A new high performance lidding film for sandwich packs which combines excellent barrier properties with easy peel has been launched by Surface Specialities.
PropaLid is a biaxially oriented polypropylene (BOPP) film which is said to provide a strong but easy peel seal to APET, CPET or PVC sandwich packs for extended shelf life.
Cost-effective in comparison to competitive substrates, the film provides a high barrier to water vapour, gases and aromas. It is heat sealable on both sides. It is also extremely glossy and has anti-mist properties for improved pack presentation. One side of the film is printable and the other features Surface Specialties' unique peelable seal coating.
Surface Specialties business development manager, Colin Fisher said: "We have combined all the features required for sandwich pack lidding into one film to offer a competitive alternative to the other substrates currently available on the market."
The new film was developed at Surface Specialties' €12 million Research & Development Centre at Wigton, UK - said to be one of the most advanced of its kind in the industry.
It is anticipated that PropaLid will be the first of a series of lidding film developments to take advantage of the unique properties of BOPP film developed through Surface Specialties' coating expertise.
The advantages of bubble-produced BOPP for labels is the film's balanced orientation which gives high machine direction stiffness and tensile strength for high speed conversion, die-cutting and matrix stripping.
