4L Freezer-Safe Aluminium Spout Pouch for Calf Colostrum Feeding

Designed for calf colostrum feeding and chilled liquid delivery, this pouch is built with a four-side-seal or three-side-seal construction and widened heat-sealed edges for drop and compression resistance. A welded spout sits on top and can be fitted with a screw cap or one-way valve, giving steady flow with minimal backflow. A bottom gusset or hanging hole is optional for suspension feeding and fast emptying, and the seal holds up well after freezing at 4L capacity.

The laminate can be specified as PET/AL/PE, PET/NY/PE or other food-grade combinations, with a food-grade PE inner sealing layer that blocks oxygen and light for frozen and chilled storage. Outer surfaces accept 1-8 colour gravure printing, reproducing brand colours, farm logos and usage instructions with strong ink adhesion and fade resistance. Standard volumes run from 100ml to 5L, while spout diameter, bag dimensions and roll width stay adjustable, and matching roll film is available.

Typical uses include calf colostrum feeding, ranch liquid nutrition, chilled dairy distribution and liquid pet food portions. The custom process is straightforward: send samples or artwork, confirm bag type, material and print layout, then move to sampling and bulk production. Our factory in Dongguan, Guangdong runs a Class 10,000 clean room and handles film blowing, lamination and bag making in house, with an MOQ of 10,000 pcs for export orders, and packing can be arranged to suit destination requirements.
