Hoʻohana ka kiʻi ʻoniʻoni PP maʻamau i ka hoʻoheheʻe ʻana, ka hana maʻalahi a me ke kumukūʻai haʻahaʻa, akā ʻoi aku ka haʻahaʻa o ka hana optical ma mua o CPP a me BOPP.ʻO ka hiʻohiʻona nui o ka PP he kiʻekiʻe ka pale wela (e pili ana i -20 ° C ~ 120 ° C), a ʻo ka helu hoʻoheheʻe he kiʻekiʻe e like me 167 ° C, kahi kūpono no ka hoʻopiha ʻana i ka waiū soy, ka waiū laiki a me nā huahana ʻē aʻe e pono ai ka disinfection mahu. .ʻOi aku ka kiʻekiʻe o kona paʻakikī ma mua o ka PE, ka mea i hoʻohana ʻia e hana i nā pahu pahu, a ʻo ka hōʻailona waiwai ʻo No. ʻoiai ʻo ka PE he ʻoi aku ke kaumaha o ke kukui kukui.
4. Kiʻiʻoniʻoni Polyester (PET)
ʻO ke kiʻiʻoniʻoni polyester (PET) kahi mea ʻenehana thermoplastic.ʻO nā mea kiʻiʻoniʻoni lahilahi i hana ʻia me ka pepa mānoanoa e ke ʻano extrusion a me ka hoʻolōʻihi bidirectional.Hōʻike ʻia ke kiʻi ʻoniʻoni polyester e nā waiwai mechanical maikaʻi loa, rigidity kiʻekiʻe, paʻakikī a paʻakikī, kūpaʻa puncture, kūʻē friction, kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, kūpaʻa kemika, kūpaʻa aila, paʻa ʻana o ka ea a me ka mālama ʻala maikaʻi, ʻo ia kekahi o ka mea maʻamau i hoʻohana ʻia i ka permeability resistance composite. nā substrates kiʻiʻoniʻoni, akā ʻilihune ka pale ʻana o ka corona, kiʻekiʻe ke kumukūʻai.ʻO ka mānoanoa o ka kiʻiʻoniʻoni he 0.12mm maʻamau, ka mea maʻamau i hoʻohana ʻia e like me ka mea i waho o ka ʻeke ʻeke meaʻai paʻi, a maikaʻi ka paʻi.E kaha i ka hōʻailona waiwai 1 i loko o ka huahana plastik.
5. Nylon (PA)
ʻO ke kiʻi ʻoniʻoni ʻoniʻoni ʻo Nylon (polyamide PA) i kēia manawa ka hana ʻenehana o nā ʻano like ʻole, ʻo ia nā ʻano nui i hoʻohana ʻia e hana kiʻiʻoniʻoni ʻo ka nylon 6, nylon 12, nylon 66 a pēlā aku.ʻO ke kiʻi ʻoniʻoni ʻo Nylon kahi kiʻiʻoniʻoni paʻakikī loa, ʻike maopopo maikaʻi, a loaʻa i ka luster maikaʻi.ʻO ka ikaika tensile, ka ikaika tensile, ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ka pale ʻana i ka aila, ke kūpaʻa ʻana o ka mea hoʻoheheʻe kūlohelohe, ke kūpaʻa a me ke kūpaʻa puncture maikaʻi loa, a he palupalu ke kiʻiʻoniʻoni, kūpaʻa oxygen maikaʻi loa, akā maikaʻi ʻole ka pale ʻana o ka wai, ka hoʻoheheʻe ʻana o ka wai, nui ka moisture permeability, a ʻilihune ka hoʻopaʻa ʻana i ka wela.He kūpono no ka hoʻopaʻa ʻana i nā waiwai paʻakikī, e like me ka meaʻai momona, ka meaʻai palai, ka meaʻai hoʻomoʻa wai, ka meaʻai kuke, etc.
6. Polyethylene Kiekie (HDPE)
Kapa ʻia ke kiʻi ʻoniʻoni HDPE he geomembrane a i ʻole ke kiʻi impermeable.ʻO kona helu hoʻoheheʻe ʻana ma kahi o 110 ℃-130 ℃, a ʻo kona mānoanoa pili he 0.918-0.965kg/cm3.He crystallinity kiʻekiʻe, non-polar thermoplastic resin, ʻo ke ʻano HDPE maoli he keʻokeʻo keʻokeʻo, ma kahi ʻāpana liʻiliʻi o kahi degere o ka translucent.Loaʻa iā ia ke kū'ē maikaʻi i nā wela kiʻekiʻe a me nā haʻahaʻa haʻahaʻa a me ka hopena o ka hopena, ʻoiai ma -40F haʻahaʻa haʻahaʻa.ʻO kona kūpaʻa paʻa, rigidity, paʻakikī, ikaika mechanical, waimaka ikaika waiwai maikaʻi loa, a me ka piʻi ʻana o ka density, nā waiwai mechanical, nā mea pale, ka ikaika tensile a me ka pale wela e hoʻomaikaʻi ʻia e like me ia, hiki ke pale aku i ka waikawa, alkali, nā mea hoʻoheheʻe organik a me nā mea ʻē aʻe. ʻinoʻino.ʻIke: ʻo ka hapa nui opaque, manaʻo e like me ka wax, ʻeke ʻeke ʻeke a ʻānai paha i ka wā e kulu ai.
7. Polyethylene Density Haʻahaʻa (LDPE)
He haʻahaʻa ka haʻahaʻa kiʻiʻoniʻoni LDPE, palupalu, haʻahaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ke kūpaʻa kemika, ma lalo o nā kūlana maʻamau ka waikawa (koe ka waikawa oxidizing ikaika), ka alkali, ka paʻakai paʻakai, me ka insulation uila maikaʻi.Hoʻohana nui ʻia ʻo LDPE i nā ʻeke plastik, e kaha ana i ka hōʻailona waiwai ʻo No.ʻIke: ʻOi aku ka palupalu o ka ʻeke plastik i hana ʻia me LDPE, ʻoi aku ka liʻiliʻi o ka rustling i ka wā e kāwili ʻia ai, ʻo ke kiʻi ʻoniʻoni i waho o waho he palupalu a maʻalahi hoʻi e haehae i ka LDPE, a ʻoi aku ka palupalu a me ka paʻakikī ʻo PVC a i ʻole PP film.
8. Ka waiʻona Polyvinyl (PVA)
ʻO ka polyvinyl alcohol (PVA) kiʻiʻoniʻoni kiʻi paʻi kiʻekiʻe he kiʻiʻoniʻoni me ka waiwai pale kiʻekiʻe i hoʻokumu ʻia e ka uhi ʻana i ka wai hoʻoheheʻe wai i hoʻololi ʻia o ka waiʻona polyvinyl ma ka substrate o ka plastic polyethylene.No ka mea ʻo ke kiʻi ʻoniʻoni kiʻekiʻe o ka polyvinyl alcohol he mau mea pale maikaʻi a hoʻokō i nā koi o ka pale ʻana i ke kaiapuni, ʻoi aku ka maikaʻi o ka mākeke o kēia mea hoʻopihapiha, a aia kahi ākea ākea i ka ʻoihana meaʻai.
9. Kiʻiʻoniʻoni polypropylene (CPP)
ʻO ka hoʻolei polypropylene kiʻiʻoniʻoni (CPP) he ʻano kiʻi ʻoniʻoni hoʻoheheʻe ʻole ʻia e hoʻoheheʻe ʻia e hoʻoheheʻe ʻia e hoʻoheheʻe ʻia.Hōʻike ʻia ʻo ia e ka wikiwiki hana wikiwiki, kiʻekiʻe ka hopena, ke aniani kiʻiʻoniʻoni, ʻālohilohi, waiwai pale, palupalu, ʻano like ʻole o ka mānoanoa, hiki ke kū i ka kuke wela kiʻekiʻe (ka mahana kuke ma luna o 120 ° C) a me ka hoʻopaʻa ʻana i ka wela haʻahaʻa. 125 ° C), maikaʻi ke kaulike hana.ʻO ka hana ukali e like me ka paʻi ʻana, ʻoluʻolu ka composite, hoʻohana nui ʻia i nā textiles, nā meaʻai, nā mea e pono ai i kēlā me kēia lā, hana i ka substrate o loko o ka composite packaging, hiki ke hoʻolōʻihi i ke ola o ka meaʻai, hoʻonui i ka nani.
10. Bidirectional polypropylene film (BOPP)
ʻO ke kiʻi ʻoniʻoni polypropylene Biaxial (BOPP) he ʻeke ʻeke ʻeke hiki ke hoʻololi ʻia i hoʻomohala ʻia i ka makahiki 1960, kahi laina hana kūikawā e hoʻohui i nā mea waiwai polypropylene a me nā mea hoʻohui hana, hoʻoheheʻe a hui ʻia, hana i nā ʻāpana, a laila hana i kahi kiʻiʻoniʻoni ma ke kau ʻana.ʻO kēia kiʻiʻoniʻoni ʻaʻole wale ka maikaʻi o ka haʻahaʻa haʻahaʻa, ke kūpaʻa corrosion a me ka pale wela maikaʻi o ka resin PP kumu, akā loaʻa nō hoʻi nā waiwai optical maikaʻi, ikaika mechanical kiʻekiʻe, nā kumu waiwai waiwai, nā waiwai paʻi maikaʻi loa, a hiki ke hui pū ʻia me ka pepa, PET a me nā mea ʻē aʻe.Me ka wehewehe kiʻekiʻe a me ka nani, ka ink absorption maikaʻi a me ka hoʻopili ʻana i ka uhi ʻana, ka ikaika tensile kiʻekiʻe, nā waiwai pale aila maikaʻi loa, nā hiʻohiʻona electrostatic haʻahaʻa.
11. Kiʻiʻoniʻoni metala
ʻO ke kiʻiʻoniʻoni metalized nā hiʻohiʻona o ka kiʻiʻoniʻoni plastik a me ka metala.ʻO ke kuleana o ka pale alumini ma ka ʻili o ka kiʻiʻoniʻoni ʻo ia ka pale ʻana i ka mālamalama a pale i ka radiation ultraviolet, kahi e hoʻonui ai i ke ola o nā mea i loko a hoʻomaikaʻi i ka ʻōlinolino o ke kiʻiʻoniʻoni, e hoʻololi ana i ka alumini foil i kekahi ʻano, a he mea maʻalahi hoʻi. nani a maikaʻi nā mea pale.No laila, hoʻohana nui ʻia ke kiʻiʻoniʻoni metala i loko o ka hoʻopili composite, hoʻohana nui ʻia i nā kuki a me nā mea maloʻo ʻē aʻe, puffed food packaging, lāʻau lapaʻau a me nā mea hoʻonaninani.
