    In today's commercial economy, the quality of the product itself plays a vital role, but the quality of its packaging materials can not be ignored! A beautifully packaged shell with excellent quality plays a decisive role in both the selling of the product and the quality assurance of the product itself! In today's outer packaging materials, corrugated paper cartons are generally used to occupy more. How is the definition of corrugated cardboard in the end, and how is the classification and classification of corrugated paper classified? Below, explain for you one by one!

    History dating back to corrugated single-sided corrugated board W in 1871, by the American engineer Ebert Jones (Athert L. Jones) invention, when used as a cushioning material wrapped fragile glass, ceramics. Later, after the improvement of Oliver Long, a double-faced corrugated cardboard similar to that commonly used today is formed. Corrugated paperboard has good elasticity, strength and stiffness. Compared with traditional wooden boxes and metal barrels, the goods it uses to make cartons and carton packs show many advantages. Therefore, it is more and more widely used. At present, in the countries where paper products are well-packaged, the proportion of corrugated board accounts for almost 1/3 to l/4 of the entire packaging material.

    First, the definition

    1. Corrugated paper refers to the formation of regular and permanent paper after the corrugated paper has been processed.

    2. Corrugated cardboard refers to a kind of composite paperboard that is used to manufacture corrugated cartons by bonding one or more layers of corrugated paper between several layers of paper or cardboard.

    3. The minimum comprehensive ration of corrugated board refers to the sum of the quantification of each layer of corrugated cardboard other than corrugated board.

    Second, the type of corrugated board

    ( a ) According to the classification of the corrugated tooth profile

    1 . V -type corrugated 2 . U type corrugated 3 . UV type corrugated

    ( b ) Classification according to tile type

    1 . A type corrugated 2 . B type corrugated 3 . C type corrugated 4 . E type corrugated

    (c ) Classification according to the number of layers

    1 . Single-sided corrugated cardboard

    2 . Single-sided double-sided corrugated cardboard

    3 . Two-ply double-sided ( five-layer ) corrugated cardboard

   4 . Three-sided double-sided ( seven-layer ) corrugated cardboard

    ( D ) China's classification regulations for corrugated cardboard

   GB/T6544 - 2008 "Corrugated board" standard requirements: divided into single corrugated cardboard ( three corrugated cardboard ) , double corrugated cardboard ( five corrugated cardboard ) , three corrugated cardboard ( seven-layer corrugated cardboard ) three categories. According to the minimum comprehensive quantification of corrugated cardboard, single and double corrugated cardboard are divided into 5 categories, and three corrugated cardboard is divided into 4 categories; each category is based on burst strength or side pressure strength ( Corrugated paper, cardboard and adhesive The main raw material for corrugated board production, their quality determines the strength of corrugated board ) is divided into excellent products and qualified products, a total of 28 kinds of corrugated board.
