Propafi lm highlighted at Düsseldorf expo
Germany Innovia at Interpack spotlighted some of its most valued biaxially oriented polypropylene (BOPP) solutions, including its Propafilm portfolio.
The new coextruded Propafilm REF complements the company’s established range of high-speed materials and increases the options for its customers.
Propafilm REF was designed with speed in mind, according to Innovia. The product presents a wide sealing range, when compared with 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 with basic films.
The film additionally provides an enhanced hot tack performance over standard films, so that seals, when pulled still hot, resist opening on a larger range of temperatures, helping make Propafilm REF ideal for horizontal-form-fill wrapping applications, said Innovia.
Amaia Cowan, market development manager, Innovia Films, said, “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.”
This film, 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.
Innovia highlighted its overwrap films, with “a proven record on high-speed overwrapping machines” without compromising shelf appeal.
