Innovia Films Ltd, a major producer of specialty BOPP films based in Wigton, UK, recognises that today’s competitive market place demands packaging films that perform on a variety of machines, at the highest possible speeds.  As overall production costs are scrutinised, achieving high efficiencies is becoming increasingly vital.  In response to these trends, Innovia is pleased to introduce its latest high speed biaxially oriented polypropylene (BOPP) film - Propafilm REF.

This new coextruded material compliments its already well-established range of high-speed materials and increases the options for its customers. Propafilm REF was designed with speed in mind.  The product presents a wide sealing range, when compared to standard coextruded films.  At typical laboratory conditions, scientists have been able to confirm over 30°C lower heat seal threshold (the minimum temperature required to achieve acceptable seal strength of 200g/25mm) compared to basic films.In addition to the wide seal range, this film also provides an enhanced hot tack performance over standard films.  This means that the seals, when pulled still hot, resist opening on a larger range of temperatures.  Combined, these two properties enable Propafilm REF to be ideally suited to horizontal-form-fill wrapping applications.

Amaia Cowan, market development manager at Innovia Films, commented: “Whilst speed is important to our customers, efficiencies are just as critical. Minimising rejects and maximising outputs remain an important objective for many of our clients. Propafilm REF can contribute to these targets. With its higher COF in the inner surface of the film, product movement within the pack can be reduced during the feeding stages, protecting seal damage and allowing good pack integrity to be maintained. Strong seals are achieved every time.”
