Yuav nyuaj txawm xav txog tias txawm nees nkaum tsib xyoos dhau los hauv khw muag khoom noj lossis khw muag khoom me me, tsis muaj lub khw muag khoom loj, lawv tseem tsis tau hnov txog zaj duab xis ntim khoom noj. Xav txog, ntim rau cov khoom noj khoom haus ntau yog ib lub hnab ntawv uas cov khw muag khoom noj khoom haus deftly twists nyob rau hauv pem hauv ntej ntawm koj. Tsev cheese hauv chav ua noj mis - hauv ib lub hnab zoo sib xws. Kefir thiab ryazhenka tsuas yog nyob rau hauv iav fwj, mis nyuj thiab qaub cream ib yam nkaus, los yog txawm rau bottling nyob rau hauv koj lub hub los yog tau. Muaj cov ntsiab lus sau rau cov thawv iav. Ib zaj dab neeg los ntawm kev ua yeeb yaj kiab kev tshawb fawb los yog kev txaus siab, kev tshawb fawb tsis tseeb! Nyob rau hauv kev nrhiav kev yooj yim ntawm lub neej bustling ntawm megacities, peb pib hnov qab lub saj ntawm tej yam ntuj tso khoom, tsis yog li txaus nyiam thiab alluring li nyob rau hauv kaj advertising pob khoom, tab sis yog li cua, thiab tseem ceeb tshaj, noj qab nyob zoo. Yog li ntawd, cia peb sim nkag siab tag nrho ntau yam ntawm cov khoom ntim khoom noj thiab lawv ua raws li kev nyiam huv thiab kev huv huv, vim. nyob ntiaj teb no, lawv tseem tsis tau muaj.

Cov kev xav tau yooj yim rauntim

Hnub no txhua yam tau ntim txhua qhov chaw. Tab sis txawm hais tias koj yuav cuam tshuam los yog txaus nyiam npaum li cas, tsis txhob hnov qab tias cov ntim khoom noj yuav tsum ua ntej ntawm tag nrho cov tiv thaiv lawv los ntawm cov kab mob, microbes thiab lwm yam teeb meem, thiab ib puag ncig los ntawm cov pa phem, thiab khaws cia kom muaj nuj nqis ntawm cov khoom. Thaum yuav khoom, tshwj xeeb tshaj yog cov khoom puas tsuaj, koj yuav tsum ua tib zoo xyuas qhov tseeb ntawm lub ntim, nws qhov zoo, ntau lawm thiab lub sijhawm ntim. Synthetic yas ntim rau cov khoom noj khoom haus yuav tsum muaj daim ntawv pov thawj huv ntawm kev ua raws li txhua yam kev tu cev thaum nws tsim khoom. Tsuas yog nws lees paub lub cev tsis muaj zog thiab lom neeg tsis zoo ntawm cov khoom no rau tib neeg kev noj qab haus huv. Cov khoom sib txawv muaj cov qauv sib txawv thiab cov kev cai rau kev khaws cia thiab kev thauj mus los, tab sis lawv nruj heev. Cov tub luam thiab cov chaw tsim khoom yuav tsum ua raws li lawv nruj me ntsis.

Kev faib khoom ntim khoom noj

Muaj ntau txoj hauv kev los faib cov ntim khoom. Qhov feem ntau - raws li cov khoom siv los ntawm nws yog ua. Cov feem ntau ancient nyob rau hauv no kev faib yog ntoo, iav thiab textile ntim. Cov no yog cov thoob, thawv, kaus poom, fwj, hnab thiab lwm yam. Nyob ib ncig ntawm lub xyoo pua xya, daim ntawv qhwv tau tsim nyob rau hauv lub teb chaws Yelemees. Los ntawm nruab nrab ntawm lub XIX caug xyoo, nws tau los ua parchment. Nyob rau tib lub sijhawm, cov duab los qhia thiab cov thawv ntawv tau tshwm sim hauv khw pastry. Nws yog lawv uas tau los ua thawj tus neeg nqa khoom ntawm kev tshaj tawm. Tin kaus poom tau pib siv rau hauv kev khaws cia ntawm ntau yam khoom ntawm qhov kawg ntawm lub xyoo pua kaum yim, qhov no yog qhov pib ntawm kev siv hlau ua ntim. Nees nkaumxyoo pua ushered nyob rau hauv lub era ntawm niaj hnub ntim, thaum polymer ntim rau zaub mov tshwm. Nws muab faib ua nruj, semi-rigid thiab mos nyob ntawm cov khoom ntawm cov khoom.

Txawm hais tias lub ntim khoom yog tsim los ntawm dab tsi, nws tuaj yeem ua lag luam, thaum cov khoom tau ntim los ntawm cov chaw tsim khoom, lossis kev lag luam, uas yog nqa tawm ntawm kev lag luam lag luam. Raws li lub voj voog ntawm kev siv, muaj cov ntim khoom pov tseg thiab rov siv tau. Los ntawm qhov ntau ntawm cov khoom nyob rau hauv lub pob - daim, ntau thiab portioned. Thiab los ntawm kev teem caij nws tau muab cais rau hauv kev sim, rau cov khoom tshiab, zoo tib yam thiab festive; muaj peev xwm loj lossis me me. Ntxiv nrog rau cov txheej txheem ntim khoom, lawv tsim cov ntim khoom qub lossis tus kheej rau cov khoom tshwj xeeb lossis cov neeg siv khoom tshwj xeeb.

Natural-based packaging feature

khob ntim khoom ua ntej ntawm kev nyab xeeb.

Nws ua haujlwm raws li lub ntim rau cov khoom ua kua thiab ua rau hauv daim ntawv ntawm lub raj mis, cov kaus poom, lub tog raj kheej ntawm ntau lub peev xwm. iav yog cov khoom siv tshuaj tiv thaiv uas tsis ua mob rau cov zaub mov, tsis ua rau nws saj, thiab tso cai rau koj pom cov ntsiab lus. Nws ntseeg tau tiv thaiv cov kab mob, muaj kuab paug, noo noo. Yooj yim huv. Yog li ntawd, tus me nyuam cov zaub mov nyob rau hauv daim ntawv ntawm purees thiab kua txiv yog ntim rau hauv lub khob hub. Thaum ntim cov qauv qhuav npaj rau cov menyuam mos, cov thawv ntawv yog siv rau feem ntau, thiab cov khoom ntim khoom zoo.

Qhov tsuas yog qhov tsis zoo ntawm iav yog brittleness, cardboard yog qhov ua tau ntawm deformation thiab tsis tshua muaj kev tiv thaiv rau ya raws yog tias tsis thauj lossis khaws cia. Los ntawm lub ntuj polymer - cellulose tau los ntawm paj rwb, ib puag ncig tus phooj ywg thiab tsis muaj teeb meem ntim cov ntaub ntawv yog tsim - translucent parchment, crispy sub-parchment, parchment ntawv ntxiv kho nrog glycerin, cellophane. Lawv siv ib leeg, thiab feem ntau ua ke nrog lwm cov ntaub ntawv, thaum ntim cov khoom muaj roj, txuj lom, tshuaj yej thiab lwm yam khoom noj.

Metal ntim

Cov thawv hlau ua los ntawm tinplate, galvanized vov tsev hlau, thiab aluminium alloys yog tus cwj pwm los ntawm cov neeg kho tshuab siab thiab kev nyab xeeb khoom noj. Txhawm rau tiv thaiv corrosion, nws sab hauv yog npog nrog cov khoom noj tsis zoo-qib enamels uas tsis hloov cov saj ntawm cov kaus poom. Aluminium ntawv ci tau siv dav, tshwj xeeb tshaj yog ua ke nrog cov ntawv txheej. Nws yog impervious rau microorganisms, oxygen, tshav ntuj, tsw.

Laminated ntawv yog zoo tagnrho rau ntim cov khoom siv mis nyuj.

Synthetic polymers thiab khoom noj khoom haus

Lub khw ntim khoom noj tau pib tsim sai heev vim yog siv ntau yam khoom siv hluavtaws. Synthetic-based polymeric ntim zaub mov muaj ntau haiv neeg, lub teeb, tsis rot. Ua ntej tshaj plaws, cov no yog polyolefins. Polyethylene, PE, ntau qhov sib txawv yog siv dav hauv kev cia khoomTam sim no cov khoom noj khov khov uas nrov nrog qhov muaj peev xwm rov ua kom sov vim nws cov Frost tsis kam, roj permeability, inertness rau dej thiab aggressive ib puag ncig.

Polypropylene tsis yog txias resistant. Qhov kom zoo dua ntawm PP yog nws tsis kam mus rau lub sij hawm raug kub siab, uas yog vim li cas nws yog siv nyob rau hauv lub tsim ntawm ntim rau sterilized khoom.

Polyethylene terephthalate yog mechanically ruaj khov ntawm qhov kub thiab txias. PET yog siv los tsim cov yeeb yaj kiab, lub raj mis yas thiab lub tshuab nqus tsev ntim khoom. Cov khoom no raug suav tias muaj kev nyab xeeb yog tias lawv tau sau npe raws li. Piv txwv li, cov cim RET ntshiab nyob hauv qab ntawm lub raj mis PET qhia tias nws tsis kam rau cov kua dej. Thiab PVC yog lub cim ntawm kev tiv thaiv tsuas yog dej, tom qab qhib thiab sib cuag nrog cov pa oxygen, lawv ua tsis tau zoo thiab muaj kev phom sij rau kev noj qab haus huv. Cov tais ntim cov cheese, cov khoom noj siv mis, cov khoom siv nqaij, cov thawv ntim khoom qab zib thiab lwm cov thawv yog ua los ntawm styrene polymers thiab copolymer. Cov khoom ua los ntawm polycarbonate yog hnav-resistant thiab khaws lawv cov khoom rau lub sijhawm ntev. PC ntim yog rov siv tau.

Cov khoom siv polyamide yog qhov ruaj khov, pob tshab, dej-, roj-, kub-thiab te-resistant, tsis tso cov tshuaj phem rau hauv cov zaub mov. PA yog kim heev, yog li nws feem ntau yog siv ua ke nrog lwm cov polymers. Polyurethane zoo sib xws hauv cov khoom rau PA, tab sis muaj tshuaj lom heev. PU daim ntawv lo rau ntawm lub ntim khoom noj yog qhov tsis tsim nyog. Txaus siab rau kev noj qab haus huv, siv cov thawv hluavtaws nkaus xwb rau nws lub hom phiaj.
