ʻO Stretch film kahi kiʻiʻoniʻoni plastik i hoʻohana nui ʻia i ka hoʻopili logistic, ka hana ʻenehana a me ka pale o nā mea kūʻai aku. Hoʻopili pololei ke koho mea i ka hana, ke kumukūʻai a me ke aloha o ka huahana. ʻO ka hoʻomaopopo ʻana i nā mea nui a me nā hiʻohiʻona o ka stretch film e kōkua i nā mea kūʻai aku a me nā mea hoʻohana hope e hana i nā koho kūpono e pili ana i nā pono maoli.
Polyethylene (PE) - ka mea nui o ke kiʻi ʻoniʻoni
ʻO Polyethylene (PE no ka pōkole) ka mea maʻamau maʻamau kiʻi ʻoniʻoni ma ka mākeke. Hiki ke hoʻokaʻawale ʻia i ka polyethylene haʻahaʻa haʻahaʻa (LDPE), polyethylene haʻahaʻa laina haʻahaʻa (LLDPE) a me ka polyethylene kiʻekiʻe (HDPE) e like me nā density like ʻole. I waena o lākou, ua lilo ʻo LLDPE i koho nui o ke kiʻi ʻoniʻoni ma muli o kona ikaika tensile maikaʻi loa, ke kūpaʻa puncture a me ka maʻalahi.
ʻO ke kiʻi ʻoniʻoni ʻoniʻoni ʻo LDPE ke ʻike maikaʻi ʻia, akā nāwaliwali nā waiwai tensile, a hoʻohana nui ʻia no ka hoʻopili ʻana i nā mea māmā. Hoʻohana nui ʻia ke kiʻi ʻoniʻoni LLDPE i nā ukana kaumaha, pallet packaging a me nā māla ʻē aʻe ma muli o kona ikaika tensile kiʻekiʻe a me ke kūpaʻa. ʻOiai ʻoi aku ka ikaika o ke kiʻi ʻoniʻoni HDPE, ʻaʻole hiki ke maʻalahi a hoʻohana maʻamau ʻia i nā hiʻohiʻona paʻi me nā pono kūikawā.
Polypropylene (PP) - Koho ʻO ka ikaika kiʻekiʻe a me ka wela
Loaʻa i ka Polypropylene (PP) stretch film i kekahi mau wahi kikoʻī ma muli o kona ikaika tensile kiʻekiʻe a me ke kūpaʻa wela. ʻOi aku ka paʻakikī o ka kiʻi ʻoniʻoni ʻo PP ma mua o ka PE kiʻi ʻoniʻoni a kūpono ia no nā wahi hoʻopili e pono ai ke kū i nā wela kiʻekiʻe a i ʻole ke kaumaha mechanical, e like me nā huahana kemika, nā mea kūkulu hale, a me nā mea ʻē aʻe.
ʻO nā mea hiki ke hoʻopau ʻia - he koho hou ma lalo o ke au o ka mālama kaiapuni
Me ka piʻi ʻana o ka ʻike kaiapuni, ua lilo mālie ke kiʻi ʻoniʻoni degradable i mea wela i ka ʻoihana. Hana ʻia kēia ʻano mea me nā mea i hoʻopaʻa ʻia i ka bio{1}}pilikia (e like me PLA, PHA) a i ʻole PE/PP me nā mea hoʻohaʻahaʻa i hoʻohui ʻia, hiki ke hoʻoheheʻe wikiwiki ʻia i ke kaiapuni kūlohelohe a hōʻemi i ka pollution plastic. ʻOiai ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ke kiʻi ʻoniʻoni degradable i kēia manawa, me ka holomua ʻenehana a me ka hoʻolaha ʻana i nā kulekele, manaʻo ʻia e hoʻonui lohi ka mākeke.
Hōʻuluʻulu manaʻo
Pono ke koho waiwai o ke kiʻi ʻoniʻoni e noʻonoʻo piha i nā pono o ka pahu, ke kumu kūʻai a me nā kumu kaiapuni. ʻO ka mea PE ka mea nui o ka mākeke ma muli o kāna hana piha piha, ʻoiai ʻo PP a me nā mea degradable e hāʻawi i nā mea hou aʻe no nā hiʻohiʻona kikoʻī. I ka wā e hiki mai ana, me ka holomua o ka ʻepekema waiwai, e ʻoi aku ka nui o nā mea o ka kiʻi ʻoniʻoni e hoʻokō i nā pono o nā ʻoihana like ʻole.
