Hot Fill Packaging

Some foods can benefit from being packaged and sealed immediately after cooking – while still very hot.  Products like soups, cooked salsas, and sauces are often heated for some time to the boiling point (or close to it) which eliminates most bacteria.  If it can be packed in an air-tight container before it cools, this can reduce the opportunity for bacteria to enter into the package, which can extend shelf life without the use of preservatives.  However, contents that are still hot when they are packaged can add some complexities to the process.  How can you heat seal a container with extremely hot contents and make sure the seal stays intact?  This is where our hot fill packaging products and techniques come into play. There are several factors to consider during the hot fill packaging process.  These factors include (but are not limited to) cooling time, film hot-tack, rim contamination, and the materials used for the container and film.  That’s where the expertise of Teinnovations is key.

Hot Fill Packaging: Things to Consider when Utilizing this Process


  • Provides better shelf life.
  • Need to ensure the film the does not break when filling the hot contents (or shortly thereafter) to provide the processing benefits. Teinnovations is skilled at helping with this process.
  • Elimination of rim and seal surface contaminants. Teinnovations has films that are designed so that they seal out even minor contaminants.


  • Higher risk of the film not being sealed properly.
  • The hot filling process can result in the seal breaking more often during cooling.
  • The right equipment and process to quickly chill the product immediately after the hot-fill process is needed.
  • Improper chilling of the product could result in condensation of hot water vapors, which could cloud the film.

The good news is that all of the downsides can be mitigated with the proper equipment and know-how. That’s where Teinnovations comes in!
