Monitoring the Food Packaging Process with Temperature Sensors

One of the most damaging results of leakages is contamination of food products. However, there is no other way of getting rid of cases of improperly sealed packages other than ensuring that they don’t happen. In an attempt to provide a more efficient leak detector, a recent innovation effort has come up with a sure way of reducing cases of improperly sealed packages or at best, completely getting rid of them.

Manufacturers can now rest assured that their reputation is in safe hands and they don’t have to make huge losses in recalled products. All they have to do is use a thin-film temperature sensor that allows them to monitor the packaging process while still in-line. While you can easily check every package for leakage, you don’t have to go through the tedious and time-consuming process that involves spot checks that are sometimes unreliable.

Time to Abandon Tedious Leak Detector Methods

Often, the sealing process involves the use of heat. Nevertheless, you can’t always be sure that the seal will hold. A simple alteration of the temperature can result to a poor sealing job. If it is too high, the film tube that holds the packaging material together burns. If it happens to be too cold, the sealing will not be tight enough. A temperature sensor is, therefore, excellent news for manufacturers who have been used to going to great pains to ensure that leaks are detected.

How It Works

To get direct feedback on the packaging process of every unit, the temperature sensor is directly applied to the sealing bar. This enables the adjustment of the temperature in case it is too high or too low. In addition, it allows early correction of any sealing problem before too many improperly sealed packages are released from the packaging line.

The method also helps pick out products that may have interfered with proper packaging by getting in the seam. During the sealing process, the sealing bars surrender some of their heat to the sealing films which results to a little cooling down. If there is any product trapped in the seams, it will also get some of the heat, thus resulting to a quicker cooling of the bars than would be the case if it wasn’t there.


Improper packaging of food products does no good to the manufacturer. With every packaging mistake, the reputation is put at risk. At minimum, the customers will have questions about the intake of a poorly packaged product. It can easily get worse when one unhappy customer puts up a spirited campaign against not only the use of the product but also other brands associated with the manufacturer. For that reason, every necessary measure, including the use of such a reliable leak detector as the temperature sensor, should be put into place before the release of food products into the market.
