The seamless vacuum-liners have a contoured lip that snaps over an open-head drum's top bead, preventing leakage between the liner and drum/pail wall. Anti-stat products reduce static build-up by dissipating static charges away from potentially flammable products and static sensitive applications such as paints, volatile materials and fine powders. Liner inserts provide protection against drum corrosion and reduce drum cleaning and reconditioning costs. After use, simply lift out the liner – the drum/pail is clean and ready for re-use!
