Question: What are Kraft Paper Aluminum Foil Bags, and why use aluminum foil as an inner layer?
Kraft Paper Aluminum Foil Bags are a hybrid packaging solution combining kraft paper’s durability with aluminum foil’s barrier properties. These bags offer superior protection for sensitive products such as food, chemicals, and pharmaceuticals. The aluminum foil layer serves as an excellent barrier against moisture, oxygen, light, and odors, ensuring the contents’ freshness and integrity.
Key Features of Aluminum Foil in Packaging:
- Moisture Resistance: Aluminum foil acts as an impermeable barrier to moisture, preserving product quality.
- Oxygen Barrier: It prevents oxidation, extending shelf life.
- Thermal Stability: Aluminum foil withstands temperature fluctuations without degrading.
- Light Protection: Blocks harmful UV rays, preventing spoilage.
- Odor Retention: Locks in odors, maintaining product authenticity.
