(2) Ọnụego mgbochi mmiri mmiri: Uru dị mkpa nke mmiri na-egosi ≤0.5 g/(m²äh)

1. Ụkpụrụ amanyere iwu

Ọnụego mbufe ikuku mmiri (Wvr) nke yogọt cup okpomọkụ akara aluminum foil okpomọkụ-mechie mkpuchi ga-≤0.5 g /(m²äh), ihe na-egosi na-achịkwa yogọt mmiri ọnwụ na-erughị 0.3% kwa ọnwa. Na gburugburu iru mmiri dị elu (RH ≥85%), ọgwụ-ọkwa elu-ihe mgbochi aluminum foil (WVTR ≤0.1 g/(m²äh)) achọrọ iji gbochie mmetọ ebu nke condensation kpatara n'ime nkwakọ ngwaahịa. Nnwale data na aluminom foil gaskets maka iko yogọt na Jiangsu Province na-egosi na ngwaahịa ndị na-ekwenye ekwenye na-ejigide ụdị WVTR kwụsiri ike. 0.3-0.4 g /(m²äh), kwekọrọ na nsonaazụ njikwa usoro nke 8011-O aluminum foil si Mingtai Aluminom.

2. Mmekọrịta dị mma

Maka onye ọ bụla 0.1 g /(m²äh) mmụba na nnyefe mmiri, uru acid (mp) Mbelata nke yogọt na-abawanye site na 15%, na set yogọt bụ ngwa ngwa stratification. Site na njikwa ọkpụrụkpụ nke oke 0.04-0.09mm, Mingtai Aluminom na-ejigide WVTR mgbanwe nke aluminom foil substrates na ≤0.05 g/(m²äh).

(3) Ọnụego mgbochi ọkụ: Nchekwa Spectrum zuru oke nke ≥99.96%

1. Nka na ụzụ chọrọ

Ihe nkiri ihe mejupụtara nke aluminom ga-enwerịrị ihe mgbochi ọkụ nke ≥99.96% (nnyefe ọkụ ≤0.045%) n'ogo ogologo nke 200-760nm. N'ime nke a, ihe UV (200-380nm) ọnụego mgbochi ga-eru 100%; ma obughi otua, Ọnụ ọgụgụ nlanarị probiotic ga-ebelata site na 23% kwa izu, na vitamin D ọnwụ ọnụego ga-abawanye site 40%.

2. Nkwa ihe owuwu

N'ime PET/AL/PE·EVA nhazi ihe mejupụtara nke nwere akwa atọ, a 0.04mm yogọt cup okpomọkụ akara aluminum foil oyi akwa nwere ike kpamkpam gbochie anya ìhè; jikọtara ya na UV absorption Njirimara nke oyi akwa PET, ọ na-etolite nchebe abụọ. N'ihi nnyefe ọkụ nke ihe karịrị 85%, iko karama nkwakọ naanị na-akwado a shelf ndụ nke 3-5 ubochi, na-egosipụta isi uru nke foil aluminum maka mkpuchi ọkụ.

3. Isi ihe na-emetụta arụmọrụ mgbochi yana ụzọ nkwalite

(1) Njirimara mkpụrụ ihe nke aluminom

• Nhọrọ Alloy: 8011 aluminum alloy nwere 1.0-1.5% Si na 0.8-1.2% Fe, inye a 20% ihe mgbochi dị elu karịa aluminom dị ọcha. Ọ-steeti ya (keeji anya) ụdị nwere ezigbo ductility, na-egbochi mgbawa mgbe akpụchara, na-eme ka ọ bụrụ ihe kachasị mma maka mkpuchi yogọt. Ike tensile nke ime ụlọ ya ruru 100-120MPa, na elongation mgbe mgbawa bụ 8-10%, izute stamping na okpomọkụ-akara chọrọ nke akpaghị aka mmepụta ahịrị.

• Njikwa Ọkpụrụkpụ: Oke ọkpụrụkpụ nke ụlọ ọrụ ahụ bụ 0.04-0.09mm, ya na ụfọdụ ngwaahịa ahaziri agbatị ruo 0.018-0.2mm. Foil dị oke mkpa (<0.018mm) na-adịkarị mfe pinholes (≥3 pinholes kwa m² na-eme ka ọ ghara ịdị irè), mgbe nnukwu foil (>0.1mm) na-ebelata nkwụsịtụ ahịhịa na ndakọrịta ikpo ọkụ. Site na teknụzụ ntụgharị dị elu, Mingtai Aluminom na-achịkwa oke ndidi n'ime ± 0.002mm.

(2) Usoro ngwakọta na nhazi nhazi

1. Interlayer Synergy: Na nhazi PET/AL/PE·EVA, oyi akwa PET na-akwalite nguzogide ntupu (ike ikupu ≥3.5 N), oyi akwa PE·EVA na-eme ka ike mechie okpomọkụ (≥10 N/15mm), na aluminum foil oyi akwa na-elekwasị anya na ọrụ mgbochi. Adhesives ga-emezurịrị ihe ndị chọrọ nguzogide okpomọkụ; Adhesives dabeere na silicone nwere ike iguzogide sterilization 121 ℃ na-enweghị delamination.

2. Njikwa ntụpọ: Afụ na wrinkles n'oge nhazi ngwakọta ga-ezere, dịka ha nwere ike ime ka mmụba 10-15x na mberede na OTR mpaghara. Iji usoro nyocha AOI dị n'ịntanetị, Mingtai Aluminom rụpụtara nrụrụ ọkwa ọkwa 0.01mm, na-achịkwa ntụpọ ntụpọ nke ihe nkiri ndị mejupụtara ihe nkiri dị n'okpuru 0.02%.

(3) Ọnọdụ gburugburu ebe obibi na nchekwa

Igwe nju oyi dị ala (2-6℃) na-ebelata ọnụ ọgụgụ ikuku oxygen site na 30%; jikọtara ya na aluminom foil mgbochi, ọ na-agbatị ndụ shelf nke yogọt a kpalitere ka 28 ubochi. Maka nchekwa ụlọ-okpomọkụ (25℃), Ekwesịrị ibelata OTR ka ọ bụrụ ≤0.1cm³/(M² · 0h · 0.1MPA). Oke okpomọkụ na-emetụta yogọt cup okpomọkụ akara aluminum foil t arụmọrụ: oke okpomọkụ (>60℃) mee ka oyi akwa mkpuchi mkpuchi dị nro, mgbe obere okpomọkụ (<0℃) mee gaskets kewaa—ha abụọ nwere ike ibute ọdịda akara.

4. Ụkpụrụ ụlọ ọrụ na sistemu njikwa ogo

1. Ụkpụrụ Ọkọlọtọ Kacha ọhụrụ

2. Sistemụ njikwa ogo zuru oke

• • Nnwale mkpụrụ osisi: Nnwale ihicha mmiri ga-erurịrị ọkwa A (ọ dịghị ihe nkiri mmiri na-aga n'ihu na-agbaji) iji hụ na ịdị ọcha dị n'elu;

• • Ịme Nnwale: Stamping izi ezi ≤±0.2mm, ọ dịghị burrs na nsọtụ, ike bee ≥1.5 N/mm;

• • Nlele arụmọrụ: A na-anwale OTR site na usoro ihe mmetụta coulometric (Gb / t 1038.2-2022); A na-anwale WVTR n'okpuru okpomọkụ mgbe niile (38℃) na iru mmiri (90% 'Ny) nke 72 keolechi;

• • Njikwa gburugburu ebe obibi: A ghaghị ime mmepụta na klaasị 10,000 Ọdịmma dị ọcha, yana ngụkọta microbial ≤10 CFU/cm².

5. Ụdị Ọdịnihu: Ịhazi ihe mgbochi dị elu yana ịdịgide

1. Ihe ọhụrụ: Mmepe nke 0.009mm ultra-thin aluminum foil film composite composite, iji teknụzụ mkpuchi nano-SiO₂ iji nọgide na-enwe ihe mgbochi mgbe ị na-ebelata ojiji aluminom site na 30%. Mgbanwe ngwakọta nke 8011 alloy na Mg ọcha na-abawanye nguzogide aluminom foil okpomọkụ ruo 150 ℃, na-eme mgbanwe na ọnọdụ okpomọkụ ọkụ microwave，Yogurt-cup-okpomọkụ-akara-aluminom-foilt.

2. Nkwalite ihe owuwu: Nkwenye nke ihe owuwu ala anọ nke Al/PA/EVOH/PE na-ebelata OTR ka 0.01 cm³ /(M² · 0h · 0.1MPA), adabara yogọt na-enweghị nchekwa na ndụ ogologo ndụ. Mfe nke mfe ndọka akara imewe njikwa oghere ike na 5-8 N, imeziwanye ahụmịhe ndị ahịa.

3. Eco-Transformation: Ọganihu na teknụzụ nkewa nke aluminom-plastic—Mingtai Aluminom mezuru 95% Ọnụ ego mgbake aluminom site na ihe nkiri mejupụtara site na nkewa pyrolysis-electrostatic dị ala.. Ngwa nke ikpo ọkụ PE·EVA na-emebi emebi na-ebelata mmetụta gburugburu ebe obibi.
