UV Anti-Slip Varnish

Product Introduction

---

StarColor UV Anti-Slip Varnish is a functional UV-curable coating designed to add controlled friction to printed surfaces. It helps prevent slippage and shifting of packaging during stacking, transport, and storage. With a low-gloss, textured finish, this varnish improves handling safety without affecting print readability or design aesthetics. It cures instantly under UV or LED systems, making it ideal for high-speed production lines in the packaging and logistics industries. Perfect for folding cartons, trays, sleeves, and industrial labels, this varnish offers excellent adhesion, anti-blocking properties, and compatibility with a wide range of substrates and printing methods.

FAQ – Frequently Asked Questions

Q1: What is UV anti-slip varnish used for?

A : UV anti-slip varnish is applied to printed packaging surfaces to increase friction and prevent slippage. It is especially useful for folding cartons, trays, and logistics packaging that need to stay stable during stacking, transportation, or display.

---

Q2: How does this varnish help in packaging logistics?

A : By increasing the surface’s coefficient of friction (COF), the varnish reduces the risk of printed cartons or trays sliding, shifting, or collapsing when stacked—making packaging safer and more secure during handling and shipment.

---

Q3: Can it be used on food packaging?

A : Yes. The varnish is formulated without VOCs, heavy metals, or formaldehyde. It meets ROHS and REACH standards, making it safe for use on the non-food-contact side of food packaging.

---

Q4: What printing methods is it compatible with?

A : StarColor UV Anti-Slip Varnish is compatible with multiple printing methods including flexographic, offset, and screen printing. It integrates easily into existing production lines and cures instantly under UV or LED light.

---

Q5: What substrates can this varnish be applied to?

A : It works well on paperboard, corrugated board, and select plastic films such as BOPP and PET—making it suitable for a wide range of packaging materials.
