Abstract
Osnovna uloga ambalaže je zaštita jaja tijekom rukovanja, skladištenja i transporta. Novi trendovi i globalizacija tržišta zahtijevaju distribuciju hrane na velike udaljenosti, što na ambalažu stavlja sve vede zahtjeve u cilju zaštite zapakirane robe. Osnovne karakteristike dobrih ambalažnih materijala su mogudnost njihove masovne proizvodnje, efikasnost samog materijala, pogodnost njegove strukture i oblika, praktičnost upotrebe i utjecaj tog materijala na okoliš. Fizička zaštitna uloga pakiranja važna je kod proizvoda osjetljivih na udarce i vibracije kao što su jaja. Pri tome značajnu ulogu ima i sam materijal od kojeg su kutije izrađene. Konstrukcija kutija omogudava da se svako jaje postavi u za to predviđeno mjesto pri čemu je spriječen kontakt s drugim jajima u pakiranju. Materijal izrade i konstrukcija kutija štite jaja od neželjenih posljedica koje se javljaju tijekom prijevoza i skladištenja preuzimanjem sila umanjujudi njihovo djelovanje na ljusku jaja. Istraživanje je provedeno na 3 najzastupljenija tipa kutija za jaja koja se koriste na području Republike Hrvatske. Kutije su podvrgnute djelovanjem sila u smjerovima osi z. Sila potrebna za lom jaja ovisi o konstrukciji i materijalu izrade kutije. Najbolje rezultate pokazale su kartonske kutije kod kojih je za lom jaja potrebno primijeniti najveću silu.
Abstract (english)
The basic role of packaging is the protection of eggs during handling, storage and transport. New trends and globalization of the market require food distribution over long distances, which place on the packaging ever increasing demands. Conditions necessary to produce appropriate packaging are possibility for mass production, reasonable and efficient packaging material, suitable structure and form, convenience, and consideration of disposal. The physical protective role of packaging is important for shock and vibration sensitive products such as eggs. The boxes may be made from materials having different strengths and different wall thicknesses in order to control the deformation of the boxes. Box shapes have a dimpled form in which each dimple accommodates an individual egg and isolates that egg from eggs in adjacent dimples. This structure helps protect eggs against stresses exerted during transportation and storage by absorbing a lot of shock and limiting the incidents of fracture to the fragile egg shells. Boxes were compressed along their z-axis effectively indicated the cartons relative protective abilities. The force needed to break the eggs depends on the boxes design and material. Cardboard boxes showed best results according to maximum forces needed to break eggs.
