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.

　　吸水率是評價瓦楞紙箱防水性能的重要技術(shù)指標，吸水率越小，防水性能越好。根據(jù)標準GB/T 13024-2003《箱板》的規(guī)定，箱板正面吸光度≤35g/m2，為一級產(chǎn)品，且≤40g/m2為一級產(chǎn)品。而吸水檢測可按標準GB/T 1540-2002《紙張和紙板吸水測定方法》進行，浸泡時間一般為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.

　　而瓦楞紙箱的防潮、防水性能，主要取決于涂層的質(zhì)量和涂層的厚度及均勻性的控制。根據(jù)包裝防護等級的不同，我公司一般要求防潮瓦楞紙箱涂布量≤3g/m2，防水瓦楞紙箱涂布量≥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.

　　經(jīng)測試，瓦楞紙箱廠家研發(fā)的型瓦楞紙箱防水防水油包覆量≥12g/m2，采用的吸水量測量方法僅為0.2g/m2，遠低于同行業(yè)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.
