In October 2026, global packaging giant Amcor announced a collaboration with Chinese pet brand Sea Fairy and single-dose contract manufacturer Petino to develop card-style single-dose packaging for pet fish oil and liquid nutritional supplements. These blister-like cards, one dose per compartment, tear open and feed directly onto food, are becoming a new direction for pet supplements.

What Is Single-Dose Pet Supplement Packaging?

Traditional pet fish oil comes in a large dropper bottle, where dosing is eyeballed and the oil oxidizes over time. Single-dose packaging pre-portions each serving into an individual sachet or card:

  • **One dose per compartment**, tear and squeeze onto food
  • **Oxidation protection** — every serving is fresh
  • **Portable** — slip a few cards in your pocket on a walk
  • **Precise dosing** — no more guessing

Common categories: pet fish oil, liquid probiotics, taurine liquid, joint nutrition liquid, skin-and-coat liquid.

Key Manufacturing Points

1. Filling Accuracy

Single-dose compartments are typically 2-5ml each:

  • Misrun rate must stay below 0.5%
  • Seal pressure must be consistent across every compartment
  • Filling nozzles must handle different viscosities (fish oil vs. water-based liquid)

2. Packaging Materials

Card-style single-dose usually uses:

  • **Aluminum-plastic laminate** — excellent barrier against light and oxygen
  • **Easy-tear notch** — owners can open with one hand
  • **Card format** — bookmark or card shape for shelf display

3. Formula Stability

Liquid supplements are prone to separation and sedimentation:

  • Fish oil needs antioxidant treatment (VE or nitrogen blanketing)
  • Water-based liquids need emulsification stabilization
  • No oil-water separation within shelf life

MOQ and Cost

Single-dose packaging has high mold and line setup costs:

  • MOQ typically 10,000-50,000 cards (5-10 compartments per card)
  • Sampling costs are higher than bottled because molds are needed
  • Per-compartment cost drops significantly at volume, down to a few cents

How to Choose a Co-Packer

When shopping for a single-dose pet supplement manufacturer:

1. Do they have a **liquid filling line** (not just dry kibble)?

2. Have they done **aluminum-plastic blister or card packaging**?

3. Can they develop **liquid formula stability** (emulsification, antioxidants)?

4. Do they hold export certifications (FDA, customs registration)?
