Food-grade plastic is a type of plastic that has been approved for food storage and is designed to keep food untainted and unspoiled. It is crucial to identify food-grade plastic to ensure the safety and longevity of stored food items. The easiest way to determine if a plastic container is food grade is to look for a cup and fork symbol, which indicates that it is suitable for food storage. Other symbols to look out for include radiating waves, which mean the container is microwave-safe, dishes in water, indicating dishwasher-safe, and a snowflake, which means it is suitable for freezing. Food-grade plastic containers also usually have a recycling symbol with a number inside, typically 1, 2, 4, or 5, indicating food-safe plastic. When buying new containers, it is important to check the label or manufacturing details, as this information is usually provided in the product description.

What You'll Learn
Check the recycling symbol
Checking the recycling symbol is a reliable way to identify food-grade plastic. This symbol typically comprises a triangle with arrows and a number inside, usually stamped on the bottom of the plastic item. The numbers that indicate food-grade standards are 1, 2, 4, and 5, which correspond to different types of plastic. Number 2, for instance, denotes high-density polyethylene (HDPE), considered one of the best types of plastic for long-term food storage due to its stability and inert nature.
It's important to distinguish between "food-safe" and "food-grade" plastics. While "food-safe" plastics like HDPE can come into contact with food without causing immediate harm to consumers, "food-grade" plastics have undergone stricter testing to ensure they are safe for long-term food storage. These plastics are free from dyes and harmful chemicals that could leach into the food over time.
The recycling symbol on food-grade plastics may also be accompanied by other symbols that indicate specific uses. For example, a cup and fork symbol confirms that the plastic is suitable for food storage, radiating waves indicate that the container is microwave-safe, and a snowflake means it's suitable for freezing. These symbols provide additional information about the intended use and safety of the plastic item.
When purchasing plastic containers for food storage, it is crucial to check for these recycling and usage symbols. They provide important information about the type of plastic and its suitability for food contact. By understanding these symbols, consumers can make informed decisions to ensure the safety and longevity of their stored food items.
Additionally, it is worth noting that some plastics may be marked with a number 7, which typically indicates bio-plastics synthesized from plant-based materials. However, not all plastics marked with a 7 are bio-plastics, so it is essential to look for food-handling symbols or explicit "food-grade" or "food-safe" labelling to confirm their suitability for food storage.

Look for food-grade certification
When looking for food-grade certification, there are several reliable ways to identify food-grade plastic containers or buckets. The easiest way is to check the product description, brochure, or website to see if the manufacturer explicitly states that the product is "food grade" or "food safe". If you already have the product, look for an imprinted number or symbol on the base of it. Food-safe plastics are typically numbered 1, 2, 4, or 5, and you may also see symbols such as a cup and fork, indicating the plastic container is suitable for food storage, radiating waves meaning it is microwave-safe, dishes in water meaning it is dishwasher-safe, or a snowflake meaning it is suitable for freezing foods.
Food-grade plastic is different from food-safe plastic as it has been tested to prove there are no dyes or harmful chemicals that could leach into the food inside. This means food-safe does not necessarily equate to being suitable for long-term storage. Food-grade plastic undergoes strict regulation to ensure it is safe for food storage, whereas food-safe plastic simply means it can come into contact with food and water without causing immediate harm to health.
The recycling symbol on the bottom of a plastic container or bucket is also a good indicator of whether it is food grade. Look for the triangular recycling symbol with a number inside. The number will be a Resin Identification Code (RIC) which identifies the type of resin used in the manufacture of the plastic. Numbers 1, 2, 4, and 5 are food-grade plastics, with number 2 being high-density polyethylene (HDPE), one of the most stable and inert forms of plastic, making it the best type of plastic for long-term food storage.
Food-grade plastic containers or buckets are highly versatile, readily available, and affordable. They are perfect for storing large batches of food, such as sauce or grains, as they are airtight, lightweight, and stackable. They are also ideal for the long-term storage of foodstuffs and water, as they won't deteriorate or go off, and will be perfectly safe to consume later.

Check the Resin Identification Code (RIC)
Food-grade plastic containers are designed to store different kinds of food, liquid, or chemicals and are highly versatile, readily available, and affordable. They do not contain recycled plastic products, dyes, or other similar chemicals to ensure consumer safety.
Food-grade plastic containers are typically marked with a cup and fork symbol, indicating that they are suitable for storing food. Alongside this symbol, you may also find a small triangle with a Resin Identification Code (RIC).
The RIC is a number used to identify the type of resin used in the manufacture of the plastic. The numbers 1, 2, 4, and 5 are food-safe. Number 2, for example, indicates that the plastic is made from high-density polyethylene (HDPE), a popular choice for food and beverage shipments due to its stability and inertness. Number 4 denotes low-density polyethylene, while number 5 indicates polypropylene.
Food-grade plastic containers may also display additional symbols related to specific uses. For instance, a symbol of radiating waves or squiggly lines indicates that the container is microwave-safe, while a symbol of dishes in water means it is dishwasher-safe. A snowflake symbol signifies that the container is suitable for freezing.
When buying plastic containers, it is important to read the label or manufacturing details of the product. If you are buying new buckets, this information is typically provided in the product description. Additionally, food-grade plastic containers may be labelled as "FDA approved", "USDA approved", "food grade", or "food safe".

Check for food-handling symbols
Food-handling symbols are a standardised system of symbols that indicates whether a plastic container is safe to use for food storage. These symbols are usually accompanied by a Resin Identification Code (RIC) or a recycling symbol. The RIC is a number used to identify the type of resin used in the manufacture of the plastic. Numbers 1, 2, 4, and 5 are food-safe.
The main symbol for food-grade plastic is a cup and fork symbol. This symbol indicates that a plastic container is suitable for storing food. The cup has a chalice shape, while the fork has three prongs.
Other food-handling symbols include:
- Radiating waves or squiggly lines: This symbol indicates that the container is microwave-safe.
- Dishes in water: This symbol means that the container is dishwasher-safe.
- Snowflake: This symbol means that the plastic container is suitable for freezing foods in.
It is important to note that not all plastic containers with these symbols are food-grade. It is also crucial to check the RIC or recycling symbol to ensure that the container is made with food-safe plastic.
When buying new containers, it is always good to check the label as it should indicate if the plastic is food-grade. If the manufacturer does not explicitly state that the container is food-grade or safe for food storage, it is safer to assume that it is not.
