C-Flex® EZ Top® container closures

EZ Top® container closures are one-piece units consisting of tubing and an overmolded stopper. Economical and designed for single use, these closures eliminate contamination that can occur with repeat-use closures and play a key role in the reduction of cleaning and assembly time. One-piece construction – which employs a thermal bond between tubing and stopper – eliminates product loss and contamination due to loose connections.
