Abstract

Smatra se da je papir prvi puta proizveden u Kini u prvom stoljeću pr.n.e., a danas mu je
u svijetu upotreba široko rasprostranjena. Bez obzira na vrijeme digitalizacije u kojemu
živimo, papir je materijal koji nam je prijeko potreban za tiskanje, pisanje, izradu
ambalaže i slično. Osnovni materijali od kojih se dobiva papir su vlakna, kod kojih glavnu
ulogu nosi celuloza, te razni dodaci. Proizvodnja papira odvija se na papir – stroju. Taj
proces se strogo nadgleda kako bi se unaprijed predvidjele poteškoće i tako postigla
željena kvaliteta. Zbog povećane potrošnje sirovina za izradu papira, recikliranje papira
postaje sve važnija praksa u kontekstu očuvanja prirode i okoliša, uštede na financijama
i energiji. Cijeli postupak recikliranja papira sustavan je i organiziran te mu se prilazi vrlo
ozbiljno, putem nastojeći poboljšavati tehnološke procese izrade kako bi se ostvarili
najbolji rezultati. U radu su provedena ispitivanja općih, mehaničkih, optičkih i
površinskih svojstava tržišno dostupnih recikliranih papira viših gramatura. Putem
navedenih ispitivanja će se istražiti njihova pogodnost za tisak i ambalažu, te utvrditi
uporabna vrijednost s obzirom da se mogu reciklirati i do nekoliko puta.

Abstract (english)

It is believed that paper was first produced in China in the 1st century BCE, and today its
use is widespread around the world. Despite the digital age we live in, paper is a material
that is still essential for printing, writing, packaging, and more. The basic materials used
in paper production are fibers, with cellulose playing a major role, along with various
additives. Paper production takes place on a paper machine. This process is closely
monitored to anticipate difficulties in advance and achieve the desired quality. Due to
increased consumption of raw materials for paper production, paper recycling has become
an increasingly important practice in terms of nature and environmental conservation,
financial savings, and energy efficiency. The entire paper recycling process is systematic
and organized, and it is approached very seriously in order to improve the technological
processes involved and achieve the best results. The study conducted tests on the general,
mechanical, optical, and surface properties of commercially available recycled papers.
Through these tests, their suitability for printing and packaging will be investigated, and
their practical value will be determined considering that they can be recycled multiple
times.
