Isothermal envelope 400x400

📦 Insulated envelope 400×400 mm – a compact solution for cooled shipments!

Do you need a smaller, but effective packaging for transporting temperature-sensitive products? Insulated envelope 400×400 mm is an ideal choice for companies that want to ensure the freshness and safety of small products. Thanks to its compact format, it is great for shipping individual portions of food, medicine or cosmetics. The layer of metalized foil and bubble wrap create a effective thermal barrier, and the adhesive strip allows for quick and tight sealing of the envelope.

🌡️ What is a cold supply chain?

The cold supply chain is a process where a product maintains a low temperature from the moment of packaging until it is delivered to the customer. It is essential in industries such as food, pharmaceutical, and cosmetics. The 400×400 mm thermal envelope helps to maintain the cooling chain during the final stage of transport, even without refrigeration.
