Bovine Colostrum Bags from IMPAK

IMPAK is proud to announce our newest SpoutPAK™ designed exclusively for liquid colostrum applications.

Our one-gallon (4 liter) colostrum bags come in two fill styles: fill through spout, and fill through top. The fill through spout style is sealed on all four sides and closed with the cap, whereas the fill through top style has a 3.5” opening at the top through which you can fill, and then heat-seal.

The pouches can be pasteurized and frozen to prevent spoilage. They may also be safely reheated in a boiling bath. Read about the physical properties of these SpoutPAKs below.

Both transparent bags measure 11.125" X 12" with a 5.75" bottom gusset. A handle is die-cut into the corner of the pouch for carrying and/or placing on a hook between feedings.

The colostrum spout bags are 6.5 mils thick with a laminated layer of Nylon to prevent punctures and or bursting in the event of a drop. These pouches offer convenience and sanitary colostrum storage.

We are confident these are the quality colostrum storage solution that the calf and foal industry needs.
