瓦楞纸箱的抗压强度，抗压强度又有多高，它是纸箱，怕水就怕潮。瓦楞纸箱防水性能尤为重要，也是围绕的主题。
瓦楞纸箱厂家为大家讲解防水瓦楞纸箱的性能要求。
Corrugated box compressive strength, compressive strength and how high, it is a box, afraid of water, afraid of moisture. Corrugated box waterproof performance is particularly important, but also around the theme. Corrugated box manufacturers to explain the performance requirements of waterproof corrugated box.
吸水率是评价瓦楞纸箱防水性能的重要技术指标，吸水率越小，防水性能越好。根据标准GB/T 13024-2003《箱板》的规定，箱板正面吸光度≤35g/m2，为一级产品，且≤40g/m2为一级产品。而吸水检测可按标准GB/T 1540-2002《纸张和纸板吸水测定方法》进行，浸泡时间一般为2min。
Water absorption is an important technical index to evaluate the waterproof performance of corrugated box. The smaller the water absorption, the better the waterproof performance. According to the national standard GB / T 13024-2003 "box board", the front absorbance of box board is ≤ 35g / m2, which is a class I product, and ≤ 40g / m2 is a class I product. However, the water absorption test can be carried out according to the national standard GB / T 154-2002 paper and board water absorption test method, and the soaking time is generally 2 minutes.
而瓦楞纸箱的防潮、防水性能，主要取决于涂层的质量和涂层的厚度及均匀性的控制。根据包装防护等级的不同，我公司一般要求防潮瓦楞纸箱涂布量≤3g/m2，防水瓦楞纸箱涂布量≥15g/m2。
The moisture-proof and water-proof performance of corrugated box mainly depends on the quality of coating, the thickness and uniformity of coating. According to the different degrees of packaging protection, our company generally requires the coating amount of moisture-proof corrugated box ≤ 3G / m2, and the coating amount of waterproof corrugated box ≥ 15g / m2.
经测试，瓦楞纸箱厂家研发的型瓦楞纸箱防水防水油包覆量≥12g/m2，采用的吸水量测量方法仅为0.2g/m2，远低于同行业的10g/m2的吸水量，具有很好的防水效果。
After testing, the water-proof and waterproof oil coating amount of the environmental friendly corrugated box developed by the corrugated box manufacturer is ≥ 12g / m2, and the water absorption measurement method used is only 0.2g/m2, far lower than the water absorption amount of 10G / m2 in the same industry, which has a good waterproof effect.
