Brief History

Sealstrip’s roots began with Formatron, founded in 1959, by Pat Forman. Intrigued by the new shrinkable film introduced by DuPont, he built and patented the first Automatic L-Sealer for shrink packaging.

In the late 1960’s, in response to customer requests for an easy open system for shrink packaging, Pat Forman invented Shrink-String. Shrink-String was applied on the inside of the shrink film, by a Shrink-String applicator and provided an easy open for shrink packaging.

In 1967, Tearstrip Systems, Inc. was formed to manufacture the newly developed Shrinktape and the required applicator to be retrofitted to various shrink-wrappers.

In the late 1970s, in response to a customer request, the Sealstrip® Resealable Package was developed. Sealstrip provides easy open, reseal and tamper evident features.

In 1979, Sealstrip Corporation was formed to manufacture the newly developed Sealstrip System tape and the required applicators that were retrofitted to various wrappers.

The two companies, Tearstrip Systems and Sealstrip, worked together, answering consumer demands for easier packaging. The systems include pressure sensitive tapes and the applicator/converting equipment to create the convenience features for flexible packaging.

In 2002, the two companies merged and have since been providing easy open and resealable features as Sealstrip Corporation.

Over the years, Sealstrip has counted some of America’s largest and best known companies as our loyal customers. The company growth has been measured and deliberate, and we have experienced the ups and downs of the consumer economy over several decades.
