Xav txog tej yam koj nyiam khoom noj txom ncauj ntawm nws lub ncov kawg: chips yog li crisp lawv crackle nrog txhua txhua tom, kas fes taum tso lawv cov roj tsw qab, txiv ntseej nrog lawv cov roj ntuj zoo kawg nkaus khaws cia. Tam sim no xav txog tib yam khoom noj txom ncauj tom qab peb lub lis piam hauv kev ntim khoom zoo: stale, soggy, flavorless.
NtawmYingFei Pob, peb pom qhov xwm txheej no tshwm sim txhua hnub. Khoom noj khoom haus ci ntsa iab, rhuav tshem los ntawm kev ntim khoom tsis txaus. Yog vim li cas peb thiaj li mus ntim zaub mov tsis yog khoom, tab sis raws li kev khaws cia science.
Cov ntsiab lus technical - OTR, WVTR, COF - tsis yog kev lag luam jargon xwb. Lawv yog cov riam phom zais cia hauv kev ua tsov rog tawm tsam zaub mov. Cia peb rhuav tshem lawv:
OTR (Oxygen kis tus nqi)
Xav txog cov pa oxygen ua yeeb ncuab pej xeem #1 rau feem ntau cov zaub mov. Nws ua rau:
Rancidity hauv cov roj thiab cov rog (uas "tawm" saj hauv txiv ntseej thiab chips)
Degradation ntawm cov xim thiab tsw
Kev loj hlob ntawm cov kab mob aerobic
Peb cov kev daws teeb meem: Peb tsim cov teeb meem nrog OTR kev ntsuas qis li 0.1 cc/m²/hnub - zoo tsim lub tshuab nqus tsev-zoo li ib puag ncig yam tsis muaj lub tshuab nqus tsev.
WVTR (Water Vapor Transmission Rate)
Moisture yog stealthy saboteur uas:
Ncua crispness los ntawm crackers thiab chips
Tsim clumping hauv hmoov
Txhawb kev loj hlob ntawm pwm
Peb cov kev daws teeb meem: Peb cov dej noo noo tuaj yeem ua tiav WVTR cov qhab nia qis dua 0.5 g / m² / hnub, ua kom koj cov khoom nkig hauv qhov chaw ntub dej.
COF (Coefficient of Friction)
Qhov kev ntsuas zoo li tsis pom tseeb no txiav txim siab:
Yuav ua li cas smoothly lub hnab khiav ntawm cov khoom ntim
Seb lub hnab ntim ua ke thaum thauj thiab khaws cia
Yooj yim npaum li cas cov neeg siv khoom tuaj yeem nkag mus rau cov khoom
Peb cov kev daws teeb meem: Peb zoo - kho COF kom ua tiav, ua kom koj lub ntim ua haujlwm tsis zoo los ntawm peb cov kab ntau lawm rau koj cov neeg siv khoom txhais tes.
Nov yog qhov peb sib piv cov ntaub ntawv rau hom zaub mov:
Rau Oily/Fatty Foods (Nuts, Chips, Coffee)
Peb pom zoo cov qauv nrog tshwj xeeb oxygen barriers xws li:
Metallized films uas thaiv 99.9% ntawm oxygen thiab lub teeb
EVOH khaubncaws sab nraud povtseg uas muab superior gas barrier txawm nyob rau hauv nyias gauges
Tshwj xeeb sealants uas tiv thaiv cov roj tsiv teb tsaws los ntawm seams
Rau cov khoom noj qhuav / crispy (Crackers, Cereals, ncuav qab zib)
Qhov tseem ceeb ntawm no yog kev tiv thaiv dej noo:
High-kab laminates nrog cov dej tshwj xeeb- cov txheej tiv thaiv
Precision sealing uas tsim cov dej noo- nruj ib puag ncig
Cov kaum sab xis ntawm qhov sawv ntsug-cov hnab ntim khoom uas cov dej noo feem ntau nkag mus
Rau cov khoom noj tshiab / khov
Cov no xav tau ib txoj hauv kev sib txawv:
Txhaum- cov ntaub ntawv tiv taus uas tiv taus qhov kub thiab txias
Anti-kev kho huab cua uas tswj kev pom
Consumer Convenience
Ib qho yooj yim- qhib cov yam ntxwv, zippers rov qab tau, thiab cov qhov rais ntshiab uas txhim kho cov neeg siv kev paub.
Brand Enhancement
