How to Test Seal Integrity of:

Food Bars

This article will talk about how to test the seal integrity of food bars. You will understand what you will need to do in order to ensure good seal quality. This article covers the seal integrity testing of Breakfast bars, Chocolate candy bars, Crisped rice bars, Energy bars, Granola bars, Health bars, Protein bars, Fruit and Nut Bars, Meal Replacement Bars or any other food bar sealed with a flow wrapper.

Vacuum Sealed Packages

If you are vacuum sealing your packages, you are faced with a challenge when it comes to seal testing. How do you know that your process is consistently creating a good seal? How can you be sure that the vacuum inside you package will hold for the required amount of time?

Sachets Filled with Powder or Liquid

In this article, we will talk about how a vacuum chamber can be utilized as a tool to perform leak quality testing on Sachets filled with either powder or liquid. You can use an acrylic vacuum chamber or bubble leak test system to test for leaks in sachets filled with powder or liquid.

Spray Bottle Pump Leak Testing

In this article we will talk about several techniques used to quality leak test the pump of a spray bottle.

Quality Control of Seals and Seams of Canned Food or Food Containers

Food cans which are hermetically sealed or seamed are the most consumed type of food in the United States. Fully 60% of all food consumed in a given day in the US is either canned food or food from containers. Canned food seal failure can expose the consumer to an unnecessary amount of risk.

Vacuum Decay Leak Testing Systems

Vacuum Decay Leak Testing Systems are Instruments that detect and quantify a leak by measuring the drop in vacuum (pressure) inside the specimen. During a vacuum decay leak test, the specimen is placed into a vacuum chamber, the vacuum is pulled to a specified setpoint, and the drop in vacuum is monitored and recorded over time. If a leak in the specimen exists, the air will travel from a higher pressure (inside the specimen) to a lower pressure (vacuum chamber). As a results of the additional air, the vacuum levels will drop whereas a leak can be detected and quantified.

Belt Drive Rotary Vane Vacuum Pumps

A Belt Drive Rotary Vane Pump is almost identical to a Direct Drive Rotary Vane Pump. The only difference between the two is that the belt drive Rotary Vane Vacuum Pump is driven by a belt. There are several advantages why a belt drive vacuum pump would be preferable. One of these reasons is that the belt drive Rotary Vane Vacuum Pump runs at a slower RPM therefore the temperature created is lower, the wear and tear is less, and the overall lifetime of the pump is longer. The disadvantages are a lower CFM and performance.

Our Work: Vacuum Testing of Lithium Ion Batteries, Thin Film, Fuel Cells, Supercapacitors, and Nano materials

This vacuum chamber is a modification to our basic acrylic vacuum chamber 12 inch, removable lid model; except that our customer requested additional ports and electrical feed-through for testing of electrical equipment under vacuum. You know, I wish we would have asked them for more details on what they were doing with this chamber; their short and concise answer was that they were using our chamber to perform scientific work on the subjects of: lithium ion batteries, thin films, fuel cells, super-capacitors, and nano-materials testing in a vacuum environment.

Force Decay Leak Testing is a very popular quantitative leak testing method used to quality test package and product integrity due to its ability to detect small leaks which cannot be seen through visual inspection. In this method, the test specimen is internally inflated by either internal pressurization or vacuum force. The inflated test specimen will, in turn, apply a force on a pressure transducer. Finally, the change in force applied by the inflated specimen over a specified time is observed.
