8.2 Plastic film requirements
Besides well shaped dense bales, a good silage quality also depends on the use of
top quality plastic film. Low standard film material will not produce good silage
regardless of how well the machine wraps the bale. The plastic film should be used
and stored according to the instructions of the film manufacturer.
It is recommended that a minimum of four (4) layers of film be applied to the
bale. If the material being wrapped is of a hard or stemmy nature it may be
necessary to apply six (6) or eight (8) layers to ensure a good airtight package.
Note: The operator needs to ensure that the bale is correctly wrapped.
It is good practice to check the bales regularly after being wrapped for correct
wrapping and for torn, split or perforated plastic film.
To determine the number of Wrapping Ring Rotations required to cover a bale
carry out the following procedure:
1. Using manual operation, from the control box, manually count the number of
‘Wrapping Ring Rotations’ (x) to cover the bale completely with plastic film.
2. Add 0.5 to this number (x).
3. Multiply this resultant figure by 2 (for 4 film layers) or 3 (for 6 film layers), 4 (for
8 layers), 5 (for 10 layers), etc.
4. Round up to the next full number if the result contains a fraction of a full
number.
Example:
Number of ‘Wrapping Ring Rotations’ to cover bale: 3.5 = (x)
Number of rotations to apply 4 layers of film to bale = (3.5+0.5) x 2 = 8
Important Notes:
 (x) ‘Wrapping Ring Rotations’ = both dispensers rotating 360° around the bale.
 The McHale Fusion 2 is a fixed chamber baler with the bale diameter usually
1230 mm –1270 mm. However, bales in excess of 1270 mm, can be produced
if any of the following conditions exist:
a) If not enough net has been applied to the bale, (especially in high dry
matter material)
b) Excessive feeding of the bale chamber, therefore not allowing the bale to
be properly compacted to its correct size.
Note:
It is very important to note that bales in excess of 1300mm will not have
enough “wrapping ring rotations” if the above exercise has been carried out on a
normal 1250 mm bale. Therefore, it is important to check the bale diameter at every
change in crop condition or in differing crop row widths and densities.
