StePac launches lean and fully recyclable top seal solution

Fresh produce packaging innovators, StePac Ltd. has expanded its range of top seals with new solutions to boost the retail fresh produce packaging sector. Its newly upgraded portfolio includes lean and fully recyclable easy peel film structures designed to be sealed onto trays or containers housing produce items such as summer fruits, freshly cut fruits and vegetables and more for on-the-go convenience.

The user friendly and appealing films are engineered with StePac’s flagship Modified Atmosphere Packaging (MAP) condensation control technology, rendered with capabilities to significantly extend the shelf life of fresh produce and designed to preserve their quality and nutritional value. Its built-in modified atmosphere properties slow respiration inside the packaging, effectively delaying the ageing processes and inhibiting microbial decay.

“We are leading the transition from the use of traditional clamshells for packaging fresh berries to leaner, greener and more attractive top-seal solutions,” notes Gary Ward, PhD, Business Development Manager for StePac. “This shift is designed to award multiple benefits. Firstly, it generates as much as 25-30 per cent reduction in plastic use as it is a leaner product compared to the commonly used clamshells. Secondly, it is fully recyclable and thirdly, it provides shelf-life extension properties, enhancing food quality while reducing waste, all of which fall in line with our sustainability strategy. Last, but not least, it also ensures food safety.”

The top-seal is comprised of a laminated structure composed of two layers, with a pressure-sensitive adhesive in between. A die-cut in the lower film layer, opens up a window that displays the produce packed in the tray and can be cut to the desired dimensions. The adhesive between the two layers is sufficiently strong that the upper layer of film can be peeled and resealed to the lower layer up to 20 times making it ideal for multiple servings, and can be applied to PET and PP trays as well as eco-sustainable materials. Each time it is resealed, the Modified Atmosphere (MA) activity regenerates and continues to preserve the quality of the food inside the consumer’s fridge.
