3 Primary Types of Overwrapping Packaging: Application, Pros and Cons

Overwrapping as a Versatile Kind of Plastic Film Wrapping Packaging

Widely used for products such as cosmetics, fragrances, coffee and tea boxes… overwrapping packaging (overwrap packaging) is recognized as one of the most versatile forms of plastic film packaging. But…

Here in this post, we talk about the different kinds of overwrapping packaging and give a to-depth introduction together with the pros and cons of them.

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

Just as its name indicates, the film wrapping carton at the horizontal end is shrunk totally by heat to seal the overwrapping packaging. 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 such as overwrapping where the conjunct two sharp edges of the folded film’s fin are sealed slightly in a dot area to finish the sealing, where the major rest part remains in a sleek manner without being shrunk the heat. 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

Strip-sealed overwrapping somehow resembles spot-sealed overwrapping now that there is just a limited area shrunk by heat to secure the packaging. Yet, strip-sealed overwrapping is usually used for large carton sizes with a rectangular cross-section. 

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.
