The products packed in cartons are the most widely used. According to different materials, single-layer corrugated boxes, cardboard boxes and other boxes are commonly used. Joints, five-layer joint boxes are generally 100px.
Each layer is divided into paper, corrugated paper, paper, paper, paper, teaboard paper, kraft paper, and corrugated box with core. Five corrugated boxes, also known as double corrugated boxes, are referred to as three yellow and two tiles for short. The cardboard structure of the five-layer corrugated box is composed of thin paper, inner paper, core paper and corrugated paper.
Three-layer paper: made of face paper, corrugated core paper and inner paper.
Five-layer paper: paper + corrugated core paper + paper + corrugated core paper + inner paper
3. Corrugated paper
Corrugated board corrugated models are divided into four types: A, B, C, and E according to the height of the corrugated board. Different corrugated boards have different mechanical properties.
Plane pressure: A-type corrugated cardboard has the highest plane pressure and higher compressive strength, while B-type is the opposite. C-type has good plane pressure, vertical pressure, parallel pressure and cushioning force.
Thickness: The thickness of corrugated cardboard is the largest for type A, followed by type C, again for type B, and the smallest for type E. Due to the ease of bending of small thickness cardboard, B-shaped corrugated paper is widely used for pressure resistance to boxes Packing and shipping boxes with low strength requirements.
