Identifying food-grade plastic buckets

There are many uses for a plastic bucket with a lid, ranging from storing food, to storing children's garden toys, but how do you know which bucket is safe to use for food storage? We have come up with a helping guide to assist your judgment.


Food grade plastic

It is fairly obvious that the bucket and spade that you buy from the brightly coloured beach kiosk whilst on holiday are not intended for the safe and hygienic containment of food. But when faced with a variety of plastic buckets with lid in your local supermarket or wholesaler, it is vital that you understand what the various symbols mean in order to enable you to purchase the most appropriate container.

 

Food-grade plastic is plastic that has been tested to the rigorous standards set by the Food Standards Agency [1] to ensure that no chemicals within the plastic will leach into the contents, rendering them unsafe to eat.

 

There are many ways to identify food-safe packaging. The first is to check the labelling. Often, a plastic bucket with a lid that is designed to store or transport food will have a picture on its label depicting this scenario. The label may also make reference to the container being safe to microwave, freeze or clean in a dishwasher, which suggests that it is suitable for food heating, food storage, and container cleaning purposes.

 

The best way to ensure that the product that you buy is truly food safe, however, is to look for the symbols that are printed onto its base. All plastic products will be stamped with a Resin Identification Code, which is a number between 1 and 7 that is printed into the centre of three arrows which form a triangle shape.

 

Typically, the numbers 1, 2, 4 and 5 are designated food safe and are the preferred choice of manufacturers and retailers whose food or drink products will be in direct contact with the plastic packaging. Often, plastics stamped with the number 7 will be made from plant-based bioplastics, which are also food safe, however, this is not always the case.

 

Products that are stamped with 3 or 6 may be food safe, but unless further labelling confirms this to be the case, you should assume that food products should not be stored in direct contact with the product.

 

Other symbols that will identify food-safe plastic packaging include a cup and fork symbol, a radiating waves symbol, a symbol depicting dishes in water, or a snowflake. Where a plastic container features a number of these symbols, it is a good indicator that it is a versatile food-safe container that will fulfil a number of roles, such as storage of fresh food, reheating of food, or freezing food for later consumption.

 

Choosing a food-grade plastic bucket with lid

 Once you have checked the labelling and symbols to confirm that a plastic bucket is food safe, you will need to make some further decisions to ensure that the product you buy will satisfy your needs. This includes ensuring that you select a product of a size that is commensurate with the items that you will wish to store.

 

Small, rectangular or square lidded buckets are ideal for the catering industry which may wish to prepare individual portions for re-heating by customers later on. These containers have the added benefit that they can be washed and reused on numerous occasions by the customer who may choose to use them for storing leftovers or batch cooking.

 

Round containers are ideal for transporting soups and other liquids. They are also popular with domestic customers who will use them for storing dry ingredients, such as rice, lentils, pasta and cereals.

 

Typically, large containers lend themselves well to the catering or agricultural industries, while smaller products will be preferred by domestic customers who have limited space for stacking or storing large quantities of food and beverage products.

 

Play it safe

If the plastic bucket with lid that you believe to be well suited to your intended purpose does not state that it is food safe, nor bear any of the symbols that are detailed above, you should assume that it is not safe for direct contact with food and resist using it for this purpose. This is due to the very real harm that could occur should anyone ingest harmful chemicals or plastic particulates.
