Superior characteristics of corrugated paper corrugated board

The main component of corrugated paperboard is paperboard, which is lightweight, strong and can withstand greater wear and impact. Compared to traditional wood or metal materials, corrugated paperboard is one-fifth lighter and has the strength of some metal materials.

The weather is humid, corrugated boxes how to waterproof moisture? These measures should not be ignored

Selection of waterproof corrugated board: In the production process of corrugated board, waterproofing agents can be added to improve its waterproof performance. These waterproofing agents usually include urea-formaldehyde resins, melamine formaldehyde resins, polyvinyl butyral and other polymers. Choose containerboard that has been heavily sized to ensure that water droplets do not penetrate the surface for 5 minutes.

Moisture resistance of paper and paperboard

Raw paper and corrugated paper, especially corrugated paper, have significant water absorption. When the paper is exposed to a humid environment for a long period of time, its water content increases, which in turn leads to a significant reduction in the paper's transverse ring compression strength. At a relative humidity of 85%, the ring compression strength may even drop by 60%.

The Growth of High Strength Corrugated Board

High-strength corrugated cardboard began at the end of the 18th century, the early 19th century because of its lightweight and inexpensive, versatile, easy to produce, and can be recycled and even reused, so that its application has grown significantly.

High-strength corrugated board applications

High-strength corrugated paper is a paper with excellent physical properties and a wide variety of uses. The following is a detailed description of the many uses of high-strength corrugated paper.

Application of Slitter Kraft Paper in Logistics Industry

Slitter kraft paper is widely used in the logistics industry for packaging protection of items due to its strong and durable, tear-resistant, moisture-proof and other characteristics. Whether it is bulk goods or small items, kraft paper can provide effective protection to avoid damage during transportation. Its recyclable, biodegradable properties are also in line with the current concept of environmental protection, and gradually replace some of the disposable plastic packaging materials.
