Difference between blister, Skin, and Clamshell Packaging

Having the right packaging includes different categories, but what are the differences between the three. When it comes to packing, clamshell, skin, and blister all have unique properties, but let’s talk about each of them, and the benefits, along with downfalls and environmental impacts of each as well.


Skin is literally a plastic packaging that sometimes has a heat seal coating. The plastic substrate within this is heated up, and then put over the product with a cardboard backer, and from there, vacuum sealing is occasionally used to secure and ensure a good fit. The substrate will bond to the heat-seal that’s coated on the cardboard. The skin packaging does feel like a blister pack, but this usually takes the product shape, rather than being forced prior to using this. Typically, fishing supplies, meats, fish, hardware, and the like are essentially used in this.  The problem with these though is that it can be annoying to open up without the use of scissors, and this is the most troublesome to open, so remember that when you’re choosing one type of packaging.

Next is blister packaging, which is used in protecting goods that consumers have, perishables, along with pharmaceuticals. The main dynamic behind this is that it’s made from thermoformed plastic. The backer, or paperboard, aluminum foil, or a plastic substrate is applied to the back of this and used to keep the products inside.

The dual folding blister packs that come without a cardboard backer or a seal is known as a clamshell. This is good for protecting the products from damage externally, and other threats, including humid air, along with contamination for longer periods of time. The opaque blister packs are known for protecting products that are sensitive to the rays of the sun, so remember that when you’re choosing the type of packaging. These usually are good but the problem is that they tend to be found a lot in the ocean, but they do break down. They are the most eco-friendly of the three options.

Finally, you’ve got clamshell, which is essentially two shapes brought together. Have you ever grabbed lunch from a food truck, or even those places where you get hot food in them, then you’ve used clamshell packaging before. This is super easy, and they’re good for the environment.  Usually, you can burn them or recycle them, and they can handle a lot of goods. The one downside is they aren’t good at sealing and protecting freshness, and are very easy to puncture.

When choosing packaging, you have a few options here and there, and by choosing the correct options, you’ll be able to easily, and without fail, create the best and most worthwhile system that you can, and in turn, rate a better result for yourself as a person, and in turn, create a more rewarding experience in terms of processing and recycling materials.  You can choose the packaging that does best fit you as well too.
