Thermal Bag Keltin 5.5 L – insulated lunch cooler for food and drinks

The Keltin 5.5 L thermal bag is an insulated lunch cooler designed to maintain the temperature of food and drinks during short-term transport. With a compact form factor and low weight, this portable cooler fits a packed lunch, snacks, a small meal container and a bottle, making it suitable for daily commuting, picnics or quick grocery runs. The bag combines an inner insulating layer and an outer protective shell to provide basic thermal protection and help preserve freshness for several hours.

Advantages

The insulated construction reduces heat transfer to slow cooling or warming of contents, while the compact 5.5 L volume balances capacity with portability. The lightweight design and simple closure make the Keltin thermal bag easy to carry and store. The wipeable inner lining facilitates cleaning and prevents liquid absorption, and the durable outer fabric protects against minor impacts and dirt during everyday use.

• Packed lunches for work or school

How to use

Place food and beverages inside the bag, taking care to pack hot items in suitable sealed containers and cold items with an ice pack if extended cooling is required. Close the zipper fully to maximize thermal retention. For best results, pre-chill the bag briefly by inserting a cold pack before loading refrigerated items, or warm it slightly with a warm pack for hot food. Avoid overfilling to preserve insulation performance and to allow the zipper to close securely.

Usage recommendations

Clean the interior with a damp cloth and mild detergent after each use and allow to dry fully before storing. Do not place the bag directly on open flames or in an oven; avoid machine washing unless the product care label explicitly permits it. Use leak-proof containers for liquids to prevent spills and extend the service life of the lining.
