ATTRIBUTE
High barrier back seal pouches are functional flexible packaging solutions that provide exceptional protection against oxygen, moisture, and aroma loss. They are specifically designed for high-value products that demand strict storage conditions and extended shelf life. These pouches are widely used in specialty coffee, fresh meat products, baked goods, pharmaceutical intermediates, and other sectors.
Constructed with multi-layer composite structures, high barrier back seal pouches can be precisely engineered to include EVOH high-barrier layers, nylon puncture-resistant reinforcement layers, and aluminum or metallized light-blocking layers according to product requirements. This combination effectively prevents the ingress of oxygen, moisture, and ultraviolet light, while preserving the product's aroma and protecting active ingredients from oxidative degradation. Under ambient conditions, such packaging can significantly extend product shelf life, while reducing customers' cold chain transportation and storage costs.
The pouch body features a full-length central back seal, eliminating weak points along the edges. The heat seal is uniform and stable, ensuring leak-proof performance. Meanwhile, the front surface remains free of seals, providing a smooth, uninterrupted plane that maximizes branding and marketing opportunities, while maintaining protective performance and shelf display appeal.
CUSTOMIZATION OPTIONS
Our high barrier back seal pouches can be equipped with auxiliary features such as zippers, tear notches, one-way degassing valves, and hanging holes. Barrier levels, dimensions, and composite structures can be customized to meet specific requirements. All pouches comply with relevant industry safety and regulatory standards, offering long-term, reliable protection for high-value products.
