Review on IDL Packaging Bundling Stretch Reusable by Peter Parks

We use this product to store a roll of camping firewood (pine firewood) contained in a bundle. We wrapped an elastic sheet around both ends of the bundle and attached it to the belt handle. The first 2 or 3 rolls seemed good, the 4th and now the 5th roll seemed thinner, in fact they broke when we wrapped them around the bundle of firewood. We've looked up to see if we should use a tighter stretch film, but everything we've read above 80 gauge should be fine. It just seems like some of the rolls are thinner and definitely shouldn't break when you wrap them.
