At the beginning of Holscot’s history, it was the Teflon® Roll Cover which inspired our company to be establish, since then, Teflon® or rather fluoropolymers have been the bedrock of our business, providing benefits to a multitude of industries across a breadth of applications.
In our early years, when FEP sleeves were in their infancy and were exclusively supplied by DuPont de Nemours, it was the printing industry, the textile industry and the paper industry which were the biggest users of these innovative products. In the printing industry, aggressive inks were causing contamination problems, in the textile industry the dyes would impregnate the roller surfaces and cause mark off on the fabric. In the paper industry the build-up of sticky substances were giving rise to a deterioration in product quality, all these problems were detrimental to operational efficiency. The unsurpassed Non-Stick capability of the Teflon® FEP Heat Shrinkable Roll Covers meant the virtual elimination of these problems.
As the reprographic industry expanded rapidly more companies started to use in house photocopiers and printers. These items employed the use of Teflon® surfaces on rollers used in the hottest part of the machine (in particular the rubber pressure roller), this necessitated the use of PFA as the sleeving material due to its greater temperature resistance.
The use of PFA in such an arduous environment ultimately led to its use in the Liquid Packaging Industry. As people increasingly turned to cartons for containing liquids such as fruit juices, wine and milk, the manufacturers of this Aseptic Packaging expanded into markets across the world. See our case study where we proudly manufacture PFA roller supplied to TetraPak.
Within the manufacturing process of Aseptic Packaging, an extruded curtain of PU is nipped between the card and the foil liner and it is at this location where a Teflon® surface is needed. Because of the intense heat and pressure, PFA is the material of choice.
As the industries which primarily used Teflon® Roll Covers relocated around the world we have followed the market by establishing distributorships in many different countries including the US, China, Thailand, Taiwan and Indonesia.
Holscot is different to nearly all our competitors in that we manufacture all the FEP and PFA sleeves we supply, the majority of our competitors do not. We have 8 in-house extrusion lines and our own etching capability for both sodium napththalene and sodium ammonia, again an increasingly rare facility.

New markets have opened up for FEP and PFA heat shrinkable sleeves, including battery packs, chemically resistant flexible joints, cord encapsulation and, perhaps most notably, the covering of lamps to provide shatter resistance.
