Sensus is the first in the Zip-Pak family of resealable closures called Sensory Feedback Fasteners. They feature performance characteristics that appeal to a consumer’s sense of sound, sight, smell or touch. The Sensus re-closure profile is specifically designed to create a tactile bumping sensation and audible clicking noise when the zipper is opened or resealed. These tactile and audible prompts provide consumers complete assurance that their flexible package has firmly been sealed, and alert pets, with a heightened sense of sound, that it’s time to eat.
