Innovia Films has introduced a new high-speed BOPP film, Propafilm REF, a new co-extruded material that compliments the company’s 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 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 over a larger range of temperatures. Combined, these two properties enable Propafilm REF to be ideally suited to horizontal-form-fill wrapping applications.
“Whilst speed is important to our customers, efficiencies are just as critical. Minimizing rejects and maximizing outputs remain an important objective for many of our clients. Propafilm REF can contribute to these targets,” says Amaia Cowan, Innovia Films market development manager. “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.”
The film also provides excellent clarity for visual impact and good moisture barrier for product protection. It is suited for a variety of applications and markets, such as biscuits and bakery, confectionery, dried foods, tea and cosmetics.
