Was it a remnant or did you by it off the roll? If it was cut to size in the shop it should'nt have been on the boom of a fork lift. They only use those for lifting the full rolls at the ware house and with the card board roll in the center, if it did get a bang of the boom it would go right through it if they did'nt go in at the right angle. Get some spray glue off them, or copy dex or even if you know how to heat seam it? When your fitting it maybe flip it 180 if you cant get it out in the waste on way, may get it the other. They would ofcourse be obliged to replace it but if you cut it you own it.
