Elplast, manufacturer of resealable El-Zip press-to-close zippers, has released new audible resealable zippers for pet food packaging. The new zippers have added sound features. When a resealable pack is opened, it creates an audible opening noise at the correct frequency to attract pets. This means dogs and cats can hear from some distance when it’s meal or treat time. The zippers are specially designed with extra cross-ribs to give off sound when opening and closing. This also reassures users that the pack is securely closed to preserve freshness. The double profile creates strength and means that pets are unable to open the pack independently. Elplast zippers for pet foods are available in endless variations including triple-profile, retort-capable, differentiated opening forces and colored zippers to match pack design. They can be used with all commonly used packaging machinery, packaging processes and package styles and types.
