產(chǎn)品介紹：

瓦楞紙板是一個多層的黏合體，它少由一層波浪形芯紙夾層（俗稱“坑張”、“瓦楞紙”、“瓦楞芯紙”、“瓦楞紙芯”、“瓦楞原紙”）及一層紙板（又稱“箱板紙”、“箱紙板”）構(gòu)成。它有很高的機械強度，能抵受搬運過程中的碰撞和摔跌。瓦楞紙箱的實際表現(xiàn)取決于三項因素：芯紙和紙板的特性及紙箱本身的結(jié)構(gòu)。
又稱波紋紙板。由至少一層瓦楞紙和一層箱板紙（也叫箱紙板）粘合而成，具有較好的彈性和延伸性。主要用于制造紙箱、紙箱的夾心以及易碎商品的其他包裝材料。

瓦楞紙可以依據(jù)哪些標準進行檢測

GB/T 6544-2008 瓦楞紙板

GB/T 6543-2008運輸包裝用單瓦楞紙箱和雙瓦楞紙箱

GB/T 13023-2008 瓦楞芯(原)紙

Corrugated Cardboard Introduction

Corrugated cardboard is a multi-layered adhesive body, which consists of at least one layer of corrugated core paper (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and one layer Cardboard (also known as "carton board", "carton board"). It has high mechanical strength and can withstand collisions and falls during handling. The actual performance of the corrugated carton depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

Also called corrugated cardboard. It is composed of at least one layer of corrugated paper and a layer of boxboard paper (also called boxboard), which has good elasticity and extensibility. It is mainly used to manufacture cartons, carton sandwiches and other packaging materials for fragile goods.

Corrugated paper can be tested according to which standards

GB / T 6544-2008 Corrugated cardboard GB / T 6543-2008 Single and double corrugated cardboard boxes for transport packaging GB / T 13023-2008 Corrugated core (original) paper
