Material and cost savings combined with puncture resistance and environmental advantages are claims made by Bollore for its newly-launched range of ultra-thin polyolefin shrink films.

The France-based company said its four new BTT films offer the same performance as conventional thicker film.

“Our range of BTT films are ultra thin but that are perfectly resistant and adapted to high-speed machines,”​ Fabian Theuriet, France export manger, told FoodProductionDaily.com at the Interpack trade show in Dusseldorf. “For example, the 11-micron film can be used in applications where it was not possible before.”

The materials achieve enhanced performance because of application of high-tech resins, including the latest generation of metallocenes, he added.

Developed to seal and quickly at low temperatures, the films are suitable for a range of applications, including with fruit and vegetables and as shrink wrap secondary packaging.

Properties

The BTT +90 is a multilayer film that boasts “outstanding yield” and can be used at high speed. The crosslinked BTTX 110 offers high impact strength, a broad sealing window and the same mechanical properties as a 15-micron film.

The BTT+ 125 is a multilayer film that offers instant sealing, rigidity and high shrinkage at low temperature. Soft shrink, high elongation and tear resistance are characteristics of the BTTXF 130, said Bollore.

Benefits

The company said the thinner film also realises tangible environmental and production benefits.

“With longer footage on each roll, less production stops occur,”​ said the French firm, which employs 30,000 people worldwide.

It added: “Less waste is generated. Less empty packaging materials have to be managed and less trucks are need for transportation – thus minimising the carbon footprint.”
