A new PP film grade from Borealis is said to offer opportunities for cost effective production of film to be used in adhesives and packaging applications. BA110CF is claimed to provide films with superior performance compared to standard products. Suitable for all siliconization processes, it reduces production costs for converters by eliminating the need for different sealing films depending on the siliconization process required for a particular end product, the company promises.
In addition to its all-round siliconization benefit, BA110CF is said to offer good processing on blown film lines. Its high curing ability, when the silicone layer is applied in a liquid state, can increase processing efficiency for converters. The “ideal combination of additives and product conditions ensures good long term adhesion between the silicone layer and the film”, it is claimed. “This helps to maintain a film’s performance over a longer lifetime and avoids traditional adhesion issues experienced with standard products.”
The key characteristics of BA110CF is said to allow converters to produce films with a range of performance advantages compared with paper. Its high stiffness/good toughness ratio ensures greater mechanical strength, says Borealis. This makes the film more suitable, for example, as a carrier sheet for industrial applications where extra force needs to be applied to release tapes and labels. This improved performance is said to reduce the potential for waste and production run interruptions at the converter.
The higher water vapour barrier of PP film reduces water absorption, which, in combination with the high heat resistance characteristic of BA110CF, also increases its suitability over paper for medical applications requiring sterilization. The film offers greater microbe resistance than paper, making it attractive for both medical applications and high end sectors, such as the semiconductor industry.
