Innovia introduces new BOPP film for packaging applications

Innovia Films has introduced its new high-speed biaxially oriented polypropylene (BOPP) Propafilm REF that can perform on different machines at improved speeds.

Innovia Films has introduced its new high-speed biaxially oriented polypropylene (BOPP) Propafilm REF that can perform on different machines at improved speeds.

The new film is expected to complement Innovia’s wide range of high-speed materials and provide more options to its customers.

Innovia Films market development manager Amaia Cowan said: “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.”

The company noted that Propafilm REF provides a wide sealing range, compared to standard coextruded films. 

Scientists have confirmed that the film has more than 30°C lower heat seal threshold compared to basic films, at standard laboratory conditions.

Additionally, the film exhibited an improved hot tack performance over standard films that enable it to remain intact on a larger range of temperatures. 

Innovia Films claims that these attributes make Propafilm REF suitable for horizontal-form-fill wrapping applications.

SPS Italiana Pack systems (PFM Group) carried out testing to assess the film’s performance.

Commenting on the testing, SPS project manager Roberto Spatolisano said: “We ran Propafilm REF on our Modulo machine and we can confirm that speeds of 80m/min were achieved, a substantial 30m/min improvement.

“At these speeds, the film was still passing our stringent micro-hole acceptance level (i.e. 200mbar/20s pillow bag configuration).”

The film offers enhanced visual clarity and works as a good moisture barrier, making it suitable for various products such as confectionery, bakery, dried foods, tea and cosmetics.
