Unpacking Cardboard Materials – Differences and Selection

The quality and functionality of a cardboard box largely depend on its materials. This article introduces the characteristics and uses of corrugated paper, kraft paper, and other common cardboard materials in detail.

  1. Corrugated Paper: High Strength and Compression Resistance Corrugated paper is the most commonly used material for cardboard boxes. It consists of three layers—linerboard, medium, and fluted paper—providing excellent cushioning and compression resistance. Corrugated paper comes in single, double, and triple-wall structures, with varying thicknesses and strengths, making it ideal for transporting and protecting heavy items.
  2. Kraft Paper: Eco-Friendly and Durable Kraft paper is strong, tear-resistant, and puncture-proof, making it suitable for reuse. Its thinner structure is ideal for light packaging and eco-friendly wrapping, widely used in the food and apparel industries.
  3. High-Density Fiber Paper: Moisture-Resistant and Waterproof This material is commonly used in boxes that require moisture or water resistance, such as those for cold chain logistics. High-density fiber paper undergoes special treatment for moisture resistance, making it an ideal choice for fragile goods and perishable foods.
