• Yuav zam li cas

Polypropylene ib leeg- degrades nyob rau hauv tshav ntuj ncaj qha nyob rau hauv 6-9 lub hlis.

Adhesives ntsuas rau "siv sab hauv tsev nkaus xwb" – they lose bond strength in heat (>50℃/ 120℃F) los yog high humidity.

Unlaminated thermal hloov khoom (wax / resin)- smudges los ntawm dew los nag.

UX lus qhia rau cov neeg yuav khoom:Simulate kev laus sab nraum zoov. Tso cov ntawv sau rau sab qab teb -faus windowsill rau 4 lub lis piam lossis khiav "drip test" nrog lub vaj hose rau 24 teev. Tshawb xyuas ntug lifting thiab xim ploj.

Kev pom kev yuav khoom:Tsis txhob xav tias "daim ntawv tsis muaj dej" los ntawm tus neeg muag khoom noj ua haujlwm sab nraum zoov, lossis rov ua dua. Cov ntaub ntawv science txawv hauv paus.

Ua raws li 5 -kauj ruam kev kawm- txheej txheem mus yuav:

Txhais koj qhov xwm txheej phem tshaj -- Nws puas yog dej khov? Diesel nchuav? Txhua hnub condensation? Sau ib kab lus.

Thov cov ntaub ntawv coj mus kuaj- Tsis txhob cia siab rau cov ntaub ntawv ib leeg. Kuaj adhesion ntawm koj lub thawv tiag tiag lossis khoom nto.

Tshawb xyuas cov nplaum nplaum lub zog sab nrauv- Tsawg- cov khoom siv hluav taws xob (xws li polypropylene jugs) xav tau tshwj xeeb siab -tack adhesives.

Nug kom ceev cov txiaj ntsig kev laus- Cov khoom lag luam muaj koob npe muab Q-SUN (UV) lossis cov ntaub ntawv humidity chamber.

Txiav txim me me kev cai khiav ua ntej- Txheeb xyuas qhov zoo ntawm kev luam ntawv (barcode readability, smudge resistance) ua ntej yuav ntau.

Xaiv ibwaterproof daim ntawv lotxhais tau hais tias decoding qhov chaw tiag. Rau kev ntim khoom noj, ua qhov tseem ceeb ntawm qhov txias txias -kev ua haujlwm dej noo thiab kev ua raws li FDA. Rau cov khoom siv sab nraum zoov, saib xyuas qhov tseem ceeb ntawm UV stability, puas ntsoog, thiab chemical endurance.

Ib daim ntawv sau npe yuav tsis ua haujlwm rau ob qho tib si. Tab sis los ntawm kev nkag siab txog lub ntsej muag cov khoom lag luam (PP vs. PET), cov nplaum nplaum (lub freezer- qib vs. siab-tack), thiab topcoats (resin ribbon vs. overlaminate), koj tuaj yeem yuav nrog kev ntseeg siab- zam tev, smudging, thiab rov qab muaj kev pheej hmoo.

Yog tias koj tsis paub meej, hu rau peb lub chaw kuaj mob nrog koj cov qauv khoom. Peb yuav pom zoo kom muaj ntawv pov thawjwaterproof daim ntawv lorau koj qhov kub thiab txias, noo noo, thiab tswj profile.

1. Kuv puas tuaj yeem siv tib daim ntawv lo rau ntawm lub hnab ntim khoom noj khov thiab lub vaj sab nraum zoov?
Tsis yog. Cov hnab ntim khoom noj khov yuav tsum muaj daim ntawv lo polypropylene nrog lub freezer -qib acrylic nplaum uas tseem hloov tau ntawm -20℃. Lub vaj hose daim ntawv lo xav tau daim ntawv lo polyester (PET) nrog UV-resistant nplaum thiab overlaminate. Siv ib qho rau ob qho tib si yuav ua rau tsis ua hauj lwm nyob rau hauv ob qho tib si txias embrittlement los yog UV yellowing.

2. Tus nqi ntau tshaj yog dab tsi - daim ntawv lo dej tsis zoo rau cov tais zaub mov txias?
Dawb BOPP (biaxially oriented polypropylene) nrog rau cov nplaum acrylic ruaj khov thiab thermal hloov resin ribbon. Qhov kev sib xyaw ua ke no ua rau cov dej ntws tawm, luv luv -lub sijhawm sib cuag dej khov, thiab cov kab ntim puv tsis siv neeg tsis ua txhaum koj cov peev nyiaj.
