Product Overview
Our bag-in-bag pouch features a unique inner pocket structure inside the outer pouch. Two separate sealed chambers store different functional substances without direct contact. When users squeeze and rupture the inner compartment, the reaction of the rear cavity releases heat or cold energy, transferring temperature to the front cavity where the facial mask is placed. It achieves instant warming or cooling without blending two materials. The pouch supports hang holes, full-color gravure printing and various high-barrier composite films to meet retail shelf display needs.
