New applications of wood plastic composite materials (WPC, also known as plastic wood composite materials) in the packaging field

Plastic wood materials have a wide range of raw materials, simple processing techniques, and can be recycled after use. They are truly in line with national environmental protection policies as a new type of green building material product, perfectly fitting the concept of green building. After modification, plastic wood composite materials have been widely used in multiple fields due to their good dimensional stability, mechanical strength, and corrosion resistance. This article focuses on the application in the packaging field.

WPC box
Packaging boxes are mainly used for transportation, loading and unloading, and storage. Generally, wooden boxes and corrugated boxes are used. However, with the increasing demand for packaging boxes, plastic wooden boxes have gradually developed. A new type of high-performance plastic wood material packaging box with a new structure is designed and manufactured based on comprehensive performance requirements, using functional and composite plastic wood structural materials as the material, with the aim of economic practicality, and according to this concept, as a new generation of integrated packaging equipment. Capable of adapting to various harsh environments with multiple performance requirements; And it is easy to use and recycle, with significant universality and reusability.

The method of preparing P34HB/wood powder biodegradable packaging material by blending hot pressing is to reinforce the biodegradable polymer material P34HB with biodegradable Populus tomentosa wood powder fibers, in order to prepare a biodegradable composite material that can replace traditional non completely degradable plastic wood composite materials. This achieves the concept of green environmental protection in packaging transfer equipment such as pallets and transfer boxes.

Plastic wooden frame
Similar to pallets, plastic wood frames are important tools for goods storage. Plastic wood frames have the performance advantages of wood and plastic, which make up for the performance defects of single materials. They have the following advantages: moisture resistance, high dimensional stability, high hardness, good processing performance, and low maintenance costs. A new type of plastic wood multi-layer frame structure includes a plastic wood frame body and a plastic wood board. The plastic wood board is installed inside the plastic wood frame board, and a stretching table is also installed inside the plastic wood frame body. The stretching table includes a foot board and a support board, and a mutually matched rotating shaft part is installed between the foot board and the support board. The rotating shaft part is equipped with through-holes, which are connected through the installation shaft body. The left and right sides of the foot board are equipped with inserts, and the plastic wood frame body is There are slots on both sides for inserting inserts, and the footrest is inserted into the slots through the inserts. This utility model is convenient to use, easy to operate, and improves the functionality and practicality of the plastic wood frame.

In recent years, the application of film in packaging systems has developed rapidly and is a good alternative to traditional packaging film. The addition of polymers and biodegradable agents to composite materials has aroused great interest, as they can completely degrade under UV radiation and in soil without releasing any toxic or harmful components. Biodegradability of polyvinyl alcohol (PVA)/nano resin facial mask composed of nano silica manufactured by pressing process. The experimental results show that the pressed transient film has good biodegradability (weight loss) under UV irradiation and buried in soil, and can also be used as a food packaging bag, with excellent environmentally friendly performance.

With the rapid development of science and technology, utilizing abundant natural plant fibers to enhance plastics is an important research direction for the sustained growth of polymer based composites. Therefore, plastic wood composites, as a new type of composite material with friendly characteristics such as low-carbon, green, environmental protection, and sustainable development, have attracted great attention. Although most applications in the packaging field are now focused on packaging and transportation, with the continuous optimization of the preparation process and modification methods of plastic wood composite materials, wood plastic composite materials are bound to have a wider range of applications in the packaging field.
