How to Choose the Right Food Storage Containers

Choosing the right food storage containers can make your kitchen more organised and everyday food storage more convenient. But which material is best for your needs?

Plastic, stainless steel, glass and silicone each have their own advantages. In this guide, we'll compare their uses and limitations to help you choose the right containers for your kitchen.

1. Plastic Food Storage Containers

Plastic containers are lightweight, affordable and convenient for everyday food storage.

Temperature and Appliance Use

• Refrigerator: Generally suitable for compatible products.
• Freezer: Use only if labelled freezer-safe, as some plastics may become brittle and crack.
• Dishwasher: Some PP and Tritan containers are dishwasher-safe, but repeated high-temperature washing may accelerate ageing. PET containers are generally not recommended for dishwasher use unless approved by the manufacturer.
• Microwave: Only use containers labelled microwave-safe. PET and Tritan containers are generally not recommended for microwave heating unless specifically approved.
• Oven and steam oven: Generally unsuitable unless specifically designed for these applications.

For practical reference, this guide uses 0–80°C (32–176°F) for PP and Tritan, and 5–50°C (41–122°F) for PET. These are conservative reference ranges, not universal safety limits. Always follow the temperature limits stated for the product.

Best For

Everyday organisation of suitable fruit, vegetables, cereals, dried fruit and other ingredients at room temperature or in the refrigerator.

Things to Consider

Plastic is convenient, but its heat resistance and durability vary depending on the material and product.

2. Stainless Steel Food Storage Containers

Stainless steel is durable, corrosion-resistant and suitable for repeated everyday use. Common food-contact grades include 18/8 and 18/10 stainless steel.

Temperature and Appliance Use

• Refrigerator and freezer: Many products are suitable; check the lids and seals.
• Dishwasher: Many products are dishwasher-safe.
• Microwave: Generally unsuitable for conventional microwave ovens.
• Conventional oven and steam oven: Suitable only when the complete product is designed for the intended appliance.

Stainless steel itself can withstand high temperatures, but plastic lids, silicone seals and locking clips may have lower temperature limits.

Best For

Raw meat, cooked meat and prepared foods that require refrigeration or freezing, provided the container is suitable for the intended conditions.

Advantages

Durable, reusable and resistant to breakage.

Things to Consider

Stainless steel containers generally cost more than basic plastic alternatives. They are also opaque, so you cannot see the contents without opening the lid.

3. Glass Food Storage Containers

Glass is transparent and non-porous, making it an excellent choice for organised pantry storage. It allows you to identify ingredients quickly and see how much remains.

Two common types are soda-lime glass and borosilicate glass.

Temperature and Appliance Use

• Refrigerator: Many glass containers are suitable.
• Freezer: Use only products labelled freezer-safe.
• Dishwasher: Suitability depends on the product. Printed designs, lids and seals may require special care.
• Microwave, conventional oven and steam oven: Use only when the product is specifically designed for the intended appliance.

For practical reference, this guide uses 5–60°C (41–140°F) for soda-lime glass and 5–100°C (41–212°F) for borosilicate glass. These are general reference ranges, not universal product specifications.

Borosilicate glass generally offers better resistance to thermal shock, but not every product is suitable for heating. Avoid sudden temperature changes and always follow the manufacturer's instructions.

Best For

Dried fruit, nuts, biscuits, grains, cereals, snacks and other dry pantry ingredients. Glass is also a popular choice for food containers and meal prep, particularly when made from heat-resistant glass and specifically designed for microwave or oven use.

Advantages

Transparent, easy to view and gives your kitchen a clean, organised appearance.

Things to Consider

Glass can break if dropped or knocked. Handle it carefully, particularly in family kitchens with young children.

4. Silicone Food Storage Containers

Food-grade silicone is flexible, lightweight and useful for space-saving storage.

Temperature and Appliance Use

• Refrigerator and freezer: Many products are suitable.
• Dishwasher: Many products are dishwasher-safe.
• Microwave: Only use products labelled microwave-safe.
• Conventional oven and steam oven: Suitable only when specifically approved for these applications.

Some silicone products are designed for temperatures ranging from approximately -5°C to 220°C (23–428°F). This is a general reference range, not a universal limit. The suitability of the complete product, including lids, zips and valves, depends on its individual components.

Best For

Flexible food storage, freezer organisation and kitchens where space is limited.

Advantages

Some reusable silicone bags can be folded or flattened when empty. Their flexible construction also reduces the risk of breakage if dropped.

Things to Consider

Silicone storage bags are not automatically suitable for every cooking appliance. Always check the manufacturer's instructions.

Food Storage Containers: A Quick Comparison

Always check the manufacturer's instructions for temperature limits, dishwasher use and appliance compatibility.

Which Material Is Best for Different Foods?

Raw Meat, Cooked Meat and Prepared Foods — Stainless Steel

Stainless steel is a durable option for foods that require refrigeration or freezing. Keep raw meat separate from ready-to-eat foods and clean containers thoroughly between uses.

Fruit and Vegetables — Plastic or Silicone

These materials offer convenient, lightweight storage for suitable produce, including cucumbers, sweetcorn, lemons and oranges.

Dried Fruit, Nuts, Biscuits and Grains — Glass

Glass jars are ideal for pantry organisation. Their transparency makes ingredients easy to identify, while well-fitting lids help protect dry foods from moisture and household pests.

Our Kitchen Recommendations

In everyday use, many types of food can be stored in more than one material. Everyone has their own habits and preferences. Some people prefer not to use glass because it can break easily, while others prefer to avoid plastic due to personal concerns. Both choices are understandable, and we believe everyone should be free to choose what works best for them.

Our recommendations simply reflect our own experience in the kitchen. For example, we tend to prefer glass for dried foods because it offers clear visibility and a neat pantry appearance. For fruit and vegetables, we often recommend plastic or silicone because their lightweight and flexible designs are more practical for larger or irregularly shaped produce.

Ultimately, these are suggestions rather than absolute rules. We hope they give you a useful starting point when choosing food storage containers, while leaving room for your own preferences.

Important Things to Remember

The temperature ranges in this guide are practical reference points, not universal guarantees of food-contact safety. A material's melting point is not the same as its recommended working temperature.

Food storage products may also combine several materials. For example, a stainless steel container may have a plastic lid, silicone seal or plastic locking clips. Printed designs on glass may also require special care.

Always follow the manufacturer's instructions for the complete product.
