Jämförelse mellan två olika plastningsprinciper, Cross Pac kontra konventionell plastning
Baled silage has become one of the most important conservation methods in Sweden. Because
we take our grass as silage we get the quality and the good hygenic that we would like to
have. Silage has become a big buisiness also in the horse feeding where many of the breeders
have changed from the hay to the hay-silage. The difference between regular silage and haysilage
is that the hay silage is dryer (60-70%DM). The hay-silage has also put higher demands
on machinery and wrapping material since the grass gets sharper and harder to press together
real hard.
The main reason for the test was to compare two different systems for wrapping, the new
Cross Pac and conventional. The test also compared different stretching (70 and 120%) of the
film and different number of layers. The results is shown in the conclusions below. The bales
that was used in the test were dried to about 70% DM, and were taken from the same area on
the field, this because we would like to get as little difference as possible between the bales.
Conclution.
? There were no difference in use of wrapping material (kg/bale) between CrossPac and
conventional wrapping.
? It is better to have higher stretching (120%) and more layers when using the same
amount (kg) of film, compared to 70% stretching with less number of layers
? The stretching of the film is the major factor for the use of film (kg/bale).
? There are no difference in losses and mouldgrowth between 70% and 120% stretching
of the film, when using the samme amunt (Kg) of film.
? The bales wrapped with Cross Pac had less losses and were more airtight than bales
wrapped with conventional technique.
