Keystone Tape & Supply Co. was founded in 1996 and located in Placentia, Ca. The owners, Rory and Chad McWilliams, incorporated in 1999 and relocated to Anaheim, Ca. During the early days the company was primarily a wholesale operation of pressure sensitive tapes and films. Throughout the following years the Keystone acquired precision slitting and die cutting equipment in order to develop an additional presence in the industry. Chad’s 35 years experience in the tape industry, 8 in manufacturing and 27 in distribution , make Keystone an excellent resource, representing over 30 domestic and international manufactures of pressure sensitive tapes, adhesives, and films. Our team of experienced and dedicated sales people are ready, willing, and more than able to assist you with any problems or needs that may arise.
