Clamshell packaging has been a craze in the world of marketing for decades, and it doesn't show any sign of slowing down. When it comes to shipping and packaging, the clamshell is a tried and true favorite. It's been in use for decades with few changes, but we're seeing that change these days. Below are different types of clamshell packaging.
Thermoform Clamshell Packaging
This type of clamshell packaging consists of a polystyrene base with a thin sheet of paper on top. Once the consumer places an item into the container, heat is applied to affix it to the packaging permanently. The biggest downsides to this style are that they only work for low-volume orders and that getting items out requires the use of a blade or box cutter. This is an ideal packaging choice for shipping items that need to be smashed during shipping, such as baked goods and chocolate-covered strawberries.
Plastic Clamshell Packaging
Plastic packaging comes in two types: thermoform and injection mold. Thermoform plastic clamshells consist of a thin sheet of paper, much like the thermoform packaging we discussed above. Still, it is wrapped around a hard plastic shell generally made out of either polypropylene or polyethylene. These containers allow for more protection than the thermal form, but both styles are made of non-recyclable materials.
Paperboard Clamshell Packaging
Paperboard clamshells are the most cost-effective option as they require very little packing material. This type of packaging consists of a thick paper shell wrapped around a polypropylene insert. When it comes time for the opening, there is no need to use a box cutter because these packages open using a perforation that allows the consumer to tear the clamshell open easily. These packages are ideal for shipping small products such as eyeglasses, garage door openers, and higher-priced items that benefit from a more upscale look.
Plant Fiber Clamshell Packaging
This type of clamshell packaging is made out of biodegradable material and is one of the most eco-friendly choices. Plant fiber also has a time and money-saving benefit in that there's no need for tape or extra pieces to secure it, as it can be closed using a staple or wafer seal. These types of clamshells are often seen as a slightly upscale option, and they're popular among companies looking to recreate that feeling of elegance without spending too much money.
Sugarcane Clamshell Packaging
The newest kid on the block, sugarcane clamshells, are made out of renewable sugarcane and provide a fantastic eco-friendly option that is stronger than paperboard packaging. Because this material is so strong, you can ship items with less packaging and waste less money doing it. The most notable downside to these types of packages is that they generally have a glossy finish, which can make for a less-than-appealing presentation. As with all eco-friendly options, companies tend to be willing to pay a bit more for this packaging as a way of improving their reputation and getting the word out about green initiatives.
Called foam-in-place packaging, this type of clamshell is a little different from the others in that it is usually meant for shipping extremely high-priced or delicate items. To create these packages, printers heat up styrofoam sheets and then mold them around the product using pressure. While this style does allow for extreme protection, there is a downside- these packages are extremely expensive to produce.
