Torque is the force required to turn an object around an axis and in the case of plastic caps and closures, torque refers to the ease at which a cap is screwed on and off the neck of packaging.
Application torque is the force required to apply the cap and release torque refers to the force required to remove the cap. When torque is high, the application and release of the cap can become difficult and can result in a poor seal or breakage of the closure.
Our torque release additives reduce friction in plastic caps and closures to allow easier application and removal of the part. These bio-based, high stability additives ensure more efficient processing in a range of packaging applications. Our additives are recommended for use at very low addition levels and are recommended to be dosed via a masterbatch or compound.
Incroslip™ Torque Release Additives for Caps and Closures
Incroslip™ range are manufactured using proprietary processes, that offers processors and end-use flexibility, performance and better-quality plastics, whilst also providing exceptional stability with reduced odor and color degradation versus standard slip additives. Incroslip™ additives are bio-based* and sustainably produced to deliver both performance and sustainability benefits to the final part.
Some key benefits of the Incroslip™ range are high slip performance with improved stability, high temperature performance, and low taste and odor.
Case study: Reduced taste and taint issues in caps
A manufacturer of bottled water approached us to help recommend a product to reduce poor organoleptic properties in their HDPE caps. Their current solution was a standard fatty acid amide torque release agent, but this was not giving them the stability performance they required.
The manufacturer was using an ozone sterilization process on the caps, so we suggested using Incroslip™ Q, a tailored solution that offers excellent torque release and oxidative stability. Incroslip™ Q can minimize taint and taste issues while providing the level of torque release force required to easily remove caps.
Incroslip™ Q helped the manufacturer to balance good organoleptic properties through the ozone sterilization process and good cap closure properties to ensure a well-received consumer product.
