Synthetic two-piece induction seal products
A two-piece induction seal for use in creating clean, safe, and secure inner seals on containers having a monolayer plastic formed from synthetic fibers with stable pore dimensions for fluid permeability while retaining dimensional stability for compression. An inductive innerseal membrane is provided having a first side and a second side thereof, with an adhesive layer at the first side of the membrane. The second side of the membrane is detachably bound to the synthetic material with a wax layer. The synthetic material is further suitable for absorbing substantially all of said wax layer when said wax layer is in liquid form.
