He aha ka hoʻokomo ʻana o ka plasticfilms?

Hōʻike nā kiʻi ʻoniʻoni i kahi papa kumu o nā mea polymeric i hōʻike ʻia e ko lākou ʻano lahilahi, maʻalahi a me kahi ākea ākea. Hana ʻia kēia mau mea ʻenehana ma o ka hoʻoili ʻana i nā resins polymer-i loaʻa mai ka ʻaila a i ʻole ka hoʻonui ʻia ʻana mai nā kumu hoʻololi hou ʻia-i loko o nā pepa mau me ka mānoanoa, ākea, a me nā waiwai mechanical. Ua ulu nui ka mākeke kiʻi kiʻiʻoniʻoni 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 a puni ka honua.

ʻO ka versatility o nā kiʻiʻoniʻoni plastik mai kā lākou hui kūʻokoʻa o nā waiwai: māmā akā paʻa, hiki ke maʻalahi akā ikaika, a ʻaʻohe a i ʻole opaque e pili ana i nā koi hoʻolālā. ʻO kēia mau hiʻohiʻona, i hui pū ʻia me nā kumukūʻai haʻahaʻa haʻahaʻa, ua hana i nā kiʻiʻoniʻoni plastik i mea nui loa ma nā wahi āpau o ka ʻoihana hou a me ke ola o kēlā me kēia lā. Mai ka mālama ʻana i ka meaʻai hou a hiki i ka ʻae ʻana i nā mea uila maʻalahi, lawelawe nā kiʻiʻoniʻoni plastik i nā hana i ʻike ʻole ʻia e nā mea hoʻohana hope akā koʻikoʻi i ka hana huahana a me ka hoʻomau.

ʻO nā holomua hou i ka ʻepekema waiwai ua hoʻonui i ka hiki o nā kiʻiʻoniʻoni plastik ma mua o kā lākou hana kuʻuna. Hoʻokomo ʻia nā mea hou i nā kiʻiʻoniʻoni e hoʻololi i nā waiwai i ka pane ʻana i ka hoʻoulu ʻia ʻana o ke kaiapuni, nā mea ʻokoʻa biodegradable i nā plastik maʻamau, a me nā kiʻiʻoniʻoni pale hana kiʻekiʻe me ka hiki ʻole o ka pale ʻana. I ka manawa like, ʻo ka ulu ʻana o nā hopohopo kaiapuni i hoʻoulu i ka hoʻomohala ʻana i nā ʻōnaehana recycling pani-loop a me nā mea kiʻiʻoniʻoni bio-based e mālama ana i ka hana ʻoiai e hōʻemi ana i ka hopena kaiaola.

He aha ke ʻano o ka kiʻiʻoniʻoni plastik?

Nā Kiʻiʻoniʻoni Nui

ʻO nā kiʻiʻoniʻoni polyethylene ka mea i hoʻohana nui ʻia o ka kiʻiʻoniʻoni plastik, ʻoi aku ma mua o 40% o ka nui o ka hoʻohana ʻana i nā kiʻiʻoniʻoni plastik. Nā ʻano nui a me nā ʻano o nā kiʻiʻoniʻoni polyethylene:

1. Kiʻiʻoniʻoni Polyethylene Haʻahaʻa (LDPE)

Hōʻike ʻia nā kiʻiʻoniʻoni LDPE e ko lākou hiki ke maʻalahi, ʻike ʻia, a me nā mea ʻawaʻawa ʻole, nā mea ʻala ʻole. Loaʻa iā lākou ke kūpaʻa wai maikaʻi, ka hoʻomaʻamaʻa ʻana i ka wai, a me ke kūpaʻa kemika, e kūpono ana iā lākou no ka hoʻopili ʻana i nā meaʻai, nā lāʻau lapaʻau, a me nā huahana hoʻohana i kēlā me kēia lā. Loaʻa i nā kiʻiʻoniʻoni LDPE nā waiwai hoʻopaʻa wela maikaʻi a hoʻohana pinepine ʻia e like me nā papa wela-seal i nā kiʻiʻoniʻoni composite. Eia nō naʻe, ʻaʻole maikaʻi lākou i ka wela wela a ʻaʻole kūpono no ka hoʻomoʻa kuke wela wela.

2. Kiʻiʻoniʻoni Polyethylene Kiʻekiʻe (HDPE)

ʻOi aku ka paʻakikī o nā kiʻiʻoniʻoni HDPE, semi-translucent, a me ke kala keʻokeʻo. Hōʻike lākou i ka ikaika tensile kiʻekiʻe, ka pale ʻana i ka wai, ka pale wela, a me ka pale ʻaila i hoʻohālikelike ʻia me LDPE. He kūpono ʻo HDPE no ka hoʻopili paʻa ʻana a me nā kiʻiʻoniʻoni ʻenehana akā he haʻahaʻa haʻahaʻa a me ka nani.

3. Linear Low-Density Polyethylene Film (LLDPE)

Hoʻohui nā kiʻi ʻoniʻoni LLDPE i ka maʻalahi o LDPE me ka ikaika o HDPE, e hāʻawi ana i nā waiwai kikoʻī maikaʻi loa a me ke kūpaʻa puncture. Hoʻohana nui ʻia lākou i nā kiʻiʻoniʻoni kikoʻī, nā kiʻi ʻoniʻoni a me nā kiʻi ʻoniʻoni, e hoʻolilo iā lākou i mea kūpono no ka hoʻopili ʻana i ka wikiwiki wikiwiki.

4. Kiʻiʻoniʻoni Polyethylene Haʻahaʻa Haʻahaʻa Haʻahaʻa Metallocene Linear (mLLDPE)

Hana ʻia nā kiʻi ʻoniʻoni mLLDPE me ka hoʻohana ʻana i nā mea hoʻoheheʻe metallocene a hāʻawi i ka ikaika hopena kiʻekiʻe, ka ikaika tensile yield, a me ka ʻike ʻoi aku ka maikaʻi ma mua o ka LLDPE maʻamau. Hāʻawi lākou i ka hōʻemi ʻana i ka mānoanoa kiʻiʻoniʻoni ma luna o 15%, a laila e hoʻohaʻahaʻa i nā kumukūʻai waiwai. Hoʻohana maʻamau ʻia ka mLLDPE i nā kiʻi ʻoniʻoni ʻōmaʻomaʻo, nā kiʻiʻoniʻoni puʻupuʻu kaumaha, nā kiʻiʻoniʻoni hōʻemi, a me nā mea hoʻopihapiha kiʻekiʻe.

Nā Kiʻiʻoniʻoni Palaki ʻē aʻe

1. Nā Kiʻiʻoniʻoni Polypropylene (PP): ʻIke ʻia no ko lākou wahi hoʻoheheʻe kiʻekiʻe (160-170 ° C), e kūpono iā lākou no nā noi hoʻopiha wela a me ka pale umauma microwave. Hāʻawi nā kiʻi ʻoniʻoni PP i ke kūpaʻa kemika maikaʻi loa a hoʻohana pinepine ʻia no ka hoʻopili ʻana i nā meaʻai meaʻai a me nā mea hoʻomaʻemaʻe sterilization wraps.

2. Nā Kiʻiʻoniʻoni Polyvinyl Chloride (PVC): Manaʻo ʻia no ka akaka a me ka hiki ke paʻi akā ke alo nei i ka emi ʻana o ka hoʻohana ʻana ma muli o nā hopohopo kaiapuni. ʻO nā noi i koe e komo pū me ka blister packaging a me kekahi mau kiʻiʻoniʻoni pili5.

3. Nā Kiʻiʻoniʻoni Polyester (PET): Ke hoʻokiʻekiʻe nei i ka ikaika tensile kiʻekiʻe a me ke kūpaʻa wela, pono pono nā kiʻi ʻoniʻoni PET no nā mea uila maʻalahi, nā lipine magnetic, a me ka pale ʻai meaʻai kiʻekiʻe. Hōʻike ʻia ka PET Biaxially-oriented (BOPET) i hoʻonui ʻia i nā waiwai mechanical a me nā mea pale.

Nā Kiʻiʻoniʻoni Polimer Kūikawā:

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

2. Polyvinylidene Chloride (PVDC): ʻO ka hoʻomaʻamaʻa maikaʻi a me ka hana pale oxygen

3. Polylactic Acid (PLA): Ke kū nei i ka bio-based ʻē aʻe me ka compostability, ʻoiai i kaupalena ʻia e ka brittleness—ua hoʻopuka nā holomua hou i nā kiʻiʻoniʻoni PLA maʻalahi ma o ka hoʻopili pololei ʻana i nā plasticizer polyether i loko o ke kaulahao polymer.

Nā ʻano hana kiʻiʻoniʻoni plastik

1. Blown Film Extrusion: ʻO ke kaʻina hana nui no nā kiʻiʻoniʻoni PE, kahi i hoʻoheheʻe ʻia ai ka polymer hehee ma o ka make pōʻai, hoʻoulu ʻia i loko o kahi ʻōpū, a hoʻomāʻalili e hana i kahi paipu e hiki ke hoʻopalapala ʻia i loko o ke kiʻi pālua. Hāʻawi kēia ʻano hana i nā waiwai mechanical kaulike ma nā ʻaoʻao ʻelua a me nā ʻaoʻao transverse.

2. Hoʻolele Kiʻiʻoniʻoni Kiʻiʻoniʻoni: Hoʻoheheʻe ʻia ka polymer melt ma o ka make palahalaha ma luna o kahi ʻōwili maloʻo, e hana ana i nā kiʻiʻoniʻoni me ka ʻokoʻa a me ka mānoanoa like ʻole. He mea maʻamau no nā kiʻiʻoniʻoni PP a me PET kahi i koʻikoʻi ai nā waiwai optical.

3. Calendering: Hoʻohana mua ʻia no nā kiʻiʻoniʻoni PVC, kahi i hoʻopili ʻia ai ka pūhui polymer ma o ke ʻano o nā wili wela e hoʻokō pono i ka mana mānoanoa. ʻO nā kiʻiʻoniʻoni calendered he ʻoi aku ka maikaʻi o ka hoʻopau ʻana i ka ʻili akā ʻaʻole liʻiliʻi nā waiwai mechanical like ʻole ma ka laula.

4. Hoʻoheheʻe ʻia ka hopena: Hoʻohana ʻia no nā kiʻiʻoniʻoni kūikawā kahi e pale ai i ka hoʻoheheʻe ʻana i ka hoʻoheheʻe. Hoʻoheheʻe ʻia ka polymer i ka solvent, hoʻolei ʻia ma ke kāʻei, a maloʻo e hana i ke kiʻiʻoniʻoni-maʻamau no kekahi mau kiʻiʻoniʻoni biodegradable a me nā noi membrane.

5. Biaxial Orientation: Hoʻopaneʻe ʻia nā kiʻiʻoniʻoni ma nā ʻaoʻao ʻelua a me nā ʻaoʻao ʻaoʻao, ma ke kaʻina (tenter frame) a i ka manawa like paha (ka hana ʻeleʻele), e hoʻomaikaʻi nui i ka ikaika, akaka, a me nā waiwai pale. ʻO nā kiʻiʻoniʻoni Biaxially-oriented PP (BOPP) a me PET (BOPET) nā kūlana ʻoihana no ka hoʻopili hana kiʻekiʻe.

Nā ʻano hou a me nā mea hou i loko o nā kiʻiʻoniʻoni plastik

Ke ulu nei ka ʻoihana kiʻiʻoniʻoni plastik, me ka manaʻo nui i ka hoʻomau, ka hana, a me ka pono. ʻO kekahi mau hiʻohiʻona kaulana:

1.PFAS-Free Slip Agents:ʻO nā mea hana paʻa paʻa 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 Hoʻomaka Hoʻomau: Ua hoʻopau maikaʻi nā ʻoihana e like me Fox Packaging i ka PFAS mai kā lākou mau koho hoʻopihapiha maʻalahi, e kūlike me nā ʻano hoʻoponopono ākea a me nā ʻoihana. Ua hoʻopaʻa ʻia ka US FDA i nā ʻōlelo hoʻohiki e hoʻoneʻe i ka PFAS mai ka ʻai ʻana i ka meaʻai, e hāʻawi ana i kahi hōʻemi nui o ka hōʻike PFAS meaʻai.

ʻO nā hoʻonā hou no ka PFAS-Free kōkua i nā kiʻiʻoniʻoni plastik mai SILIKE

Lawe ʻo SILIKE i kahi ʻano hana me kāna mau huahana SILIMER series, e hāʻawi ana i nā mea houPFAS-free polymer processing aids (PPAs). Hōʻike kēia laina huahana piha i ka 100% pure PFAS-free PPA, nā huahana PPA fluorine-free, a me ka PFAS-free, fluorine-free PPA masterbatches. Ma ka hoʻopau ʻana i ka pono o nā mea hoʻohui fluorine, hoʻomaikaʻi nui kēia mau huahana i ke kaʻina hana no LLDPE, LDPE, HDPE, mLLDPE, PP, a me nā huahana kiʻiʻoniʻoni. Hoʻopili lākou me nā hoʻoponopono kaiapuni hou aʻe e hoʻonui ana i ka pono hana, e hōʻemi ana i ka downtime, a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana holoʻokoʻa. Me ka SILIKE PFAS-free PPA e lawe mai i nā pono Huahana hope loa, me: ka hoʻopau ʻana i ka haʻihaʻi heheʻe (ʻili manō), hoʻomaikaʻi i ka maʻalahi, a me ka maikaʻi o ka ʻili.
