When Pet Food Causes Diarrhea: Could Packaging Be the Problem?
Recently, a pet food manufacturer reached out to us with a concerning issue: several pets developed diarrhea after eating food from the same production batch, while others were completely unaffected. Understandably, this raised alarms about product safety and quality control.
Today, our Production and Operations Director, Mr. Yu, shares key insights into how packaging plays a crucial role in preventing such problems.
The Root Cause: Contamination and Spoilage
Most cases of diarrhea in pets after eating commercial food are linked to contamination or spoilage. This can happen due to several factors — but from a packaging perspective, two areas require strict control:
1. Cleanroom Production of Packaging Film
All our laminated pouches and packaging films are produced in a sealed, temperature- and humidity-controlled cleanroom environment.
Why is this important?
A cleanroom limits exposure to airborne particles, bacteria, and microorganisms
It keeps microbial levels within strict safety thresholds
It ensures that the interior of the packaging remains sterile and uncontaminated
💡 Especially for pet food, even small microbial contamination can cause spoilage or health risks.
2. Preventing Micro Leaks: Pinhole and Puncture Control
Even the best pet food can become unsafe if packaging is damaged.
During packaging and transportation, flexible pouches can develop:
Pinholes
Micro punctures
Seal damage
These flaws allow oxygen or moisture to enter, which may lead to spoilage.
At Sky Utility Pack, we perform:
Leak testing
Seal strength inspection
Multi-stage quality control
…to eliminate these risks before products are shipped.
