If you received your order you may know is there is a seam connecting your custom clear tarps together. This may seem like a defect or a inferior way of producing tarps, but in fact it's the industry standard and the only way to attach clear material for large clear sheets. We also make sure we inform all customers of this heat seal on every Amazon page (please see image below). Please watch this video below for more detailed information. After you watch the video, please circle back to your AKON representative so that we can make sure you are properly taking care of.
