Primary Tips to Define the Type of Overwrapping Packaging

The typical features of overwrapping packaging are that the film is tucked and folded into a diamond shape and then sealed, shrunk, and secured by heat. The overwrapping packaging can be defined into three major types:

  • Fully-Sealed Overwrapping
  • Spot-Sealed Overwrapping
  • Strip-Sealed Overwrapping

Each of them is to be used based on the size of the product and with the requirements of the customer taking into consideration.


Fully-Sealed Overwrapping

Fully-sealed overwrapping is the most common form of overwrapping packaging due to its excellent compatibility with a wide range of carton sizes.

The advantage of fully-sealed overwrapping is that it is the most secure and solid overwrapping. However, as the horizontal end is totally shrunk by heat it is inevitable that fully-sealed overwrapping carries more evident wrinkles that the other forms of overwrapping.



Spot-Sealed Overwrapping

Spot-sealed overwrapping is often used on cartons with a fine square cross-section and high-value-added products such as luxury cosmetics and fragrances. Spot-sealed overwrapping is the most elegant and sleek film packaging due to its succinct yet charming appearance, however, spot-sealed overwrapping is restricted to carton boxes with square cross-sections and due to the tiny sealed area, it might be not suitable for large cartons.



Strip-Sealed Overwrapping

The frontlines of the folded film reaching from the front and rear panels overlap each other thus forming a rectangular overlaid area, which is to be sealed by the heat to secure the packaging. Strip-sealed is just like a remedy between the spot-sealed and fully-sealed overwrapping, with concession made between the secure and appearance.
