Choosing a foldable shopping bag: how to find a practical bag for every shop

A foldable shopping bag may seem simple, but not every model is suitable for everyday use. A bag can be lightweight yet awkward to carry. A large capacity also does not always indicate how well the bag holds its shape, how comfortable it is to carry or how much space it takes up when folded.

Pay particular attention to these three common pitfalls:

  • The stated capacity only applies when the bag is unfolded. For example, a 35-litre bag may offer a capacity of 20 litres in its standard form.
  • Thin shoulder straps can become uncomfortable. Narrow straps put pressure on your shoulder more quickly, especially when the bag is full.
  • ‘Water-repellent’ does not mean waterproof. According to the product description, a fabric may resist splashes, stains or moisture without the seams being able to withstand prolonged rain.

Comparing capacity, carrying style and packability in advance can help you avoid a disappointing purchase. Below are the key points to consider for shopping, travel and everyday use in the Netherlands.

What should you look for in a foldable shopping bag?

1. Choose the capacity based on how you will use it

For a few everyday groceries, a 16-litre shopping bag is often sufficient. Think bread, fruit, packaged goods or a packed lunch. A model with this capacity is usually lightweight and easy to carry in a coat pocket, handbag or pannier.

For a larger supermarket shop or household items, a 35-litre shopping bag is more practical. However, check whether this refers to the maximum unfolded capacity. According to the product information, the Beneunder LC168 has a standard capacity of 20 litres and an unfolded capacity of 35 litres. This difference is important if you use the bag every day.

Pay attention to the base dimensions, too. A wide, stable base helps with larger packages, while a narrower bag is easier to carry close to your body.

2. Compare weight with carrying comfort

A lightweight shopping bag is useful when you often carry it with you without using it straight away. According to the product specifications, the Beneunder GP155 weighs approximately 64 grams. The bag has a capacity of 16 litres and folds into a pouch measuring approximately 5 by 5.3 inches.

A slightly heavier foldable tote bag may offer more structure, compartments or a larger capacity. The Beneunder LC168 weighs approximately 220 grams. That is still relatively light for a bag that can be expanded to hold up to 35 litres.

As well as weight, consider:

  • the width and length of the shoulder straps;
  • whether the bag can be carried by hand or over the shoulder;
  • how the weight is distributed;
  • the maximum load stated by the manufacturer.

According to Beneunder’s product information, the shoulder straps on the GP155 and LC168 have been widened. This may improve carrying comfort, but how much weight remains comfortable also depends on the contents and your personal preference.

3. Check the material and care requirements

A reusable shopping bag should fit in with your cleaning routine. According to the product description, the GP155 has a smooth, soft fabric and should be cleaned with a damp cloth and air-dried. Machine washing and direct heat are not recommended.

According to the product information, the LC168 uses a lightweight fabric that is said to resist wear, oil, stains and water. These are properties stated in the brand’s product description; they should not be interpreted as a guarantee that the bag is completely waterproof or indestructible.

Always check:

  • whether the bag is machine washable;
  • whether the base has additional reinforcement;
  • whether the zips and seams are protected;
  • how the bag folds away;
  • whether the bag can dry properly after being used when wet.

For cyclists and travellers, a water-repellent shopping bag is useful in light rain or in the event of spills. For prolonged exposure to rain, a separate rain cover or waterproof packaging is a more sensible choice.

Bag or trolley: which carrying style suits you?

A foldable shoulder bag is compact and flexible. You do not need a frame or wheels, and it is easy to use on stairs, in shopping streets or on public transport. With heavy shopping, however, the entire weight rests on your arm or shoulder.

A foldable shopping trolley transfers the weight to wheels. This can be practical for larger shops, household tasks or longer distances. With a trolley, check the folded dimensions, handle, wheel type and stated load capacity.

A stair-climbing shopping trolley may be worth considering for homes without a lift. However, the name alone does not tell you how the wheel mechanism works or what weight is safe. Check the product specifications and instructions on the product page for this information. Also consider the trolley’s width: a compact model is easier to manoeuvre in narrow entrances, but may offer less space.

Frequently asked questions about foldable shopping bags

How many litres does a standard shopping bag need?

For small shops, 10 to 16 litres is often practical. If you want to carry several products or items of clothing, it is better to look at 20 to 35 litres. Always check whether the stated capacity refers to the standard or unfolded capacity.

How do you clean a foldable shopping bag?

Follow the manufacturer’s care instructions. For the Beneunder models mentioned, cleaning with a damp cloth and air-drying are recommended. Do not use a washing machine, bleach or direct high heat if these are not recommended.

Is a shopping trolley more convenient than a shoulder bag?

It depends on the route and the weight. A shoulder bag is lighter and easier to store. A trolley may be more suitable for larger shops, but requires more space when stored and in use. For stairs, you should also carefully check the wheel mechanism and maximum load.
