10 Tips for Extending the Shelf Life of Food with Glass Food Boxes

Food waste is a big problem both for the wallet and the environment. Glass food boxes are an effective way to extend the shelf life of food and reduce wastage. Here are our top 10 tips to keep food fresher for longer.

1. Use Sealing Lid With Vacuum Function

A tightly sealing lid with vacuum reduces the exposure of food to air and decreases the risk of food spoilage. See our range of glass food containers with high-quality vacuum function lids.

2. Label Your Lunch Boxes

Write the date on the boxes so you know how long the food has been stored. This will help you use it before it gets old. That's why we have a date function on all our food boxes that makes it easier to remember when you set the food.

3. Keep Food Cold

Refrigerate or freeze food immediately after cooking to prevent bacteria from growing. Glass food boxes can withstand both refrigeration and freezing without problems.

4. Divide Large Portions

Store food in smaller portions to more easily reheat only what you need, reducing the risk of leftovers going bad.

5. Use Absorbent Paper

Place a layer of absorbent paper under fruits and vegetables to keep them dry and fresh for longer.

6. Store Sauces Separately

If possible, store sauces and dressings separately to avoid food becoming soggy and losing its texture.

7. Freeze Leftovers in Time

Freeze leftovers as soon as possible after the meal to preserve flavor and quality.

8. Avoid Overfilling the Boxes

Leave some space for the box to close properly, preventing air from entering.

9. Use Glass for Strong Flavors

Glass does not absorb odors, making it perfect for storing foods with strong flavors such as garlic and curry.

10. Clean the Drawers Thoroughly

Wash glass food containers thoroughly after each use to prevent bacteria buildup. Read more about this in our guide to cleaning glass food containers.
