INFLUENCE OF TRANSPARENCY OF WRAPPING STRETCH FOIL ON COLOUR OF SMALL SLAVONIAN OAK WOOD (Quercus robur L.) SAMPLES DURING SHORT TERM WRAPPING AND EXPOSURE TO ULTRAVIOLET RADIATION

During some research wood often must be transported or temporarily stored and protected, while at the same time it is necessary to prevent the influence of solar radiation and water loss. For this purpose, most common protection used is transparent wrapping stretch foil. However, black wrapping stretch foil can also be found and bought on market in recent years. This black wrapping foil is opaque and at first glance it seems that it probably could be better for wrapping wood samples in it for protection. In this research oak wood (Quercus robur L.) small samples were wrapped in transparent and opaque wrapping stretch foil and exposed to various influences in the form of artificial UV radiation and Solar radiation. Thereafter, it has been determined whether there has been a change in colour.
