Our patented design eliminates the need for internal baffles by providing more surface area on the base versus a square or rectangular base. This creates a more stable base and combined with our extra vertical reinforcement in the sidewalls the rounding effect is reduced. In addition to greater stability, the iPAQ holds approximately 10% more than a traditional bag of the same footprint. Another benefit is the ability to use liners in the iPAQ and the bottom design reduces bridging issues in many products and empties more complete than traditional bottom designs.
