Ua ʻoi aku ka maikaʻi o ka PP ma mua o ka PET Moisture Barrier?

Ka Nīnau Paʻa Wai

No nā poʻe loea e koho ana i nā mea strapping a i ʻole nā ​​​​mea kiʻiʻoniʻoni, hiki ke noʻonoʻo koʻikoʻi ka hoʻokō ʻana i ka pale pale. ʻO nā huahana i mālama ʻia i loko o nā wahi haʻahaʻa, hoʻouna ʻia ma nā ʻāpana o ke aniau, a i ʻole i hoʻopaʻa ʻia me nā waiwai pili i ka moisture e pono ai i ka hoʻopaʻa ʻana e pale i ka makū. Ke hāpai nei kēia i kahi nīnau maʻamau: ʻoi aku ka maikaʻi o ke kaula PP ma mua o ka PET ma ke ʻano he pale wai? I ka hoʻohālikelike ʻana i ka nui o ka hoʻouna ʻana i ka mahu wai, hōʻike ka ʻikepili i ka hāʻawi ʻana o ke kiʻiʻoniʻoni polypropylene (OPP) oriented ma kahi o 5.4 mau manawa ʻoi aku ka maikaʻi o ka hana pale ʻana ma mua o ka PET o ka mānoanoa like. ʻO ka hoʻomaopopo ʻana i kēia mau ʻokoʻa waiwai e kōkua i ka poʻe ʻoihana kūʻai e koho i nā mea hoʻopihapiha kūpono no kā lākou noi kikoʻī.

Ma Jushuo Packaging , loaʻa pinepine mākou i kēia nīnau mai nā mea kūʻai aku e loiloi ana ʻO ke kaula PP no nā noi kahi e hopohopo ai ka ʻike wai. Ke hōʻoia nei kā mākou ʻikepili hana ʻana i ka pale ʻana o ka maʻa maʻemaʻe o ke kaula PP-ʻo ia ka hopena o kāna ʻano molekole non-polar—e kūpono ia no ka mālama ʻana i waho, ka mahiʻai, a me nā noi hoʻonaʻauao.

1. ʻAi Pahu: Ka ʻikepili

1.1 Hoʻohālikelike Hana Paʻa

Hāʻawi ʻia nā ʻikepili hoʻāʻo i paʻi ʻia i kahi pane maopopo i ka nīnau pale ʻūlū. Wahi a ka hoʻāʻo kūʻokoʻa e hoʻohālikelike ana i nā kiʻi ʻoniʻoni ʻoniʻoni polypropylene (OPP) o ka mānoanoa like, ua hōʻike ʻo BOPP i ka ʻoi aku ka maikaʻi o ka hana ʻana i ka pale mahu wai :

Hōʻike ka ʻikepili i ka 5.4 mau manawa haʻahaʻa o ka hoʻoili ʻana o ka mahu wai o BOPP ma mua o PET, e hōʻike ana i ka hana ʻoi aku ka maikaʻi. Ua hōʻoia nā kumu ʻoihana ʻoi aku ka maikaʻi o ka pale ʻana o ka polypropylene ma kahi o 3 mau manawa ma mua o ka PET . ʻO ka ʻokoʻa o nā waiwai pahū wai e pili ana i nā ʻokoʻa o ka polarity molecular polymer .

1.2 No ke aha he ʻoi aku ka maikaʻi o ka pale ʻana o ka wai

ʻO ka pale wai ʻoi aku ka maikaʻi o ka PP i hoʻohālikelike ʻia me PET pili i ka kemika polymer. ʻO ka PP kahi polymer hydrocarbon non-polar me ka haʻahaʻa haʻahaʻa no nā molekele wai, e hopena i ka haʻahaʻa haʻahaʻa haʻahaʻa. Loaʻa i ka PET nā pūʻulu ester i ʻoi aku ka polarity kiʻekiʻe, e hana ana i nā wahi pili hou aku no nā molekole wai e hele i loko o ka hale polymer. .

Wahi a ka palapala ʻepekema hoʻopaʻa ʻana, ʻoi aku ka maikaʻi o ka hana ʻana o ka wai wai o nā polyolefins e like me PP ma mua o nā polyesters e like me PET ma muli o ko lākou ʻano hydrophobic a me ka haʻahaʻa haʻahaʻa haʻahaʻa no ka diffusion mole wai.

2. Ke Kiʻi Paʻa Paʻa

2.1 Pale Oxygen: Ka ikaika o PET

ʻOiai ʻoi aku ka maikaʻi o ka PP ma ke ʻano he pale wai, hāʻawi ʻo PET i kahi pono ʻokoʻa: ʻoi aku ka pale oxygen. Hōʻike ka ʻikepili hoʻāʻo like i ka nui o ka hoʻouna oxygen o PET ma kahi o 23 mau manawa haʻahaʻa ma mua o BOPP . ʻO kēia ka PET i koho maikaʻi ʻia no nā noi kahi i hoʻokomo ʻia ai ka oxygen ka mea e hopohopo nui ai—e like me ka hoʻopili ʻana i nā meaʻai e koi ana i ke ola lōʻihi.

2.2 Hōʻuluʻulu Paʻa

ʻO kēia pilina ʻokoʻa ma waena o ka makū a me ka pale oxygen he mea kaulana i ka ʻepekema polymer packaging - ʻoi aku nā mea like ʻole i nā ʻano pale pale like ʻole.

3. Nā hopena no ke koho ʻana i ke kaula PP

3.1 I ka wā e pono ai ka pale ʻana i ka wai no ka hoʻopaʻa ʻana

No ka hapa nui o nā noi kāʻei PP, ʻaʻole ʻo ka mea pale ka mea koho mua. Hoʻohana maʻamau ʻia ʻo Strapping e hoʻopaʻa i nā ukana ma mua o ka hāʻawi ʻana i ka pale pale. Eia nō naʻe, i kekahi mau hiʻohiʻona, kūpono ke kūpaʻa o ka makū:

• ʻO ka waiho ʻana i waho: ʻO ke kūpaʻa ʻana o ke kaula o PP e kōkua i ka mālama ʻana i ka hana ma nā kūlana haʻahaʻa a pulu paha

• Nā noi kaulahao anu: Hiki ke hoʻopili i ka wai mai ka condensation i ke kaula a me ka pololei

• Hoʻopili mahiʻai: Hoʻopaʻa pinepine ʻia ka hay, ka pulupulu, a me nā huahana mahiʻai ʻē aʻe ma waho

Hāʻawi ʻo Jushuo Packaging's PP strap i ka pale ʻana i ka wai ma ke ʻano he ʻāpana o kāna mau waiwai waiwai, e kūpono ana i kēia mau noi koi.

3.2 Alakaʻi Koho Mea

No nā poʻe loea e koho ana i nā mea strapping:

Hōʻuluʻulu manaʻo

Ua ʻoi aku ka maikaʻi o ka PP ma mua o ka PET ma ke ʻano he pale wai? Hōʻoia ka ʻikepili: ʻae, hāʻawi ʻo PP i ka hana ʻoi aku ka maikaʻi. Ma kahi o 5.4 mau manawa haʻahaʻa ka nui o ka hoʻoili ʻana o ka mahu wai kiʻi BOPP ma mua o PET, e hana ana iā PP ka lanakila maʻemaʻe no nā noi e koi ana i ka pale ʻana i ka wai. Eia naʻe, ʻoi aku ka nui o ke kiʻi pale: ʻoi aku ka PET ma ke ʻano he pale oxygen, me ka hana ma kahi o 23 mau manawa ʻoi aku ka maikaʻi ma mua o PP.

No ka hoʻopaʻa ʻana, ʻaʻole maʻamau ka pale maʻamau ka mea koho mua, akā ʻo ke kūpaʻa ʻana o ka moisture kūʻokoʻa o PP - ka hopena o kāna ʻano hydrocarbon non-polar - kūpono ia no ka mālama ʻana i waho, ka mahiʻai, a me nā noi hoʻomehana honua. Ke koho ʻana ma waena o ke kaula PP a me PET, e noʻonoʻo i nā koi noi piha: ka ʻike ʻana i ka wai, ka paona kaumaha, a inā paha he mea noʻonoʻo ka pale o ka oxygen.

Hāʻawi ʻo Jushuo Packaging i nā ʻōnaehana kāʻei PP piha me ka pale ʻana i ka wai no nā noi koi. ʻO kā mākou mau laina hana 5 PP me 20,000 tons makahiki hiki ke hōʻoia i ka maikaʻi ma waena o nā kikoʻī āpau. Kākoʻo mākou i nā mea kūʻai aku ma o ke koho ʻana i nā mea e pili ana i nā koi noi, e komo pū ana me ka loiloi ʻike wai.

Inā makemake ʻoe i ke kōkua no ke koho ʻana i ka mea strapping kūpono no kāu noi ʻana i ka moisture-sensitive, e ʻoluʻolu e hoʻouna i leka uila i sales@jushuopackaging.com , a e hāʻawi kā mākou hui ʻoihana i ke kākoʻo hoʻokahi.
