1, the mechanical properties of certain packaging materials can effectively protect the product, so we should have a certain strength, toughness and elasticity, in order to adapt to the pressure, vibration and impact. Effects of static and dynamic factors.
2, the barrier properties according to different requirements for product packaging, packaging materials with water, steam, gas, light, aroma, smell, heat has a certain barrier.
3, good safety performance of packaging material itself is less toxic to avoid pollution and affect human health products; packaging materials should be non corrosive, and with insect proof, mothproof, anti rat, inhibit microbial properties, in order to protect the safety of products.
4, The processing properties of packaging materials 4, right should be easy to be suitable for processing, mechanization and automation, easy packaging operation made of various packaging containers, in order to adapt to the large-scale industrial production should be suitable for printing, convenient packaging and label printing.
5, good economic performance of packaging materials should be extensive sources, convenient, low cost, packaging materials and packaging containers after use should be easy to handle, do not pollute the environment, so as to avoid the pollution.
