2. Nā Pōkole a me ka Hoʻolauna

AL - pepa alumini

ʻO ke kiʻiʻoniʻoni polyamide i kuhikuhi ʻia ma ke ʻano biaxially BOPA (NY)

ʻO ka ʻili polyester i hoʻonohonoho ʻia ma ke ʻano biaxially BOPET (PET)

ʻO ke kiʻiʻoniʻoni polypropylene i kuhikuhi ʻia ma ke ʻano biaxially BOPP

ʻO ke kiʻiʻoniʻoni polypropylene i hoʻolei ʻia CPP

ʻO ka palakiko vinyl-acrylic EAA

Palakiko EEAK ethylene-ethyl acrylate

Palakiko vinyl-methacrylic EMA

Palakiko EVAC ethylene-vinyl acetate

IONOMER Ionic Copolymer

ʻO ka polyethylene PE (hiki ke hoʻokomo pū ʻia me PE-LD, PE-LLD, PE-MLLD, PE-HD, PE i hoʻololi ʻia, a pēlā aku):

——PE-HD Polyethylene Density Kiʻekiʻe

——PE-LD Polyethylene haʻahaʻa haʻahaʻa

——PE-LLD polyethylene haʻahaʻa linear

——PE-MD polyethylene mānoanoa waena

ʻeke metala PE-MLLD polyethylene haʻahaʻa haʻahaʻa

PO polyolefin

Kelepaʻi PT

ʻO ka polypropylene hoʻolei ʻia i hoʻoheheʻe ʻia i ka vacuum VMCPP

ʻO ka polyester alumini hoʻoheheʻe ʻia ʻo VMPET

ʻO BOPP (OPP)——ʻili polypropylene i kuhikuhi ʻia i ke ʻano biaxially, ʻo ia ka ʻili i hana ʻia me ka polypropylene ma ke ʻano he mea maka nui a hoʻolōʻihi ʻia e ke ʻano ʻili pālahalaha. Loaʻa iā ia ka ikaika tensile kiʻekiʻe, ka paʻakikī kiʻekiʻe, a me ka transparency. Maikaʻi, ʻālohilohi maikaʻi, hana static haʻahaʻa, hana paʻi maikaʻi loa a me ka hoʻopili ʻana o ka uhi ʻana, nā waiwai mahu wai a me nā mea pale maikaʻi loa, no laila ua hoʻohana nui ʻia i nā ʻoihana hoʻopili like ʻole.

PE - Polyethylene. He resin thermoplastic ia i loaʻa ma o ka polymerization o ka ethylene. I loko o ka ʻoihana, hoʻokomo pū ia i nā copolymers o ka ethylene a me kahi liʻiliʻi o α-olefins. ʻAʻohe ʻala o ka Polyethylene, ʻaʻohe ʻawaʻawa, manaʻo like me ka wax, loaʻa iā ia ke kūpaʻa haʻahaʻa maikaʻi loa (hiki i ka mahana hana haʻahaʻa ke hiki i -100 ~ -70 ° C), kūpaʻa kemika maikaʻi, a hiki ke kū i ka hapa nui o ka waikawa a me ka alkali erosion (ʻaʻole kū i ka oxidation) ke ʻano o ka waikawa). ʻAʻole hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe maʻamau i ka mahana o ka lumi, haʻahaʻa ka omo wai, insulation uila maikaʻi loa.

ʻO CPP—ʻo ia hoʻi, ʻo ka ʻili polypropylene i hoʻolei ʻia, i ʻike ʻia hoʻi he ʻili polypropylene i hoʻolōʻihi ʻole ʻia, hiki ke hoʻokaʻawale ʻia i ka ʻili CPP maʻamau (General CPP, GCPP no ka pōkole) a me ka ʻili CPP i uhi ʻia me ka alumini (Metalize CPP, MCPP no ka pōkole) e like me nā hoʻohana like ʻole a me ka ʻili kuke CPP (Retort CPP, RCPP no ka pōkole), a pēlā aku.

ʻO VMPET - pili i ka ʻili polyester aluminized. Hoʻopili ʻia i ka ʻili pale ma luna o ka ʻōpala o ka meaʻai maloʻo a me ka meaʻai pupuhi e like me nā biscuits a me ka ʻōpala o waho o kekahi mau lāʻau lapaʻau a me nā mea hoʻonani.

Loaʻa i ka ʻili alumini nā ʻano like me ka ʻili plastik a me nā ʻano metala. ʻO ke kuleana o ka uhi alumini ma luna o ka ʻili o ka ʻili, ʻo ia ke pale ʻana i ka radiation ultraviolet, ʻaʻole wale ia e hoʻolōʻihi i ke ola o nā mea i loko, akā e hoʻomaikaʻi pū i ka ʻōlinolino o ka ʻili. , ua nui loa ka hoʻohana ʻana o ka ʻili alumini i loko o ka ʻōpala hui. I kēia manawa, hoʻohana nui ʻia ia i ka ʻōpala o nā meaʻai maloʻo a me nā mea ʻai puffed e like me nā biscuits, a me ka ʻōpala waho o kekahi mau lāʻau lapaʻau a me nā mea hoʻonani.

PET - ʻike ʻia hoʻi ʻo ia he kiʻiʻoniʻoni polyester pale wela kiʻekiʻe. Loaʻa iā ia nā waiwai kino maikaʻi loa, nā waiwai kemika a me ke kūpaʻa dimensional, transparency, a me ka hana hou ʻana, a hiki ke hoʻohana nui ʻia i ka hoʻopaʻa leo magnetic, nā mea photosensitive, nā mea uila, ka insulation uila, nā kiʻiʻoniʻoni ʻoihana, ka hoʻonaninani ʻōpala, ka pale pale, nā aniani optical Pale ʻili a me nā ʻoihana ʻē aʻe. Hoʻohālike kiʻiʻoniʻoni polyester pale wela kiʻekiʻe: FBDW (ʻeleʻele matte hoʻokahi ʻaoʻao) FBSW (ʻeleʻele matte ʻaoʻao pālua) Nā kikoʻī kiʻiʻoniʻoni polyester pale wela kiʻekiʻe Ka laulā o ka ʻōwili ke anawaena o ke kumu 38μm~250μm 500~1080mm 300mm~650mm 76mm(3〞), 152mm (6〞) Nānā: Hiki ke hana ʻia nā kikoʻī laulā e like me nā pono maoli. ʻO ka lōʻihi maʻamau o ka ʻōwili kiʻiʻoniʻoni he 3000m a i ʻole 6000 like me 25μm.

PE-LLD—ʻO ka Linear Low Density Polyethylene (LLDPE), nā ʻāpana keʻokeʻo waiū ʻaʻohe ʻawahia, ʻono ʻole, ʻala ʻole me ka nui o 0.918 ~ 0.935g/cm3. Ke hoʻohālikelike ʻia me ka LDPE, ʻoi aku ka kiʻekiʻe o ka mahana palupalu a me ka mahana heheʻe, a he mau pono o ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi, ka paʻakikī kiʻekiʻe, ke kūʻē i ka wela, a me ke kūʻē i ke anu. Loaʻa iā ia ke kūʻē maikaʻi i ka haki ʻana o ke kaiapuni, ka ikaika hopena, a me ke kūpaʻa. ʻO ka ikaika haehae a me nā waiwai ʻē aʻe, a hiki ke kūʻē i nā waikawa, alkalis, nā mea hoʻoheheʻe organik, a pēlā aku a hoʻohana nui ʻia ma nā kahua o ka ʻoihana, ka mahiʻai, ka lāʻau lapaʻau, ka hoʻomaʻemaʻe a me nā mea e pono ai i kēlā me kēia lā. ʻO ka resin linear low-density polyethylene (LLDPE), i ʻike ʻia ʻo ka polyethylene hanauna ʻekolu, he ikaika tensile, ikaika haehae, kūʻē i ka haki ʻana o ke kaiapuni, kūʻē i ka mahana haʻahaʻa, a ʻoi aku ka maikaʻi o ke kūʻē i ka wela a me ka puncture.

ʻO BOPA (NYLON) - ʻo ia ka pōkole Pelekane o ka ʻili Biaxially oriented polyamide (nylon). ʻO ka ʻili nylon Biaxially oriented (BOPA) kahi mea nui no ka hana ʻana o nā mea hoʻopili hui like ʻole, a ua lilo ia i mea hoʻopili ʻekolu nui loa ma hope o nā kiʻiʻoniʻoni BOPP a me BOPET.

ʻO ke kiʻi ʻoniʻoni Nylon (i kapa ʻia hoʻi ʻo PA) He kiʻi ʻoniʻoni paʻa loa ke kiʻi ʻoniʻoni Nylon me ka transparency maikaʻi, ka ʻōlinolino maikaʻi, ka ikaika tensile kiʻekiʻe a me ka ikaika tensile, a me ke kūpaʻa wela maikaʻi, ke kūpaʻa anu a me ke kūpaʻa aila. ʻO ke kūpaʻa maikaʻi i nā mea hoʻoheheʻe organik, ke kūpaʻa abrasion, ke kūpaʻa puncture, a me ka palupalu, ke kūpaʻa oxygen maikaʻi loa, akā ʻaʻole pale i ka mahu wai, ke komo ʻana o ka makū kiʻekiʻe, ka permeability makū, ka sila wela maikaʻi ʻole, kūpono no ka hoʻopili ʻana i nā mea paʻa, e like me ka meaʻai momona, nā huahana ʻiʻo, ka meaʻai palai, ka meaʻai i hoʻopaʻa ʻia i ka vacuum, ka meaʻai mahu, a pēlā aku.

Hoʻokumu kā mākou mau kiʻiʻoniʻoni a me nā laminates i kahi papa o ka insulation e mālama i kāu huahana mai kekahi pōʻino ke hoʻopili ʻia. Hoʻohana ʻia nā ʻano mea hoʻopili he nui e like me ka polyethylene, polyester, nylon, a me nā mea ʻē aʻe i helu ʻia ma lalo nei e hana i kēia pale laminate.
