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.

Pressure Decay Leak Testing Systems
Pressure Decay Leak Testing Systems are instruments that detect and quantify a leak by measuring the pressure drop over specified amount of time. Any specimen that is inflated will stay inflated if it is leak tight. On the other hand, of a leak exists in the inflated specimen, air will escape through the orifice and decrease the pressure inside the specimen. The higher the pressure drop, the high the leak.
Roots Blower Vacuum Pumps
Roots Blower Vacuum Pumps are used when a large amount of Volumetric Airflow is Required. Root Vacuum Pumps cannot operate independently and must be used in conjunction with another roughing pump such as Rotary Vane Pump or Piston Pump. The advantages of a Roots Vacuum Pump is that the Pumping Speed can be increased by a factor of 5 up to a factor of 10; meaning that a 20 CFM Rotary Vane Vacuum Pump can now be boosted to pump 120 CFM!

Related Articles: Force Decay Leak Testing
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.
