went helping a friend feed his cattle and he had bought some bales that had film instead of net. used the bale spike. we dropped the bale and opened the black plastic at the plastic heap and left the film on. biggest mistake we made. dont know if there's too little layers of film or what (bale was nice and solid) but as soon as we lifted it, the film disintegrated under the weight pretty much and half the bale came of the bale spike. happened a couple of times. had to cut the plastic off by the feed barriers while keeping it on the spike. based off that i reckon net would be stronger but i hope that it wasnt too little of the film put on.
did see last year they did seal the bale better.one of the bales out of the heap had a tear in the black plastic but when we opened, very little mould to be found.
way i see it, film on film seems to benefit the lads with bale shears the most. if with a normal bale spike, be more than likely taking the plastic off 1st and then taking the open bale to the feeders and if its true that some of the recycling centres refused to take the film mixed in with the plastic, defeats the purpose really. on the side of keeping mould out of bales, 16 wraps minimum and keep handling to a minimum. less you handle the bale when wrapped, the better
