Finding these rolls have saved us a ton of money as VacMaster price is the best we have ever found. The mesh inner strip allows for complete vacuum every time and with the quality and thickness of the material, we expect and get close to 100% long term success. We use an old, nozzled, Italian machine and these meshed rolls are so much better than the textured ones. Finding these meshed products have literally revolutionized our vacuum process and success rate. We are sad to see they are being closed out. Try them. You will not be disappointed.
