This study aims to assess the plastic processing potential of a three-dimensional con- tainer utilizing a composite material composed of wood veneer and paper. The selection encom- passed five distinct species, namely oak, tulip tree, ash, spruce, and pencil cedar. To counteract tensile failure in the wood veneers, a water-soluble acrylic resin was applied to both sides of kraft paper, which was subsequently dried and laminated onto the wood veneers. This assembly was pre-heated at 130°C for 5 minutes under pressurized conditions, yielding a malleable sub- strate suitable for plastic processing experimentation. The findings indicated an augmented plas- tic workability at elevated temperatures. Following preheating, an incremental extension of the initial pressing duration was observed, succeeded by a reduced duration for the subsequent pressing phase, culminating in favorable workability. Upon completion of the molding process, subjecting the material to rapid cooling and moisture exposure resulted in enhanced stability and plastic working performance devoid of defects, contrasting with outcomes observed during gradual cooling and controlled humidity conditions. Consequently, this investigation establishes the feasibility of extending plastic working to a broader array of tree species, contingent upon meticulous calibration of manufacturing parameters congruent with the inherent tissue structure of each tree species.
