Depending on the requirements, they provide an excellent barrier against oxygen, UV light, water vapour, odours, and mineral oils, while protecting the aroma and freshness of the packaged produce.
A barrier film's protective function chiefly involves protecting against outside influences and retaining desired properties or substances, typically to ensure that the aroma and taste of coffee are preserved. The question of how much protection is needed, or how much is desirable from a business standpoint, can sometimes be tricky. A complex combination of barriers is required which, in most cases, has to be tailored to the customer's specific needs. And when shelf life and visual appearance are combined to full advantage, they create a decisive competitive edge at the POS.
The film and laminates of the comprehensive BarrierPack range are tailor-made according to customer needs and can have various features, such as a transparent high barrier, antistatic properties, high sealing strength, antifog properties or special mechanical attributes. They can also be enhanced with several add-on features, including for high-quality HD flexo printing, easy opening (peelable films, laser perforation) as well as reclosability.
“Depending on the customer’s needs, the high-barrier films can be designed with or without an aluminium layer or alternatively with barrier layers made of EVOH or SiOx. Our vast range of barrier materials can fulfil basically any need or special requirement, and combine the highest possible mechanical strength with reduced material usage, following our aim to deliver cost savings and sustainability,” says Ralph Landwehr, CEO Mondi Consumer Packaging & North America. “The applications are wide ranging and include high-barrier coffee packaging, cereal packaging with an excellent mineral oil barrier, wet wipe and detergent applications, as well as pet food packaging and lidding films,” he adds.
All films are fully compliant with the relevant regulations concerning direct food contact, and are manufactured to meet the highest quality standards for hygiene and safety.
