F217-3 Liner - is a three layer co-extruded seal: two solid polyethylene surfaces cover a central layer of foamed poly-ethylene with closed cells. This structure is a single polymeric unit which cannot delaminate. • Construction: solid PE-EVA / foamed EPE / solid PE-EVA.• Tri Seal F 217-3 is developed especially for use In aggressive media where normal LDPE would be subjected to stresscracking.• The foamed center core provides the resiliency needed for sealing and the solid facings prevent evaporation and product penetration.

F217-3 seals can be used for:

- alcoholic and non-alcoholic beverages- dietary supplements - food products, oils- cosmetics and pharmaceuticals

Properties:

• Mechanically strong• Excellent chemical resistance• Good machineability• Seals both glass and plastic bottles/jars• Seals with pressure, no heat needed to seal• Good compressibility• No lamination, no glue• No discoloration• No absorption• Ideal application and removal torque• No dusting: foam particles cannot come loose• Non-toxic and free of odours and taste
