Abstract

Valoviti karton je grafički proizvod čija kvaliteta uvelike ovisi o parametrima i njihovim utjecajima tokom proizvodnje. Parametri sirovine uvelike utječu na kvalitetu valovitog kartona. Tokom proizvodnje trebaju se promatrati ti svi paramteri kako vi dobili savršeni proizvod. Te sirovine - papir i ljepilo moraju biti usklađene sa paramterima koji su vlaga, temperatura, vrsta i gramatura papira. Uslijed loše kvalitete paramtera i sirovina, završni grafički proizvod valoviti karton se savija, te takav nije kvalitetan za upotrebu u daljnjoj njegovoj primjeni (transport, zaštita i slično). Savijanje valovitog kartona, tj koritavost veliki je problem u ambalažnoj industriji i veliki dio proizvodnje otpada na loš proizvod. Industriji je koritavost veliki problem, te ga pokušavaju iskustvom i proizvodnjom smanjiti, ali zbog obujma posla ne stiže se posvetiti pažnju na istraživanje. Ovo istraživanje bi uvelike pomoglo grafičkoj struci u ambalaži. Provedeno je nekoliko razgovora sa djelatnicima ambalažne industrije i njihovi komenatari su da im koritavost radi velike probleme kao što su povrat proizvoda ili preveliki postotak ide na otpad (škart). Praćenjem i mjerenjm paramtera sirovine pokušati će se utjecati na kvalitetu završnog proizvoda valovitog kartona. Cilj ovog istraživanja je pratiti paramtere i smanjiti ili pokušati potpuno ukloniti koritavost valovitog kartona.

Abstract in english:	Corrugated board is a graphical product whose quality largely depends on the parameters and their effects during production. The parameters of the raw material significantly affect the quality of corrugated cardboard. During production should be seen these parameters that you deliver perfect product. The raw material - paper and glue must comply with the parameters which are moisture, temperature, type and weight of paper. Due to the poor quality parameters and raw materials, final graphic product corrugated cardboard is folded, this is not such a good quality for use in further its application (transport, protection, etc.). Folding corrugated cardboard, ie warping a major problem in the packaging industry and a large part of production is a bad product. To the industry warping is big problem, and they are trying with experience and production reduce problem, but due to the volume of work does not come to devote attention to research. This study would greatly assist in the packaging printing industry. Conducted several interviews with employees of the packaging industry and their commentaries that they koritavost is causing trouble such as recall or too large a percentage goes to waste. The monitoring and measurement of parameters of raw material will try to influence the quality of the final product corrugated cardboard. The aim of this study is to monitor the parameters and try to reduce or completely remove warping of corrugated cardboard.
