Packaging materials have evolved to meet new demands today’s snack and bakery market. A desire for longer shelf life paired with fewer preservatives in the foods and healthy eating overall has prompted the need for lightweight packaging, thinner barrier materials and convenience features on thinner, more-sustainable substances. Because the consumption cycle of packaged foods is growing longer, the packaging needs to work harder to preserve and extend the freshness of perishable products.
Food safety and freshness are key design criteria for food packaging, so packages that effectively reseal are gaining popularity, according to Heather Turner, North America marketing manager, Dow Packaging & Specialty Plastics, Midland, MI. “We are seeing more emphasis on packaging that helps extend food shelf life and maintain freshness. For snack foods especially, individually sized, preportioned packages are gaining traction, as well as more sustainable options because they help reduce food waste.”
