Using ultrasonic or thermal method to weld PE foam liners together with breathable membranes, you get PE foam induction liners, which has HDPE membrane on both sides, and with two thicknesses available: 1.2mm and 2mm. When the cap is screwed in, it exercises a pressure on the foam induction liner, so the gas can be quickly discharged at the hole of the cap.
The easy-to-install PE foam induction liners have simplified designs and excellent chemical resistance and surfactant resistance capabilities, as well as good air permeability, and are suitable for small volume packaging (less than 5L), thus, they are widely used in industrial chemical packaging. Foam liners include physical foaming and chemical foaming. Physical foaming liners are mainly used in Food packaging, while chemical foaming liners in chemical packaging. Product size and functions can be customized to client needs.
