Oxygen barrier performance is measured using the oxygen transmission rate (OTR), which indicates how much oxygen passes through a defined area of packaging film over a specified period. A lower OTR generally indicates stronger oxygen resistance when results are compared under the same testing conditions.

Pet food packaging develops odors when fats oxidize, volatile compounds migrate through packaging materials, or residual substances remain from printing and lamination. Poor seal integrity and unsuitable storage conditions may also allow moisture or oxygen to affect the contents. Identifying whether the smell comes from the food or packaging itself is essential before changing the material structure.

Side gusset pouches increase packaging capacity through expandable folded panels along both sides of the bag. These panels open as the package fills, creating additional internal depth without requiring a proportionally wider front surface. The result is a more efficient three-dimensional storage space for products such as coffee beans, dry foods, powders, and granular materials.

Aluminium pet food packaging prevents oxidation by creating a highly effective barrier against oxygen, moisture, and light. Its continuous metal layer greatly limits gas transmission, slowing reactions that cause fats to become rancid. This protection is particularly important for dry kibble, freeze-dried treats, and pet foods containing oils or animal fats.
