Maintaining the integrity of a seal is a vital element in food product packaging and development. Every food manufacturing company should own a leak detection equipment to ensure high-quality production and maintenance of trust among the food product users. Companies have been using non-destructive methods in the Modified Atmosphere Packaging to ensure that products such as ketchup bottles, crisps, and food sachets are free from the tears and leaks before releasing them to the consumers.
Effects of Leaks
Small holes in the food products serve as entry points for the bacteria that would easily cause spoilage of food and reduction of the shelf life of the product. Additionally, items with compromised seals may have an effect on the company’s bottom line due to the increased losses. A consumer who falls sick after consumption of a food product with compromised seal integrity is highly likely to sue a company for liability. Manufacturers should be extra careful with the product packaging.
Offline Versus Online
Leak detection equipment is either online or offline. The offline system is manual and requires the manufacturer of the package to insert the sealed item into the testing chamber and then monitor the Carbon dioxide levels in the chamber. There is a compromise on the seal integrity if the sensor detects elevated CO2 levels. The online leak detector is the commonly used method since it can test large packages in a very short time. It has an automatic leak detector that separates the compromised items from the intact one as they move along a parallel conveyor belt.
Methods of Leak Detection
Leak detection equipment uses bubble emission tests, vacuum package tests, and dry chamber tests to check for any leaks on the products. The bubble emission test is the oldest leak detection method and involves placing a package in a chamber filled with water. The presence of bubbles confirms a compromised package. The dry chamber method involves placement of the item in a test chamber and then evacuation of the gas from the chamber. The high sensitive sensors detect entry of any gas into the chamber from the package. The vacuum method is similar to the dry chamber with the difference being that the sensors also identify the pressure change.
Manufacturers of packages should handle the manufacturing process with care to prevent losses of products and revenue. The potential customers are also highly likely to lose trust in your brand if they fall sick after consumption of foodstuffs from your company. Leak detection may lead to increased quality, productivity, and security. You can find more information at FlexPak.
