I. Definition of Overwrapping Packaging and Shrink Wrapping

Overwrapping Packaging

Overwrapping packaging is only feasible for products with flat sides, or say, those that come in cubic or cuboid shapes.

A piece of film is to be wrapped over the product and the fringes and leftover parts are folded and sealed on the two end sides of the product thus forming a diamond-like sealing style which is also called Tuck and Fold Seals (also known as cigarette-style seals).

The shrink wrapping is during a process in which a product goes through a tunnel where it is covered over by a plastic film bag. The film is then heated to shrink tightly around and product and then an L-shaped sealing line is formed by which the film wrapping packaging can be torn.

 


II. Benefits and Disadvantages of Overwrapping and Shrink Wrapping

Both overwrapping and shrink wrapping offer some advantages in terms of manufacturing.

The advantageous features of overwrapping packaging are as follow:

  • Promotional Features and Attractiveness:
    Overwrapping packaging principally focuses on giving the product a sense of luxury and superiority. A decent and sleek packaging look is created with the diamond-like seal style / cigarette-style seal formed and the product looks in a neat and high-quality finish.
  • Versatility: 
    Overwrapping packaging is not only restricted to the secondary packaging but also the primary packaging such as that for soap. Whatsmore, it is also applicable for multipack overwrapping in order to bundle several products together.
  • Containment-Proof:
    Overwrapping keeps the content from dirt for exterior context.

The advantages of shrink-wrapping are as listed below:

  • Wide application:
    In contrast with overwrapping packaging which can only be used for cubic or cuboid items, shrink wrapping can be applied for products of miscellaneous shapes and styles. Shrink wrapping can be also used for larger size objects.
