Types of Corrugated Paper
Corrugated paper comes in two main types: 3-layer corrugated paper and 2-layer corrugated rolls. These products are widely used in modern packaging, primarily for storing and protecting goods before shipment. Corrugated paper is highly popular due to its numerous advantages, including strength, durability, lightweight properties, and eco-friendliness. Additionally, corrugated paper is categorized into different grades, each designed for specific packaging needs, allowing for a wide range of product applications. Let’s explore the different grades and types of corrugated paper.
