What are the characteristics of metal packaging materials?
1. Excellent mechanical properties and barrier properties, good comprehensive protection performance.
The mechanical strength of metal packaging materials is superior to other packaging materials. Metal packaging boxes, despite their thin walls, have high compressive strength and are not easily damaged. In addition, it is also resistant to high temperature, temperature and humidity changes, insect pests, and erosion of harmful substances.
Metal packaging materials have excellent barrier properties, such as gas barrier properties (such as oxygen, carbon dioxide, water vapor, etc.), moisture resistance, shading properties (especially UV blocking), and fragrance retention properties. Therefore, they are widely used in food, medicine, Packaging of chemical products.
2. Beautiful appearance.
Metal packaging materials have their own unique metallic luster, which is convenient for printing and decoration, making the appearance of the goods gorgeous and beautiful, and improving the sales value of the goods. In addition, various metal foils and metallized films are also very ideal trademark printing materials.
3. Good processing performance. Metal materials have good processing performance and mature technology, which are suitable for continuous automatic production. Metal packaging materials have good ductility and strength, and can be rolled into sheets and foils of various thicknesses. Foil can be compounded with paper, plastic, etc. Metal aluminum, gold, silver, chrome, titanium, etc. are also coated on plastic and paper.
4. Rich in resources and good in waste disposal. Iron and aluminum, which are the main metal packaging materials, are extremely abundant on the earth, and have formed large-scale industrial production with a wide variety of materials. Metal packaging boxes can generally be recycled and recycled to reduce environmental pollution.
