Polycarbonate and polypropylene are both types of thermoplastic polymers, but there are some key differences between the two. Polycarbonate is known for its longevity, making it an ideal choice for more demanding applications. Strong and exceptionally durable, polycarbonate can be manufactured as a transparent material.
It’s also highly resistant to stains and can handle extreme shifts in temperature. Polycarbonate is stable at temperatures ranging from approximately 100 to 210 degrees Fahrenheit. High-heat polycarbonate can handle extremes of up to 375 degrees Fahrenheit, but this variety of polycarbonate material lacks the transparency of its regular counterpart.
Polycarbonate is used for a wide variety of applications. It’s commonly used to produce consumer products, including personal protection equipment like safety goggles, as well as electronic discs. It’s also popular for manufacturing appliances, automotive moldings, and medical equipment.
Polypropylene also impresses with its strength and durability, but can’t handle the same temperature extremes as polycarbonate. Typically, polypropylene is only stable at 30 to 195 degrees Fahrenheit. At higher temperatures, it begins to lose integrity and its impact resistance suffers.
As it’s easy to shape and colorize, polypropylene enjoys many uses. It can be used to create all manner of plastic components, as well as a wide variety of consumer goods and medical products. As this thermoplastic polymer has a fiber-like construction, it’s also a good choice for manufacturing certain fabrics.
We’ve already touched upon the differences in thermal properties between polycarbonate and polypropylene, but it’s worth taking a closer look at how each material performs. Polycarbonate performs slightly better than polypropylene at higher temperatures, only distorting at around 285 degrees Fahrenheit, making it a better choice for more demanding applications.
As far as chemical resistance is concerned, polypropylene comes out on top. Polypropylene is particularly stable, with excellent resistance against a variety of oxidizers, acids, and other aggressors. Polycarbonate also boasts impressive chemical resistance, but can only handle exposure to relatively weak solutions and oxidizers.
In terms of strength and durability, both polymers perform well. Polypropylene wins out when it comes to overall toughness, but falls short when it comes to impact resistance. With a higher overall density, polycarbonate fares better against impacts, but is more susceptible to wear and tear.
Because it can withstand exposure to high temperatures, including boiling water, polycarbonate is a safe choice for food storage. FDA-approved polycarbonate is free of BPA and other chemicals, meaning there’s no need to worry about contamination of food products. Polycarbonate also resists chemical leaching particularly well, meaning foodstuffs won’t readily stain the material when it’s exposed to particularly high temperatures.
As well as being BPA-free and thermally stable, polycarbonate boasts many features and benefits that make it a sound choice for food storage.
Because of its increased density and higher tensile strength, polycarbonate is a more durable option than polypropylene. Because it can resist impacts well, it’s also a good option for bulk packaging and food processing applications. However, this doesn’t mean polypropylene is a poor choice for food storage, as the material holds up well to repeated use.
Many food storage containers need to be able to withstand exceptionally high temperatures. Polycarbonate delivers in this regard, coping well with temperatures of up to 275 degrees Fahrenheit before heat begins to distort the material.
If you’re looking to operate more sustainably, polycarbonate and polypropylene are good choices. Both materials can be recycled, although polycarbonate requires more complex recycling processes and specialized equipment. Polypropylene is relatively easier to recycle, with repurposed PP ideal for creating plastic packaging, automotive components, certain textiles, and more.
In addition to being a reliable food storage and packaging solution, polypropylene can be used for all manner of applications. It’s regularly repurposed into a fibrous form to make textiles, can be used to create an extensive selection of consumer products, and is often used to fashion automotive parts. Because of its high tensile strength and durability, it’s also a go-to for construction materials.
Can’t decide between polycarbonate and polypropylene for food storage solutions? Both materials are FDA-approved and safe for food contact. Both materials are free of harmful BPAs and can resist chemical leaching, making them a good option for storing high-temperature foods. Polycarbonate is more heat-resistant than polypropylene, meaning it can withstand exposure to higher temperatures in microwaves and other appliances.
If you’re looking for a more affordable solution, polypropylene is the better choice. What’s more, polypropylene has slightly improved food safety credentials than polycarbonate. However, the hard-wearing nature of polycarbonate makes it an effective choice if you need packaging that’s impact resistant. Looking for clear containers for food storage? Because of its improved transparency, polycarbonate may be a better fit for your needs than polypropylene.
Are you searching for a reliable food packaging solution? Bulk packaging made from thermal polymers like polypropylene is an ideal choice. Scoring well for durability and offering decent heat-resistant properties, it’s the perfect material for storing and transporting a wide variety of cold and hot foods. It’s also a smart option if you’re looking for health-friendly packaging, with no harmful BPAs to worry about. Furthermore, it’s a relatively cheap material, offering a more cost-effective option than other materials like polycarbonate.
