Before we get into the dynamic applications of thermoform packaging, we should quickly go over what thermoforming is in the first place, as it will bring clarity to its widespread use in packaging.
In short, thermoforming is a process wherein a plastic sheet is heated to a temperature that makes it pliable enough for forming into specific shapes in molds. After the molded shape is formed and cooled, it is trimmed as necessary to reach the final specs of the required design.
Popular Uses Of Thermoform Packaging Technology
There are a myriad of different ways in which thermoforming packaging can be put into practice. Three of the most common applications include: trays and lids, clamshells, and blisters.
- Trays and Lids. Trays are commonly used for items like sets of tools, boxes of chocolates, or even disposable deli platters. The lids, then, would be used to cover the trays.
- Clamshells. Clamshells are custom-fit packages that are usually made from rigid Polyvinyl Chloride (PVC). Each clamshell will often feature a hinge (like the back of a clam), that folds over to secure a product (or products) in place, via buttons or snaps that fit together to lock the product in place. Sometimes clamshells will also have a hole at the top for hanging on a peg at a retail outlet.
- Blisters. Blisters are custom-formed cavities, also referred to as “pockets” that are usually glued to a printed cardboard backing once the product is in place.
While there are certainly other applications for thermodynamic packaging, these are among the most popular in use today.
