He aha ka hoʻolauna ʻana o ka plasticfnā ʻilms?

Hōʻike nā kiʻiʻoniʻoni plastik i kahi papa kumu o nā mea polymeric i hōʻike ʻia e ko lākou ʻano lahilahi, palupalu a me ka ʻili ākea. Hana ʻia kēia mau mea i hana ʻia ma ka hana ʻana i nā resins polymer—i loaʻa mai ka petroleum a i ʻole mai nā kumu hou—i loko o nā pepa hoʻomau me ka mānoanoa, ka laulā, a me nā waiwai mechanical i kāohi pono ʻia. Ua ulu nui ka mākeke kiʻiʻoniʻoni plastik honua mai kona hoʻomaka ʻana i ka waena o ke kenekulia 20, me ka hana makahiki o kēia manawa ma mua o 100 miliona metric tons ma ka honua holoʻokoʻa.

ʻO ke ʻano maʻalahi o nā kiʻiʻoniʻoni plastik mai ko lākou hui pū ʻana o nā waiwai: māmā akā paʻa, palupalu akā ikaika, a moakaka a ʻaʻole paha e like me nā koi o ka hoʻohui ʻana. ʻO kēia mau ʻano, i hui pū ʻia me nā kumukūʻai hana haʻahaʻa, ua hana i nā kiʻiʻoniʻoni plastik i mea nui loa ma aneane kēlā me kēia ʻāpana o ka ʻoihana hou a me ke ola o kēlā me kēia lā. Mai ka mālama ʻana i ka hou o ka meaʻai a hiki i ka hiki ʻana i nā mea uila palupalu holomua, lawelawe nā kiʻiʻoniʻoni plastik i nā hana i ʻike pinepine ʻole ʻia e nā mea hoʻohana hope akā koʻikoʻi i ka hana huahana a me ke kūpaʻa.

Ua hoʻonui nā holomua hou i ka ʻepekema mea i nā hiki o nā kiʻiʻoniʻoni plastik ma mua o kā lākou mau hana kuʻuna. ʻO nā hana hou e pili ana i nā kiʻiʻoniʻoni e hoʻololi i nā waiwai ma muli o nā mea hoʻonāukiuki o ke kaiapuni, nā koho biodegradable i nā plastics maʻamau, a me nā kiʻiʻoniʻoni pale hana kiʻekiʻe me nā hiki palekana i manaʻo ʻole ʻia. I ka manawa like, ua hoʻoulu ka ulu ʻana o nā hopohopo kaiapuni i ka hoʻomohala ʻana o nā ʻōnaehana hana hou ʻana i ka loop pani a me nā mea kiʻiʻoniʻoni bio-based e mālama i ka hana me ka hōʻemi ʻana i ka hopena o ke kaiapuni.

He aha ke ʻano o ka ʻili plastik?

Nā Kiʻiʻoniʻoni Loa Loa

ʻO nā kiʻiʻoniʻoni polyethylene ka ʻano kiʻiʻoniʻoni plastik i hoʻohana nui ʻia, e helu ana ma mua o 40% o ka hoʻohana ʻana o ka ʻiliʻoni plastik. Nā ʻAno Nui a me nā ʻAno o nā Kiʻiʻoniʻoni Polyethylene:

1. ʻAʻahu Polyethylene Haʻahaʻa-Density (LDPE)

ʻIke ʻia nā kiʻiʻoniʻoni LDPE e ko lākou palupalu, ʻike maopopo, a me nā waiwai ʻawaʻawa ʻole a ʻala ʻole. Loaʻa iā lākou ke kūpaʻa wai maikaʻi loa, ka pale ʻana i ka makū, a me ke kūpaʻa kemika, e kūpono ai no ka hoʻopili ʻana i ka meaʻai, nā lāʻau lapaʻau, a me nā huahana hoʻohana i kēlā me kēia lā. Loaʻa i nā kiʻiʻoniʻoni LDPE nā waiwai sila wela maikaʻi a hoʻohana pinepine ʻia e like me nā papa sila wela i nā kiʻiʻoniʻoni hui. Eia nō naʻe, he kūpaʻa wela maikaʻi ʻole ko lākou a ʻaʻole kūpono no ka hoʻopili kuke wela kiʻekiʻe.

2. ʻAila Polyethylene Kiʻekiʻe-Density (HDPE)

ʻOi aku ka paʻakikī o nā kiʻiʻoniʻoni HDPE, semi-translucent, a keʻokeʻo ke kala. Hōʻike lākou i ka ikaika tensile kiʻekiʻe, ke kūpaʻa i ka makū, ke kūpaʻa wela, a me ke kūpaʻa ʻaila i hoʻohālikelike ʻia me LDPE. He kūpono ʻo HDPE no nā ʻōpala paʻa a me nā kiʻiʻoniʻoni ʻoihana akā he haʻahaʻa ka transparency a me ka gloss.

3. ʻO ka Linear Low-Density Polyethylene Film (LLDPE)

Hoʻohui nā kiʻiʻoniʻoni LLDPE i ka maʻalahi o ka LDPE me ka ikaika o HDPE, e hāʻawi ana i nā waiwai hoʻolōʻihi maikaʻi loa a me ke kū'ē ʻana i ka puncture. Hoʻohana nui ʻia lākou i nā kiʻiʻoniʻoni hoʻolōʻihi, nā kiʻiʻoniʻoni hoʻēmi, a me nā kiʻiʻoniʻoni wahī, e kūpono ai no ka hoʻopili ʻakomi wikiwiki.

4. ʻO ka Metallocene Linear Low-Density Polyethylene Film (mLLDPE)

Hana ʻia nā kiʻiʻoniʻoni mLLDPE me ka hoʻohana ʻana i nā mea hoʻouluulu metallocene a hāʻawi i ka ikaika hopena kiʻekiʻe, ka ikaika tensile yield, a me ka transparency ʻoi aku ka maikaʻi ma mua o ka LLDPE maʻamau. ʻAe lākou i ka hōʻemi ʻana i ka mānoanoa o ke kiʻiʻoniʻoni ma mua o 15%, no laila e hoʻohaʻahaʻa ana i nā kumukūʻai mea. Hoʻohana pinepine ʻia ka mLLDPE i nā kiʻiʻoniʻoni hale kōmahana, nā kiʻiʻoniʻoni hoʻopili kaumaha, nā kiʻiʻoniʻoni hoʻēmi, a me nā mea hoʻopili kiʻekiʻe.

Nā Kiʻiʻoniʻoni Plastik ʻē aʻe

1. Nā Kiʻiʻoniʻoni Polypropylene (PP): Kaulana no ko lākou kiko heheʻe kiʻekiʻe (160-170°C), e kūpono ai no nā noi hoʻopiha wela a me ka hoʻopili palekana microwave. Hāʻawi nā kiʻiʻoniʻoni PP i ke kūpaʻa kemika maikaʻi loa a hoʻohana pinepine ʻia no ka hoʻopili ʻana i nā meaʻai māmā a me nā ʻōwili sterilization hāmeʻa lapaʻau.

2. Nā Kiʻiʻoniʻoni Polyvinyl Chloride (PVC): Kūpono ʻia no ka moakāka loa a me ka hiki ke paʻi ʻia akā ke kū nei i ka emi ʻana o ka hoʻohana ʻana ma muli o nā hopohopo e pili ana i ke kaiapuni. ʻO nā noi i koe e pili ana i ka pōpō blister a me kekahi mau kiʻiʻoniʻoni cling5.

3. Nā Kiʻiʻoniʻoni Polyester (PET): Me ka ikaika tensile kiʻekiʻe a me ke kūpaʻa wela, he mea pono nā kiʻiʻoniʻoni PET no nā mea uila maʻalahi, nā lipine magnetic, a me nā ʻōpala meaʻai pale kiʻekiʻe. Hōʻike ka PET Biaxially-oriented (BOPET) i nā waiwai mechanical a me nā pale i hoʻonui ʻia.

Nā Kiʻiʻoniʻoni Polymer Kūikawā:

1. Polyamide (Nylon): Nā waiwai pale oxygen kūikawā no ka mālama ʻana i ka meaʻai

2. Polyvinylidene Chloride (PVDC): Hana maikaʻi loa no ka pale ʻana i ka makū a me ka oxygen

3. Waikawa Polylactic (PLA): Ke koho ʻē aʻe e pili ana i ka bio me ka compostability, ʻoiai ua kaupalena ʻia e ka brittleness—ua hana nā holomua hou i nā kiʻiʻoniʻoni PLA maʻalahi ma ka hoʻohui ʻana i nā plasticizers polyether pololei i loko o ke kaulahao polymer.

Nā ʻAno Hana Hana Kiʻiʻoniʻoni Palakiko

1. Hoʻopuka ʻana i ka ʻili puhi: ʻO ke kaʻina hana nui no nā ʻili PE, kahi e hoʻopuka ʻia ai ka polymer i hoʻoheheʻe ʻia ma o kahi make poepoe, hoʻopiha ʻia i loko o kahi pehu, a hoʻomaʻalili ʻia e hana i kahi paipu hiki ke hoʻopalahalaha ʻia i loko o kahi ʻili pālua. Hāʻawi kēia ʻano hana i nā waiwai mechanical kaulike ma nā ʻaoʻao mīkini a me nā ʻaoʻao transverse.

2. Hoʻopuka ʻana i ka ʻiliʻili i hoʻolei ʻia: Hoʻopuka ʻia ka polymer heat ma o kahi make pālahalaha ma luna o kahi ʻōwili anuanu, e hana ana i nā ʻiliʻili me ka moakāka loa a me ka mānoanoa like. He mea maʻamau no nā ʻiliʻili PP a me PET kahi e koʻikoʻi ai nā waiwai optical.

3. Calendering: Hoʻohana nui ʻia no nā kiʻiʻoniʻoni PVC, kahi e hoʻokomo ʻia ai ka hui polymer ma o kahi moʻo o nā wili wela e hoʻokō ai i ka kaohi mānoanoa pololei. ʻOi aku ka maikaʻi o ka hoʻopau ʻana o ka ʻili i nā kiʻiʻoniʻoni calendering akā ʻaʻole like nā waiwai mechanical ma ka laulā.

4. Hoʻoheheʻe ʻana i ka hopena: Hoʻohana ʻia no nā kiʻiʻoniʻoni kūikawā kahi e pale ai ka like ʻana o ka like a i ʻole ka ʻike wela i ka hana hoʻoheheʻe. Hoʻoheheʻe ʻia ka polymer i loko o ka mea hoʻoheheʻe, hoʻolei ʻia ma luna o ke kāʻei, a hoʻomaloʻo ʻia e hana i kahi kiʻiʻoniʻoni—maʻamau no kekahi mau kiʻiʻoniʻoni biodegradable a me nā noi membrane.

5. Hoʻonohonoho Biaxial: Hoʻolōʻihi ʻia nā kiʻiʻoniʻoni ma nā ʻaoʻao mīkini a me nā ʻaoʻao transverse, ma ke ʻano he kaʻina (tenter frame) a i ʻole i ka manawa like (kaʻina hana pehu), e hoʻomaikaʻi nui ana i ka ikaika, ka maopopo, a me nā waiwai pale. ʻO nā kiʻiʻoniʻoni Biaxially-oriented PP (BOPP) a me PET (BOPET) nā kūlana ʻoihana no ka hoʻopili ʻana i ka hana kiʻekiʻe.

Nā ʻAno Hou a me nā Hana Hou i nā Kiʻiʻoniʻoni Plastic

Ke holomua nei ka ʻoihana kiʻiʻoniʻoni plastik, me ka manaʻo nui i ka hoʻomau, ka hana, a me ka pono. ʻO kekahi mau ʻano koʻikoʻi:

1.Nā mea hoʻoheheʻe ʻole PFAS:Nā mea hoʻoheheʻe hoʻomau e pale aku i nā mea per- a me polyfluoroalkyl (PFAS), e hoʻoponopono ana i nā pono hana a me nā hopohopo kaiapuni.

2. Nā Hana Hoʻomau: Ua hoʻopau pono nā ʻoihana e like me Fox Packaging i ka PFAS mai kā lākou mau koho hoʻopili maʻalahi āpau, e kūlike ana me nā ʻano hoʻoponopono ākea a me nā ʻano ʻoihana. Ua hoʻopaʻa ka US FDA i nā kuleana manawaleʻa e wehe i ka PFAS mai ka ʻōpala meaʻai, e kōkua ana i ka hōʻemi nui ʻana i ka hōʻike ʻana i ka PFAS i ka meaʻai.

Kōkua nā hoʻonā hou no ka hana ʻana me ka ʻole o ka PFAS i nā ʻiliʻili plastik mai SILIKE

Lawe ʻo SILIKE i kahi ala proactive me kāna mau huahana moʻo SILIMER, e hāʻawi ana i nā mea houNā mea kōkua hana polymer ʻole PFAS (PPAs)). Hōʻike kēia laina huahana piha i nā PPA maʻemaʻe ʻole PFAS 100%, nā huahana PPA fluorine-free, a me nā masterbatches PPA fluorine-free, fluorine-free. Ma ka hoʻopau ʻana i ka pono no nā mea hoʻohui fluorine, hoʻonui nui kēia mau huahana i ke kaʻina hana no LLDPE, LDPE, HDPE, mLLDPE, PP, a me nā huahana kiʻiʻoniʻoni. Hoʻohālikelike lākou me nā lula kaiapuni hou loa me ka hoʻonui ʻana i ka pono hana, ka hoʻemi ʻana i ka downtime, a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana holoʻokoʻa. Me SILIKE PFAS-free PPA e lawe mai i nā pono o ka Huahana hope loa, me: ka hoʻopau ʻana i ka haki heheʻe (ʻili mano), ka laumania i hoʻonui ʻia, a me ka maikaʻi o ka ʻili.
