Muaj ntau hom kev sib khi thev naus laus zis rau kuv lub hnab ntim yas. Cov txheej txheem sib txawv yog tsim rau ntau hom khoom, cov khoom ntim khoom thiab cov kab ntau lawm. Cov hauv qab no yog ob peb hom kev sib khi thev naus laus zis rau cov hnab ntim khoom yas:
1. Thaum tshav kub kub sealing
Txoj kev sib khi feem ntau siv cov khoom cua sov kom muag thiab fuse cov ntaub ntawv yas.
Cov txheej txheem ntau:
Impulse Sealing: Lub sijhawm cua sov luv, haum rau cov yeeb yaj kiab thermoplastic xws li PE thiab PP.
Constant Heat Sealing: Cov cua kub tsis tu ncua, haum rau cov yeeb yaj kiab sib xyaw thiab cov hnab ntau - txheej.
Kub Bar Sealing: Nias lub hnab lub qhov ncauj tom qab cua sov nrog ib tug hlau clamp.
Cov ntaub ntawv siv tau: LDPE, HDPE, PP, PET, zaj duab xis sib xyaw, thiab lwm yam.
2. Ultrasonic Sealing
Tsim lub zog hluav taws xob los ntawm siab - zaus kev co txhuam kom fuse yas molecules.
Qhov zoo: ceev sealing, haum rau automation.
Tsis muaj pa luam yeeb thiab plua plav, ib puag ncig tus phooj ywg.
Sealing zoo, haum rau cov khoom noj thiab kev kho mob ntim khoom.
Cov ntaub ntawv siv tau: thermoplastics, non{0}}woven fabrics, laminated materials.
3. High Zaus Sealing (RF Sealing)
Siv siab- zaus hluav taws xob cua sov ua kom lub ncov qaumteb qabteb ntawm cov khoom yas molecules tsim kom sov thiab foob.
Qhov zoo: Haum rau cov khoom siv polarity siab xws li PVC thiab PU.
Lub zog sealing siab, haum rau cov hnab tuab lossis hnab nrog cov qauv tshwj xeeb.
4. Txias Sealing
Cov khoom ntim coated nrog txias sealing kua nplaum yog nias ua ke los ntawm lub siab kom ua tiav sealing yam tsis muaj cua sov.
Qhov zoo: Haum rau cov cua sov- cov khoom rhiab heev (xws li chocolate).
Ceev thiab zog-txuag.
Cov ntaub ntawv siv tau: Ntim zaj duab xis nrog txias sealing kua nplaum ua ntej-coated rau saum npoo.
5. Cua kub sealing
Qhov saum npoo ntawm cov khoom yog rhuab los ntawm cua kub tshuab, thiab ces kaw los ntawm cov menyuam nias.
Feem ntau siv rau hauv: lub hnab ua tshuab, peb- lub hnab ntim, zipper hnab thiab lwm lub hnab ua cov txheej txheem.
6. Kub Melt Adhesive Sealing
Siv cov nplaum nplaum kub kub los kaw lub hnab ntim khoom, haum rau lub ntim uas yuav tsum tau qhib thiab kaw dua.
Daim ntawv thov: re-Sealed self- hnab nplaum, nthuav lub hnab ntim.
7. Mechanical pressing + daim kab xev sealing
Tus kheej -cov nplaum nplaum siv rau cov hnab xa ntawv thiab cov hnab nthuav dav, uas tau muab khi los ntawm nias daim kab xev.
8. Common sealing structures:
Peb Sab Foob
Plaub Sab Foob
Center foob
Sawv ntsug-saum lub hnab hauv qab
Resealable Zipper
Tear Notch + Kub Foob
Slider Zipper Foob
Yog tias koj xav tau kev pom zoo rau lub tshuab sealing uas tsim nyog rau ib hom hnab ntim khoom (xws li lub hnab ntim khoom noj, lub hnab ntim lub freezer, hnab ziplock, thiab lwm yam), koj tuaj yeem muab lub hnab hom, cov khoom, thickness, lub hom phiaj, thiab lwm yam, thiab kuv tuaj yeem hais ntxiv txog txoj kev sib khi.
