With the enhancement of people’s awareness of environmental protection, more and more attention has been paid to the research and development of environmentally-friendly packaging materials. Paper-based wood and paper-based plastics are among these. Corrugated cardboard is the most commonly used paper packaging material in the market, and corrugated paperboard plays a very important role in packaging materials. In addition to its light weight, low price, easy mechanized production, and recyclability, it also has good flexural rigidity and excellent mechanical properties, and it occupies a large proportion in the field of packaging materials. In order to make better use of corrugated board, people have conducted intensive research and development on its various properties and new components. In the large-scale packaging of cabinet-type air conditioners, refrigerators, and color TV sets, the use of a new environmentally-friendly packaging material, "Watakawa," can effectively achieve the effect of green packaging. "Wazhongwa" is an excellent structure with corrugated paperboard and paper tubes between two layers of plain corrugated paperboard (two-layer, three-layer, five-layer, and seven-layer). Strength of. Compared with ordinary corrugated board, many physical indicators have exceeded several times or even more than ten times. At the same time, the compressive and shock-proof performance is close to that of the wood board, and the cushioning performance is better than that of the wood board. "Wazhongwa" due to its structural features, makes full use of the mechanics of multi-directional support, uses high-strength corrugated paperboard, is arranged by unique process deformation, and is integrated with the best mechanical structure. The six faces form a powerful matrix of pipe piles, which can effectively prevent damage to the contents of the box. Especially for larger, lighter weight, more fragile, and less afraid of pressure products, it can better reflect its superiority. Because "Watakawa" is a full-paper packaging material, it also retains the advantages of good corrugated board resistance, easy fabrication, printability, light weight, good cushioning performance, recyclability, etc. It can also be adjusted by adjusting the thickness of the sandwich layer. The geometry of the sandwich layer adjusts the strength and elasticity (buffering performance) of the corrugated board, and can effectively replace the wood material and the EPS cushioning material. The biggest feature of the "Wa Zhong Wa" made of packing box is to use the "Wa Zhong Wa" paperboard sandwich as the corrugated space, and use the plug (the wood material for the wood, bamboo, plastic or paper tube) to connect with the bottomless box. , It is more convenient for the packing and picking process of heavy items. At the same time, the use of "Watakawa" cardboard due to its good flat pressure and bending strength, if it is connected with the paper tube made of leg brackets, it is convenient for mechanized handling operations. "Wazhongwa" packing box is compact, seamless, nail-free, foldable and easy to mold, not only reduces the overall packaging cost, but also improves the aesthetics and integrity of the packaging box. It will be a relatively large-scale household appliances, electromechanical equipment, etc. Ideal packaging container. A picture frame is a protective and decorative edging for a picture, such as a painting or photograph. It makes displaying the work safer and easier and both sets the picture apart from its surroundings and aesthetically integrates it with them.

A picture frame is a container that borders the perimeter of a picture, and is used for the protection, display, and visual appreciation of objects and imagery such as photographs, canvas paintings, drawings and prints, posters, mirrors, shadow box memorabilia, and textiles.
Traditionally picture frames have been made of wood, and it remains very popular because wood frames can provide strength, be shaped in a broad range of profiles, and allow a variety of surface treatments. Other materials include metals, e.g. silver, bronze, aluminum, and stiff plastics such as polystyrene.
A frame surface may be of any color or texture. Both genuine gilding and imitation gold remain popular, although many other surfaces are to be found in most framing establishments. Some picture frames have elaborate moldings, which may refer to the subject matter. Intricate decorations are often made of molded, then gilded plaster over a wood base.
Picture frame mouldings come in a wide variety of profiles, generally in some sort of L shape with an upward "lip" and a horizontal rabbet. The rabbet functions as a shelf to hold the frame glazing (if any is to be used), some sort of spacer or mat/matte to keep the object safely behind the inner surface of the glazing, the object itself, and backing boards to protect the object from physical damage and environmental pollutants. The lip extends a proportionate distance up from the edge of the rabbet. It restrains materials in the frame and can be used to help set off or reveal the picture aesthetically.
