1. Press the cell structure classification can be divided into the openings in the foam and closed cell foam categories: opening foam cell communication between each other, mutual ventilation, foam in the gas phase in a continuous phase polymer phase fluid from the body by foaming. As for the degree of difficulty with the polymer fluid through their own characteristics and the degree of opening. Closed cell foam is a cell in isolation, evenly distributed in the foam body, mutually connected, completeness bubbles break, the cell wall to form a connection with the foam. Two actual foam cell structure exist, namely open cell structure foam body with closed-cell structure, closed-cell foam body structure with an open cell structure. If the open cell structure accounted for 90% -95%, foam insulation box cucumber boxes, called open-cell structure of the foam body foam, otherwise known as closed-cell foam structure. Closed-cell structure on the mechanical properties of the foam is large, foam insulation box fruit boxes, is an important structural parameters of foam products. Foam packaging foam packaging design process is the use made of foam packaging. General bubble wrap is defined by the polystyrene processing of raw materials produced by the mold by hot foam packaging products. Abstract technique used for amenity, using abstract geometric patterns color or texture of the composition of the picture result, foam insulation box, you need to text and packaging design packaging design packaging products to co-ordinate thinking generally produce white color. Polystyrene is the ideal packaging material, by molding process, can be processed into various shapes according to needs, different thickness of packaging products. At higher load conditions material can be decomposed by absorbing deformation energy to cushion the shock absorption and other effects, but also has insulation foam packaging function. Foam insulation box, can be customized. Foam insulation foam box _ _ much foam box incubators blueberries from Shandong great foam Limited.
