Basic knowledge of carton processing factories

　　1、Box class

　　Carton packaging products are widely used, according to different materials, single layer corrugated cartons, cardboard boxes and other boxes, commonly used three layers, five layers, seven layers, according to the number of cartons to determine the size of the joint, three case 75px joint, five layer joint box general 100px.

　　2、Carton structure

　　Each layer is divided into paper, corrugated paper, paper, paper, paper, tea board paper, kraft paper, and core corrugated cardboard box. The three layer also called single corrugated cardboard box is made of cardboard boxes on both sides to form a layer of corrugated paper. Five corrugated boxes, also known as double corrugated boxes, for short, three yellow and two watts. The five layer corrugated cardboard structure consists of two parts: paper, paper, core paper and corrugated paper.

　　According to our company's packaging, the three layer of paper is made of A, and the five layer is made of BC.

　　Three layers of paper: made of tissue paper, corrugated core paper and inner paper.

　　Five layers of paper: paper + corrugated core paper + paper + corrugated core paper + inner paper five layers.

　　3、The material used in a carton factory

　　Classification of materials: cardboard material is classified according to the weight per unit area, mainly with several cardboard materials: K paper: 250g/m - 175g / M B paper: paper: degree M 7 M 8 200g/ paper: paper: 260g / M C - 127g / rice paper: paper: cardboard + 115 grams / meters - three layers, five commonly used The layer and the seven layer are less used. Each layer is divided into paper, corrugated paper, paper, paper, paper, tea paper, kraft paper and corrugated paper. The color and texture of the paper are different. The paper (color and feel) produced by different manufacturers is different, and the national standard GB6543 - 86 "corrugated box corrugating wave X".

　　4、Corrugated paper of carton processing plant

　　Corrugated cardboard corrugated type, according to the high class A, B, C, E four kinds, different corrugated cardboard's mechanical properties are also different.

　　Plane pressure: corrugated board has high plane pressure, high compressive strength, B type is the opposite, C type plane pressure, vertical pressure, parallel pressure and buffer force are better;

　　The corrugated cardboard thickness of the carton processing plant: the thickness is A, C, B, E low. Because the thickness of the cardboard is small, it is easy to bend. Therefore, B is widely used in the transportation requirements of corrugated box compression strength packing box.
