Process Optimization of Biomass Cushion Packaging Products and Its Properties

Biomass materials are the best substitute for those made of plastic packaging materials in the world,widespread application of these materials can control or eliminate the increase of white pollution problem effectively in the world.The process conditions of the biomass cushion packaging material,such as up mold temperature,down mould temperature,dry time and the holding time etc,are studied by using orthogonal test method.The results show that the biomass cushion packaging material had the maximum tensile strength 1.98 MPa under the process conditions of up mold temperature 235 ℃,down mould temperature 230 ℃,dry time 45 s and the holding time 50 s.As increase of the up temperature and the drying time,the cushioning coefficient presents firstly decreases and then increases,the cushioning coefficient reached minimum under the process conditions of up mold temperature 235 ℃ or the holding time 50 s.Compared with the conventional plastic packaging materials,the biomass cushion packaging materials has the advantages of good strength and cushioning property.So it is the best substitute of the plastic products.
