Our end-of-line case sealers and case erectors set the industry standard over 50 years ago, and our high quality engineered machines are still setting the standard today. Inventing of the Packaging Machine The first case sealing packaging machine was invented by Winton Loveland and Saul Warshaw. In 1962 they founded a company to manufacture and sell their invention. Their ‘Case Sealing’ machine applied gummed paper tape to corrugated boxes. The gummed tape machine sealed boxes – regular slotted cartons – and kept them closed. This invention significantly reduced shrinkage (theft) in transit, and radically improved the efficiency of end-of-line packing operations. They called the machine a Padlocker, and they called their company Loveshaw.
