Some tips for Bale Wrap Film
Handle the plastic after due thoughtfully. Throwing rolls around will probably damage the plastic, making
it impossible for the cover to unroll properly.
In hot weather, keep the roll boxed and inside a shaded area until necessary. This will limit excess tack
being subtracted from the plastic. Film that may be very tacky will cause tack build on the stretch model
rollers, and result inside the film ‘necking down’
Maintain your rollers clean using Bale Wrap Film. Some tack will stick to the rollers whatever ways are
taken, so make sure that they are cleaned by using a white spirit between roll changes in the event the
weather is hot. Soiled rollers will affect grow percentage, and cause a lot of neck-down on the bale.
To measure how the correct amount of stretch is being achieved, mark or tape only two points
horizontally 10 inches apart around the roll after pulling the wrap with the pre-stretcher. Measure the
distance once the wrap has been applied to the bale. For conventional film like Silawrap, 55% stretch
means a reading of 15. 5 inches and 60% means a reading of 16 inches.
To check neck-down, the width of wrap around the bale should be 580mm to 610mm for 750mm (30
inch) cover, and 380 to 410mm pertaining to 500mm (20 inch) cover.

2. Always wrap bales within just 2 hours of baling.
If wrapping inside the field, move bales towards the stack straight after gift wrapping.
Follow to the Bale Wrap Film manufacturer’s recommendations for setting up the machine.
On single Bale Wrap Film, be sure that the centre of the particular bale and centre of the roll of film are
generally horizontal. Take into account diverse bale sizes and adjust the height of the psu accordingly.
To ensure that 6 layers of video are applied, count the volume of revolutions it takes to fully cover the
bale as soon as. Add one more as well as repeat twice.
So, if it will require 7 revolutions to cover the bale once, create 1 (= 8) as well as multiply by 3. As a
result, 24 revolutions are had to apply six layers associated with film.
On in-line wrappers, the volume of layers applied is adjusted by altering the volume of inches the bale is
actually moved forward per revolution of the hoop. To apply 6 layers by using an inline wrapper (with 2
pre-stretchers) having a 30 inch (750mm) spin of film, adjust to your 5-inch movement. (30inches
divided by 6 layers).
