A Multi-faceted Approach to Effective Food and Medicine Packaging Testing

Keywords: Gas composition, Shelf life, Barrier property, Air-tightness, Head-space gas analysis, Leak detection, Permeation testing


Packaging quality is of great importance in maintaining food and medicine quality. Even with controlled gas mixtures and high-barrier materials, gas composition inside packages can change over time, impacting product shelf life.

Test methods and instruments are designed to assess factors affecting gas composition:

Barrier Property: This test measures a material's resistance to gas permeation. Labthink permeation test series test high barrier material packages, providing a more accurate picture.






Air-tightness: Leakage can significantly compromise packaging. For soft packages, positive pressure methods (Labthink C660M Leak and Seal Strength Tester) inflate the package to identify weak points. Negative pressure methods create a vacuum to achieve the same goal (Labthink C660B Leak and Seal tester). Screw-top containers are tested for seal integrity between cap and bottle using similar instruments.





HeadSpace Gas Analysis: This test analyzes the gas composition in the empty space at the top of a package. It helps assess remaining gases after packaging and the release of adsorbed gases over time. Labthink C650M and C650H Headspace Gas Analyzer are developed for this purpose. Analyzing the gas concentration curve allows for a more comprehensive understanding.

Quality Requirements of Lithium Ion Battery Separators

Business Challenge Lithium-ion batteries have one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. This makes them one of the most popular types of batteries for portable consumer electronics in today’s marketplace. Lithium-ion batteries can be found in cameras, laptops, power tools, toys and more. However, as recent well-publicized recalls demonstrate, they can pose a risk of fire and overheating. In addition, they can suffer from a reduced lifespan if not properly treated. As a result, new and stricter requirements are being implemented globally to address potential hazards, leaving manufacturers and purchasers of products containing lithium-ion batteries to meet increasing requirements and overcome safety concerns. Lithium Ion Battery Separators A Lithium Ion battery Separator is a permeable membrane placed between the anode and cathode of a battery. The main function of a separator is to keep the positive and negative electr...

Comparative Analysis of Aluminum-Coated VMPET and VMBOPP Oxygen Transmission Properties

Aluminum-coated films offer a cost-effective alternative to pure aluminum foil for packaging applications requiring good barrier properties. However, the effectiveness of these films can vary depending on the substrate material used. This study investigates the Oxygen Transmission Rate (OTR) of VMPET (vapor-deposited aluminum on PET) and VMBOPP (vapor-deposited aluminum on BOPP) to assess the influence of the substrate on barrier performance. The OTR test employed the coulometric method (equal pressure) following the standard ASTM D3985. This method utilizes a controlled environment chamber to measure the rate of oxygen permeation through the film sample. Labthink C230H Oxygen Transmission Rate Test System was used for this study. This instrument is designed and manufactured based on the coulometric sensor method (aka. equal pressure method) and conforms to ASTM D3985. This instrument can be used to measure the oxygen transmission rate of barrier materials with high and medium barrier ...

Introducing Vacuum Decay Testing Method for Pharmaceutical Packaging Integrity

Maintaining the integrity of pharmaceutical packaging is fundamentally essential for safeguarding product efficacy and patient safety, and vacuum decay testing stands as a highly reliable non-destructive method for verifying this integrity. This technique, particularly effective for blister packs, vials, and pre-filled syringes, identifies leaks without compromising product sterility or efficacy. Vacuum decay testing leverages the principle that a sealed package, when subjected to a vacuum, will exhibit predictable pressure changes if it's leak-free. Conversely, a leaking package will show a different pressure profile. Specific Vacuum Decay Techniques:   Differential Pressure Transducers: These precise sensors measure the difference in pressure between the vacuum chamber and a reference chamber. This allows for detection of very small leaks. Absolute Pressure Sensors: These sensors measure the absolute pressure within the vacuum chamber, providing data to determine the rate of pres...
