SaFTFlo® Tamper Evident Insert

SaFTFlo® Tamper Evident is a secondary safety check for our closed-loop system. An HDPE collar with lugs snaps to the bottom of the insert substrate to provide a secure connection, preventing unintended removal of the bottle insert.  

When an insert with the Tamper Evident collar is inserted into the bottle, the lugs expand open under the bottle neck, making it virtually impossible to remove the insert from the container. It can withstand a pulling force of 70lbs, 50% stronger than any competition in the market.  

To establish chemical flow, the end user replaces the ship cap with a SaFTFlo® Cap Adapter which opens the insert valve, releasing chemical. A fully closed-loop system ensures that end users are never exposed directly to chemical concentrate.
