First: solid wood packing box
It is a packing box made of solid wood board nails. It has the following advantages: strong and strong, good puncture resistance, simple process, recyclable, and it has been widely used in the transportation and packaging of industrial products. Low price, good security!
Of course, both advantages and disadvantages are complementary to each other. Its disadvantages are:
One is poor sealing. There are gaps between the wooden strips, the sealing is not strict, and linoleum or plastic bags must be used inside in order to prevent rain, and the second is the poor cushioning performance. There is no elasticity, and the shock resistance is extremely poor. The cost is high and the difficulty is high, so the country urgently needs to develop new packaging materials.
Second: plywood box
The plywood box is made of artificial multi-layer plywood and pressed by high temperature and high pressure. It is the first choice for fumigation-free wooden box packaging and can be directly used for export.
Second: plastic board packing box
It is made of plastic molding; its strength is lower than that of solid wood board and higher than that of corrugated paper. The advantages are also obvious that it is easy to clean and reusable. It is especially suitable for beer and beverages and other commodities that need to be recycled for packaging. However, Of course, because it is a plastic product, it is brittle, not easy to regenerate, and has serious pollution, so it has begun to be more and more restricted.
Third: corrugated cardboard boxes
Corrugated cardboard is formed by bonding corrugated cardboard core and face paper. Corrugated cardboard can be divided into single corrugated (three layers), double corrugated (five layers) and multi-corrugated according to the total number of layers of face paper and core paper. The more layers, the thicker the board and the higher the strength. It has the advantages of light weight, certain buffer performance, abundant resources, low price, easy recycling and disposal, smooth surface, easy to print words and trademarks.
However, it also has the disadvantage that it cannot carry too heavy goods. The box board of the corrugated cardboard box is soft inside and outside. The larger the box, the softer it is, so the size of the box is also limited. The bending resistance of corrugated cardboard is different in different directions. The horizontal direction is much better than the vertical direction. The horizontal bending strength is 29 times that of the vertical direction. The corrugated cardboard box on the bottom layer is easy to deform and expand when stacking.
