Mechanical pulp is the material of choice – as a base material or additive – in order to increase the stiffness of cartonboard products (e.g. for cereals or cigarette packs). Although successful, this material is costly, hence the Seeker is looking for an alternative material that can lead to a cost reduction whilst achieving the same stiffness.
This is a Reduction-to-Practice Challenge that requires submission of written documentation. The Seeker will perform experimental validation of proposed solutions in order to determine the award.
White lined chipboard (WLC) and folding box board (FBB) are two multilayered cartonboard products used in many packaging applications. Mechanical pulp is the material of choice for the composition of such products in order to provide the much needed bending stiffness. This is a key mechanical property of the cartonboard that has a two-fold implication:
Hence it is very important for a papermaking company, such as the Seeker, to carefully monitor this parameter and ensure that the optimum stiffness can be achieved at the lowest possible cost.
Often, recycled fibers are also used in the composition of cartonboard products but, as a result of the recycling process, these have reduced bulk and strength and, consequently, diminished bending stiffness. This is compensated through the addition of mechanical pulp. Although successful in increasing the bending stiffness of the board, this solution comes at a high cost. Therefore, the Seeker is interested in finding a novel material or additive that can be used in the composition or structure of WLC and FBB and cost-effectively replace mechanical pulp.
Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on August 6, 2017. Late submissions will not be considered.
What is an RTP Challenge?
An InnoCentive RTP (Reduction to Practice) Challenge is a prototype that proves an idea, and is similar to an InnoCentive Theoretical Challenge in its high level of detail. However, an RTP requires the Solver to submit a validated solution, either in the form of original data or a physical sample. Also the Seeker is allowed to test the proposed solution.
