A "Kraft AL bag" typically refers to a packaging bag that combines Kraft paper (a strong and coarse paper made from wood pulp) with an aluminum foil layer. This combination of materials is often used to create packaging solutions with specific properties, such as moisture resistance, barrier protection, and freshness preservation.
Here are some key characteristics of a Kraft AL bag:
Moisture Resistance: The aluminum foil layer provides excellent resistance against moisture, preventing the penetration of water and maintaining the integrity of the packaged contents.
Barrier Properties: Aluminum foil offers effective barrier properties against gases, light, and other external factors. This helps protect the contents from oxygen, light, and other elements that could degrade the quality of the product.
Strength: Kraft paper contributes structural strength to the bag, making it suitable for packaging various types of products. The combination of Kraft paper and aluminum foil creates a sturdy and reliable packaging solution.
Recyclability: Kraft paper is generally recyclable, contributing to the bag's environmental friendliness and reducing its impact on the environment.
Kraft AL bags are commonly used for packaging products that require high moisture resistance, such as coffee, tea, nuts, and health supplements. The specific features of these bags may vary based on the manufacturer and product specifications. Overall, they provide a versatile and effective solution for preserving the quality and freshness of sensitive products.
