Everything You Need to Know About Vacuum Decay
Is your packaging truly leak-proof? Vacuum decay testing is the gold-standard method for uncovering hidden leaks, ensuring your products stay fresh, safe, and high-quality—all without damaging a single package.
What is Vacuum Decay Testing?
01
The Industry-Standard Leak Detection Method
Vacuum decay is one of the most trusted methods for detecting leaks in sealed food packaging. As a non-destructive, highly sensitive technique, it has become an essential part of quality control for manufacturers around the globe. This guide will walk you through the vacuum decay process, its benefits, and how it can help safeguard the integrity of your packaging.
02
Non-Destructive Testing
Vacuum decay testing is a non-destructive method used to detect leaks by measuring pressure changes inside a test chamber. When a vacuum is applied to the packaging, any leaks will cause air to enter the chamber, which results in a measurable pressure rise. This test method is particularly effective for detecting small leaks that could compromise the product’s shelf life or safety.
How Does Vacuum Decay Work?
01
Preparation
The sealed package is placed inside a test chamber, and the chamber is sealed.
02
Vacuum Application
A vacuum is applied to the chamber, reducing the internal pressure.
03
Monitoring
The pressure inside the chamber is monitored over a set time period. If there is a leak, air will be drawn into the package, causing a rise in pressure.
04
Analysis
The system analyzes the pressure change to determine if the package is airtight or has a leak.

Benefits of Vacuum Decay Testing
Non-Destructive
Unlike traditional methods, vacuum decay does not damage the packaging or product, allowing for retesting or further examination.
Efficiency
The vacuum decay method is fast and automated, making it ideal for large-scale production environments.
High Sensitivity
This method can detect very small leaks that other techniques might miss.
Compliance Ready
Vacuum decay testing is recognized by global regulatory bodies and aligns with industry standards, such as ASTM F2338.
When Should You Use Vacuum Decay Testing?
For Ensuring Packaging Integrity in Sensitive Products
Vacuum decay testing is well-suited for most food items, pharmaceuticals and medical devices, because of the safety and quality aspect. It can detect microleaks that are often missed by traditional testing methods.
When a Non-Destructive and Reproducible Test is Required
Vacuum decay testing is well-suited for most food items, pharmaceuticals and medical devices, because of the safety and quality aspect. It can detect microleaks that are often missed by traditional testing methods.
To Achieve High Sensitivity and Quantitative Data
Vacuum decay testing is well-suited for most food items, pharmaceuticals and medical devices, because of the safety and quality aspect. It can detect microleaks that are often missed by traditional testing methods.
For Operator-Independent Results and Faster Testing
Vacuum decay testing is well-suited for most food items, pharmaceuticals and medical devices, because of the safety and quality aspect. It can detect microleaks that are often missed by traditional testing methods.
Best Practices for Vacuum
Decay Testing
Regular inspections
Regularly inspect the test chamber and seals to avoid false positives.
Setting appropriate parameters
Set the appropriate test parameters (vacuum level, test duration) based on packaging type.
Maintain Detailed Documentation
Maintain detailed documentation for regulatory compliance and quality assurance audits.
