Cell Instruments, en innovat\u00f8r inden for l\u00f8sninger til materialetestning, annoncerer med stolthed sit engagement i fremragende hot tack-testning med vedtagelsen af ASTM F1921-standarderne. Dette markerer et vigtigt skridt i retning af at sikre emballagens p\u00e5lidelighed og integritet, is\u00e6r i hurtige produktionslinjer.<\/p>\n\n\n\n
Forst\u00e5else af ASTM F1921 Hot Tack-test:<\/strong><\/h2>\n\n\n\n
ASTM F1921-standarden fokuserer p\u00e5 at evaluere styrken af varmeforseglinger, der dannes mellem termoplastiske overflader p\u00e5 fleksible baner. Denne evaluering finder sted umiddelbart efter, at forseglingen er skabt, og understreger dens betydning, f\u00f8r den er k\u00f8let ned til stuetemperatur.<\/p>\n\n\n\n
Betydning i vertikal form-fyld-forsegling (VFFS) emballage:<\/strong><\/h2>\n\n\n\n<\/figure>\n\n\n\n
Hot tack-egenskaben bliver vigtig i VFFS-emballageprocesser (vertical form-fill-seal), hvor der er minimal k\u00f8letid til r\u00e5dighed. I VFFS-emballage l\u00e6gges produkterne hurtigt ned i posen, lige efter at forseglingsst\u00e6ngerne er \u00e5bnet. Den varme forseglings evne til at modst\u00e5 betydelige belastninger bliver afg\u00f8rende for at sikre dens styrke og sikkerhed. Dette er afg\u00f8rende for at forhindre potentielt produktspild eller pakkesvigt. Derfor er vurdering og optimering af hot tack-egenskaberne et afg\u00f8rende skridt for at opretholde emballagens p\u00e5lidelighed og integritet i h\u00f8jhastighedsproduktionslinjer.<\/p>\n\n\n\n
ASTM F1921 Hot Tack-testprocessen:<\/strong><\/h2>\n\n\n\n<\/figure>\n\n\n\n
Forsegling af pr\u00f8ver:<\/strong><\/h2>\n\n\n\n
En pr\u00f8vestrimmel forsegles ved at l\u00e6gge pres p\u00e5 med to flade, opvarmede k\u00e6ber under specifikke forhold med hensyn til temperatur, kontakttid og tryk.<\/p>\n\n\n\n
Tilbagetr\u00e6kning af pr\u00f8ve:<\/strong><\/h2>\n\n\n\n
N\u00e5r forseglingsenhedens k\u00e6ber \u00e5bner, tr\u00e6kkes den forseglede strimmel automatisk ud mellem k\u00e6berne, hvilket sker efter en defineret forsinkelsestid, som kan justeres og endda indstilles til nul. Tilbagetr\u00e6kningen sker ved at tr\u00e6kke grebene tilbage.<\/p>\n\n\n\n<\/figure>\n\n\n\n
Kraftm\u00e5ling:<\/strong><\/h2>\n\n\n\n
N\u00e5r grebene bev\u00e6ger sig fra hinanden med en forudbestemt hastighed, bliver den forseglede pr\u00f8ve forl\u00e6nget, indtil den til sidst brister. Under hele denne forl\u00e6ngelsesproces m\u00e5ler hot tack-testeren den kraft, der kr\u00e6ves for at opretholde forseglingen, indtil den n\u00e5r sit brudpunkt.<\/p>\n\n\n\n
