At most, the paper corner protector can bear the pressure of 1500 kg. Therefore, when transporting items such as washing machines, microwave ovens, refrigerators, etc., use some short paper corner protectors on the four corners of the cartons to stack the cartons together without squeezing the contents, so as to avoid unnecessary damage during transportation.

　　纸护角可根据客户的不同规格及要求量身定做的它可以在货物的运输途中起到加固和托盘的作用，从而避免货物在搬运、装箱、运输过程中对边缘的角落的损伤。

　　Paper corner protector can be customized according to different specifications and requirements of customers. It can play a role of reinforcement and pallet in the transportation of goods, so as to avoid damage to the corner of the edge during the transportation, packing and transportation of goods.

　　纸护角的材质是把硬纸板层压胶粘合而成，所以可以回收和再循环。并且在出口集装箱中可以免熏蒸，节省成本，得到广泛运用。

　　The material of the paper corner guard is made of the laminated adhesive of the cardboard, so it can be recycled and recycled. In addition, it can be widely used in export containers without fumigation and cost saving.

　　目前市场上纸护角覆膜用黏合剂产品多为溶剂型聚氨酯黏合剂，鉴于溶剂对人体有害，使用时存在火灾隐患，一些纸护角厂家研发出了对环境无污染、不可燃、、适应性广的水性聚氨酯黏合剂。但其粘合强度于溶剂型、干燥速度慢、能耗及成本较高，发展前景不容乐观。近来，国外又生产出了无溶剂聚氨酯黏合剂产品。无溶剂型纸护角聚氨酯属真正意义上的环保产品，且剥离力强、能耗、适用范围广，因此必将在市场上得到迅速推广。

　　At present, most of the adhesive products used for paper corner protection and lamination are solvent polyurethane adhesive. In view of the harm of solvent to human body and the potential fire hazard in use, some paper corner protection manufacturers have developed water-based polyurethane adhesive which is pollution-free, nonflammable, non-toxic and widely adaptable to the environment. However, its adhesive strength is lower than solvent type, drying speed is slow, energy consumption and cost are high, so its development prospect is not optimistic. Recently, solventless polyurethane adhesive products have been produced abroad. Solventless polyurethane is a kind of environmental protection product in the true sense, which has strong peeling force, low energy consumption and wide application range, so it will be promoted rapidly in the market.

　　随着人们环保观念的日益增强以及纸护角行业竞争日趋激烈，纸制品行业黏合剂出现了较为明显的变化趋势。即绿色环保、成本廉、初粘快、粘合牢固的淀粉黏合剂将在各种纸制品工艺中占据更大的比例，白乳胶的市场份额将进一步缩小，而热熔胶、UV盒粘盒胶及覆膜胶等专用胶水将局限在纸护角专属范围内使用。

　　With the increasing of people's concept of environmental protection and the increasingly fierce competition in the paper corner protection industry, the adhesive in the paper products industry has shown a more obvious trend of change. That is to say, the starch adhesive with green environmental protection, low cost, fast initial adhesion and firm adhesion will occupy a larger proportion in all kinds of paper product processes, the market share of white emulsion will be further reduced, and the special adhesives such as hot-melt adhesive, UV box adhesive and laminating adhesive will be limited to the special scope of paper corner protection.
