What Structure and Types of Kraft Pouch Can Be?
According to their structure and function, kraft paper bags can be mainly classified into the following categories:
Pure kraft paper bags:
Made of single or multiple layers of kraft paper, sealed by sewing or gluing. They have high strength but are not moisture-proof or leak-proof. They are commonly used for packaging flour, sugar, coffee beans (for short-term use), hardware parts, etc.
Kraft paper composite bags:
This is the mainstream form of functional kraft paper bags. By laminating a plastic film on the inner layer of kraft paper, it gives them new properties.
Common structures: Kraft Paper/PE or Kraft Paper/AL/PE.
This structure enables them to be moisture-proof, oil-proof, and heat-sealable, and can be used for packaging food with shelf life requirements, pet food, etc.
Self-standing kraft paper bags:
By combining kraft paper with a moisture-proof heat-seal layer, a bag with a self-standing structure at the bottom is formed. It combines the appearance of kraft paper with the convenience of modern flexible packaging, and is a popular choice for high-end snacks, coffee, and tea.

What Are the Advantages and Challenges of Kraft Pouches?
Advantages:
1. Powerful brand narrative: The natural appearance directly links to concepts such as "sustainability", "health", and "handmade".
2. Deeply rooted environmental image: It is a powerful tool for the brand to showcase its environmental responsibility.
3. High strength and durability: It provides excellent physical protection.
4. High consumer appeal: Many consumers believe that kraft paper packaging is more advanced and responsible than plastic packaging.
Challenge:
1. Poor inherent barrier properties: Pure kraft paper is not moisture-proof, oil-proof, and has poor gas barrier. It needs to be solved through coating or compounding, but this will reduce its environmental friendliness.
2. Printing limitations: It is not suitable for complex patterns that require high precision and full color. The design style is limited by its own color and texture.
3. Cost considerations: The cost of high-quality kraft paper and compounding processes may be higher than that of ordinary plastic packaging.
4. Weighing the environmental impact: Once coated, its recyclability and degradability will be greatly reduced.
