LocknLock Food Storage Containers: A Complete Buying Guide

By the Joybuy Product Recommendation Officer, 20 July 2026

Proper food storage is crucial for preserving freshness, keeping your kitchen organised, and transporting meals safely. We've all been there: a pre-prepared lunch leaks in your bag, vegetables in the fridge wilt too quickly, or the smell of onions spreads throughout the entire fridge. LocknLock food storage containers have established themselves as a practical solution to these everyday challenges.

This article serves as a guide. It explains the key features of the various LocknLock models and presents a curated selection to help you choose the right container for your needs.

What to Look for When Choosing Food Storage Containers

To find the right storage solution, several functional aspects should be considered. The following points will help you tailor your choice to your specific needs.

1. Material: Glass or Plastic?

The choice of material largely depends on its intended use.

• Glass Food Storage Containers: Containers made of borosilicate glass are particularly temperature-resistant. An oven-safe glass dish with a lid can go directly from the fridge to the oven (without the lid) or microwave. Glass is also non-porous, stain-resistant, and odour-resistant, making it ideal for storing strongly coloured or aromatic foods like tomato sauce or curry.
• Plastic Storage Containers: Modern plastic containers from LocknLock are BPA-free and therefore safe for food contact. Their main advantages are their light weight and high durability. This makes them a great choice for on-the-go use, for example, as a lunch box for work or for an outdoor picnic.

2. Seal and Leak-Proof Design

A central feature of LocknLock is its patented locking system with a four-sided locking mechanism and a silicone seal. This system ensures the containers are both airtight and watertight. A leak-proof lunch box is essential if you want to transport soups, sauces, or salads with dressing. The seal also prevents the transfer of odours in the fridge and protects food from drying out.

3. Functionality and Shape

Consider what you will primarily use the containers for.

• Meal Prep Containers: For preparing meals in advance, containers that are suitable for use as both freezer-safe containers and for the microwave are practical. Models with dividers help to keep components of a meal separate.
• Stackability: To save space in your kitchen cupboards or fridge, stackable Lock & Lock models are a smart choice. Many series are designed to be modular, allowing containers of different sizes to be stacked securely on top of each other.

Based on the criteria above, we have put together a selection of LocknLock products that are suitable for a variety of applications.

Frequently Asked Questions (FAQ)

1. Are LocknLock containers microwave-safe?

Yes, most LocknLock plastic and glass containers are suitable for use in the microwave. However, it is important to remove the lid completely before heating, as pressure can build up from the steam. For plastic containers, you should avoid heating foods high in fat, oil, or sugar, as this can cause warping.

2. Are LocknLock plastic containers safe?

LocknLock uses materials for its plastic storage containers that are BPA-free. BPA (Bisphenol A) is a chemical found in some plastics. BPA-free products are considered a safe choice for food storage.

3. What is the best way to clean LocknLock containers?

All components of LocknLock containers are generally dishwasher-safe. For a particularly thorough cleaning, the silicone seal can be removed from the lid and cleaned separately. This ensures that no moisture or residue collects underneath, maintaining the container's leak-proof seal.
