They’re the foods we love during the holiday season – turkey, ham, lamb, fish and cheese, to name a few. How do these delicacies stay fresh during transport from food packers to supermarkets and finally to our dining tables?
The secret is multi-layer film that prevents oxygen from entering the package, thereby preventing spoilage. These multiple layers of polymers are bonded together by special adhesives such as Plexar polyethylene tie-layer resins from LyondellBasell. They help to create the oxygen barriers necessary to extend the shelf life of fresh foods.
Plexar resins were the first tie-layer adhesives developed in North America more than 35 years ago. Today, they remain the leading tie-layer resins on the market.
Over the years, LyondellBasell has developed new tie-layer resins that provide stronger interlayer adhesion without compromising clarity. As a result, the interface between the tie-layer and the barrier resin is virtually seamless. This enables packaging converters to produce clear film that helps consumers see the packaged foods easier.
“We’ve maintained our leadership in this market because we offer exceptional technical expertise, reliable supply and cost-effective products that provide outstanding performance,” said Bill Podborny, R&D application development and technical support at the Cincinnati Technology Center.
