What You'll Learn
Check the bottom of the barrel for markings
When identifying food-grade plastic barrels, it is important to check the bottom of the barrel for markings. This is because food-grade plastic barrels will often have markings that indicate their suitability for storing food. The bottom of the barrel is usually the best place to find these markings, as this is where the manufacturer will typically place important information about the product.
One of the most important markings to look for is the Resin Identification Code (RIC). The RIC is a number used to identify the type of resin used in the manufacture of the plastic. This code is typically found inside a small triangle, which may be located on the bottom of the barrel. The RIC codes most commonly used for foodstuffs are #2, #4, and #5. A #2 code indicates that the plastic is made of high-density polyethylene (HDPE), which is the most common type of plastic used for food-grade barrels. HDPE is considered safe for long-term food storage and is also used for freezer bags, grocery bags, and milk containers.
In addition to the RIC code, food-grade barrels may also have other markings or symbols. One common symbol is a cup and fork, which indicates that the barrel is safe for food storage. Smaller, microwave-safe containers may also have radiating waves stamped on the plastic to indicate their suitability for microwave use. Other symbols may include a snowflake to indicate freezer safety or dishes in water to indicate that the barrel is dishwasher safe.
It is important to note that not all plastic barrels are safe for food use, even if they have food-grade markings. It is always a good idea to check for any signs of previous use, as barrels previously used for non-food items should not be reused for food storage due to the risk of contamination. Additionally, some food-grade markings may not be easily visible, so it may be necessary to clean the barrel or bucket to find the relevant markings.
Overall, checking the bottom of the barrel for markings is an important step in identifying food-grade plastic barrels. By looking for the RIC code and other relevant symbols, you can ensure that the barrel is made of a type of plastic that is safe for food storage.

Identify the Resin Identification Code (RIC)
The Resin Identification Code (RIC) is a marking found at the bottom of a food-grade plastic barrel inside a small triangle. The RIC is a number used to identify the type of resin used in the manufacture of the plastic. The RIC code is usually in the form of an arrow-shaped triangle, which is a code for identifying a specific type of material.
The RIC code is an important marking as it helps identify the type of plastic barrel you are looking at. The RIC is the same as the RIC code of the corresponding material. The RIC number of a food-grade plastic barrel should be readable without any difficulty. It should also be incorporated into the RC. The RIC code is useful when you need to identify food-grade plastic barrels.
The RIC code is a symbol that shows the type of plastic that a barrel is made of. It is most commonly found on barrels that are made of high-density polyethylene (HDPE), a type of plastic that is naturally UV resistant. HDPE is also used in food-grade barrels (containers) and is the standard packaging material. It can be used in freezer bags, grocery bags, milk containers, and condiment squeeze bottles.
The RIC code is also important for recycling. The RIC system was designed to make it easier for workers in materials recovery and recycling facilities to sort and separate items according to their resin type. Plastics must be recycled separately, with other like materials, to preserve the value of the recycled material and enable its reuse.

Understand the meaning of the symbols
Food grade plastic barrels have distinct symbols that help identify their suitability for storing food. The main symbol for food-grade plastic is a cup and a fork, with the cup having a chalice shape and the fork having three prongs. This symbol indicates that the container is safe for storing food.
In addition to this primary symbol, food-grade plastic barrels often display a Resin Identification Code (RIC) enclosed within a small triangle. The RIC is a number that identifies the type of resin used in the manufacture of the plastic. Common RIC codes for food-grade barrels include #2, #4, and #5. A #2 code indicates the barrel is made of high-density polyethylene (HDPE), #4 denotes low-density polyethylene, and #5 signifies polypropylene. HDPE is a UV-resistant plastic commonly used for food-grade barrels, freezer bags, grocery bags, and milk containers.
The colour of the RIC code can also provide information about the barrel's suitability for food storage. A blue RIC code generally indicates food-grade quality, while a green code suggests the presence of recycled plastic, which may be more likely to contain toxic materials. Additionally, a yellow RIC code likely indicates food-grade plastic.
Other symbols found on food-grade plastic containers include radiating waves, indicating that the container is microwave-safe, a snowflake symbol suggesting freezer-safe properties, and dishes in water, denoting dishwasher safety. These symbols provide important information about the functionality and suitability of the plastic barrels for food storage.

Confirm it's made from food-grade plastic
Confirming that a plastic barrel is made from food-grade plastic is crucial to ensure the safe storage of foodstuffs. Here are some detailed steps to help you identify if a plastic barrel is indeed food grade:
Firstly, it's important to understand that not all plastic barrels are safe for food use. Food-grade plastic barrels have been specifically approved by the Food and Drug Administration (FDA) for food packaging and long-term storage. These barrels are designed to be airtight and insect-proof, ensuring the stored food remains safe to consume.
Now, to identify if a plastic barrel is food grade, you'll need to inspect it for specific markings and symbols:
- Flip the barrel upside down and look for markings on the bottom: The label indicating the type of plastic is usually found here. Clean the barrel if it's dirty to better see the markings.
- Locate the Resin Identification Code (RIC): The RIC is often found inside a small triangle and is a crucial marking. It is a number that identifies the type of resin used in the manufacture of the plastic. Commonly, foodstuffs are shipped in barrels with RIC codes of #2, #4, and #5.
- Identify the type of plastic:
- #2 indicates High-Density Polyethylene (HDPE), which is the most common food-grade plastic. It is used for freezer bags, grocery bags, milk containers, and food buckets.
- #4 stands for Low-Density Polyethylene (LDPE), which is used for bread bags, frozen food bags, squeezable mustard and honey bottles, among other things.
- #5 means the barrel is made of Polypropylene (PP), which is used for ketchup, syrup, and yogurt containers.
- Look for additional symbols: Food-grade barrels might also have symbols like a cup and fork, indicating food storage. Other symbols include radiating waves for microwave safety and a snowflake for freezer safety.
- Check for "Food Grade" markings: Some barrels will explicitly state "Food Grade" or "Food Safe." If you're buying a new barrel, it may have a sticker indicating its food safety.
- Inquire with the manufacturer: If you're unsure, don't hesitate to contact the manufacturer or distributor to confirm if the barrel is food grade.
Remember, while these markings and symbols are essential indicators, always exercise caution and prioritize food safety. When in doubt, it's better to replace the barrel or use alternative storage methods like mylar bags for dry goods.

Check for any previous contents
When purchasing a plastic barrel, it is important to check for any previous contents. This is because the previous contents of a plastic barrel can determine whether it is still food grade or not. For example, a barrel that previously contained a drink concentrate may still smell of its previous contents, even after disinfection.
Some sellers may provide labels or descriptions of the barrel's previous contents. For instance, a seller might disclose that a barrel previously contained vinegar, propylene glycol, or water-soluble substances. In other cases, you may need to rely on your senses, such as smell, to determine if there are any residual traces of the previous contents.
It is important to thoroughly clean and disinfect a used barrel before using it for food storage, especially if it previously contained non-food-grade substances. A common method for disinfecting plastic barrels is to use a bleach and water solution, or a 10% bleach solution for more challenging compounds.
It is also crucial to consider the trustworthiness of the seller when purchasing a used plastic barrel. Verifying the seller's claims about the previous contents and ensuring they have a good reputation can help ensure the barrel is safe for food storage.
