Bl\u00e4ck som lossnar vid tryck p\u00e5 f\u00f6rpackningsp\u00e5sar<\/h1>\n

Bl\u00e4ckvidh\u00e4ftning \u00e4r en vanlig utmaning vid tryck p\u00e5 plastfilm och f\u00f6rpackningsp\u00e5sar. Ett enkelt tejptest kan visa om bl\u00e4cket sitter tillr\u00e4ckligt h\u00e5rt eller om det lossnar fr\u00e5n ytan.<\/p>\n

\"Specialanpassad
F\u00f6rpackningsp\u00e5sar beh\u00f6ver r\u00e4tt material, ytbehandling, bl\u00e4ck och efterbehandling f\u00f6r att trycket ska h\u00e5lla.<\/figcaption><\/figure>\n

Otillr\u00e4cklig UV-h\u00e4rdning<\/h2>\n

UV-bl\u00e4ck kan se torrt ut p\u00e5 ytan utan att vara helt h\u00e4rdat inuti. D\u00e5 blir vidh\u00e4ftningen svag och bl\u00e4cket kan lossna vid tejptest, friktion eller efterf\u00f6ljande hantering.<\/p>\n

L\u00e5g ytsp\u00e4nning p\u00e5 film<\/h2>\n

PE- och PP-filmer beh\u00f6ver ofta kontrolleras med dynpenna eller dynl\u00f6sning. Om ytsp\u00e4nningen \u00e4r f\u00f6r l\u00e5g beh\u00f6ver filmen corona- eller coatingbehandlas f\u00f6r att bl\u00e4cket ska f\u00e4sta b\u00e4ttre.<\/p>\n

Fel bl\u00e4ck f\u00f6r materialet<\/h2>\n

PET, BOPP och andra filmer kan ha olika coatings fr\u00e5n leverant\u00f6ren. Samma bl\u00e4ck fungerar inte alltid p\u00e5 alla ytor, s\u00e5 film, coating och bl\u00e4cksystem b\u00f6r testas tillsammans f\u00f6re produktion.<\/p>\n

Praktiska kontroller<\/h2>\n

Ett tumtryckstest kan visa om UV-h\u00e4rdningen \u00e4r tillr\u00e4cklig. UV-lampor beh\u00f6ver underh\u00e5llas, bl\u00e4ck ska lagras m\u00f6rkt och svalt, och film b\u00f6r helst anv\u00e4ndas medan ytbehandlingen fortfarande \u00e4r aktiv.<\/p>\n

Olika filmtyper<\/h2>\n

PE kr\u00e4ver ofta corona. BOPP har bra klarhet men kan vara k\u00e4nsligt i v\u00e4rmef\u00f6rsegling. PET har h\u00f6g glans och v\u00e4rmet\u00e5lighet. PVC, nylon, glassine och coated films kr\u00e4ver egna inst\u00e4llningar f\u00f6r torkning, sp\u00e4nning och tryck.<\/p>\n

Bl\u00e4cklossning l\u00f6ses genom att kontrollera h\u00e4rdning, ytsp\u00e4nning, bl\u00e4ckval och materialhantering. N\u00e4r testning och produktion h\u00e4nger ihop blir p\u00e5strycket mer stabilt.<\/p>\n","protected":false},"excerpt":{"rendered":"
