The insulated mailer has thermal insulation materials. This material has a relatively low thermal conductivity, which blocks the contact between the frozen food and the air, so that the temperature inside is concentrated in the bag and cannot be directly emitted. This can keep the temperature inside the bag for more than 24 hours. To achieve the purpose of heat preservation.

Heat preservation and cold preservation is the most basic function of the insulated mailer. It is a special bag with short-term heat preservation effect. It can keep cold/heat. The product material is pearl cotton + aluminum foil tin foil, which can provide good heat insulation effect.

Landy insulated envelope must have superior impact resistance, not easily broken when pressed or impacted, and will not leave scratches
