These temperature controlled pouches provide great protection for a smaller number of products that require thermal protection for a shorter length of time. Each pouch has an easy 5mm lip with peel and seal strip for secure enclosure once products are placed inside. Their metallised polyester outer is water-resistant and protects against other harmful factors, whilst maintaining a consistent internal temperature throughout transit and delivery stages. There are a range of different sizes to choose from to allow you to find the right sized mailer for your packing operations. These insulated pouches are great for smaller, slimmer products that need lightweight, insulated packaging to get them to their destination at the same temperature they left the warehouse in.
