1, a certain degree of mechanical properties packaging materials should be able to effectively protect products, so should have a certain strength, toughness and elasticity, etc., in order to adapt to pressure, impact.
The influence of static and dynamic factors such as vibration.
2, barrier performance according to the different requirements of product packaging, packaging materials to deal with moisture, water vapor, gas, light, aromatic gas, odor, heat and so on has a certain block.
3, good safety performance packaging materials themselves less toxic, so as not to pollute products and affect human health, packaging materials should be non-corrosive, and has anti-insect, moth-proof, anti-rodent, inhibiting microorganisms and other properties, in order to protect product safety.
4, the appropriate processing performance packaging materials should be suitable for processing, easy to make a variety of packaging containers should be easy to packaging operation mechanization, automation, in order to adapt to large-scale industrial production should be suitable for printing, easy to print packaging signs.
5, better economic performance packaging materials should be a wide range of sources, convenient material, low cost, after the use of packaging materials and packaging containers should be easy to deal with, do not pollute the environment, so as not to cause public hazards.
