have you got a new roll? toss it on some scales. my curiosity has peaked.
one of the brands i didnt like was from a local supply company. i weighed it before opening, #55 lbs. made it real easy to handle but found out real fast it was a bad idea. i normally put 2.5 laps on for coastal. it popped as the gate was opening. 2 bales later wound up getting to 5 laps to hold it together. even then had to handle very gingerly. after 9 months outside the top of the bales are bare, no net. had to move to cows with pallet forks.
Besides being weak net it sounds like it had no UV protection adde to the plastic
