Why Toyo Ink’s LIOELM TSL-LV makes flexible films run smoother

With LIOELM TSL-LV, Toyo Ink wants to tame the stubborn friction of modern polyolefin films so that packaging webs glide instead of juddering through high-speed lines. In practice that means fewer squeaks, less heat, and a calmer, more predictable converting floor.

What LIOELM TSL-LV is made for

LIOELM TSL-LV is a low-volatility slip additive designed for polyolefin resins, especially polyethylene and polypropylene films used in packaging and industrial roll stock, according to Toyo Ink’s materials information for the LIOELM series. Toyo Ink product overview

The additive is blended into the resin rather than coated on top, so film makers see the slip effect develop as the film cools and stabilises. That makes it attractive for high-throughput blown or cast film lines that cannot slow down for extra surface treatment.

How it changes film behaviour

In day-to-day use the promise is simple: reduce the coefficient of friction between film layers so rolls unwind more smoothly and bags separate with less force. That sounds dry, but operators notice it immediately when stacks stop sticking and feeding issues calm down.

Strengths in demanding lines

Where the additive plays out its strengths is in multi-layer films for food and industrial packaging, where both low friction and clean surfaces matter. Lines that run at several hundred meters per minute gain stability when slip performance remains consistent over the roll.

Because LIOELM TSL-LV is tailored for low volatility, converters aiming at high-clarity films or sensitive laminations can push productivity without constantly cleaning deposits from corona treaters, nips, and doctor blades. That directly cuts unplanned downtime on busy shifts.

Limits and trade-offs

No slip additive is a magic wand, and LIOELM TSL-LV is no exception. Process engineers still need to tune loading levels carefully, since too much slip can make winding loose or complicate registration in downstream printing.

Compared to more basic slip masterbatches, the material cost will often be higher, so its sweet spot lies in demanding, value-added films rather than commodity bags. For very thick technical sheets, other additives or mechanical solutions may remain more economical.

Where Toyo Ink positions the series

Toyo Ink has steadily broadened its polymer additive portfolio beyond classic printing inks, positioning the LIOELM line as part of a wider functional materials business that targets electronics, packaging, and industrial components. Toyo Ink annual report

The emphasis on low-migration, low-volatility chemistries fits regulators’ increasing focus on materials that touch food and consumer goods. For buyers of packaging films, that regulatory comfort can weigh just as heavily as a good friction curve.

Context for investors

For Toyo Ink SC Holdings, specialty products like LIOELM TSL-LV form one of several pillars alongside printing inks and colorants, helping the group diversify into higher-margin materials. They are rarely headline grabbers, but they tie Toyo Ink into long-lived customer relationships.
