1. What Are Three-Layer Carton Boxes?

Three-layer carton boxes are a type of paper-based packaging constructed from three layers of paper: two flat linerboards on the outer surfaces and one corrugated medium in the middle. This structure provides high durability and excellent load-bearing capacity, making three-layer carton boxes suitable for packaging and protecting goods during transportation and storage.

Low-cost three-layer carton boxes are ideal for packaging lightweight, small-sized products such as instant noodles, cosmetics, pharmaceuticals, tissue paper, etc. These boxes are manufactured using various flute types, including C flute, E flute, B flute, and A flute.

2. Structure of Three-Layer Carton Boxes

✿ Outer Layer:

The outer layer is the outermost surface, made from smooth, flat, and visually appealing paper. Three-layer carton boxes are commonly available in three basic colors: yellow, brown, and white.

✿ Middle Layer:

The middle layer is made from corrugated paper, forming a fluted structure. The corrugated medium is bonded to the inner surface of the outer liner. This layer functions as a cushioning core, providing impact resistance, compression strength, and shock absorption.

✿ Bottom Layer:

The bottom layer is made from standard paper or rigid linerboard. This layer serves as a reinforcement layer, with a paper grammage approximately twice that of the outer liner, enhancing overall structural strength.
