Yes. The heat-sealable VCI polyethylene allows you to cut tubing to your exact length requirements on-site and seal both ends using a standard impulse sealer or heat-sealing equipment, creating custom bags for different part sizes without excess material waste.
VCI polyethylene provides active corrosion inhibition for 2+ years under normal storage conditions. Protection duration depends on storage temperature, humidity, and whether the bag remains sealed. Proper heat-sealing maximizes protective effectiveness.
VCI polyethylene tubing meets corrosion prevention requirements for domestic and international shipping, including MIL-B-121H and similar military specifications. Verify specific compliance requirements with your customer or regulatory body for your application.
4 mil provides superior puncture resistance, tear strength, and durability during handling, stacking, and transport while maintaining the active VCI corrosion-inhibiting properties, reducing damage claims and product loss in high-volume shipping operations.
