The traditional adhesive contains free TDI, so the traditional adhesive has the defects of hidden pollution hazards such as solvent residue, flammability, explosiveness, VOC emission and the like, and is replaced by the environment-friendly adhesive which has good quality and no pollution and meets international standards with the improvement of health consciousness of people due to the fact that environmental regulations in China are gradually perfected. The environment-friendly adhesive is an adhesive without organic solvent or with low content of organic solvent, is friendly to consumers and processors, is environment-friendly and resource-friendly, and meets the three requirements of environmental protection, health and safety.
Corrugated cardboard boxes are made of corrugated cardboard and are the most widely used paper packaging containers. It can be said to be a preferred packaging method. The paperboard structure is 60-70% hollow and has excellent cushioning and shock absorption properties. The thickness of the shingle is twice as great and is greatly enhanced compared to the same basis weight laminated paperboard. The transverse compressive strength of paperboard is used in many applications for shipping packaging. Let us look at the corrugated carton tray that leads the packaging market in china. Corrugated containers such as wooden boxes and the like are gradually replaced by the corrugated containers with excellent performance and good processability for more than half a century, and the corrugated containers become the main force of transportation and packaging. In addition to protecting the merchandise and facilitating storage and transportation, it also serves to beautify the merchandise and promote the merchandise. The tile carton is a green product, is beneficial to environmental protection and is convenient to load, unload and transport. But the moisture resistance of the corrugated case is poor, and the corrugated case can be softened and the paper quality is poor by humid air or long-term rainy days; and the corrugated case is stacked for a long time, and the shock resistance is reduced.
