EHAp - BOPA Film me ke Kiʻi Paʻi Kiʻekiʻe
Hoʻolālā kūikawā ʻia a hana ʻia ʻo EHAp ma ke kaʻina hana hoʻolōʻihi like ʻana o LISIM.Loaʻa i nā huahana paʻa hou ka waiwai pale kiʻekiʻe loa, ʻo kāna noi composite me nā mea hoʻopihapiha meaʻai hiki ke hōʻemi i ka hoʻohana ʻana i nā mea hoʻohui, hoʻonui i ke ola o ka meaʻai, laka i ka hou a mālama i ka ʻala, a he mau mea nui ia e hāpai i ka hoʻomaikaʻi maikaʻi ʻana o nā meaʻai a hōʻemi. ʻānai ʻai.
Ke hoʻohālikelike ʻia me ka EVOH co-extrusion kiʻiʻoniʻoni, hiki i ka EHA ke hoʻokō i ka hopena pale like iā EVOH akā ʻoi aku ka liʻiliʻi o nā mea ma muli o ke kaʻina hana hoʻolōʻihi like ʻana o ka LISIM, a ʻo ka mānoanoa o EHA he 15μm wale nō ka mea ʻoi aku ka maikaʻi. .
Eia hou, hiki ke hoʻopili ʻia ka hiki ke paʻi koʻikoʻi o EHA i nā hoʻopaʻa inoa pololei.Ke hoʻohālikelike ʻia me PVDC a i ʻole nā mea pale kiʻekiʻe, hiki iā EHA ke hoʻokō i nā kiko kiko liʻiliʻi maikaʻi loa.

ʻO EHAp kahi kiʻiʻoniʻoni ʻoniʻoni ʻoniʻoni a ʻalohilohi.Kūpaʻa ia i ka 85 ℃ paila a i ʻole 105 ℃ hoʻopiha wela, OTR haʻahaʻa ma mua o 2 CC/m2.d.atm.Ke hoʻohālikelike ʻia me nā kiʻi ʻoniʻoni BOPA maʻamau, ʻoi aku ka maikaʻi o ka hoʻokō ʻana o ka oxygen o EHAp, ʻoi aku ka maikaʻi o ka paʻi ʻana i koi ʻia i ka pale kinoea, e like me ka meaʻai holoholona, nā mea hoʻohuihui, nā pastries me ke ola pōkole pōkole, cheese, nā kīʻaha, nā mea inu waiu fermentative a me nā baluna kiʻekiʻe.
