Performance requirements of packaging materials

Packaging materials refer to materials used for manufacturing packaging containers, packaging and decoration, packaging and printing, packaging and transportation. It includes main packaging materials such as metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, chemical fibers, composite materials, and auxiliary materials such as paint, adhesive, adhesive tape, decoration and printing materials.

Some mechanical properties

Packaging materials should be able to effectively protect products. Therefore, it should have certain strength, toughness and elasticity to adapt to the influence of static and dynamic factors such as pressure, impact and vibration.

Isolation performance

According to the different requirements of product packaging, packaging materials should be resistant to moisture, steam, gas, light, aromatic gas, odor, heat and so on.

Good safety performance

The toxicity of packaging materials should be small to avoid polluting products and affecting human health; Packaging materials should be non-corrosive, and have insect-proof, moth-proof, rat-proof, microbial inhibition and other properties to protect product safety.

Suitable processability

Packaging materials should be suitable for processing and easy to be made into various packaging containers. The mechanization and automation of packaging operation should easily adapt to large-scale industrial production. It should be suitable for printing and convenient for printing packaging marks.

Better economic performance

Packaging materials should be widely available, easy to obtain and low in cost, and the used packaging materials and containers should be easy to handle and not pollute the environment, so as not to cause public harm.

Correct use

The correct use of packaging materials is related to the cost and safety of product transportation. Packaging products with suitable packaging materials can save a lot of money, and can protect products with the lowest cost.
