But a question that frequently arises amongst discerning consumers is: What kind of plastic are OXO POP Containers made of? This is a crucial inquiry, as the type of plastic used directly impacts not only the durability and longevity of the containers but also their safety for food storage and their overall environmental footprint.
This comprehensive article will delve deep into the materials that make OXO POP Containers so effective, exploring the specific types of plastic employed, their inherent properties, and why OXO has chosen these particular materials. We’ll also touch upon the safety considerations associated with these plastics and discuss what OXO is doing to address sustainability in their product lifecycle.
Unpacking the Material: The Primary Plastic in OXO POP Containers
The vast majority of OXO POP Containers are constructed from a specific type of plastic known for its excellent clarity, impact resistance, and food-safe properties. The primary material you’ll find is BPA-free SAN (Styrene Acrylonitrile).
Understanding SAN: Properties and Advantages
SAN is a copolymer, meaning it’s made from two monomers: styrene and acrylonitrile. The combination of these two components creates a plastic that offers a compelling balance of desirable characteristics.
Clarity and Aesthetics
One of the most immediately noticeable features of OXO POP Containers is their exceptional clarity. This is a direct benefit of using SAN. Unlike some other clear plastics that can appear cloudy or yellow over time, SAN maintains its transparency. This clarity is not just for aesthetics; it allows users to easily see the contents of the container, eliminating the need to label every single item (though labeling is still a good practice for organization). This visual access is particularly beneficial in pantries, where you can quickly identify what you need without rummaging through opaque containers.
Durability and Impact Resistance
OXO POP Containers are designed for daily use, and SAN plastic is well-suited for this purpose. It possesses good rigidity and is remarkably resistant to cracking and shattering, even when dropped. This impact resistance is a significant advantage over more brittle plastics, ensuring that your investment in these containers will last. The robust nature of SAN contributes to the overall longevity of the POP system, reducing the need for frequent replacements.
Chemical Resistance
SAN exhibits good resistance to many common chemicals, including oils, acids, and bases. This is important for food storage, as it means the plastic is unlikely to degrade or react with the foods stored within. This chemical inertness is a key factor in ensuring the safety and integrity of the stored food.
Temperature Tolerance
While not designed for extreme heat, SAN has a reasonable temperature tolerance. It can generally withstand typical kitchen temperatures, including refrigeration and short periods in the microwave (though caution is advised for microwaving plastic). It’s important to note that prolonged exposure to high heat can deform or damage SAN.
Food Safety and BPA-Free Designation
Crucially, the SAN plastic used in OXO POP Containers is certified as BPA-free. Bisphenol A (BPA) is a chemical that has raised health concerns due to its potential to leach into food and mimic hormones. OXO’s commitment to using BPA-free materials ensures that their POP Containers are safe for storing food, including infant formula and other sensitive items. This is a non-negotiable aspect for many consumers when choosing food storage solutions.
Why SAN Over Other Plastics?
OXO’s choice of SAN is a strategic one, prioritizing a blend of performance, safety, and user experience. While other plastics might offer certain advantages, SAN strikes a compelling balance. For instance:
- Polypropylene (PP): Often used for food containers, PP is durable and often microwave-safe. However, it can be less clear than SAN, and its stiffness can sometimes be less appealing for clear storage solutions.
- Polyethylene Terephthalate (PET): Commonly used for beverage bottles, PET is highly transparent but can be more prone to scratching and is generally not recommended for repeated high-heat applications.
- Acrylic (PMMA): While also very clear and rigid, acrylic can be more brittle and prone to cracking than SAN.
SAN offers a superior combination of clarity, impact strength, and food safety that aligns perfectly with the OXO POP Container’s design goals.
Beyond the Body: Other Materials in the OXO POP Container System
While SAN forms the transparent body of the container, other components are necessary to complete the POP system. These include the lid, the push-button mechanism, and the gasket.
The Lid and Button Mechanism: ABS and Silicone
The lid and the iconic push-button mechanism of OXO POP Containers are typically made from ABS (Acrylonitrile Butadiene Styrene). ABS is another robust thermoplastic known for its toughness, rigidity, and excellent impact resistance. It’s the same type of plastic used in many durable goods, including LEGO bricks, automotive parts, and electronic casings.
The ABS used for the lid and button is chosen for its durability, ensuring the mechanism withstands repeated pressing and the lid can withstand the stresses of daily use and washing. Like SAN, the ABS used in OXO POP Containers is also BPA-free, further reinforcing the commitment to food safety.
The airtight seal, essential for keeping food fresh, is achieved through a flexible silicone gasket. Silicone is a synthetic polymer known for its excellent flexibility, elasticity, and resistance to temperature extremes. Its ability to create a tight seal without degrading or cracking makes it the ideal material for this critical function. Silicone is also inert and safe for food contact.
The Gasket: Ensuring an Airtight Seal
The silicone gasket is arguably the unsung hero of the OXO POP Container. Its pliable nature allows it to compress effectively when the lid is closed, creating an airtight and watertight barrier. This prevents air and moisture from entering or escaping, which is fundamental to preserving the freshness and quality of stored food. This seal is what truly differentiates POP containers from many other food storage options.
