Velcro is not a physical product. “Velcro” is a group of companies (including Velcro USA Inc) that manufactures a wide range of products. Velcro tape alternative hook and loop works by having two strips of material, one with lots of tiny hooks, and one with lots of thinner loops that the hooks can cling to when the two elements are pressed together. Standard industrial strength hook and loop has an average peel strength of 1.2 lbs. per inch of width (PIW) and average shear strength of 14 lbs. per square inch (PSI).
