There are different types of plastic, and PET plastics are just one category. PET packaging is some of the industry’s most commonly seen in consumer products because it is so versatile and can be manipulated into various forms.
When processed properly, PET plastics are crystal clear. Otherwise, PET plastics develop a crystallized appearance.
You don’t have to know what PET is in order to use it every day. PET plastic is what water and soda bottles are made out of, because it is lightweight, relatively inexpensive, malleable, and, perhaps most importantly, perfectly clear. That crystal-clear appearance makes PET packaging an easy choice for plastic manufacturers, because it provides a perfect showcase for a product that you want your consumers to see clearly, like spring water.
Safety and Security
Packaging companies also do a lot of work with PET plastics because it is safe. The National Association for PET Container Resources reports that the Food and Drug Administration approves of PET plastics for handling food and beverages, so it’s perfectly safe for virtually anything you can find at the market. PET packaging also resists leaking, which makes it safe not only for food and drinks, but for chemicals that you don’t want escaping into your home, like cleaning products. These strong plastics withstand both physical pressure and temperature changes, keeping your product safe and sound.
Risks of PET Packaging
This type of packaging doesn’t carry any risks for the consumer—only the plastic manufacturer. When it is in its amorphous stage, a point at which it’s known as APET, it can crystallize. This sometimes happens in the thermoforming process, during which the plastic is treated with heat to mold or seal it. If the manufacturer isn’t careful during this process, thermoforming can lead to crystallization, which makes the plastic go from clear to hazy and cloudy, effectively ruining its once-pristine appearance.
