High Speed BOPP Film
As overall production costs are scrutinized, achieving high efficiencies is becoming increasingly vital. In response to this, Innovia Films Ltd., Wigton, UK, introduces its latest high speed Biaxially Oriented Polypropylene (BOPP) film - Propafilm REF. This new coextruded material compliments their 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.
The new material 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.
Innovia has been able to validate their laboratory findings with actual packaging machinery trials. SPS Italiana Pack systems (PFM Group), was one of the partners chosen to confirm the film’s performance. “We ran Propafilm REF on our Modulo machine and we can confirm that speeds of 80 m/min were achieved, a substantial 30 m/min improvement. At these speeds, the film was still passing our stringent micro-hole acceptance level (i.e.200 mbar/20 sec. pillow bag configuration),” says Roberto Spatolisano, Project Manager from SPS.
According to Innovia, Propafilm REF, besides offering excellent machinability, also provides excellent clarity for visual impact and good moisture barrier for product protection. It is suited to a variety of applications and markets such as biscuits and bakery, confectionery, dried foods, tea and cosmetics.
