In order to improve the scientific and technological level of the packaging industry, all countries in the world have adopted high-tech means to research and develop new packaging materials. Various novel materials have emerged as the times require. Recently, a new type of epoxy "wood" has been developed in the foreign packaging industry.
Canada has developed a special packaging structure wood with similar hardness to steel. This kind of wood is made by treating the wood fibers with a special process to make the fibers cross each other, then covering them with epoxy resin on the surface of the wood and then processing them with microwaves. This new type of wood is not deformed, cracked, or stretched. It is used in a wide range of applications in addition to packaging products.
Japan has developed a kind of cast wood, which is called liquid chemical wood. It is understood that it is molded by wood residue, epoxy resin and polyurethane. According to the requirements of the packaging, it can be fixed and shaped without elaborate processing. Its wood grain and gloss are similar to those of natural wood, but its cost is much lower than that of natural wood.
Many people eat and sleep a little in winter and hate dark mornings and short days. This is called "winter blue". Others have more serious symptoms such as sleep disorders, withdrawal symptoms, binge eating, depression, anxiety, and lethargy. These often lead to family, work, and relationship difficulties. This is a perceived problem called seasonal affective disorder (SAD).
SAD is caused by a lack of bright light in winter. The light that enters our eyes stimulates our brain and controls our daily rhythm through the production of hormones. For some people, winter does not have enough light to regulate the hormones that prevent us from getting up and sleeping, being energized, and depressed.
