Made of paper and wood new packaging materials

The College of Resources and Environment of China Agriculture University has recently successfully developed a composite sheet of a new type of corrugated cardboard and multilayer paper core. According to research expert Jin Shi introduced, this kind of corrugated cardboard has high compressive strength and good cushioning performance. It can replace pure wood packaging materials as heavy product packaging boxes. Its packaging costs are 30% lower than wooden boxes and 65% more than wood products. It is estimated that one ton of corrugated board can replace approximately 15 to 20 cubic meters of wood. The newly developed multi-layer paper core composite board with strong bending resistance has special characteristics such as flame retardant, water resistance, light weight, heat preservation, and sound insulation.
Both of these two national patent products use waste paper as the main raw material, which is convenient to process, low in production cost, non-polluting in the production process, and can also be recycled in waste products, with environmental protection and price advantages.
