Hoe sneller het oplost, hoe beter. Hoe minder residu er overblijft na het oplossen, hoe beter. Hoe helderder het opgeloste water, hoe beter.<\/p>\n<p style=\"font-weight: 400;\">2) Verschijningskwaliteit:<\/p>\n<p style=\"font-weight: 400;\">Hoe gladder de wikkeling, hoe beter. Er mogen geen duidelijke oneffenheden en rimpels aan de buitenkant van de rol zitten. Hoe vlakker de twee uiteinden van de rolfilm, hoe beter, binnen \u00b12 mm. Het oppervlak van de folie mag geen gebreken vertonen zoals bellen, perforaties, slakinsluitsels en zwarte vlekken.<\/p>\n<p style=\"font-weight: 400;\">3) Mechanische sterkte:<\/p>\n<p style=\"font-weight: 400;\">De treksterkte moet hoger zijn dan 25Mpa. Te weinig trekkracht trekt gemakkelijk weg. De breukrek moet groter zijn dan 180%. Minder is niet zacht. De scheurweerstand in een rechte hoek moet ongeveer 80KN\/m zijn. Anders is het bros bij breuk.<\/p>\n<p style=\"font-weight: 400;\">4) Opslagtijd: De in water oplosbare film met stabiele kwaliteit kan meer dan 1-2 jaar bewaard worden (zonder vocht).<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-1042\" src=\"https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/1-13.png\" alt=\"\" width=\"655\" height=\"435\" srcset=\"https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/1-13.png 655w, https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/1-13-300x199.png 300w, https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/1-13-18x12.png 18w, https:\/\/joyforce-tech.com\/wp-content\/uploads\/2024\/02\/1-13-600x398.png 600w\" sizes=\"(max-width: 655px) 100vw, 655px\" \/><\/p>","protected":false},"excerpt":{"rendered":"<p>1) Water solubility: Cold water soluble film requires that water can be dissolved in water above 4 \u2103.
