Titanium Dioxide R216 is food‑contact‑compliant rutile titanium dioxide specially developed for food‑safe paper packaging. Produced with strict raw material screening and alumina‑silica composite surface treatment, it meets food‑contact material requirements with controlled heavy‑metal impurities. It delivers high whiteness and excellent opacity, disperses uniformly in pulp system with good retention performance. It improves brightness, covering property and surface quality of food‑contact paper

Product Detail

Product Overview

Titanium Dioxide R216 CAS 13463‑67‑7 is sulfate‑process rutile titanium dioxide tailored for food‑contact paper packaging. Rigorous impurity control ensures compliance with food‑contact application requirements. Optimized composite surface treatment enhances wettability and retention inside aqueous pulp medium. This grade solves industry pain points including non‑compliant heavy‑metal index, insufficient whiteness and low pigment retention for food‑grade paper. Reliable quality supports large‑scale wet‑end dosing production of food‑safe packaging paper.

Key Features

Food‑contact compliant grade, strict heavy‑metal control, suitable for food‑contact paper packaging scenarios.
High whiteness and opacity, upgrade visual appearance and covering performance of food‑grade paper.
Good dispersion and retention in pulp, reduce pigment loss and avoid surface speckle defects.
Improve paper surface smoothness and post‑processing adaptability for printing and coating.
Good compatibility with plant fiber and food‑safe papermaking auxiliaries.
Stable chemical inertness, no adverse migration risk under normal paper packaging usage conditions.

Main Applications

‑ Food‑contact packaging base paper

‑ Food wrapping paper and bakery paper

‑ Food‑grade paperboard for food container

‑ Food‑contact label base paper

‑ Other paper packaging materials requiring food‑contact safety standard

Usage Recommendation

‑ Recommended dosage: 2‑9 wt% based on dry pulp weight, adjust according to whiteness and opacity requirements.

‑ Prepare well‑dispersed TiO₂ slurry before adding to pulp chest.

‑ Cooperate with food‑contact‑approved retention aids to improve pigment retention.

‑ Strictly avoid cross‑contamination with non‑food‑grade raw materials during whole production process.

‑ Perform small‑scale papermaking trial and safety‑relevant index verification before mass production.

Storage & Packaging

‑ Packaging: 25kg moisture‑proof kraft paper bag with PE inner liner.

‑ Storage: Store in dry, cool and ventilated warehouse, keep tightly sealed against moisture absorption; separate storage from non‑food‑grade industrial raw materials.

‑ Shelf life: 24 months under standard storage conditions.
