What Is a Back Seal Aluminium Foil Pouch? Structure & Advantages
Superior Barrier Protection with a Clean Back-Seam Design
A back seal aluminium foil pouch features a single vertical seal on the back, leaving the front completely smooth for uninterrupted branding and a premium shelf presence. The aluminium foil layer provides the ultimate barrier against oxygen, moisture, and light — making it the go-to choice for products that demand extended freshness and aroma preservation.
Our typical structure: PET Outer Layer → Aluminium Foil Core → PE Inner Sealant. Additional layers like nylon or kraft paper can be integrated for puncture resistance or a natural feel.
Key benefits: 100% light blockage, near-zero oxygen transmission, and excellent moisture barrier — essential for food, pharmaceuticals, and sensitive industrial products.
