Du kan ikke se det, lugte det eller stoppe det \u2013 men din emballage m\u00e6rker det. Fra fugtig bund til kr\u00f8llede prints kan fugt \u00f8del\u00e6gge en god papirpose, f\u00f8r den overhovedet rammer hylden.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Fugtighed p\u00e5virker papirposer ved at sv\u00e6kke fiberstyrken, for\u00e5rsage vridning, bl\u00f8dg\u00f8rende lim og beskadige printede finish. Uden de rigtige materialer, design og opbevaring kan papirposer hurtigt miste holdbarheden i milj\u00f8er med h\u00f8j fugtighed.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tro mig \u2013 jeg har k\u00e6mpet mod fugt i over 15 \u00e5r i emballagespillet. Her er, hvad jeg har l\u00e6rt, og hvordan vi hj\u00e6lper kunder med at sl\u00e5 varmen (og fugten).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hvorfor papirposer er f\u00f8lsomme over for fugt<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Papir er lavet af tr\u00e6masse - organisk, fibr\u00f8st og absorberende. Det er dybest set en svamp i forkl\u00e6dning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">N\u00e5r den relative luftfugtighed (RH) stiger over 60%, begynder papiret at absorbere fugt fra luften. Dette p\u00e5virker:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Styrke<\/strong> \u2013 v\u00e5de fibre mister sp\u00e6ndingen<\/li>\n\n\n\n<li><strong>Form<\/strong> \u2013 papir kr\u00f8ller eller h\u00e6nger<\/li>\n\n\n\n<li><strong>V\u00e6gt<\/strong> \u2013 tilf\u00f8jet fugt \u00f8ger forsendelsesomkostningerne<\/li>\n\n\n\n<li><strong>Bl\u00e6k og laminering<\/strong> \u2013 kan udtv\u00e6re, skr\u00e6lle eller boble<\/li>\n\n\n\n<li><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Det er derfor, is\u00e6r for kunder i tropiske eller kystn\u00e6re omr\u00e5der, vi altid vurderer det lokale klima, f\u00f8r vi anbefaler papirtyper.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hvordan forskellige papirtyper reagerer p\u00e5 fugt<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ikke alt papir er skabt lige. Nogle papirer h\u00e5ndterer fugt som en professionel. Andre? Ikke s\u00e5 meget.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Her er, hvordan almindelige papirtyper stables:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Kraft papir<\/strong>: H\u00f8j t\u00e6thed, st\u00e6rke fibre, bedre modstand<\/li>\n\n\n\n<li><strong>Genbrugspapir<\/strong>: Bl\u00f8dere fibre, mere por\u00f8se, absorberer let fugt<\/li>\n\n\n\n<li><strong>Coated Papir<\/strong>: Kan modst\u00e5 vand, men bel\u00e6gningen kan boble eller revne i fugt<\/li>\n\n\n\n<li><strong>Lamineret papir<\/strong>: Modst\u00e5r bedre fugt, men kan delaminere, hvis den limes d\u00e5rligt<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Hos GreenWing anbefaler vi normalt virgin kraftpapir til kunder, der har brug for styrke og fugtbestandighed. Til f\u00f8devareemballage kan vi tilf\u00f8je et fugtbestandigt barrierelag \u2013 men aldrig p\u00e5 bekostning af komposterbarhed.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/greenwingpackaging.com\/wp-content\/uploads\/2025\/04\/Comparison-chart-of-kraft-vs-recycled-paper-in-humid-environments.jpg\" alt=\"\" class=\"wp-image-4314\" srcset=\"https:\/\/greenwingpackaging.com\/wp-content\/uploads\/2025\/04\/Comparison-chart-of-kraft-vs-recycled-paper-in-humid-environments.jpg 800w, https:\/\/greenwingpackaging.com\/wp-content\/uploads\/2025\/04\/Comparison-chart-of-kraft-vs-recycled-paper-in-humid-environments-300x225.jpg 300w, https:\/\/greenwingpackaging.com\/wp-content\/uploads\/2025\/04\/Comparison-chart-of-kraft-vs-recycled-paper-in-humid-environments-768x576.jpg 768w, https:\/\/greenwingpackaging.com\/wp-content\/uploads\/2025\/04\/Comparison-chart-of-kraft-vs-recycled-paper-in-humid-environments-16x12.jpg 16w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Limfaktoren: Holder det hele sammen (eller ej)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">De fleste k\u00f8bere t\u00e6nker ikke p\u00e5 lim. Men n\u00e5r det kommer til luftfugtighed? Lim er den tavse helt - eller det f\u00f8rste fejlpunkt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">H\u00f8j luftfugtighed kan:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Bl\u00f8dg\u00f8r lim<\/strong> over tid<\/li>\n\n\n\n<li><strong>Bryd forseglingen<\/strong> p\u00e5 h\u00e5ndtag eller sidekiler<\/li>\n\n\n\n<li><strong>Lad poserne v\u00e6re ubrugelige<\/strong> under forsendelse eller opbevaring<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Det er derfor, vi har udviklet vores egne limformler, testet ved op til 90% luftfugtighed.

Selv den bedste taske kan blive slap, hvis den opbevares forkert.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Her er, hvad jeg altid fort\u00e6ller vores partnere:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Opbevar poser forseglet i original emballage<\/strong> indtil brug<\/li>\n\n\n\n<li><strong>Undg\u00e5 direkte gulvkontakt<\/strong>-Pallet\u00e9r altid<\/li>\n\n\n\n<li><strong>Brug t\u00f8rremidler<\/strong> i skibscontainere i monsuns\u00e6sonerne<\/li>\n\n\n\n<li><strong>V\u00e6lg varehuse med RH-styring<\/strong> (is\u00e6r under 60%)<\/li>\n\n\n\n<li><strong>Roter lager hurtigt<\/strong> for at undg\u00e5 langvarig eksponering<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Vores lager i Kina er RH-kontrolleret, og vores eksportemballage bruger fugtbarrierefilm.
