Making of molded pulp packaging
An optimal proportion between cationic starch and AKD had been determined prior to
making of molded pulp packaging, which was produced through a hydraulic compression machine
(Pamalyn, Model PML-10) under the pressure of 2.5 bar for 3 minutes and left dried under a reflow
oven machine at 125 °C for 20 minutes. Mechanical properties in terms of compression strength
(sampling speed 30 mm./min., deformation 15 mm.) was investigated. However, all molded pulp were
conditioned at 27°C and 65% RH (representing standard condition) and 12+2 °C and 92+2 %RH
(representing cold storage condition) for 24 hours before testing.
