BOPP Precoated Film vs. Lwm qhov: Qhov tshawb nrhiav

Yog li cas BOPP Precoated Film yog qhov tshuab uas neeg siv yuav xaum ua qhov tseem ceeb

Thaum cov neeg siv qhov tshuab rau kev txhais kom zoo pib sib tham cov lamination, BOPP precoated film yuav pib tuaj, tsis yog los ntawm kev cuam tshuam, tab sis vim qhov tshuab muaj cov leej twg uas sib koom tes zoo rau kev tsim kho nyob rau hauv qhov tseem ceeb ntawm kev tsim kho ntau dua. Biaxially oriented polypropylene muaj cov leej twg uas muaj qhov tswv yim ntawm cov ntaub ntawv, qhov tswv yim ntawm cov dej, thiab qhov muaj lub cev uas lwm cov tshuab tsis tuaj yeem sib tham rau qhov nqi uas sib koom tes. Koj yuav paub txog qhov sib tham ntawm no los ntawm lwm cov tshuab uas sib koom tes yuav pab koj nrhiav cov tshuab zoo dua.

Yam li cas lub tshuab lamination yuav sib txawv rau hauv cov ntawv sib txawv

Cov ntawv uas tau muaj adhesive layer los ntawm heat-activated thiab tau muab xyuam rau hauv qhov kev tsim ntawv, yog li cov neeg siv khoom tsim tsis xav tau siv lub system adhesive uas muaj dej. Qhov sib txawv no yog qhov tseem ceeb rau hauv cov khoom uas siv ntau dua. Lamination uas siv adhesive muaj dej xav tau ib qho chaw xyuam adhesive, kev daim dej thiab qhov siv dej kom haum, uas txhua yam no tau muab ntxiv rau qhov tseem ceeb thiab qhov chaw nyob. BOPP precoated film siv tau hauv qhov temperature ntawm nip uas tseem ceeb ntawm 80°C thiab 120°C, raws li qhov adhesive formulation, thiab lub tshuab tau muaj rau hauv qhov seconds uas muaj pressure. PET-based precoated films siv lub tshuab zoo li no, tab sis siv hauv qhov temperature siab dua rau hauv qhov melting point siab ntawm PET, uas yuav ua rau cov ntawv uas tsis tuaj yeem siv hluav tais tawm (heat-sensitive substrates) li cov ntawv uas tsis muaj coating thiab muaj qhov ntev tsawg tau muaj kev nyuaj.

Txiav txwm cov ntawv tseem ceeb uas muaj hauv qhov sib piv

Qhov chaw siv lub tshuab lamination muaj ntau yam ntawv sib txuas, thiab ma ntuag yam muaj qhov kev ua haujlwm ntawd. Qhov peb pim hauv no cov yam tshuab uas tau siv dua li ntau rau hauv kev siv hauv tsev siv thiab kev siv rau cov khoom.

BOPP cov qhov tshaj li ntawm kev sib piv tsis muaj ntau dua, tab sis qhov lus no yuav cuag thaum qhov siv nyob rau hauv qhov kev ua kom zoo dua. Qhov kev ua kom muaj qhov ntsuas ntau, qhov kev ua kom muaj qhov ntsuas loj, los yog qhov chaw uas muaj qhov cua sov thiab qhov cua ntxhav yuav pab cov neeg siv nyob rau hauv PET los yog nylon rau qhov kev tiv thaiv qhov tshuaj ntxiv.

Qhov BOPP Precoated Film tsis tuaj yeem siv rau qhov chaw uas muaj qhov tshaj li

Kev txheeb xyuas tseem ceeb yuav tsum paub tias qhov ntaub ntawv no tsis tuaj yeem siv rau qhov chaw uas muaj qhov cua sov ntau dua thiab tsis muaj qhov ntaub ntawv tiv thaiv ntxiv, vim tias qhov polypropylene yuav tshwm qhov ntsuas ntau thaum siv ntau dua. Nws kuj tsis tuaj yeem siv rau qhov chaw uas muaj qhov cua sov ntau dua 100°C, puas li qhov chaw uas siv rau qhov khoom siv rau qhov khoom siv uas yuav tsum siv rau hauv microwave-compatible trays.

Lub tshuab tshuab nyob rau hauv lub tebchaws China tom qab pom qhov no txawv tibyam thaum cov khoom siv los ntawm lub tsev tshuab tshuab tau txais los ntawm lub tsev tshuab tshuab thiab muaj qhov tsis zoo ntawm cov ntaub ntawv uas tsis tuaj yeem nyeeb rau hauv cov kab laus. Qhov kev saib xyuas tau txhawj mus rau qhov tsis sib xws ntawm cov ntaub ntawv uas tau muab txuas lawm thiab cov ntaub ntawv uas tau siv rau kev txuas cov khoom siv uas nyeeb. Muab cov ntaub ntawv uas muaj qhov nyeeb siab dua tau ua kom zoo, tab sis qhov no tau qhia tias qhov sib xws ntawm cov ntaub ntawv thiab cov ntaub ntawv uas nyeeb yuav tsum tau txhawj xyuas li cov ntaub ntawv uas tau muab txuas lawm.

Thaum PET Precoated Film yuav tau txais cov ntaub ntawv uas muaj qhov siab

Rau cov qhov chaw uas kev ua haujlwm ntawm lub rooj tsuag yog qhov tseem ceeb tshaj plaws, PET precoated film muaj ntau dua rau qhov ntau dua. Lub refractive index ntawm PET muaj qhov gloss yooj yim dua thiab muaj qhov shadow definition zoo dua rau cov foil embossed. Cov neeg design packaging tshiab uas tsim rau cov khoom siv rau cov neeg nyiam thiab cov lus qhia tshiab feeb tshaj plaws yuav tso PET rau daim ntawv ntawm qhov ntim ntawd rau qhov no. Qhov tswv yim ntawm qhov no yog qhov ceev ntawm kev ua haujlwm, uas yuav tsum paub tias cov nip rolls thiab heat drum ntawm laminator tuaj yeem txhawb tau qhov output zoo ib yam tsis muaj kev cuam tshuam ntawm qhov ceev.

Tus data ntawm kev test uas tau pub rau hauv Flexographic Technical Association, qhov surface gloss (tshais los ntawm ASTM D2457 nyob rau hauv 60 degrees) rau cov laminate PET muaj qhov tshwj xeeb ntawm 85 rau 95 GU thaum 70 rau 80 GU rau cov BOPP-based films zoo ib yam nyob rau hauv qhov kev ua haujlwm zoo ib yam.

Kho cov specification rau qhov ua haujlwm

Lub tswv yim ntawd yog tsis ntau lub tswv yim tseem ceeb rau txhua qhov kev ua haujlwm. BOPP precoated film tuaj yeem siv rau qhov ntau ntawm kev siv lamination rau cov khoom siv los ua haujlwm, vim tias qhov kev sib piv ntawm txoj cai thiab kev ua haujlwm yog zoo heev rau qhov ntau ntawm cov khoom siv thiab cov kev siv haujlwm. PET yog qhov uas tau txais kev xav txog thaum kev sib piv ntawm kev ua haujlwm thiab kev tswj hwm ntawm qhov cua sov yog tsis tuaj yeem txiav txim. Cov khoom siv tsis plastic yog nyob ntawm kev pib tshaj tawm rau kev siv hauv kev ua haujlwm uas muaj kev tswj hwm rau cov khoom siv, tab sis lawv puav tseeg nyob rau hauv qhov cost siab dua thiab xav tau kev suav nrog kev ua haujlwm ntau dua.

EKO muab cov khoom siv no txhua yam, los ntawm BOPP precoated tshwj xeeb mus rau cov khoom siv inkjet thiab cov khoom siv tsis plastic, thiab muaj kev sib xws thiab kev ua haujlwm zoo ib yam los ntawm kev ua haujlwm ntawm cov khoom siv no rau dua li 20 xyoo.
