Meaʻai Packaging Bag Material Introduction

ʻAʻole ʻike ka poʻe he aha ka meaʻeke ʻeke meaʻaihana ʻia maʻamau.E wehewehe pōkole ʻo Honest i nā mea oʻeke ʻeke meaʻais.

Mea hoʻopili meaʻai: PVDC (polyvinylidene chloride), PE (polyethylene), PP (polypropylene), PA (nylon), EVOH (ethylene/vinyl alcohol copolymer), aluminized film (aluminum + PE), etc. , kekahi mau membranes nui.
Hiki ke hoʻokaʻawale ʻia ka hana ʻana o ke kiʻiʻoniʻoni: kiʻi ʻoniʻoni, kiʻi puhi puhi.
I kēia manawa, ʻo nā mea nui i hoʻohana ʻia no ka hoʻopili meaʻai ʻo PP a me PE, ʻo ia hoʻi, polypropylene a me polyethylene plastics.No nā mea ʻelua, hiki ke māʻona i ka ʻeke meaʻai.
Ke hoʻohālikelike ʻia me ka ʻeke meaʻai ʻole, ʻaʻole i loaʻa i ka PP a me ka PE nā mea hoʻohui plastik.Ua ʻike mākou a pau he hopena nui ka plastic additives i ke kino o ke kanaka, ʻoi aku ka olakino o nā keiki.ʻAʻole hoʻokuʻu ʻo PP a me PE i nā mea ʻona i ka wā e hoʻohana ai.Hiki i kekahi mau mea 'ē a'e ke kumu i ka ma'i 'a'ai, akā 'a'ole na'e ka PP a me ka PE.Hoʻohana ʻia ka pāpaʻi PVC no ka paʻi kiʻiʻoniʻoni, akā ma muli o kona palekana ʻole, ua hoʻololi mālie ʻia e ka PE Cling Film.
ʻO nā hiʻohiʻona o ka PE: ʻoi aku ka palupalu, ʻoi aku ka maikaʻi o nā waiwai mechanical ma mua o ka PP, nā huahana i hōʻike ʻia me nā ʻeke kūʻai kūʻai kūʻai kūʻai, kāwele ʻōpala, ʻeke ʻōpala, a pēlā aku. nā waiwai, a ʻoi aku ka maikaʻi o ka hana wela ma mua o ka PE, ʻo ia ka mea i loaʻa i ka huahana nā ʻeke berena.
ʻO ka maʻamau e like me ka hoʻolālā waiwai, ʻo ka papa o loko ka PE a i ʻole CPP, ʻo ka papa waho ʻo PA, PET, ʻo ka waena paha ʻo EVOH a i ʻole PVDC, a me nā mea ʻē aʻe, a he kiʻi alumini a alumini paha kekahi.

ʻO ka PE a me ka CPP he mau waiwai hoʻopaʻa wela maikaʻi, ʻo ia hoʻi, maʻalahi lākou e sila.
ʻO PA a me PET ka paʻi paʻi maikaʻi a hiki ke hoʻohana ʻia i ka papa waho e paʻi i nā kiʻi nani.
Loaʻa i ka PVDC a me EVOH nā waiwai pale maikaʻi a pale i ka oxidation.
ʻO ke kiʻiʻoniʻoni aluminika a me ka alumini alumini he mau mea pale kukui maikaʻi a kūpono i nā huahana i kūpono ʻole i ka māmā.

Loaʻa nā waiwai like ʻole a me nā hoʻohana like ʻole.ʻO nā ʻeke ʻeke meaʻai maʻamau, ʻaʻole ia he mea hoʻokahi, akā he mau mea hoʻohuihui multi-layer, hiki ke hoʻohui ʻia me ʻelua papa, ʻekolu papa, ʻehā papa, etc.
Meaʻai maloʻoameaʻai hauhana ʻia me ka PET/PE.
ʻo kahi laʻana,kuke wela welahana ʻia me ka CPP composite nylon, a i ʻole nā ​​​​composites ʻē aʻe.
ʻO ka pahu ʻulaʻula o ka ham he mea hoʻokahi PVDC.
Pākē a me ke kokolekae hoʻohana maʻamau i ka pepa akaka/PP, pepa kraft/PE/AL/PE, AL/PE, etc.
