Valve-Free Formats Remove The Component That Fails
Valve-free roll compression bags grow at 9.0% against 6.0% for the category by eliminating the one-way valve that accounts for roughly 61% of vacuum losses. Air is expelled by rolling the bag from the closed end through a channel that seals as it passes, which requires no appliance, no vacuum cleaner and no moving part. The trade is a less complete evacuation and a physical effort the user must supply, which is why retail merchandising still favours the format that looks more sophisticated. It also costs less to manufacture, which is an unusual combination in any category.
