4 Layers

Inner Layers 1st and 2nd Layers)
Brown Kraft Paper: Used in the inner parts of the bag, brown kraft paper is known for its strength and eco-friendly nature. These layers protect the material against external factors and enhance durability. They also contribute to the safe transportation of the product.

2. Middle Layer
HDPE (High-Density Polyethylene): The middle layer contains HDPE, which serves as an additional barrier against moisture and other external elements. This layer increases the bag’s impermeability and prevents the contents from being affected by outside factors. It also ensures that the bag is sturdier and more durable.

3. Outer Layer
White Kraft Paper or Brown Kraft Paper: The outer surface of the bag can be made of either white or brown kraft paper, depending on preference. This layer enhances the appearance of the bag while also providing additional durability. White kraft paper offers a cleaner look, while brown kraft paper creates an eco-friendly image.

These four layers make the kraft bag suitable for securely transporting and storing a variety of industrial products, especially sensitive materials such as cement, construction chemicals, seeds, and food products. Each layer is specially designed to enhance the bag's performance and to protect the contents inside.
