Effects of Application of Wood By-products to Hot Pressed Pulp Mold

Abstract

The hot pressed pulp mold is one of the promising packaging materials as an alternative plastic packaging material since the hot pressed pulp mold not only is made with natural wood fibers but also has relatively high mechanical properties and good surface properties. Although the hot pressing drying process of the hot pressed pulp mold could increase strength properties, the bulk and the bulk related properties such as insulation could be deceased. In order to increase the applicability of the hot pressed pulp mold, this study assessed the effects of application of the different types of wood by-product such as bark and leaves, on the bulk and the tensile strength of hot pressed pulp mold. The addition of wood by-products resulted in the increase of bulk but the decrease of tensile strength. The loss of tensile strength was compensated by the addition of starch as a strength additive.
