Impact of the parameters of round and square haylage bales on the consumption of the sealing film for individual and in-line wrapping

In the Baltic States and Poland haylage processing in a baled form with subsequent sealing in a flexible film has been intensively applied for about 15 years, and now it occupies an important place among the forage processing methods. A drawback of this technology is the high cost of the film. There are factors investigated having impact on the cost of the film used for sealing individual round and square (rectangular) bales separately and in a long line. Comparative estimation has been made of the design values and the experimental data. For both variants, the size of the bales being equal, lesser consumption (approximately by 8%) of the film will be when the bales are sealed (wrapped). In contrast to individual wrapping of each bale, in-line wrapping of bales reduces the consumption of the film by two times.
