You don’t need to read this whole article – the answer is YES.
But, in case you’re wondering why and how…
A common issue with packages requiring superior barrier properties but also wishing to give consumers a resealable feature is LEAKERS. (Learn more here!) Packaging for deli, cheese, high odor foods, products in markets with high humidity or temperatures and more require effective barrier films to preserve freshness. These films are designed with specific barrier goals in mind, and why pay for all that if a consumer-desired reseal can cause costly leakers and waste? Well, a good reseal doesn’t have to…
How can a package have a reseal feature and maintain a superior barrier property? The answer is two-fold: a reseal feature that provides barrier* as well as a non-continuous application of the opening feature. Continuous application of reseal features requires both a cut through the end seals AND sealing through the feature and end seals, resulting in barrier failures. (Read more about seal temperature variance and leakers here!)
The Barrier Plus System
Continuous application is quite common for reseal feature application in the packaging world, and leaker issues in the seal area for packaging requiring superior barrier are equally prevalent. Sealstrip has designed a barrier plus system for reseal packaging to reduce leakers. The Barrier Plus System combines two system upgrades: first, the resealable package opening feature is an intermittent slit that does not violate the end seals and second, a customized barrier tape is continuously applied over the opening, designed to meet the specific barrier requirements of the packaging film and maintain the package OTR and WVTR properties.
You can maintain superior barrier properties AND please your consumers with resealable packaging!
Did we mention this reliable Sealstrip resealable feature is also easy open, tamper evident, with custom printing options and FDA direct food compliance options? And the entire system is retrofit to your existing wrapper or bagger and runs at line speeds? Recyclable solutions are also on the horizon - your package's future awaits!
