Tūtohi Hototahi Kiriata Lidding mō ngā Paepae CPET, APET, PET/PE me PP

Te Matrix Hototahi Kiriata Lidding mō ngā Paepae CPET, APET, PET/PE me PP

Ka tīpakohia te kiriata taupoki tika mā te taurite i tōna paparanga hiri-wera ki te rauemi e whakaaturia ana i runga i te flange o te paepae—kaua ko te rauemi anake kua whakaingoatia i runga i te whakatakotoranga o te paepae.

He mea tino nui tēnei rerekētanga ina rapu ana i te kiriata taupoki mō ngā tono paepae PET. Ko te tikanga he mata hiri PET kei roto i te paepae APET, ko te paepae PET/PE ia he PE kei te flange. Ahakoa kei roto i ngā paepae e rua te PET, he rerekē ngā hiri kiriata taupoki e hiahiatia ana mō rāua.

Kei te tūtohi e whai ake nei ngā wāhi tīmatanga whai hua mō te whiriwhiri kiriata me ngā whakamātautau raina.

* He awhe ārai ēnei pāmahana, ehara i te tautuhinga whakaputa kua whakamanahia. Tērā pea ka mahi ngā kiriata tīmatanga-iti me ngā kiriata whānui i waho o ēnei awhe. Me tīmata tonu me te pepa raraunga hangarau a te kaiwhakarato kiriata, ā, me manatoko te matapihi i runga i te mīhini tuturu.

† Ko te pāmahana ratonga e whakaahua ana i ngā āhuatanga rokiroki, whakamahana anō rānei. Kāore i te rite ki te pāmahana kauae-hiri. Me whai mana ngā oumu, ngā ngaruiti, ngā pouaka tio, ngā kereme whakautu katoa ki te pūnaha paepae-kiriata-kai katoa.

He aha te take e whakatau ai te mata o te pereti i te hototahitanga

He maha ngā paparanga mahi o tētahi kiriata taupoki:

• He paparanga PET, BOPET rānei o waho mō te kaha, te mārama, te pumau o ngā āhuatanga me te tānga

• He EVOH whiriwhiri, he paninga, he paparanga ārai rānei

• He piripiri whakapiri, he paparanga here rānei

• He paparanga hiri-wera o roto e pā tika ana ki te parirau o te paepae

• He kōwhiringa mō te ārai-kohu, te tihore, te whakapūhau rānei

Ko te paparanga hiri wera o roto rawa anake te mea e hono ana ki te paepae. Me hototahi tōna matū ki te pūmua, ki te paninga rānei e whakaaturia ana i runga i te flange.

Koia te take kāore e tika ana te kiriata e kiia ana ko te 'kiriata taupoki PET' mō ngā paepae katoa kei roto he PET. Ko te kawe o waho pea he PET, ko te hiri ia he PE, he PP, he paninga whānui rānei.

I mua i te tono, whakaū:

1. Te hanganga katoa o te paepae, ehara i te ingoa whānui o te rauemi anake

2. Ko tēhea paparanga e kitea ana i runga i te flange hiri

3. Ahakoa he paninga, he kiri hiri, he hanganga ihirangi hangarua rānei kei te flange

4. Ahakoa he ngāwari te tango, te tuku wera, te hiri rānei te katinga e hiahiatia ana

5. Te huringa rokiroki, tohatoha me te whakamahana anō o te kete katoa

He aha te kiriata pai rawa atu mō te paepae CPET?

Ko te kiriata mō ngā tono paepae CPET me whakamahi i tētahi kawe PET, BOPET rānei e pumau ana te rahi me te paninga hiri wera e hototahi ana ki te CPET. Mena ka uru te kete ki tētahi oumu tikanga me te taupoki e piri ana, me tika ia wāhanga mō te pāmahana me te wā oumu kua tohua.

Kei roto i taua whakaritenga te kiriata, te paninga hiri-wera, te piripiri ramine, ngā waituhi, te maimoatanga ārai-kohu, te flange paepae me ngā tohutohu kaihoko kua tāia.

Kōwhiria te whanonga kiri CPET mā te tono

• Māmā te tango i te taupoki i mua i te whakamahana. Me mau tonu te hiri i te wā e whakamatao ana, e tio ana rānei, engari me tuwhera ma i te wā e whakaritea ana.

• Te kiri tuku wera: Ka noho hiri tonu te kiriata i te wā e rongoa ana, ā, ka tukuna, ka pūhia rānei ngā hau i runga i te āhua whakahaere i te wā e wera ana te kai.

• Te whakamahana i muri i te tango hau: Ka tangohia, ka pokaia, ka whakatuwherahia rānei e te kaihoko tētahi hau kua hoahoatia i mua i te whakamahana i roto i te ngaruiti, i te oumu rānei.

• Hiri raka: Ka whakamahia he katinga tuturu ina hiahiatia he haumarutanga nui, ā, ka huakina te taupoki mā te tapahi, mā te haehae rānei.

Tērā pea he rerekē ngā hanganga mata o ngā paepae CPET, he kiri hiri PET koretake rānei. Nō reira, ka taea e ngā paepae e rua e hokona ana hei CPET te whakaputa i ngā kaha hiri rerekē me te kiriata kotahi.

Kaua e whakatau ko te kaha ki te tunu kai mai i te paparanga o waho o te PET.

Kāore e taea te tunu aunoa i te papa PET/PE whānui. Ahakoa ka taea e te kawe PET te tu atu ki ngā pāmahana teitei, tera pea he iti iho ngā rohenga o te hiri PE, te piripiri, te waituhi tā me te maimoatanga ārai-kohu.

Whakamahia anake te taumata kiriata kua whakamanahia mō:

• Ko te paepae CPET tuturu

• Te pāmahana oumu mōrahi

• Te roa o te whakamahana

• Te momo kai me te taumaha whakakī

• Mehemea kei te piri tonu te taupoki

• Ngā tohutohu e hiahiatia ana mō te whakapūhau, te tango rānei i te hau

Me pēhea te whiriwhiri i te kiriata taupoki mō ngā paepae APET me rPET

E whakamahia whānuitia ana te APET mō ngā kai matao, ngā hua rākau, ngā hua tunu taro, ngā huamata, ngā hua miraka me ngā pūmua hou. He tino mārama, engari kāore i te nuinga o te wā e whiriwhiria ana mō te whakamahana i roto i te oumu.

Mō tētahi flange APET noa, ko ngā kōwhiringa pai ko:

• BOPET pania ki te hiri wera

• Kiriata taupoki Mono-PET me te paninga hiri hototahi ki te PET

• He papa PET ārai-teitei me te hiri hototahi ki te PET

• Kiriata ngāwari-huia whānui kua whakamatautauria motuhake ki te APET

Me whakawhanake e te kiriata taupoki APET pai te kaha o te hiri mō te whakahaere me te tohatoha, me te kore e hiahiatia he wera nui e whakapohehe ana i te flange.

Ka taea e ngā ihirangi hangarua, ngā tae, ngā tāpiringa ārai-poraka me ngā tikanga hanga-tere te whakarerekē i te matapihi hiri. Nō reira, me tohu te tere rPET hei taumata tere tuturu, kaua e whakaarohia he rite tonu te whanonga ki te APET tauhou.

Mō ngā hua matao, whakaarohia te whakakotahi i te hototahitanga PET me:

• Mahi ārai-kohu makariri

• Te māramatanga teitei

• He ngāwari te tihore

• Ārai MAP

• Te pokanga taiaho, te pokanga ā-mīhini rānei

• Tā whakamuri

• Ātete pānga pāmahana iti

He aha i te nuinga o te wā ka hiahiatia he kiriata taupoki hiri-PE mō ngā paepae PET/PE?

He maha ngā paparanga o ngā paepae PET/PE. Ka whai wāhi te PET ki te pakari me te āhua, engari ka taea e te PE te whakarato i te mahi hiri me te ātete ki te makuku. Mena ka kitea te PE i runga i te flange, me hiri te taupoki ki te PE—ahakoa e hokohokohia ana te paepae hei paepae PET.

Ko ngā kōwhiringa noa ko:

• BOPET/PE mō ngā tono matao whānui

• PET/EVOH/PE mō ngā whakaritenga arai-hāora teitei ake

• He PET tānga kua pania ki te hiri PE ka taea te tihore

• PE-hototahi kiriata hipoki ao

Koinei tētahi o ngā tino take o ngā hapa hoko. Tērā pea kāore e piri pono te paninga hototahi ki te PET mō te APET noa ki te mata hiri PE. I tua atu, kaua e whakaarohia he kiriata hiri PE e hiri tika ana ki ngā flange CPET, APET rānei kāore anō kia pania.

Ina tono koe mō te kiriata taupoki mō te takai paepae PET, me kī tonu mēnā ko te paepae:

• Mono APET, rPET rānei

• CPET

• PET/PE

• PET/EVOH/PE

• PET me te kiri hiri motuhake

Ko tēhea kiriata taupoki e mahi tahi ana me ngā paepae PP?

Ko ngā paepae PP e hiahiatia ana he hiri hototahi ki te PP pērā i te CPP, he ranunga PP kua whakarerekētia, he paninga whānui motuhake rānei kua whakamanahia ki te PP.

Ko ngā hanganga noa ko:

• BOPET/CPP

• PET/PP

• PET/EVOH/PP

• Kiriata taupoki BOPP, kiriata taupoki PP rānei kua whakakotahihia

• Kiriata tihorea whānui e tika ana mō te PP

He whānuitia te whakamahinga o te PP mō ngā kai matao, ngā kai deli, ngā hua e taea te whakamahi i roto i te ngaruiti me ngā tono whakakī wera. Heoi, ko te pai o te whakamahi i roto i te ngaruiti ehara i te mea he pai te takai ki te whakahoki mai, ki te haumaru rānei ki roto i te oumu noa.

Me whai kiriata, hiri, piripiri me te pūnaha tā hei tu atu i te huringa pēhanga me te pāmahana katoa mō te kete whakahoki. Me aromatawai te kaha o te hiri i mua atu, i muri mai hoki i te tukatuka.

He Whakamārama mō te Tango Māmā, te Tukunga Wera me te Maukati i te Hiri

Ko te kupu 'peelable' e whakaahua ana i te wheako a te kaihoko, engari ka taea e ngā tikanga hiri rerekē te waihanga i taua wheako.

Ehara i te tikanga ngāwari te tango i te paparanga kore i whakamaheretia. Mēnā ka wehea te kiriata o waho mai i tana hiri, ka waiho pea te rauemi i runga i te paparanga, ka puta te waituhi, te piripiri rānei, ā, ka puta he wheako kaihoko koretake.

Kāore te pāmahana hiri i rite ki te pāmahana ōumu

Ahakoa te pāmahana hiri-kauae he 180°C, ka kitea te atanga hiri mō te wā poto noa iho, ā, kāore pea e eke ki te pāmahana kauae katoa. Mā te huringa oumu ka wera te kete katoa mō ētahi meneti.

He whakaritenga motuhake ēnei:

• Te pāmahana tīmatanga o te hiri: Ko te wāhi ka tīmata te hanga o tētahi hononga ka taea te ine.

• Matapihi whakahaere: Ko te huinga o te pāmahana, te wā noho me te pēhanga e whakaputa ana i ngā hiri e tika ana.

• Te wera o te hiri: Ko te kaha o te hiri hou ki te ātete i te whakatuwheratanga i mua i te whakamatao.

• Pāmahana ratonga: Ko te pāmahana ka pā ki te kai i te wā e whakakī ana, e penapena ana, e whakamahana ana, e tunu ana rānei.

• Huringa wera mōrahi: Ko te pāmahana me te roa e tika ana mō te kete katoa.

Ko te matotoru o te kiriata, te paninga taputapu, te tere o te raina, te pāmahana o te paepae me te whakawhiti wera mā te tukutuku, he mea whai pānga katoa ēnei ki te whanaungatanga i waenga i te pāmahana o te kauae me te pāmahana o te atanga.

Nā konei, kāore e pono te tārua i tētahi tautuhinga pāmahana mai i tētahi atu raina whakaputa—ahakoa he rite tonu te āhua o ngā paepae me ngā kiriata e whakamahia ana e ngā raina e rua.

Me pēhea te whakatū i tētahi matapihi hiri pono

Me whakatakoto te tautuhinga whakaputa i runga i tētahi whakamātautau raina whakahaeretia, kaua i runga i tētahi kete angitu kotahi.

1. Whakaū i te atanga rauemi

Tikina te hanganga o te paepae, ka tautuhia te pūmua, te paninga rānei e whakaatuhia ana i runga i te flange. Mena kāore i oti ngā tuhinga, tukuna ngā paepae tūturu ki te kaitahuri kiriata hei whakamātautau hototahi.

2. Whakamahia ngā tikanga tīmatanga kua tūtohutia e te kaiwhakarato

Rekoata:

• Te pāmahana o te kauae, o te pereti rānei

• Te wā noho

• Te pēhanga hiri

• Whānui o te hiri

• Te pāmahana o te taputapu me te paepae

• Tere o te raina

• Te aronga kiriata

• Te pāmahana whakakī hua

3. Whakamātauria ētahi huinga tawhā

Waihangahia ngā tautuhinga iti, waenga me te teitei huri noa i te awhe kua tūtohutia. Hurihia tētahi taurangi i ia wā, whakamahia rānei he hoahoa whakamātautau kua tuhia.

Ko te whāinga he kimi i tētahi wā mahi pumau—kaua ko te kaha tihore teitei rawa atu anake.

4. Arotakehia te kaha me te pono motuhake

He hononga te kaha o te hiri me te ātete turuturu engari kāore i te ōrite te ine. Ka taea tonu e te hiri kaha te pupuri i tētahi awaawa, engari kāore e hiahiatia he kaha whakatuwhera nui mō te hiri ā-hiri ma.

Ko ngā tikanga whai hua mō te tohu mātauranga ko:

• Te whakamātautau kaha-hiri i runga i te ASTM F88/F88M

• Aromatawai hiri wera taiwhanga i runga i te ASTM F2029

• Tirotiro hiri ā-kanohi

• He pai te uru o te tae mō ngā takai kore-pūpū

• Whakamātautau turuturu e ahu mai ana i te mirumiru, te korehau, te pēhanga rānei

• Whakamātautau pahū, whakamātautau ngokingoki rānei ina tika

• Te whakamātautau i te wāhi upoko o te MAP me te pupuri hau

• Te whakamātautau tohatoha, te wiri me te maturuturu

5. Whakamātauria anō i muri i te huringa wera tūturu

Arotakehia te kete i muri i ōna āhuatanga tuturu, tae atu ki:

• Whakakī wera

• Rokiroki matao

• Te tio me te rewa

• Te whakamahana anō i te ngaruiti

• Tunu kai i roto i te oumu tuku iho

• Te tukatuka whakautu

• Te roanga o te oranga e whakaarohia ana

Tērā pea ka rerekē te kaha o te kiri, te pakarukaru, te turuturu me te wehewehe i muri i te whakamātao.

Ārai, Ārai-Kohu me Ētahi Atu Kōwhiringa Mahi

Ko te hototahitanga o ngā paepae te whakaritenga tuatahi, engari ehara i te mea koia anake.

Ārai hāora me te makuku

Mō ngā kai MAP me ngā kai e pāngia ana e te wā e kore e taea te penapena, tohua ngā whakaritenga mō te tere tuku hāora me te tere tuku wai-kohu. Tuhia te pāmahana me te haumākū e inehia ai ia uara.

Ka taea e EVOH te whakarato i te arai hāora teitei, engari ko tōna mahi ka whakawhirinaki ki te hanganga me ngā āhuatanga taiao. Me whakamana te roa o te oranga o te kai mā te whakamahi i te kete katoa me te hua kai.

Mahi ārai-kohu

Mā te maimoatanga ārai-kohu ka āwhina i te makuku kua whakapūpūtia kia horapa ki roto i tētahi paparanga mārama, kaua ki te hanga i ngā pata e kitea ana. Whakamāramahia:

• Ārai-kohu wera, makariri rānei

• Te pāmahana kai me te whakakī

• Te pāmahana rokiroki

• Te roa o te whakamātautau

• Te taha kiriata e mau ana i te maimoatanga

• He hua tirohanga e whakaaetia ana

Kaua te ārai-kohu e whakaaetia kia whakaiti i te kaha o te hiri, kia poke rānei i te flange.

Te tā me te waehere

Mā te tānga whakamuri ka whakanohoia te mahi toi ki roto i te raima, hei tiaki i a ia mai i te pakaru. Me tika ngā waituhi me ngā piripiri mō te hanganga pā-kai me te huringa wera e hiahiatia ana.

I mua i te whakaputanga, whakaūtia te ahunga o te hurihuri, te tūnga o te tohu kanohi, te roa o te tukurua, ngā matapihi mārama me ngā wāhi waehere rā.

Te whakapūngao me te uruhanga

Tērā pea ka hiahiatia he pūhaumāota, he takirere, he hiri tuku wera rānei kua tohua ki te laser mō ngā kai ngaruiti. Tērā pea ka hiahiatia he poka nui, he poka moroiti rānei mō ngā hua hou, kaua ko te ārai mōrahi.

Ehara i te mea he pai ake te 'ārai teitei'. Ko te tere tika o te tuku hau e whakawhirinaki ana ki te manawa o te kai, te whāinga roa o te rokiroki me te āhuarangi o te takai.

Ngā Raru Kiriata Noa me ngā Mahi Whakatikatika

Ngā Mōhiotanga hei Whakarato ina Tono ana i tētahi Whakataunga Kiriata Lidding

Ka whakaitihia te wā tauira mā te whakatakotoranga katoa, ā, ka ārai i te taenga atu o te kiriata kore hototahi ki tētahi whakamātautau hanga.

Homai ngā mōhiohio e whai ake nei:

1. Kaihanga paepae me te waehere hua

2. Te hanganga katoa o te paepae me te paparanga whakapā flange tuturu

3. Te tuhi o te paepae, te whānui o te flange me te maha o ngā wāhanga

8. Te whānuitanga kaha-kiri whainga, mēnā e wātea ana

9. Momo kai, ngako, makuku, ranu me te tūponotanga o te poke o te flange

10. Te pāmahana whakakī me te tere o te raina

11. Ngā āhuatanga matao, tio, MAP, ngaruiti, oumu, retort rānei

12. Ko te OTR, WVTR, anti-kohu, te poka me te mahi tā e hiahiatia ana

13. Ngā ture e pā ana ki te kai me te mākete

14. Te rahinga ā-tau e tumanakohia ana me te whakaritenga whakamātautau-pukapuka

Ko tētahi hōputu tono whai hua ko:

Me whai kiriata taupoki [whānui me te matotoru] mātou mō [te waehere me te hanganga o te paepae]. Ko te paparanga flange e whakaatuhia ana ko [PET, PE, PP rānei]. Me whai [momo kiri], [ngā tikanga rokiroki], [tukanga whakamahana], [taumata ārai] me [ngā whakaritenga tā] te kete i runga i te hiri paepae [tauira mīhini].

Ngā Pātai Auau

Ko tēhea te kiriata taupoki pai rawa atu mō te paepae PET?

Tuatahi, whakatauhia mēnā he PET, he PE rānei te flange. Ko te APET noa me whai paninga hototahi ki te PET, ko ngā paepae PET/PE ia me te PE kei runga i te flange me whai hiri hototahi ki te PE.

Ka taea e te kiriata taupoki kotahi te hiri ki ngā paepae CPET, APET me PP?

Ae, ko ētahi hiri ā-ao kua hangaia mō ngā mata paepae maha. Heoi, me whakamana motuhake te hototahi, te kaha o te tihore me te ātete turuturu i runga i ia momo paepae me te raina whakaputa.

Ko tēhea kiriata e tika ana mō te paepae CPET?

Ko te tīmatanga noa he kiriata BOPET, PET rānei e taea te tunu ki te oumu, he paninga hiri wera e hototahi ana ki te CPET/PET. Mena ka mau tonu te taupoki i te wā e whakamahana ana, whakamahia he kiriata e tika ana mō te pāmahana, te wā me te tikanga whakaputa hau.

Ka taea e te kiriata taupoki PET/PE te hiri tika ki te CPET?

Kāore i te aunoa. Kāore pea he paparanga hiri PE e piri pono ki tētahi flange CPET kāore i pania, ki te kore he momo whānui, he momo kua whakarerekētia rānei kua whakamatautauria mō taua mata.

He aha te pāmahana e tika ana kia whakamahia hei hiri i ngā paepae CPET?

He maha ngā pūnaha CPET e arotakehia ana i te tīmatanga i roto i te awhe 180–220°C o te kauae, engari ko te tautuhinga tika e whakawhirinaki ana ki te paninga kiriata, te roa o te noho, te pēhanga, te taputapu me te mata o te paepae. Me matua whakaarohia ngā raraunga hangarau a te kaiwhakarato.

He haumaru ngā oumu kiriata taupoki CPET katoa?

Kāo. He rerekē ngā whakaritenga mō te hototahitanga o te paepae CPET me te āheinga ki te tunu i roto i te oumu. Me rite te hanganga kiriata katoa, te piripiri, te waituhi, te paninga me te takai hiri mō te huringa oumu e whakaarohia ana.

He aha te rerekētanga i waenga i te APET me te CPET?

He hanganga kore-āhua tō te APET e tino mārama ai, ā, e whakamahia whānuitia ana mō ngā takai matao. Ka whakakōkōhia te CPET kia nui ake ai te ātete ki te wera, ā, e whakamahia whānuitia ana mō ngā kai kua oti te tunu ki te oumu.

Ka taea tonu te pupuri i te hiri ngāwari-hutia kia mau tonu?

Āe. Mā te pūnaha ngāwari-huia kua hoahoatia tika ka taea te whakarato i te pumau o te takai me te ātete i te wā e tuwhera ana i raro i te mana whakahaere. Me whakamātautau motuhake te pumau o te hiri me te kaha whakatuwhera.

E whakamanahia ana e te kiriata ārai-teitei te roa o te ora e hiahiatia ana?

Kāo. Ko te roa o te oranga o te hua e whakawhirinaki ana ki te kiriata taupoki, te paepae, te wāhi hiri, te kai, te hau o te pane, ngā tikanga rokiroki me te pumau o te kete. Kāore e taea e ngā uara ārai anake te whakamana i te roa o te oranga o te hua.

Ka taea te hangarua anō i te kiriata taupoki mono-PET me te whakamahi i te paepae PET?

Tērā pea ka pai ake te hototahitanga o ngā rauemi mā te whakakotahitanga mono-PET, engari ko te āheinga hangarua kei te whakawhirinaki tonu ki ngā paninga, waituhi, piripiri, tapanga, toenga kai me te hanganga kohikohi me te hangarua i roto i te mākete ūnga.

Ture Kōwhiringa Whakamutunga

Mō te hiri pono o te paepae, whakamahia tēnei raupapa whakatau:

Tāutuhia te rauemi flange e kitea ana → taurite ki te paparanga hiri taupoki → whiriwhiria te whanonga tihore → tautuhia ngā whakaritenga ārai me te wera → whakatūria te matapihi hiri → manatokohia te kete katoa.

Kaua rawa e whakaaetia he kiriata nā te mea kei roto i te whakaahuatanga hua te CPET, APET, PET/PE, PP rānei. Tonoa ngā raraunga hangarau, whakamātauria te paepae tuturu, ā, whakahaerehia ngā whakamātautau tere-hanga i mua i te tuku i tētahi ota rahinga katoa.

Hei whiwhi i tētahi taunakitanga tika, tukuna mai ngā whakatakotoranga o tō paepae, ngā tauira tinana rānei me te tauira mīhini, te momo kai, te tukanga whakamahana me te whanonga tihore e hiahiatia ana.
