Sustainability has become a buzzword-often without real world meaning.

Metal closures are part of the true circular economy. Steel is the most recycled material in the world, and both steel and aluminum can be infinitely recycled with no quality loss. A metal cap can become a car door . . . and a car door can become a metal cap! Metal caps have a minimal environmental footprint, and Keystone Cap partners with suppliers who share our commitment to sustainability.

​

Whenever you buy metal caps from us, you're choosing a product that's already part of the recycling loop - today, tomorrow, and forever.
