Packaging materials refer to materials used in the manufacture of packaging containers, packaging and decoration, packaging printing, packaging and transportation, etc. to meet product packaging requirements, including metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, Main packaging materials such as chemical fibers and composite materials, as well as auxiliary materials such as coatings, adhesives, strapping tapes, decoration, and printing materials
1. Certain mechanical properties
Packaging materials should be able to effectively protect the product. Therefore, it should have certain strength, toughness and elasticity to adapt to pressure and impact. Effects of vibration isostatic and dynamic factors.
2. Insulation performance
According to different requirements for product packaging, packaging materials should have certain barriers to moisture, water vapor, gas, light, aroma, odor, heat, etc.
3. Good safety performance
The toxicity of the packaging material itself should be small, so as not to pollute the product and affect human health; the packaging material should be non-corrosive, and have the properties of insect-proof, moth-proof, rodent-proof, and microorganism inhibition to protect product safety.
4. Appropriate processing performance
Packaging materials should be suitable for processing and easy to be made into various packaging containers. It should be easy to mechanize and automate packaging operations to adapt to large-scale industrial production. It should be suitable for printing and easy to print packaging signs.
5. Better economic performance
Packaging materials should come from a wide range of sources, easy to obtain, and low cost. The used packaging materials and packaging containers should be easy to handle, not pollute the environment, and avoid public nuisance.
6. The proper use of packaging materials is related to the cost and safety performance of product transportation
Packaging products with appropriate packaging materials can save a lot of costs, and lower costs can also make products more secure.
