ʻO nā waiwai hana o nā mea kiʻi paʻi kiʻi e alakaʻi pololei i ka hoʻomohala hana o nā mea hoʻopihapiha hoʻopihapiha hoʻopihapiha. ʻO kēia ka hoʻolauna pōkole i nā waiwai hana o kekahi mau mea hoʻohana maʻamau.
1. Mea hoʻohana maʻamau i hoʻohana ʻia: PE film
Ua hoʻololi ʻia nā mea PE wela-sealable mai nā kiʻi ʻoniʻoni hoʻokahi-layer blown a i nā kiʻiʻoniʻoni co-extruded multi-layer, i hiki ke hoʻolālā ʻia nā ʻano o nā papa o loko, waena a me waho. Hiki i ka hoʻolālā ʻano hui ʻana o nā ʻano resins polyethylene like ʻole ke hana i nā mahana hoʻopaʻa like ʻole, nā pae wela hoʻopaʻa ʻana i ka wela, nā ʻano mea hoʻopaʻapaʻa anti-sealing like ʻole,hnā ikaika adhesive, nā hopena anti-static, a me nā mea ʻē aʻe, e hoʻokō i nā koi kikoʻī huahana a me nā mea kiʻiʻoniʻoni PE me nā ʻano hana like ʻole.
I nā makahiki i hala iho nei, ua hoʻomohala ʻia nā kiʻiʻoniʻoni biaxially oriented polyethylene (BOPE), e hoʻomaikaʻi i ka ikaika tensile o nā kiʻiʻoniʻoni polyethylene a ʻoi aku ka ikaika o ka wela.
2. Mea Kiʻiʻoniʻoni CPP
Hoʻohana maʻamau ʻia nā mea CPP i BOPP / CPP i kēia ʻano hoʻopihapiha hoʻopihapiha hoʻomaʻamaʻa māmā, akā hiki ke hana ʻia nā ʻano hana like ʻole o ka resin CPP i nā ʻano hana like ʻole o ka kiʻiʻoniʻoni, e like me ka hoʻomaikaʻi ʻana i ka haʻahaʻa haʻahaʻa, ke kū ʻana i ka kuke wela kiʻekiʻe.
Ri nā makahiki i hala iho nei, ua hoʻomohala ka ʻoihana i kahi kiʻiʻoniʻoni matte CPP, e hoʻonui ana i ka hopena hōʻike ʻike o nā ʻeke kiʻi ʻoniʻoni CPP hoʻokahi.
3. Nā mea kiʻiʻoniʻoni BOPP
Hoʻohana pinepine ʻia ke kiʻi ʻoniʻoni puʻupuʻu māmā ʻo BOPP māmā kiʻi ʻoniʻoni a me BOPP matte film, aia pū kekahi BOPP heat sealing film (hoʻokahi ʻaoʻao a ʻelua ʻaoʻao wela wela), BOPP momi kiʻiʻoniʻoni.
Hōʻike ʻia ʻo BOPP e ka ikaika tensile kiʻekiʻe (kūpono no ka paʻi ʻana i nā kala he nui), maikaʻi nā waiwai pale wai wai, hoʻohana nui ʻia i loko o ka ʻeke kukui kūpaʻa o ka maka o ka mea i paʻi ʻia.
ʻO ke kiʻiʻoniʻoni matte BOPP me kahi hopena hoʻonaninani matte e like me ka pepa. Hiki ke hoʻohana ʻia ke kiʻi ʻoniʻoni hoʻopaʻa wela BOPP ma ke ʻano he mea hoʻopihapiha hoʻokahi-layer, e like me ke kāwili ʻana i ka ʻeke o loko o ka candy me. Hoʻohana nui ʻia ke kiʻi momi BOPP no ka paʻi ʻana i ka ice-cream paʻa wela sealing layer, hiki ke mālama i ka paʻi keʻokeʻo keʻokeʻo, kona haʻahaʻa haʻahaʻa, 2 a 3N / 15mm ikaika hoʻopaʻa ʻana i maʻalahi ka ʻeke e wehe i nā mea i loko.
Eia kekahi, e like me ka BOPP anti-fog film, holographic OPP laser film, PP synthetic paper, biodegradable BOPP film a me nā ʻano BOPP ʻē aʻe o nā kiʻiʻoniʻoni hana i kaulana a hoʻohana ʻia i kahi kikoʻī.
4. Mea hoʻohana maʻamau i hoʻohana ʻia: PET kiʻiʻoniʻoni
Hoʻohana nui ʻia ke kiʻi māmā 12MICRONS PET i loko o ka hoʻopili paʻa paʻa, ʻoi aku ka kiʻekiʻe o ka ikaika mechanical o kāna mau mea hoʻopihapiha laminated ma mua o nā huahana papalua papalua BOPP (haʻahaʻa haʻahaʻa ma mua o nā huahana hui pālua pālua BOPA), a me ka hiki ke pale oxygen o ka BOPP / PE (CPP) kiʻi ʻoniʻoni e hōʻemi i ka 20 a 30 mau manawa.
He maikaʻi loa ka pale wela o nā mea PET, a hiki ke hana i ka palahalaha o nā ʻeke maikaʻi. ke kiʻi ʻoniʻoni wela PET, kiʻi ʻoniʻoni wela PET PET, kiʻiʻoniʻoni matte PET, kiʻiʻoniʻoni polyester kiʻekiʻe, kiʻi ʻoniʻoni PET twist, kiʻiʻoniʻoni PET PET a me nā huahana hana ʻē aʻe.
5. Mea hoʻopili maʻamau: kiʻi nylon
Hoʻohana nui ʻia ʻo Biaxially oriented nylon film i loko o ka ʻeke, ka paila a me ka puhi ʻana i nā ʻeke no kona ikaika kiʻekiʻe, ke kūpaʻa puncture kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe a me ka pale oxygen ʻoi aku ka maikaʻi.
ʻO ka hapa nui o nā ʻeke laminated nui ma luna o 1.7kg e hoʻohana pū ana i ka hoʻolālā BOPA // PE no ke kūpaʻa hāʻule maikaʻi.
Kiʻi ʻoniʻoni nylon, hoʻohana nui ʻia ma Iapana no ka hoʻopili ʻana i ka meaʻai maloʻo, maikaʻi ke kūpaʻa haʻahaʻa haʻahaʻa, e hōʻemi ana i ka haki ʻana o ka ʻeke i ka wā haʻahaʻa haʻahaʻa haʻahaʻa a me ka lawe ʻana.
6. Maʻamau Packaging Material : Aluminum coating Metalized Film
Vacuum aluminizing i loko o ke kiʻiʻoniʻoni (e like me PET, BOPP, CPP, PE, PVC, etc.) ka ili o ka hoʻokumu 'ia o ka papa o ka dense alumini papa, pela e hoʻonui nui i ka kiʻiʻoniʻoni ma luna o ka wai mahu, oxygen, māmā pale kaha, ka mea i hoʻohana nuiʻia i ka composite flexible packaging VMPET, VMCPP mea.
ʻO VMPET no ka laminating ʻekolu-papa, VMCPP no ka laminating ʻelua-papa.
OPP // VMPET // Ua hoʻohana pono ʻia ka hoʻolālā PE i ka paʻi ʻana i nā lau ʻai, e ulu ana i nā huahana i loko o ka pahu paila kīwī. Ua hoʻohana pono ʻia ka hoʻolālā PE no ka ʻoki ʻana i nā mea kanu, nā hua hua i loko o ka pahu paila paila, i mea e lanakila ai i nā hemahema o nā huahana aluminized maʻamau, maʻalahi ka neʻe ʻana o ka papa alumini, mai pale i nā hemahema o ka paila ʻana, ka hoʻomohala ʻana o nā huahana VMPET me ke ʻano o ka uhi lalo, ma mua a ma hope o ka paila ʻana o ka peeling ikaika o ka 15mmrate ʻaʻole i hoʻonui i ka ikaika o ka alumini ma mua o 15mmrate. hana pale holoʻokoʻa o ka ʻeke.
7. Mea hoʻopili maʻamau: Aluminum foil
ʻO ka pahu alumini no ka hoʻopili maʻalahi he 6.5μm a i ʻole 9μm 12microns mānoanoa, alumini pepa mea theoretically he kiʻekiʻe keakea mea, ka wai permeability, oxygen permeability, malamalama permeability "0", akā, i ka mea, aia nā pinholes i loko o ka alumini pepa a me ka pelu ana i ka ilihune pinhole kū'ē, aia kekahi helu o ka maoli keakea pōʻai 'aʻole kūpono. ʻO ke kī i ka hoʻohana ʻana i ka alumini foil ka pale ʻana i nā pinholes i ka wā o ka hoʻoili ʻana, ka hoʻopili ʻana a me ka lawe ʻana, no laila e hōʻemi ana i ka hiki ke pale maoli. I nā makahiki i hala iho nei, aia kahi manaʻo o nā mea alumini alumini e hoʻololi ʻia e nā mea hoʻopihapiha hoʻokele waiwai i kā lākou mau wahi noi maʻamau.
8. Hoʻohana pinepine ʻia nā mea hoʻopihapiha: uhi ʻia nā kiʻiʻoniʻoni kiʻekiʻe
ʻO ke kiʻiʻoniʻoni i uhi ʻia ʻo PVDC (K coating film), PVA coated film (A coating film).
Loaʻa ka PVDC i ka pale oxygen maikaʻi a me ke kūpaʻa ʻana o ka wai, a he ʻike maikaʻi loa, uhi ʻia ʻo PVDC kiʻi i hoʻohana ʻia ma ke kiʻi kumu ʻo BOPP, BOPET, BOPA, CPP, a me nā mea ʻē aʻe, akā hiki ke PE, PVC, cellophane a me nā kiʻiʻoniʻoni ʻē aʻe, i ka hoʻopili paʻa paʻa i ka kiʻi ʻoniʻoni KOPP, KPET, KPA.
9. Mea hoʻopili maʻamau: Co-extruded High Barrier Films
ʻO ka co-extrusion he ʻelua a ʻoi aku paha nā plastics ʻokoʻa, ma o ʻelua a ʻoi aku paha ma mua o ʻelua extruders, i mea e hoʻoheheʻe ai nā ʻano plastics a hoʻoheheʻe ʻia no kahi poʻo make, ka hoʻomākaukau ʻana i nā kiʻi ʻoniʻoni o kahi ʻano hana. Hana pinepine ʻia nā kiʻi ʻoniʻoni ʻoniʻoni ʻoniʻoni i hoʻohui ʻia mai ka hui pū ʻana o nā plastics pale, polyolefin plastics a me nā resins adhesive o ʻekolu ʻano mea nui, ʻo nā resins pale ka nui o PA, EVOH, PVDC, etc.
ʻO ka mea i luna he mau mea hoʻopili maʻamau wale nō, ʻoiaʻiʻo, ma ka liʻiliʻi o ka hoʻohana ʻana i ka oxide vapor coating, PVC, PS, PEN, pepa, a me nā mea ʻē aʻe, a me ka resin like e like me nā ʻano hana like ʻole, hiki ke hana ʻia nā ʻano hana like ʻole ma o ka hoʻololi ʻana i nā waiwai hana like ʻole o ka mea kiʻiʻoniʻoni. ʻO ka lamination o nā kiʻiʻoniʻoni hana like ʻole, ma o ka lamination maloʻo, ka lamination me ka solvent-free, extrusion lamination a me nā ʻenehana hana ʻē aʻe e hana ai i nā mea hoʻopihapiha hoʻopihapiha kūpono e hoʻokō ai i nā pono o nā ʻano like ʻole.huahanakāʻei ʻana.
