Profile: Andfel Corporation is a supplier of twist ties, cable ties, security seals and tag attaching products. Polyethylene beaded ties are releasable, and come in a variety of colors. Nylon beaded cable ties are more rigid than the polyethylene ties, but offer more tensile strength. Our bolt seal closes easily with finger pressure but requires bolt cutters to remove. Plastic & wire snap locks are ideal for sealing meters, lever-lock drums, liquor kits, containers, instruments and zipper bags.
