If the packing wooden box is not properly cared, the discoloration of wood will also occur. So how to prevent wood discoloration? The fundamental path lies in: limiting the occurrence and existence of external causes, revoking or closing the internal discoloration status of wood, and modifying the discoloration composition structure.

For the prevention of biological discoloration, the environmental factors such as temperature, humidity, pH value, oxygen and nutrient composition of suitable microorganisms or organisms are modified or destroyed, such as water spray preservation, plastic sealing and chemical agent disposal.

For the avoidance of photochromism: cut off ultraviolet light, modify the structure of light absorbing components, isolate the distance from oxygen and capture free radicals, destroy the body structure involved in the discoloration, and remove the precursors of discoloration.

For the prevention of enzyme discoloration, reduce the activity of enzyme and isolate oxygen, such as stopping acid-base treatment, adjusting pH value, wood packaging box, retail of wood packaging box, wood packaging box manufacturers modify the properties of protein by boiling and high-frequency heating, use antioxidants to inhibit the activity of PHENOLASE, and store water to isolate oxygen

For the prevention of chemical discoloration such as light discoloration, acid-base discoloration, iron discoloration and enzyme discoloration, the main measures are to block the external causes by coating with paint film, or to eliminate or modify the internal discoloration of wood by solvent soaking and chemical treatment.

There are many practical research and treatment methods to prevent wood discoloration, but few of the existing anti wood discoloration technologies do not retain the effect. Some discoloration (such as blue discoloration) is very fast, which limits the theoretical use with the problems of treatment depth, wood properties, economic interest and so on. The research and development of low toxic or non-toxic, efficient and multi-functional anti tarnishing agent is still the secondary research target to avoid wood tarnishing.

With the progress of China's economic level, the technological content of the packaging industry continues to add Taicang pallets

With the progress of China's economic level and the increasing scientific and technological content of the packaging industry, the domestic packaging industry has a bright future and has gradually become one of the key industries in the domestic national economy. It is estimated that by 2020, China's packaging industry will become a new type of property with high technology content, good economic benefits, low cost, less background pollution and human capital advantages. Packaging industry has great potential and has become a sunrise property.

At present, there are still three major differences in the domestic packaging industry: first, the product structure is not mainstream, there are many simple and original products, and the product upgrading is slow, so that the structure of plastic packaging products is different, and can not adapt to the changes of market demand; second, the scope of packaging enterprises is small, and the degree of wealth convergence is low; third, the number of packaging enterprises is low; Third, the progress of each region is not balanced, the packaging industry in the western region is relatively backward, and the eastern region is relatively prosperous.

Packaging materials continue to metabolize. In addition to the traditional paper plastic, glass and metal packaging, people have begun to look for new materials to make packaging, and biomaterials have begun to enter the market. With the awareness and application of more and more packaging materials, the categories of domestic packaging materials will be more extensive in the future. With the rapid stop of the material industry, there are more and more old packaging materials with high compression resistance, partition, heat sealing and gas resistance, such as microwave oven packaging. But we need to pay attention to the future progress of the packaging industry is not only limited to the development and application of packaging materials, but also in the exquisite processing. In the future, if the packaging industry wants to make continuous progress, it is necessary to fundamentally adjust the industrial structure.
