The introduction of a new packaging material opens up the choices food companies have for sealing and displaying their products.
Denmark-based Borealis said its Borpact BC914TF branded grade of polypropylene expands the range of uses for the plastic into such applications as labelling and modified atmospheric packaging (MAP) trays for meat and fruit.
"By combining the well-established properties of polypropylene heterophasic copolymers with especially good transparency and optics, Borpact BC914TF will ensure manufacturers achieve an attractive, high-quality finish to their packaging," stated Peter Niedersüß, product development engineer for Borealis' film unit. "Consumers will benefit from the convenience of new packaging types. These include easy-open pouches replacing tinned foods."
It can be used for food pouches, peelable lidding film and film bottle labels, Borealis suggested. For example the polymer can be used to produce transparent, printed labels for bottles due to its stiffness and optics. It can also be used for printed sleeves used for fresh and frozen bread.
Its high seam strength means it can be used for retortable stand-up pouches. Its high-heat resistance means it can be used as a peelable lidding film on microwaveable food containers, the company stated.
"Borpact BC914TF is an innovative heterophasic copolymer for thermoformed, cast and blown film," the company stated. "It can deliver easy-to-process, user-friendly and attractively-finished packaging through a brand new combination of properties."
