A clamshell package, as the name implies, is comprised of two joined pieces of packaging material, which completely surround the item or product. Such packaging is typically made of thermoformed plastic, and the edges can be sealed if airtight protection is needed.
Materials of Food Clamshell Packaging
PET & PETG
This is an abbreviation for the thermoform plastic polyethylene terephthalate. PETG is polyethylene terephthalate glycol. These two types of plastic are used by many clamshell packaging suppliers. PET commonly is used for water bottles, but also is FDA-approved for food packaging, so it can be used to create some clamshell packaging. It provides strong moisture resistance and it's a strong, shatterproof plastic and an affordable option as well. PETG, which often is used as filament for 3D printers, also can be used for clamshell packaging although it is crucial that you select a clamshell packaging supplier with extensive experience with PETG, as it is a bit trickier to handle than PET. Like PET, this thermoform plastic is lightweight, impact-resistant and acts as an excellent moisture barrier. Both plastics are FDA-approved and can be used to hold a variety of foods and beverages. One advantage of PETG over PET is that the PETG is more heat resistant than PET. If you overheat PET, it becomes brittle and the plastic's appearance can become hazy.
HDPE
High-density polyethylene is another thermoform plastic that many clamshell packaging suppliers will use for retail packaging, and this material also is FDA-approved for food packaging. You will see HDPE used to create food tubs with lids as well as milk jugs, as well as shampoo, household cleaners and much more, including clamshell packaging. HDPE is lightweight and extremely strong and impact resistant. HDPE also is an excellent moisture barrier, even better than PET. Sustainability is great reason to consider using HDPE for clamshell packaging, as it is another material that is easy to recycle. Virtually all curbside recycling programs accept HDPE and PET, so it's easy for consumers to simply toss your packaging into a recycling bin and help it move on to its new life as something else.
OPS & HIPS
There are other plastics in the styrene family that can be used for clamshell packaging. OPS, oriented polystyrene, can be used to create clamshell packaging for many products, including food products. HIPS, or high-impact polystyrene, is, as its name suggests, highly impact resistant and it also is highly moisture resistant and FDA-approved. You often see HIPS used to make trays that hold cookies or crackers or perhaps items you would buy at the deli counter, but it can be used for other types of packaging, including clamshell packaging.
Starch-Based Bioplastics
While starched-based bioplastics have been around for decades, they have become more and more popular in the last decade, as consumers and manufacturers search for the most sustainable packaging options. The starch used for these bioplastics comes from a renewable source and can be used for retail and food clamshell packaging. Some bioplastics are compostable and some are biodegradable. Rather than being tossed into a recycling bin, these typically need to be placed in your compost bin or taken to a facility.
Advantages of Food Clamshell Packaging
Consumers Appreciate Being Able to See Food Before Buying It.
What shopper isn't enticed by the colorful vibrancy of healthy fresh food? Not only does a transparent clamshell package draw them in, but consumers are able to see all the way around the container and feel confident in the quality of their purchase. Most clamshell packages include anti-fogging treatment for clear viewing and a sturdy, leak-resistant closure system that allows people to easily open, close, and reopen the container when storing at home.
Clamshell Packaging Protects Fresh Food While Showcasing the Contents.
As a superior choice to plastic bags, clamshells help keep delicate fresh food from bruising or being otherwise damaged during shipping and transport to consumers' homes. In addition to being excellent for storing produce, clamshells are the perfect choice to protect bakery items that might otherwise be squished, and they keep potentially messy items like fruit-topped danishes neat and tidy.
Clamshell Containers are Cost-Effective, Recyclable, and Help Reduce Fresh Food Waste.
Clamshell packaging is coming down in price due to recycling efforts. This is good news for your bottom line. As a bonus, customers appreciate efforts at offering green packaging. Additionally, the popularity of clamshells for fresh food has spurred advancement in new technologies that have further reduced production costs, bring the price of the containers down. Also, using clamshell packaging is not only green from a recycling perspective but also helps the environment by cutting down on food waste.
Clamshell Packaging Can be Sealed for Safety with a Tamper-Evident Label.
Another huge benefit offered by the clamshell is that its visibility reassures customers that the food inside has not been tampered with or modified post-packaging. As a further measure of precaution, clamshells are often manufactured with safety tabs, shrink wrap, or c-wrap labeling as a tamper-evident seal. Safety first!
