What is the characteristics of the plastic packaging container 2012

(1) plastic density is small, light, transparent or not transparent. (2) easy to processing, as long as the replacement of mold, can get different kinds of containers, and easy to form the mass production. (3) the packaging effect is good, the plastic variety, easy coloring, bright color, can according to need to make different kinds of packaging containers, achieve the best effect of packaging. (4) has good corrosion resistance, acid and alkali resistant, oil resistant, impact resistant performance; And has good mechanical strength. Plastic packaging container also has its disadvantages, such as plastic deformation at high temperature, so the temperature limit; The container surface hardness is low, easy to wear or cut; In light of oxygen and heat under the action of oxygen, plastic produce degradation, crisp, the ageing phenomenon such as performance degradation; Electrical conductivity is poor, prone to electrostatic accumulation, etc
