Abstract

Valovita ljepenka izrađuje se od različitih vrsta papira koje su po svojoj strukturi higroskopne. Navedeno svojstvo važno je kod upotrebe valovite ljepenke kao ambalažnog materijala u transportu pa ga je potrebno provjeriti te osigurati klimatske uvjete kako ne bi došlo do mogućeg oštećenja ambalaže zbog prevelike ili preniske vlažnosti. Za ispitivanje se koristilo 5 vrsta valovite ljepenke koje su bile izložene 5 različitih nivoa vlažnosti 35%, 45%, sobna (55%), 65% i 75%. Po 10 klimatiziranih uzoraka se ispitivalo na FCT, ECT, BT, PT, gramaturi i debljini. Dobiveni su rezultati srednjih vrijednosti ispitivanih valovitih ljepenki, isti su međusobno uspoređivani i ponuđene su preporuke o najučinkovitijoj uporabi ispitivanih valovitih ljepenki izloženih varijabilitetu vlažnosti.

Abstract in english:	Corrugated cardboard is made from different types of paper that are structurally hygroscopic. Specified property is important when using corrugated cardboard as a packaging material in transit so it is necessary to check and ensure climatic conditions to avoid possible damage to the packaging, because of excessive or too low humidity. To test was used 5 types of corrugated cardboard that were exposed to five different levels of humidity 35%, 45%, room (55%), 65% and 75%. By 10 air-conditioned samples are examined in FCT, ECT, BT, PT, weights and thickness. The obtained results are the mean values of tested corrugated cardboard, they are compared and then offered suggestions on the most efficient use of tested corrugated cardboard exhibited variability of humidity.
