1. Certain mechanical properties. Packaging materials should be able to effectively protect the product, it should have a certain strength, toughness and flexibility, to adapt to pressure, impact. The influence of static and dynamic factors such as vibration.

2, isolation performance. According to the different requirements of product packaging, packaging materials to deal with moisture, water vapor, gas, light, aromatic gas, odor, heat, etc. have certain barrier.

3. Good safety performance. Packaging materials of their own toxicity should be small, so as not to pollute the product and affect human health, packaging materials should be non-corrosive, and with pest control, moth, rodent control, inhibit microorganisms and other properties to protect product safety.

4. Suitable processing performance. Packaging materials should be suitable for processing, easy to make a variety of packaging containers should be easy to packaging operations mechanization, automation, to adapt to large-scale industrial production should be appropriate for printing, easy to print packaging signs.

5. Good economic performance. Packaging materials should be widely sourced, easy to draw, low cost, the use of packaging materials and packaging containers should be easy to handle, do not pollute the environment, so as to avoid causing public hazards.
