Constitution and Functioning

The ONE DAY isothermal bag is a metallized isothermal bag composed of a multi-layer structure (metallized PET film – expanded PE foam – white inner PE film certified for food contact according to the 1935/2004/CE and 10/2011/UE regulations) in which a thin layer of refrigerant is inserted, evenly distributed on the 2 sides of the bag

This technological innovation considerably increases the isothermal and refrigerating performance of the bag while keeping a light weight.

To take advantage of the great performances, this bag must be previously frozen to load the refrigerant which will then fully diffuse its cold energy during your cold chain.

Instructions of use

isothermal packaging-frozen-COLD&CO
  1. Store your ONE DAY FRESH bag in the freezer (minimum 24h)
  • Use a -18°C freezer for the ONE DAY FRESH bag
  • Use a -30°C freezer for the ONE DAY FREEZE bag
  1. When the walls of the bag are fully rigidified, the ONE DAY isothermal bag is ready to be used
  2. Load the bag with your fresh or frozen goods
  3. Close the bag with the handle
  4. Deliver your goods
  5. Organize return logistics with your customers to reuse your ONE DAY cold diffusion bag


The ONE DAY cold diffuser bag has a simple and ergonomic design.

A large opening allows you to easily slide your fresh and frozen products, especially in cold rooms where operations are carried out with thermal protection gloves.

Order picking operations are optimized with this isothermal bag whose refrigerant is directly integrated into the walls of the bag. As an integral part of the bag, there is no risk of forgetting the coolant! The coolant does not mix with the goods. From an operational point of view, you limit your references of non-merchandise products, since a single reference groups the bag and the coolant.

A reusable refrigerated cooler bag

oneday bag-fresh-freeze-isothermal bag-packaging

The technology of the ONE DAY refrigerated bag is reusable. Like a cold battery, the bag can be refilled as many times as possible in the freezer (only physical or hygienic deterioration of the bag can limit its life span).

Its closing system – an integrated handle with a spike – allows multiple openings/closures. A return and reuse logistics can therefore be set up with this ONE DAY refrigerated isothermal bag.

Eco-responsible manufacturing

The ONE DAY refrigerated cooler bag is a clean polyethylene/polyester bag, 100% recyclable. It is manufactured in a border country in one of our partner factories in a company that cares about its environmental impact:
