The snowflake symbol means the container is freezer-safe
The snowflake symbol on plastic storage containers indicates that the container is freezer-safe. This symbol is part of the Resin Identification Code (RIC) system, which classifies plastics according to their chemical composition. The snowflake symbol is a reliable indicator that the container can withstand freezing temperatures without deteriorating or compromising food safety.
The presence of the snowflake symbol assures consumers that their food will be optimally preserved in the freezer, minimising waste. This symbol is particularly useful for those who frequently cook large batches and wish to store leftovers in the freezer for later consumption. It is important to note that not all plastics labelled as freezer-safe are designed for long-term storage, so regular inspections for cracks or discolouration after freezing cycles are recommended.
The snowflake symbol is just one of several symbols that provide valuable information about the container's usage and safety. Other commonly found symbols include the food-safe symbol, represented by a fork and cup or a fork and wine glass, indicating that the plastic is safe for food storage. The microwave-safe symbol, denoted by wavy lines, signifies compatibility with microwave heating.
Additionally, the dishwasher-safe symbol, typically depicted as plates or water droplets, indicates that the container can be safely cleaned in a dishwasher. These symbols are crucial for promoting sustainability, as they enable consumers to make eco-friendly decisions and properly dispose of plastic containers. Understanding these symbols helps consumers make informed choices, ensuring safety for their families and the environment.

Other symbols indicate if a container is dishwasher-safe
Symbols on plastic containers are a great way to tell if they are dishwasher-safe, among other things. While there is no universally recognized symbol to indicate that an item is dishwasher-safe, there are several symbols that can tell you if an item is dishwasher-safe. These symbols are often pictured as a couple of circles, usually one smaller and one larger, that represent plates. These cartoon plates then appear as if they are being rained on, either with images of water droplets or diagonal lines. This symbol sometimes denotes that the item should only be placed in the top rack, especially if it is made of soft plastic.
Another common dishwasher-safe symbol features a wine glass, either positioned upright or tipped upside down, with water droplets falling on the glass. If you see a symbol that includes one large dish and one small dish being washed in a dishwasher on the bottom of your plate or glass, you can clean it using your dishwasher. This symbol also features a single plate sitting in a dishwasher rack with water droplets falling on the plate.
It is important to note that not all plastics and ceramics are dishwasher-safe. Different types of plastics have different melting points, and plastics with low melting points can become warped and degrade in the high temperatures of the dishwasher. Therefore, it is always a good idea to check the bottom of any item to see if it has a dishwasher-safe symbol.

Symbols on plastic containers indicate safe usage and address consumer health
Plastic containers are an integral part of our daily lives, but understanding the symbols on them is crucial for safe and sustainable use. These symbols are part of the Resin Identification Code (RIC) system, which identifies the type of plastic and its recyclability. By decoding these identifiers, you can make informed choices about plastic use, ensuring safety for your family and the environment.
The snowflake symbol on plastic storage containers indicates that the container is freezer-safe. It is resistant to freezing temperatures, making it suitable for freezing food items. This symbol is important as extreme temperatures can deteriorate plastic, and if containers aren't food-safe, it can cause chemicals to spread to food when taken out of the freezer.
Other common symbols on plastic containers include the food-safe symbol, a fork and cup or a fork and glass, which signifies that the plastic is safe for food storage. The microwave-safe symbol, represented by wavy lines, indicates compatibility with microwave heating. The dishwasher-safe symbol, often shown as waves, confirms that the plastic can withstand dishwasher cleaning.
Additionally, the recycling symbol, a triangle with arrows, indicates the recyclability of the plastic. It is important to note that not all plastics with this symbol are recyclable, and you should check local guidelines. Plastics labelled #1 and #2 are the most widely recycled. The BPA-free symbol ensures the absence of Bisphenol A, a potentially harmful chemical. These symbols provide valuable information to customers, ensuring safe food storage, freezing, heating, and cleaning. They also help consumers make eco-friendly decisions and contribute to sustainability.

The recycling symbol is a triangle with arrows and a number in the centre
The snowflake symbol on plastic storage containers indicates that the container is suitable for freezing food items. It is also known as the freeze-safe symbol. If you don't see this symbol, avoid putting your new containers in the freezer. Extreme temperatures can deteriorate plastic, and if containers aren’t food safe, this can cause chemicals to spread to food when removed from the freezer.
The recycling symbol, on the other hand, is a triangle with arrows and a number in the centre. This symbol indicates the recyclability of the plastic. Each number within the recycling triangle represents a specific type of plastic. For example, plastics labelled #1 and #2 are the most widely recycled. The numbers also indicate the type of plastic resin, and recycling guidelines may vary based on local facilities.
The recycling symbol is part of the Resin Identification Code (RIC) system, developed to classify plastics by their chemical composition. The numbers in the recycling symbol range from one to seven, with each number being a code for the specific plastic that your containers are made of. Most Tupperware is imprinted with the number five, representing polypropylene, a cloudy plastic generally considered food-safe.
In addition to the recycling symbol, there are other symbols that provide valuable information about the container's usage and safety. These include the food-safe symbol (a fork and cup), the microwave-safe symbol (wavy lines), the freezer-safe symbol (snowflake), the BPA-free symbol, and the dishwasher-safe symbol (plates or water droplets).

The absence of a snowflake symbol means the container is not freezer-safe
Plastic containers are ubiquitous in our daily lives, but understanding the symbols on them is essential for safe and sustainable use. These symbols are part of the Resin Identification Code (RIC) system, which classifies plastics by their chemical composition. By interpreting these symbols, you can make informed decisions about plastic usage, ensuring the safety of your family and the environment.
The snowflake symbol on plastic storage containers is a crucial indicator of their freezer-safe properties. This symbol, often enclosed within a triangle, signifies that the container is suitable for freezing food items. It indicates the plastic's resistance to freezing temperatures, assuring that it can withstand extreme cold without compromising the integrity of the container or the food inside.
However, the absence of the snowflake symbol serves as an important warning. It implies that the container is not designed to endure freezing temperatures and should not be placed in the freezer. Extreme temperatures can cause the plastic to deteriorate, leading to potential chemical leaching into the stored food items once they are removed from the freezer. Therefore, it is crucial to heed this symbol to maintain food safety and the longevity of your containers.
While the snowflake symbol is a critical indicator of freezer safety, it is important to note that not all plastics labelled freezer-safe are intended for long-term freezing. It is advisable to regularly inspect containers for any cracks or discolouration after freezing cycles, even if they bear the snowflake symbol. Additionally, some containers may not feature any symbols at all, so it is always recommended to refer to the manufacturer's instructions or website for specific guidelines.
In conclusion, the absence of the snowflake symbol on plastic storage containers is a clear indication that they are not freezer-safe. This knowledge is essential to prevent potential health risks and maintain the condition of your containers. Always remember to refer to the symbols and manufacturer's instructions before using plastic containers for food storage and freezing.
