Characteristics Of High Barrier Aluminum Foil Flat Bottom Bags

high barrier performance
Oxygen barrier: The dense structure of the aluminum foil layer completely blocks oxygen, preventing oxidation, rancidity, and spoilage of the contents, thereby extending the shelf life.
Moisture Barrier: Effectively blocks water vapor to prevent products from becoming damp, clumping, losing crispiness, or moisture loss.
Lightproof: Non-transparent, blocking light (especially ultraviolet rays) to prevent oil rancidity, pigment fading, and nutrient loss.
Odor Blocking: Prevents external odors from penetrating while preserving internal fragrance, maintaining the product's flavor.
Strong mechanical properties
High resistance to puncture, tearing, and blast, capable of withstanding compression and friction during transportation and storage, reducing the risk of damage to vulnerable components.
Wide temperature range
It can withstand high temperatures up to 121°C, suitable for processes such as high-temperature sterilization and boiling; it is resistant to low temperatures down to -50°C, ideal for frozen storage, with stable performance.
Excellent heat-sealing performance
The inner heat-sealing layer (such as PE or CPP) can melt and bond at low temperatures, forming a strong and tight heat-sealed edge to ensure sealing, making it suitable for industrial automated packaging.
safety and hygiene
Made with food-grade materials and composite processes, it is non-toxic and odorless, complying with hygiene standards for food contact materials and free from risks of harmful substance migration.
Appearance and Practicality
The surface exhibits strong metallic texture, excellent printing effects, and vibrant colors, enhancing the product's premium quality. The flat-bottom design ensures stability, facilitates stacking for storage, and saves space.
