Unit Pack is a study of effective package design. The EASY TEAR TIP is just that, easy to tear. Once the package has been opened, a metering channel remains. The channel provides directional control and is designed with an iris tip. Squeeze gently and the channel opens. Stop squeezing and the iris closes, protecting your product. The three dimensional shape and flexible wall assures easy and complete dispensing. The film of the body will not crease or pin hole and strong radio frequency welding insures the package will survive abuse. Your product remains in perfect condition.
