tesa® 4818 — tesa® PTFE tapes + EKO‑TECH expertise

Q: Do you ship across the EU?

Yes—Poland and wider CEE/EU with commercial documents and standard logistics partners.

Q: Is tesa 4818 food‑contact approved?

Application‑ and region‑specific. Tell us your regulatory needs and we’ll check the latest documentation.

Q: Can you provide die‑cut PTFE pads for jaw faces?

Yes— die & kiss‑cut parts on release liner, labeled for quick changeovers.

Q: Can you supply narrow rolls for sealing bars?

Yes— slitting to any width within the material’s capability is our standard service.

Q: How hot can it run?

The tape is used in processes up to 260 °C . Always validate in your specific setup.

Q: What makes tesa 4818 different from standard PTFE films?

tesa 4818 uses a glass‑cloth backing saturated/coated with PTFE for higher tear resistance and dimensional stability vs. pure PTFE film tapes.

tesa® 4818 is a PTFE‑saturated glass‑cloth tape with a silicone adhesive—a go‑to non‑stick, low‑friction surface for heat‑seal bars and jaws. As a tesa Platinum Converter based in Poland, EKO‑TECH Sp. z o.o. Sp.k. designs and converts tesa® PTFE tapes for demanding industrial processes across Poland and Eastern Europe.

With local consultation, application trials, and fast converting, we help you specify the right tesa PTFE tapes and deliver them ready to install—from narrow slit rolls to complex die‑cut formats.

Applications for tesa® 4818 PTFE tapes

Use tesa 4818 where a robust, clean‑release PTFE surface improves uptime and seal quality:

Heat‑sealing equipment
Anti‑stick lining on seal bars, jaws, and plates in packaging lines to prevent film build‑up and sticking during continuous or impulse sealing.
High‑temperature masking (>200 °C)
Durable masking of contact surfaces that require a non‑stick layer during thermal processes.
Low‑friction guides & chutes
Gliding surfaces for webs, bags, and parts to reduce drag and prevent jams in material transport.

Ask us for a data‑driven fit: thickness, release behaviour, and wear life vs. your film and sealing parameters.

Why partner with a converter — and why EKO‑TECH

Benefits of an experienced converter

Right tape, right place: we translate process parameters into a matched PTFE tape solution.
Less downtime: converted parts ship ready‑to‑install, making changeovers faster and more repeatable.
Cost control: we optimize roll widths and part nesting to reduce waste.

Why EKO‑TECH (tesa Platinum Converter)

Deep tesa® know‑how: direct access to tesa application support and best practices.
Local service in Poland & CEE: fast communication, technical visits, and flexible MOQs.
Quality & traceability: consistent converting, documented batches, and stable supply.

Converting options for tesa® 4818 (made‑to‑measure)

We design, modify, and define the format that fits your machine:

Slitting: narrow to wide rolls, clean edges, core IDs to your spec
Die & kiss cuts: gaskets, windowed strips, finger‑lifts, tabs; supplied on liner for quick application
Format sets: matched left/right jaws, pad sets, and changeover kits
Lamination: optional liners, pull‑tabs, or additional functional layers if required
Kitting & packaging: labeled, sequenced, and ready for the line

Send a drawing—or a worn sample—and we’ll reverse‑engineer the geometry, then pre‑test on equivalent substrates.

Made in Poland

While the base material is manufactured by tesa, the converted product is made in Poland by EKO‑TECH. We add value by tailoring width, shape, liner, and presentation so the tape fits your equipment, cycle time, and quality targets. Local converting also means shorter logistics chains and responsive iterations.
