Similarities & Differences Between Vacuum Packaging & Shrink Wrapping

 



Due to the look of the finished product, vacuum packaging and shrink packaging are often easily confused with each other. Vacuum packaging and shrink wrapping both use transparent flexible packaging materials that appear conformed to the product being packaged. The conformed look of both looks to be airtight. This is one of many misconceptions of shrink wrapping and vacuum packaging.

Here are some of the similarities between the two:

  • Clear Flexible Packaging – Both forms of packaging often use clear bags or rolls of a plastic polymer film. There are certain exceptions, but the majority of vacuum packaged and heat shrink products use a clear film.


  • Heat Sealing – Both vacuum packaging and shrink wrapping use heat sealing to enclose the packaged product within the packaging.


  • Conformed Finished Look – Both forms of packaging have an exterior film conforming to the product being packaged.


  • Both are Often Used for Food Packaging— Both shrink wrapping, and vacuum packaging are often used for packaging foods and consumable items.


Below are some of the significant differences between vacuum packaging and shrink packaging:

  • Thickness of Materials – The packaging rolls used in vacuum packaging are much thicker than those used in shrink packaging. They are typically four times thicker than the material used in shrink packaging.


  • Machinery – Both packaging types use heat sealing. However, the machinery used to carry out this process is not the same. For vacuum sealing, only the sealed part requires heat. Shrink packaging requires heating the entire package to create the seal. Shrink packaging and vacuum packaging machines are not interchangeable.


  • Oxygen – This is another significant difference between the two types of packaging. The vacuum packaging process removes air from the package and creates a tight seal. This is done to increase the shelf life of food products. Shrink wrap requires heating the wrapping to create a tight seal. Adding heat would not be appropriate for every type of product.
