Overview

Areas of Investigation• Characterization of physical property influences on

lifetime of corrugated containers in cyclic humidity environments, formulation of lifetime predictive models, effects of lateral and liner corrugating on lifetime

• measurement of physical properties of corrugated board: shear stiffness, characterization of localized buckling in compression, FEA modeling (with GT CEE) of non-linear behavior, optimization of strength properties through component densification

• Wax replacement alternative coatings effectiveness and development including pigmented coatings, exploration of electrospinning and EHD spraying technologies

Creep measuring equipment

BCT creep 8 stations, 50 – 80% RH 24 hr cycle - used to obtain multiple regression models for lifetime prediction.

ECT creep, 12 stations, 50 – 80% RH 5 hour cycle - applied to the A flute varying medium basis weight set to compare with BCT creep

Corrugating double backer simulator – investigates adhesive type and application technique effects

Gravure roll glue applicator is being retrofitted to be a thin film metered roll applicator to simulate Kohler device

Single face sample carriage moves left to right Timed IR preheater

Roll or other Glue applicator

Timed heated press

Property measurement development:qualifying new methods for board quality control

IPST custom built torsion pendulum – measures the torsion stiffness of twisting samples 12 x 2.5 “

=?

Newly introduced BQM tester measures shear stiffness of corrugated board nondestructively – has been shown to correlate to torsion pendulum

based measurements

Measurement of board shear stiffness is sensitive to crushing which can impact box strength 10 – 15% and lifetime to a greater degree – area currently under investigation

IPST robot-based ultrasonics set-up provides a complete measure of the in-plane physical constants

L&W TSI is available in Autoline units replacing test labs and can be used for many applications: replacement of Ring Crush, bending stiffness, predictor for score-cracking

?

Wax alternative coatings • evaluation of polymer coatings, coating application techniques, surface treatment technology, effects of polymer replacement by pigment amount and pigment type

Electrospinning of polymer solutions provides a high transpiration but water resistant film displaying superhydrophobicity

Linerboard can have a base clay coat followed by a polymer top coat - both applied by Mayer rod coater

Clay base-coated linerboards are shown to corrugate well on the IPST pilot corrugator and perform well in a simulated

end-use ice-pack test (above)

SEM shot showing Nanoscale roughness from electrospinning – opportunity for high water resistance at reduced coat weight compared to other technologies
