We have produced tapes for a wide range of industries and applications for over 30 years. We manufacture in Piedras Negras, Mexico, with key raw materials purchased in the United States. Products ship from our warehouse and headquarters in Houston, Texas. 

We make several grades of tape and inventory many common sizes used by the industries we serve. We are always eager to try something new, so custom size and custom product requests are welcome.
