When it comes to the storage of bulky materials and foodstuffs, tubs and troughs are often the ideal solution.
Tubs
Using plastic tubs allows you to store large quantities of materials, including foodstuffs and store it in an insect-proof and airtight container, reducing risk of damp and bacterial contamination.
Troughs
Freestanding plastic troughs, or troughs which can be held in steel, moveable trolleys are tough, durable and hygienic products with a variety of uses and they are frequently utilized within food processing and manufacturing, bakeries, the meat industry and catering trades. They are often used as washing and cleaning units for the cleaning of utensils and apparatus as they are very easy to clean and allow water to be drained freely and easily.
What materials?
Stainless steel
Stainless steel does not leach chemicals.
Bacteria are a greater food safety concern than leaching chemicals. You minimize bacteria with tight sealing lids. ...Metal containers with slip-over metal lids seal as well as the best plastic containers.
Do bear in mind that metal containers with plastic lids tend not to seal very well.
Metal containers with slip-over metal lids seal as well as the best plastic containers.
Plastics
Plastic tubs are often less expensive and lightweight as well as being durable. However, not all plastics are safe for use with food;
There are seven types of plastic, usually indicated by a number in a triangle on the container bottom.
1. Polyethylene Terephthalate (PET or PETE)
E.g. Disposable soft drink and water bottles.
2. High Density Polyethylene (HDPE)/
E.g. Liquid detergent bottles, shampoo bottles
3. Polyvinyl Chloride (V or PVC)
E.g. Meat wrap, cooking oil bottles.
4. Low Density Polyethylene (LDPE)
E.g. Clingfilm, sandwich bags
5. Polypropylene (PP)
E.g. Syrup bottles, yogurt tubs,
6. Polystyrene (PS)
E.g. Disposable coffee cups
7. Other (misc.; usually polycarbonate, or PC, but also polylactide, or PLA, plastics made from renewable resources)
E.g. Baby bottles, medical storage containers.
- The best type of plastic for use in long-term food storage is high-density polyethylene (HDPE), which is indicated by the "2" symbol. HDPE is one of the most stable and inert forms of plastic, and all plastic buckets sold specifically for food storage will be made from this material.
- Also take note of any food-handling symbols imprinted on the plastic item. A standardized system of symbols is used on plastics to indicate their appropriate uses around food. A symbol depicting a cup and fork means that the plastic is safe for storing food, and is therefore a food grade container.
Key features to look for in tubs
- Hygienic design: Smooth internal and external walls to ensure easy cleaning and avoid areas where bacteria can be harboured.
- If plastic, made with food safety approved polymers. See above for more guidance on the different kinds of plastic.
- Colour coding: helps to avoid cross-contamination.
- Easy to read measures: Accurate measures inside can help with stock taking and informing staff on how much product is stored / can be added to the container.
- Durability: Investing in containers made from durable materials means you don’t have to replace equipment, but also, there’s lower risk of contamination from bacteria gathering in damaged edges.
- Close fitting lid: to enable materials and foods to be stored in hygienic, airtight conditions.

Key features to look for in troughs
- Plug chains on the outside of the unit: this ensures the user does not have to get wet to drain the trough.
- Hygienic design: Smooth internal and external walls to ensure easy cleaning and avoid areas where bacteria can be harboured.
- If plastic, made with food safety approved polymers. See above for more guidance on the different kinds of plastic.
- Colour coding: helps to avoid cross-contamination.
- Easy to read measures: Accurate measures inside are useful particularly if containers are used for concentrated solutions.
- Durability: Investing in troughs made from durable materials means you don’t have to replace equipment, but also, there’s lower risk of contamination from bacteria gathering in damaged edges.
- Close fitting lid: to enable materials and foods to be stored in hygienic, airtight conditions.
