Nowadays people pay more attention to environmental protection issues, and all walks of life have obvious manifestations. For example, there are new environmentally-friendly packaging materials in the packaging industry. I don’t know what people know about this packaging material. What are the characteristics of this new packaging material? It is non-toxic and harmless to the human body and can be recycled. With these questions, I will introduce you to several common new packaging materials.
Polylactic acid
The new polyester material produced from organic acid lactic acid is better than the existing plastic polyethylene, polypropylene, polystyrene and other materials. It is defined by the industry as a new packaging material with a promising future in the new century. It is an environmentally friendly packaging material. A star, in the future, is expected to replace polyethylene, polypropylene, polystyrene and other materials for plastic products, and has broad application prospects.
2. Resin-based composites
A variety of polymer composites that are compounded with various fibers, granules, or films based on a resin. For example, the addition of conductive fibers into conductive functional materials, absorbing functional materials, ceramics, glass fiber and carbon fiber composite reinforcing materials, or multilayering of different resin films into composite materials, etc., has a wide range of applications;
3. Metal matrix composites
It has high strength, high modulus, good high temperature performance, good electrical and thermal conductivity, and is suitable for aviation and other industrial sectors. Metal-based composite technology has advanced rapidly and has a variety of methods. Therefore, the metals used for the composite are mainly Ti, Ni, Cu, Pb, and Ag, and are light metal-based Al, Mg, Ti, and the like. Composite materials are metals, non-metals and other compounds.
4. Biopolymer materials
Biopolymer materials have entered experimental stages such as artificial blood vessels, artificial hearts, artificial valves, artificial lungs, artificial tendons, artificial bones, and the like. The application of biopolymer materials in packaging is expanding. For example, microbial (bacterial) plastics, biodegradable plastics, and glazing plastics are hot topics in today's packaging.
5. Silicone and fluorine-based materials
6. Silicon-based polymer materials are new materials in the 21st century. At present, on the basis of molecular design and molecular structure control, the synthesis reactions such as defluorination condensation and hydrosilane methylation are discussed, and molecular diversified functional materials are developed to develop optoelectronic functional materials for high-grade composite filming equipment.
7. Metal foils and profiles Due to the development of thinning technology, the types of metal foils have increased greatly. The main varieties are gold foil, copper foil, aluminum foil, Be foil, Ta foil, Ag foil, Zn foil, iron foil, and Ni. - CR and other alloy foils.
What are the new packaging materials? What are the characteristics of each? The above content gives a detailed introduction to these two issues. If you are interested in this aspect, you need to know more about it, you can pay attention to our printing and packaging network.
