Custom 4L Large-Capacity Aluminium Foil Spout Pouch for Calf Colostrum Frozen Storage

For dairy farms and milk processing settings, this large stand-up pouch starts with strong seals in a four-side or three-side format, with optional rounded corners to reduce breakage during transport and freezing. A food-grade spout sits at the top and can be specified with a screw cap, one-way valve, or standard flip-top. After filling and sealing, it provides reliable closure for easy pouring and sampling. Hanging holes and handle options can be added for centralized farm hanging, cold-chain stacking, or portioned liquid feed use.

The pouch body commonly uses a PET/AL/PA/PE multilayer aluminium foil laminate. Its aluminium layer blocks light, oxygen, and moisture, which makes it suitable for low-temperature frozen storage of fresh milk and colostrum. The inner layer is a food-grade heat-seal material with low-temperature resistance and puncture resistance. Printing uses 1-8 colour gravure, producing solid colours and clear detail for brand marks, instructions, and volume scales. Standard capacities range from 1L to 5L; bag dimensions and spout diameter can be adjusted on request, and matching roll film in the same material is available.

Applications include freezing calf colostrum on farms, portioning milk at dairy plants, and packaging liquid feed and nutritional liquids. The custom process is straightforward: provide a sample pouch or artwork, and we confirm material structure, size, and print file before arranging a proof. Once the sample is approved, bulk production can begin. Our company is based in Dongguan, Guangdong, with a Class 10000 clean workshop. Film blowing, printing, and bag making are handled in-house.
