā mua. Hiki ke ʻike ʻia ka ʻokoʻa ma ka hoʻopā ʻana no ka palupalu ʻana o PP aʻo ka OPP he palupalu. He mea nui e hoʻomaopopo i ka hoʻohana ʻana i nā ʻeke OPP, PP a me BOPP i nā mea honua maoli no ka hoʻokaʻawale ʻana iā lākou. ʻO kaPPa i ʻole ʻeke polypropene e hoʻohana ʻia e like me nā ʻeke i ulana ʻole ʻia. Hoʻomaʻamaʻa ʻia lākou i mea e hoʻomaʻemaʻe ai i ka wai.

ʻO nā diapers, nā kāwele hoʻomaʻemaʻe a me nā kānana ea ma waena o nā huahana PP maʻamau. Hoʻohana ʻia nā mea like no ka hana ʻana i nā lole wela me ka hāʻawi ʻana i ka pale wela. ʻIke ʻia nā ʻeke OPP i ke kala a loaʻa ka ikaika tensile kiʻekiʻe. Kūleʻa lākou i nā wela kiʻekiʻe akā wrinkle inā hoʻohana ʻia. Hana ʻia nā lipine adhesive māmā me ka hoʻohana ʻana i ke ʻano like.

Paʻakikī lākou e 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. ʻO nā ʻeke BOPP nā ʻeke polyethylene akaka. Hāʻawi ka biaxial orientation iā lākou i nā hiʻohiʻona akaka a kūpono iā lākou no ka hoʻopaʻa inoa ʻana ma ka paʻi ʻana ma ka ʻili. Hoʻohana ʻia nā ʻeke BOPP no ka ʻeke kūʻai. Hoʻonui ka orientation biaxial i ka ikaika a hiki iā lākou ke lawe i nā ukana kaumaha.

He wai wai kēia mau ʻeke.

Mālama ʻia nā huahana i loko o lākou mai ka makū no ka manawa lōʻihi. ʻO lākou ka koho mua i ka ʻoihana pale lole. Kūleʻa nā ʻeke PP, OPP a me BOPP i ka waika, alkalies a me nā mea hoʻoheheʻe organik. ʻO ia ke kumu i hoʻohana ʻia ai lākou i ka ʻoihana paʻa kahi e hiki ʻole ai ke pale aku i ka mālama ʻana a me ka lawe ʻana ma lalo o ka loli ʻana o ka lewa. Hoʻolālā lākou i ka huahana mai ka makū a me ka lepo e like me nā kiʻi ʻoniʻoni.

Hiki ke hana hou ʻia a hoʻemi ʻia kā lākou hana ʻana i ke kalapona. He maikaʻi nō hoʻi nā ʻeke PP, BOPP a me OPP mai kahi ʻike kaiapuni. ʻO Rishi FIBC kahi mea hana ʻeke BOPP a hāʻawi iā ia i nā kumukūʻai mākeke kūpono.
