Advantages of double gray cardboard for packaging materials
Double-gray paperboard is an environmentally-friendly product that is processed by a series of modern processes using recycled paper,such as newsprint and other waste papers,according to the requirements of green packaging.
The so-called green packaging refers to those packaging that can be reused,recycled or degraded,corrupted,and will not cause pollution to the human body and the environment throughout the life cycle of the product.The indicators of double-gray cardboard are in full compliance with the requirements of green packaging;especially compared with wood packaging,double-gray cardboard has many advantages.
1,stiffness,safety and health
Product packaging,in particular,requires packaging materials to have reliable protection for the product itself.The production process of double-gray paperboard not only satisfies the product's requirements for stiffness,but also has high flatness and is suitable for use in automatic production equipment.The safety and efficiency of the production process will be greatly improved.
At the same time,due to the fact that some wood packaging will carry pests and diseases,combined with international trade restrictions,this will cause irreparable damage to the export of products.In recent years,the ban on wooden pallets in the United States and the European Union has already sounded the alarm for us.The double-gray paperboard has undergone rigorous inspection and treatment in both the raw material and the processing process,so that the cardboard fully meets the hygiene requirements,expands the priority area ofthe packaging of the cardboard,and improves the grade of the packaged product.
2.Protecting the ecological environment
In the production process,the double-gray paperboard is more scientific and environmentally friendly,reducing the use of pollutants,and the raw materials used are recycled fibers such as waste paper,making full use of the value of waste.At the same time,the used waste can also be used for the reproduction of paperboard,and the whole paperboard production process is constructed into a reciprocating and environmentally friendly production chain.
Double gray cardboard can be completely recycled and reused after use.The process of re-use makes the utilization of limited resources greatly improved,and the double-gray paperboard does not need to go through the process of coating the upper layer and the upper coating layer,saving a large amount of expenditure on water and electricity,chemical products,and human resources.The wood packaging not only uses a large amount of material,but also consumes a large amount of natural or artificial forest.In addition,the recovery rate of wood resources is slow,and as a packaging material such as wooden boxes,the role of wood cannot be fully exerted,which has a certain influence on the rationality of the structure of the entire wood.
Not only that,but double-gray cardboard also has a wider range of applications,such as hardcover books,book covers,paper puzzles,data box folders,and substrates for leather goods and bags.This reflects the wide use value and considerable market prospects of double-gray paperboard as a new generation of packaging materials.
