Product freshness retention is the core demand of European and American consumers and brands for flexible packaging, especially for food, health products and aromatic products. Our custom stand-up pouches adopt professional internal VMPET vacuum aluminum plating technology, which builds an all-round protective barrier and fundamentally extends the shelf life of products, bringing significant market advantages to brand merchants.
Oxygen erosion is the primary cause of product deterioration. Oxidation reaction will lead to fat rancidity of nuts and dried fruits, aroma loss of coffee and tea, and nutritional degradation of health supplements. Traditional single-layer plastic pouches have poor oxygen isolation performance, resulting in short product shelf life and high return rates. The VMPET aluminum-plated layer forms a dense metal isolation layer inside the pouch, which can block more than 99% of oxygen penetration, effectively inhibit aerobic bacterial reproduction and oxidative deterioration, and maintain the original taste and nutrition of products for a long time.
In addition to oxygen isolation, the aluminum-plated structure also achieves excellent moisture and light barrier effects. The humid climate in European coastal areas and the dry and hot climate in North America put forward higher requirements for packaging moisture resistance. VMPET layer can prevent external moisture from penetrating into the pouch, avoid product dampness, agglomeration and mildew. At the same time, it completely isolates ultraviolet and visible light, preventing light-induced product discoloration and ingredient decomposition, which is especially suitable for light-sensitive products such as spices, cosmetics and functional foods.
Different from thick and bulky aluminum foil bags, VMPET vacuum aluminum plating technology realizes ultra-thin and lightweight barrier protection. It does not increase the weight and volume of the packaging, reduces logistics and transportation costs for European and American cross-border sellers, and conforms to the lightweight and low-carbon packaging trend in the Western market. Combined with the tight sealing performance of the inner PE layer, our aluminum-plated stand-up pouches can maintain long-term freshness in sealed state, helping brands reduce product waste and improve customer satisfaction.
