Understanding Sterilite Container Materials
Types of Plastics Used by Sterilite
Sterilite manufactures its containers from various types of plastics, each possessing unique properties and suitability for different applications. Among the most common plastics used are polypropylene and polyethylene. Polypropylene, often identified with the recycling code number five, is a relatively sturdy and heat-resistant plastic. Polyethylene, available in high-density and low-density forms, is another frequently used material. High-density polyethylene, or number two, is known for its strength and chemical resistance, while low-density polyethylene, or number four, is more flexible. Understanding the specific type of plastic used in a Sterilite container is the first step in assessing its potential for food storage.
Identifying Plastic Types
Determining the type of plastic used in a Sterilite container is usually straightforward. Most containers feature a recycling code stamped on the bottom, typically within a triangle. This code indicates the type of plastic resin used in manufacturing. In addition to the recycling code, some containers may include other markings or labels that provide information about the material composition and intended use. Consulting the Sterilite website or product packaging can also provide valuable details about the materials used in specific containers.
What “Food Grade” Means
The term “food grade” refers to materials that are deemed safe for contact with food. These materials must meet specific standards set by regulatory agencies like the Food and Drug Administration (FDA) to minimize the risk of chemical migration or contamination. Food-grade plastics are manufactured using approved substances and processes that ensure they do not leach harmful chemicals into food. While Sterilite offers a wide range of containers, it’s important to determine whether specific products are explicitly labeled as food grade. The absence of a “food grade” designation doesn’t necessarily mean a container is unsafe for all food storage, but it does warrant further investigation and caution. It’s also worth noting that the Food and Drug Administration has regulations in place regarding the types of plastics that can be used in contact with food, ensuring they meet certain safety criteria.
Are Sterilite Containers Food Safe? The Nuances
Generally Considered Safe… Under Certain Conditions
Many Sterilite containers are considered safe for storing food under specific conditions. At normal temperatures, they are often suitable for storing dry goods like flour, sugar, and snacks, as well as leftovers in the refrigerator. However, caution is advised when exposing these containers to extreme temperatures. Most Sterilite containers are not designed for microwaving, as the heat can cause the plastic to warp or release chemicals into the food. Similarly, freezing food in Sterilite containers can make the plastic brittle and prone to cracking, potentially compromising the food’s safety and integrity.
Potential Concerns
One of the primary concerns surrounding the use of plastic containers for food storage is the potential for chemical leaching. Although most Sterilite products are now manufactured to be free of Bisphenol A, a chemical previously used in plastic production, it’s essential to be aware of the possibility of other chemicals migrating from the plastic into the food, especially when exposed to heat or acidic conditions. The extent of chemical leaching can depend on factors such as the type of plastic, the temperature, and the duration of contact between the food and the container. Over time, repeated use and washing can also degrade the plastic, increasing the likelihood of chemical migration. Some types of food, particularly those that are highly acidic or oily, may also promote leaching.
Sterilite’s Stance on Food Safety
Sterilite maintains that its containers are safe for their intended use, stating that they comply with all relevant regulations and safety standards. The company often provides information on its website and product packaging regarding the materials used and recommended uses. While Sterilite emphasizes the absence of Bisphenol A in many of its products, it’s crucial to verify this information for specific containers and to adhere to the recommended usage guidelines. Additionally, Sterilite often provides detailed information on the specific resins used and their compliance with safety regulations.
Best Practices for Using Sterilite Containers for Food Storage
Selecting the Right Container
When using Sterilite containers for food storage, choosing the right container for the specific purpose is essential. If possible, opt for containers explicitly designed and labeled for food storage. Consider the type of food you intend to store and select a container that is appropriate for its properties. For example, airtight containers are ideal for storing dry goods to prevent moisture and pests, while containers with secure lids are better suited for liquids and leftovers.
Safe Usage Guidelines
To minimize potential risks, it’s crucial to follow safe usage guidelines when using Sterilite containers for food storage. Never microwave Sterilite containers unless they are specifically labeled as microwave-safe. Allow food to cool completely before placing it in the container and refrigerating to reduce the risk of condensation and bacterial growth. Avoid storing highly acidic or oily foods in Sterilite containers for extended periods, as these types of foods may increase the likelihood of chemical leaching. Wash Sterilite containers thoroughly after each use, using warm, soapy water or a dishwasher if the container is dishwasher-safe.
Recognizing Signs of Degradation
Regularly inspect Sterilite containers for signs of degradation, such as cracks, discoloration, warping, or a sticky surface. These signs indicate that the plastic may be breaking down and that the container should be discarded. Continuing to use a degraded container can increase the risk of chemical migration and compromise the safety of the food stored within. Proper disposal of the container also helps in maintaining a safe and healthy environment.
Alternatives to Sterilite for Food Storage
Glass Containers
Glass containers are a popular alternative to plastic for food storage, offering several advantages. Glass is non-reactive, meaning it does not leach chemicals into food, and it is also easy to clean and sterilize. However, glass containers can be heavier and more fragile than plastic, making them less convenient for some users. The breakability of glass is a significant drawback, especially when handling hot or frozen contents.
Stainless Steel Containers
Stainless steel containers are another excellent option for food storage, known for their durability, non-reactivity, and resistance to corrosion. Stainless steel does not leach chemicals into food and is easy to clean and maintain. However, stainless steel containers can be more expensive than plastic and are not transparent, making it difficult to see the contents without opening them. The cost factor is a crucial consideration for those looking for budget-friendly options.
Other Food-Grade Plastic Containers
In addition to Sterilite, many other brands offer food-grade plastic containers that are designed for safe food storage. Some of these containers are made from specialized plastics like Tritan, which is known for its durability and resistance to chemical leaching.
