Food packaging from DuPont Fresher flavor, better look, greater convenience

When it comes to food and drinks, packages play a major role in grabbing consumer attention and earning brand loyalty. Protecting flavor and quality are just the beginning. Today, many consumers are also looking for brands that show environmental responsi-bility through reduced or improved packaging which means less packaging waste and spoiled foods in our landfills. Packages must also be eye appealing and convenient. We have the proven packaging solutions to help your products look and taste their best and help reduce environmental impact.

Packaging for the 21st century

Thanks to new demands for convenience, safety and environmental friendliness in packaging from the consumer side, food packagers have to look for innovative materials. The goal is to use as little packaging as possible that still stands up to the intense heat and cold food packaging is often subject to. Packaged frozen dinners are a good example – plastic packaging has to be durable enough to withstand the freezer as well as an oven without cracking or melting. And it needs to be food safe – so that chemicals from the plastic do not leach into food.

Food packaging case studies featuring Surlyn®

DuPont Food Innovations

DuPont™ Surlyn® packaging sealant resins

DuPont™ Surlyn® packaging sealant resins are puncture-proof and offer low-temperature heat seal initiation, fast tacking, and the ability to seal securely through the toughest challenges. They stand up to a variety of food industry challenges including vacuum packing to prevent leaks, sealing through food particles or grease, sealing even when wet, and many more.

Multipeel™ Flow Wrap by Südpack

Multipeel™ Flow Wrap, an innovative multilayer coextrusion film for resealable tubular bags, is the result of a two-year-long joint development project between the packaging specialists, Südpack (Ochsenhausen, Germany), and the polymer producer, DuPont Packaging & Industrial Polymers (DuPont). Südpack uses DuPont™ Surlyn® as a sealant, which is characterized by its ability to seal at very low temperatures and the very high sealing quality.Interacting with other components of the multilayer structure, Surlyn® also supports the controlled burst-peel behavior of Südpack’s Multipeel™ Flow Wrap in terms of its low initial opening force, its clean tear propagation and its maintained resealability – all important sales propositions not just for single and small households. Examples of typical applications include small-piece products such as sweets, nuts, snacks and cheese-cubes, which should not dry up after opening. Grimbacher adds: “Our core competency lies in coextrusion. We even extrude our Multipeel™ seal layer ourselves. This gives us the freedom to constantly enhance the material.”Numerous grades from the comprehensive range of Surlyn® packaging resins are available for use as a food contact or seal layer in flexible packaging. Depending on the grade selected, they are suitable for use in the highly efficient blown film or extrusion coating processes.

Securely sealed packaging that reliably preserves its contents

“The ability to seal both quickly and reliably is a basic requirement for our customers’ highly efficient, horizontal and vertical form, fill and seal (HFFS and VFFS) product lines,” explains Carolin Grimbacher, managing sharehol-der at Südpack. “This particular Surlyn® grade, jointly specified with DuPont, provides several benefits in this regard when compared with other sealants. First, thanks to its low minimum seal temperature, less heat energy is requi-red. Second, Surlyn® seals reliably over a very wide temperature range, and its hot tack strength is very high.”
