1. What is a 3-layer carton?

3 layers carton is a type of paper carton, made up of 3 layers of cardboard. In it, includes 2 layers of paper on the outside and a layer of sine wave paper in the middle.

2. Features of 3-layer carton

3-layer carton is composed of 3 layers of paper including: surface paper layer, corrugated paper layer and innermost paper layer. Each layer of different paper has different functions, creating a quality carton to meet customer requirements.

2.1. Surface paper layer

This is the outermost layer of the carton, usually white, yellow or brown. Because it is the surface of the box, smooth, flat and standard paper is often used to increase professionalism when packing and transporting products and goods.  

2.2. The middle layer of corrugated paper

This is the layer of paper in between the inner and outer surface layers of the carton. This layer of paper is composed of layers of sine wave paper with various wave patterns such as: 

  • Wave A

Paper wave height: 4.0 – 4.9 mm. Wave frequency: 33 wavelengths per 30cm of paper. Error: 3 wavelengths. 

Carton paper using A wave withstands good dispersion forces on the entire surface of the carton.

  • BOOM

Paper wave height: 2.2 – 3.0 mm. Wave frequency: 47 wavelengths per 30cm of paper. Error: 3 wavelengths. 

Cartons using B wave withstand high penetration force.

  • Wave C

Paper wave height: 3.2 – 4.0 mm. Wave frequency: 39 wavelengths per 30cm of paper. Error: 3 wavelengths. 

Cardboard paper using wave C combines both advantages of both wave A and B. 

  • Wave E

Paper wave height: 1.0 – 1.8 mm. Wave frequency: 90 wavelengths per 30cm of paper. Error: 3 wavelengths. 

This layer of corrugated paper has the role of increasing the dispersion and bearing capacity as well as resisting collisions when packing and transporting goods. 

The 3-layer crate is mainly used for A, C wave layers.
