4 Leak Detection Techniques in Food Packaging


It is evident that every product needs proper packaging to prevent food contamination and maintain the reputation of the manufacturer. Food packaging must undergo a test to determine if it has any defect. Continuous evaluation of food product packaging saves manufacturers a lot of money. Food package leakages can easily taint the reputation of a company.

Investing in leak detection equipment is the best way manufacturers can eliminate unnecessary costs. Checking irregularities in food packaging material enable manufacturers to prevent food from going bad. Here are the four primary techniques for food packaging leak detection.

1. Altitude Simulation Method

The technique is suitable for leak detection in products that are transported through the air. It ensures that commodities do not collapse when at high altitudes. That way, manufacturers save a lot of money by making sure the product gets to the customers in excellent condition. You cannot perform this test while on air. Manufacturers use a vacuum chamber to test if the product is suitable for air transport.

2. Bubble Emission

It is an appropriate leakage testing technique for products that contain air. It involves putting packaging materials undergoing test into the water. The presence of bubbles in the packaging material means the test is positive. Manufacturers should not take such products to the market. That way, they will protect their reputation and save a lot of money since products with defects will not get to the market. Bubble emission test may be used for any packaging material to determine the point of burst on the seal.

3. Detection of Gas Leakages

Gas leak detection is suitable for tracing holes in food packaging materials. Over time, it has become a useful leak detection technique in food packaging. The method is also appropriate for commercial and industrial leak detection. Helium, hydrogen, and carbon monoxide are some of the gases that undergo gas leak detection test. It is an effective method for manufacturers to determine if their food packages are allowing gas to leak.

4. Dry Chamber Technique

It is a suitable technique for manufacturers to test leaks in liquid products such as beverages. It makes it easy for manufacturers to distinguish leaking products. It involves placing a product into a chamber before setting it in a vacuum. It uses an absorbent material to test if a foodstuff packaging is leaking. The presence of any liquid means the test is positive.

Product packaging is an essential component of the foodstuff industry. Manufacturers must strive to ensure that their packaging meets the set standards. Without testing the packaging material, a product may not provide customers with the desired service. Any of the above leak detection tests can enable manufacturers to determine the condition of their products.
