    定制快遞常用紙箱,兩層牛皮卡紙板和一層瓦楞芯紙夾層粘合而成即是三層瓦楞紙箱,由此延伸,一層是牛皮卡紙板,二層是瓦楞紙芯,第三層是牛皮卡紙板,第四層仍舊是瓦楞紙芯,第五層是牛皮卡紙板,這五層粘合成一體,即稱五層瓦楞紙箱。五層紙箱瓦楞紙板是一個多層的粘合體構(gòu)成。瓦楞紙箱有很高的機(jī)械強(qiáng)度,能和摔跌。瓦楞紙箱的實(shí)際表現(xiàn)就取決于瓦楞芯紙和紙板的特性及紙箱本身結(jié)構(gòu)這三項因素。七層瓦楞紙箱即有三層瓦楞紙芯和四層牛皮卡紙板粘合構(gòu)成。瓦楞紙箱海關(guān)出口標(biāo)準(zhǔn):一定印刷 Made in China標(biāo)志。
    Custom express commonly used cartons are composed of two layers of kraft cardboard and one layer of corrugated core paper. This is a three-layer corrugated carton, which extends from this. The first layer is kraft cardboard, the second layer is corrugated core, the third layer is kraft cardboard, the fourth layer is still corrugated core, and the fifth layer is kraft cardboard.

The seven layer corrugated box is composed of three layers of corrugated paper core and four layers of kraft board. Customs export standard for corrugated boxes: made in China logo must be printed.
