ʻO ka manaʻo hoʻololi o ka mālama ʻana i nā holoholona mai ke kūʻai ʻana i ka meaʻai holoholona a i ka kuke ʻana i ke kanaka ua hoʻokumu i kahi ala hou i ka ʻoihana meaʻai holoholona.Ke hoʻohālikelike ʻia me ka meaʻai maloʻo, ʻoi aku ka liʻiliʻi o nā kaʻina hana ʻai hou a ʻoi aku ka ʻōmaʻomaʻo a me ke kumu, e like me ka manaʻo ʻai o kēia manawa o nā mea mālama holoholona i ka ʻimi ʻana i ka hānai olakino.ʻOiai ʻaʻole lōʻihi loa ka mōʻaukala hoʻomohala ʻana ma Kina, ʻaʻole hiki ke hoʻohaʻahaʻa ʻia kona mākeke mākeke no ka mea ua kūlike ka meaʻai holoholona hou me ke ʻano ʻai.

Hōʻike ka pepa keʻokeʻo 2020 e pili ana i ka ʻoihana puaʻa Kina, i hoʻopilikia ʻia e ka COVID19, 34.1% o nā mea mālama holoholona e mālama i ka meaʻai i kēlā me kēia manawa, a ʻo 22.7% o nā mea mālama holoholona e kālele ana i ke ola o ka meaʻai holoholona.No laila, ʻelua mau kumu koʻikoʻi e pili ana i ka hoʻoholo kūʻai ʻana o ka mea kūʻai.ʻOi aku ka maikaʻi o ka ʻai ʻana o nā holoholona me ka ʻono, ka ʻono, ka paʻakikī o ka lawe ʻana a me ka waiwai waiwai.ʻO ka hou o ka meaʻai i hoʻopaʻa ʻia e pili nui ana i ka oxygen transmittance ratio (OTR) o ka paʻi.ʻO ke kiʻi ʻoniʻoni a Xiamen Changsu, nā huahana Supamidseries – EHA film, ʻo 15 μm wale nō ka mānoanoa.a ʻo kāna OTR e hoʻomalu ʻia ma lalo o 2cc / (㎡. Day. atm), ʻaʻole hiki ke hoʻopaʻa paʻa i ka hou o ka meaʻai a hoʻemi nui i ka nalowale o nā meaʻai, akā hoʻolōʻihi i ke ola o ka mālama ʻana a hoʻokō i ka manaʻo o nā mea mālama holoholona. hoʻahu ʻai holoholona.

ʻAʻole wale ia, hōʻike pū ka pepa keʻokeʻo 2020 i ka helu o nā mea mālama holoholona i ka post-80s a me ka post-90s helu no 74.3%.Ma waena o lākou, 84.5% o ka post-90s a me 83.5% o ka post-80s ʻoi aku ka makemake e koho i ke kūʻai pūnaewele e like me kā lākou kūʻai ʻana i nā meaʻai holoholona, ​​​​e hoʻopiʻi hou aku i ka ikaika o ka ʻeke meaʻai.ʻO ke kiʻekiʻe o ka ʻaʻahu o waho a i ʻole ka haki ʻana o ka ʻeke o nā mea kūʻai pūnaewele ma ke kaʻina o ka lawe ʻana he kumu nui ia e pili ana i nā manawa kūʻai hou.Me ka maikaʻi o ka maʻalahi, ka hopena a me ka flex-crack resistance, a me ka maikaʻi o ka tensile a me ka puncture resistance, hiki i ke kiʻi ʻoniʻoni EHA ke pale i nā mea i ka wā o ka lawe ʻana a hoʻomaikaʻi piha i ka ʻike kūʻai pūnaewele o nā mea kūʻai.

Ma muli o nā koi o nā kahu hānai no ka meaʻai pipi,EHAʻO ke kiʻiʻoniʻoni, me kāna mau pono huahana ikaika, ua hui pū me nā meaʻai meaʻai holoholona he nui e hana pū i ka hāʻawi ʻana i ka meaʻai holoholona hou, olakino a me ka meaʻai.
