Cooling bags / insulation bags

Insulated bags for refrigerated shipping up to 24-72 hours

Cooled Solutions supplies high-quality insulation bags for companies looking to safely ship temperature-sensitive products. From meat and fish to meal boxes and pharmaceuticals - with the right combination of insulation and gel packs, your shipment will stay within the desired temperature during transport.

Our refrigerated bags are used daily in food, pharma and e-commerce logistics and are suitable for daily deliveries of up to about 48 hours. For longer transit times, 6-layer insulation bags are available, depending on application and conditions.

Compared to traditional EPS boxes (Styrofoam), insulation bags take up less space, are more efficient to use and often more economical to transport.

✔ Suitable for refrigerated shipping within food and pharma

Efficient alternative to EPS boxes (polystyrene foam)

✔ Less storage space and lower transport costs

4-layer cooling bags

What is an insulation bag?

An insulation bag is a flexible refrigerated packaging for chilled shipping of temperature-sensitive products. Thanks to multiple layers, such as bubble wrap and reflective film, the contents remain at temperature for longer. Combined with gel packs, it creates an efficient solution for everyday use.

When do you use insulation bags?

Ideal for shipping meat, fish, meals and other chilled products. A 4-layer bag is suitable for standard shipments, while a 6-layer variant offers extra protection in case of heat or longer transport time.

How do insulation bags work?

The layers reflect heat and reduce temperature loss. Combined with gel packs, the contents remain cool for a long time. For optimal performance, compact filling is important: the less air, the better the result.

Comparison of 6-layer and 4-layer insulating bags

The graph shows the temperature progression of Cooled Solutions' 6-layer and 4-layer insulation bags, both applied with a 400-gram gel pack, at a constant ambient temperature of 25°C over a 48-hour period.

Test results thermal bags

 - 6-layer insulation bag - maximum insulation performance

The 6-layer variant stands out for its excellent thermal insulation value.

  • Keeps the temperature to well over 26 hours below 0°C

  • Remains until 48 hours below 8°C

  • This version is mainly used in the summer. Then there are higher outdoor temperatures that need extra protection.

 - 4-layer insulation bag - efficient standard solution

The 4-layer version offers solid performance at a more compact size.

  • Holds contents to approximately 15 hours below 0°C

  • Remains average to 36 hours below 8°C

  • This cooling bag is frequently used during the spring, autumn and winter months, when environmental conditions are less extreme.

Note: For best results, the fuller the bag of frozen products, the better the cooling performance. Limit empty space as much as possible.

Insulation value of insulation bags

Our insulation bags are composed of multiple layers, including bubble film and reflective metal foils. This combination ensures that heat from outside is blocked and cold inside is retained for longer. In practice, this results in a stable temperature during transport, even under varying conditions.

Which variant do you need?

  • 4-layer insulation bag
    Suitable for shipments up to approximately 24-48 hours. Ideal for standard deliveries and cooler conditions.
  • 6-layer insulation bag
    Suitable for shipments of up to approximately 48-72 hours. Perfect for hot days or longer transport times.

Why better than EPS (Styrofoam) boxes?

  • Often better insulation performance in practice
  • Less volume → lower shipping costs
  • Lighter and more efficient in storage
  • No large waste streams like Styrofoam

Applications of cooling bags / insulation bags

Refrigerated bags and insulation bags are widely used for chilled shipping of temperature-sensitive products. Think of online meals, meat, fish, dairy and AGF. A well-insulated chilled shipping bag helps products arrive fresh and safe at the customer's doorstep.

Online meals

For meal-prep companies and meal boxes, cooler bags are a practical solution. Fresh ingredients and ready-made meals stay at temperature for longer during transport, even if the recipient does not accept the package directly.

Meat and fish

Insulating bags are also great for fresh meat, fish and other temperature-sensitive products. They help keep the cold chain intact from shipper to receiver.

Dairy and AGF

Dairy products, fruit, vegetables and other fresh produce can be reliably shipped chilled using an insulated bag with bubble wrap. Combined with gel packs, this creates a complete solution for chilled shipping.

Refrigerated bags are available in various sizes, making them suitable for both small shipments and larger packages. Combined with cooling elements, they offer a reliable solution for almost any refrigerated shipment.

Durability and materials

In addition to performance, sustainability also plays an important role. Our insulation bags are produced from high-quality materials and are also available in a variant with 95% recycled material. This allows you to choose a solution that better suits companies that want to pack more sustainably.

An insulation bag takes up much less space after use than a traditional EPS box. This makes this form of refrigerated packaging not only more practical for the recipient, but also more attractive from a waste disposal and convenience point of view.

  • Available in variants with 95% recycled material
  • Less volume than EPS boxes
  • Easy to throw away after use
  • Suitable as one-way shipping packaging

Ease of use for sender and receiver

Our cooling bags and insulation bags are designed for practical everyday use. They are delivered flat, take up little storage space and are quick to process. Combined with gel packs and a cardboard box, they create efficient packaging for refrigerated shipping.

For the sender

  • Supplied flat and compact
  • Little storage space required
  • Quick to pack
  • Easy to combine with gel packs and boxes

For the recipient

  • Light and handy package
  • No fragile Styrofoam
  • Less waste volume
  • Easy to throw away after use

Insulated bag + Standard box combination

Placing our insulation bags in a standard cardboard box instantly creates a 'cooler' that keeps your products well chilled.
