Who & what is Sheldahl Flexible Technologies?

Knowing whom you are working with is important before working together. Let us introduce ourselves!

We are Sheldahl Flexible Technologies, a wholly-owned subsidiary of Flex. We manufacture materials and circuits used by the automotive, medical, industrial, and consumer industries marketed worldwide. Our technologies provide space and weight-saving solutions that combine our know-how and technical experience to enable greater technological possibilities.


We have been a company since 1955, beginning when G.T. Schjeldahl founded Sheldahl. Starting with the genius idea of using polyethylene plastic to create bread bags, Sheldahl grew to create special vacuum deposited materials that went into the first Echo satellites and unlocked the possibilities of our capabilities from there. What was once a simple bread bag-making business became an international business that was capable of serving the Automotive, Medical, Aerospace, Industrial, Consumer, Human Machine Interface, Heaters, and Smart Packaging markets. 


Today we create and provide Flexible Circuits, Printed Electronics, Electronic Materials, Industrial Materials, Optical Materials, and Vacuum Deposited Materials to those industries. Our diverse capabilities enable us to go beyond the ordinary to the extraordinary in solution thinking. You come to us with an idea, and we answer you with a solution that will serve you better than just getting the job done, and our history can back that.

Today, it's an idea, and tomorrow it's a solution. Let's work together

How long has Sheldahl been around, and what are some of the things you have done as a company?

Sheldahl Flexible Technologies, A Flex Company, has been around since our conception in 1955 by G.T. Schjeldahl when he found a way to simultaneously cut and seal together two sheets of plastic with a hot knife. Driven by his spirit of curiosity and creativity, Schjeldahl's innovation laid the foundation for immense growth and international fame with the Echo I 100-foot passive satellite launch on August 12, 1960, made with a thin polyester film vapor-deposited with aluminum and sealed with Schjeldahl's GT-301 tape. From there, Sheldahl created a line of flexible circuitry called Schjel-Flex, provided materials for the 1962 Buick & the Trimline Telephone, the Skylab repairs, and so much more.

G.T. Schjeldahl's curiosity and innovation set Sheldahl up for success 66 years later, allowing the company to be built on a firm foundation from the beginning. Sheldahl continues to push the envelope in flexible circuit capabilities through new environmentally friendly materials and their applications to today's technologies.

Today, Sheldahl Flexible Technologies manufacturers materials and circuits used by the automotive, medical, industrial, and consumer industries and is marketed worldwide. Sheldahl laminates are generally of two types: adhesive-based tapes and materials and the company's own patented adhesiveless material called Novaclad®. From these materials, Sheldahl makes single and double-sided flexible circuits.

You will find Sheldahl Flexible Technologies, with the strength of our parent company Flex Ltd, provides the most reliable business offering in the Flexible Printed Electronics, Vacuum Deposited Materials, and Electronic Materials space. Our vertical integration, automation, roll-to-roll flex circuit manufacturing, and assembly are unmatched in the industry.

Today, Sheldahl is where complexity and simplicity come together to create the extraordinary. Sheldahl evaluates your product design and the materials needed to make it a reality to provide the right technical solution for your application. Contact us today!

Why use a flexible printed circuit?

If the application is flat and 2 dimensional with no requirements for flexing, then use a PCB. If the application requires flexibility, or a 3-dimensional solution, or weight and size are issues, consider using FPC.

My design requires touch sensors. Can Sheldahl deliver a solution?

This is an application where FPC really comes into its element. We offer flexible and thin solutions. Moreover, Sheldahl has more material options available than anyone else currently building circuits, and we can specifically tailor the materials and design to give the optimum solution.

We have a long history of building product that ranges from simple PTF membrane switches to transparent, flexible etched ITO for capacitive switches. With multiple options in between depending on the end-user requirements.

I see from the website Sheldahl manufactures flex circuits how about assembly?

Our main focus is on designing and building the optimum solution for the bare FPC. Although SMD on FPC typically uses the same equipment that PCB uses, there are some additional nuances and requirements specific to processing flexible materials. We offer the options of providing the populated final product or offer assistance and guidance to our customers if they prefer to do the assembly themselves.
