Abstract

Pakiranje se danas većinom sastoji od polipropilena (PP). Plastika izrađena od PP je glavni zagađivač vode i tla, jer je potrebno puno vremena da se razgradi, osim ako se ne spali ili reciklira. Ovo je vrijeme kada se okrećemo prirodnim materijalima za pakiranje. Jedan takav materijal su nanoceluloza i mikroceluloza koje potječu iz biljaka. Celuloza je linearni biopolimer koji se prirodno nalazi u biljnim stanicama poput drveta, pamuka i lana. Vlakna se mehaničkim ili kemijskim preradom prevode u mikro / nanofibril celuloze (MFC / NFC) ili mikro / nanokristale celuloze (MCC / MCC). Primjena premaza provest će se na laboratorijskoj razini u obliku preliminarnih testova za uporabu u proizvodnji papira. Papiri premazani nanocelulozom i mikrocelulozom testirat će se na površinske karakteristike i mogućnost otiska kako bi se utvrdilo može li se natjecati s plastičnom ambalažom od polipropilena. Ovo će istraživanje omogućiti industriji ambalaže hrane kao i grafičkoj industriji da postanu zeleni u svom proizvodnom procesu.

Abstract (english)

Packaging nowadays consists mostly of polypropylene (PP). Plastic made from PP is the major water and soil pollutant, since it takes a lot of time to break down, unless it is burned or recycled. Nowadays we turn to natural packaging materials. Nanocellulose and microcellulose that originate from the plants are such natural and eco-friendly materials. Cellulose is a linear biopolymer naturally found in plant cells such as wood, cotton and linen. Its fibres are translated by mechanical or chemical processing into cellulose micro / nanofibrils (MFC / NFC) or cellulose micro / nanocrystals (MCC / NCC). The application of coating will be carried out at the laboratory level in the form of preliminary tests for use in the paper production. Also, papers coated with nanocellulose and microcellulose will be tested for surface characteristics and printability to see if they can compete with polypropylene plastic packaging. This research will allow for the food packaging industry as well as graphic industry to go green in their production process.
