Aluminum spout pouches, widely used in recent years for packaging food, daily chemicals, beverages, and industrial liquids, directly impact product market access due to their safety and compliance. To meet the stringent regulations for liquid packaging in various countries, aluminum spout pouches must comply with relevant standards in material selection, structural design, manufacturing, and quality testing.
Regarding material safety, aluminum spout pouches must use raw materials that meet food-grade or industry-grade requirements. For food and beverage packaging, they must comply with relevant regulations from the FDA, EU (EU 10/2011), and China's GB 4806 series, ensuring the material is free of harmful substances, heavy metal migration is within safe limits, and it will not release harmful components into the liquid under normal use conditions. For chemical liquid packaging, the material must be corrosion-resistant, swelling-resistant, and immersion-resistant to prevent chemical reactions with the contents.
In terms of structural design, aluminum spout pouches typically employ a multi-layered composite structure, such as PET/AL/NY/PE or PET/NY/AL/CPP, to achieve high barrier properties, puncture resistance, and heat-sealing strength. These structures not only enhance oxygen, moisture, and light protection but also ensure the bag remains undamaged and leak-proof during transportation and storage, meeting various packaging safety requirements. Furthermore, the spout material must match the composite layers of the bag to ensure a secure heat seal, preventing detachment or leakage due to pressure or compression.
During manufacturing, companies must strictly adhere to GMP (Good Manufacturing Practices) and ISO quality control systems to ensure a hygienic, controllable, and stable process. The use of modern equipment such as solvent-free lamination technology, automated printing control, and online quality inspection systems helps reduce solvent residue, printing deviations, and poor sealing, improving product compliance from the source.
Finished products must also undergo a series of tests to meet regulatory requirements, including pressure resistance testing, drop testing, sealing performance testing, migration testing, and high-temperature and cold-resistance testing. These tests ensure that the aluminum spout pouch remains safe and reliable in various usage scenarios, and that product quality is not affected by packaging failure.
To meet safety regulations for liquid packaging, aluminum spout pouches require strict control over the entire process, from materials and structure to manufacturing processes and testing, to ensure product safety and stability and meet market demands for high-quality packaging.
