Technology

Cellulose-based materials are already coveted for their high thermal stability, effective oxygen barrier function, chemical and mechanical resilience, ability to fully biodegrade and non-toxic nature.

These characteristics make cellulose and its derivatives the material of choice for environmentally friendly packaging, food service applications and single-use disposable goods. However, a key challenge of the format for these sectors is its hydrophilicity and many of the available coating solutions which can be used to add water-resistant properties to cellulose based materials, including fossil-fuel based resins and polymers, are harmful to the environment.

PROTĒAN® is an environmentally friendly additive and barrier coating platform technology that improves cellulose-based materials used in packaging solutions for packaging, pulp and paper manufacturers.


When utilizing a PROTĒAN® based formulation, the final product can potentially maintain the biodegradable properties of cellulose, but still provide superior water, oil and grease resistance.


PROTĒAN® can also be used as an emulsifier by being added to binders to make paper-based products oil and grease resistant. Due to the composition, PROTĒAN® resists blocking, solving a long-running issue for some barrier coating alternatives.


The formulations contain no volatile compounds, can be converted into high solids coatings and offer an easy, drop-in solution that can be used by all commercial mills without a large capital investment. This adaptable chemistry also has great potential for new formulations and technologies to be developed.

PROTĒAN® Water Barrier

Sustainable Water-resistant Solutions for Paper-based Packaging

PROTĒAN® Water offers eco-friendly coating solutions for single-use paper packaging products which must be durable, versatile, visually appealing and provide superior water-resistance. It replaces traditional plastic coatings, bioplastics, waxes and silicones.

The plant-based formula is a recyclable, efficient and cost-effective alternative for pulp & paper manufacturers.

PROTĒAN® Water Barrier Benefits


PROTĒAN® Water is distinguishable from competitive legacy technologies in four key areas:

Sustainability

  • Derived from natural and renewable resources
  • Coated paper is re-pulpable
  • Exemplary formulations are BPI-certified

Efficiency

  • Compatible with existing paper mill coating and converting operations
  • Excellent mill runnability, product convertibility and printability
  • Coats and dries quickly

Versatility

  • Suitable for hot and cold products
  • Can be applied on one or both sides of paper
  • Suitable as an emulsion for other coating agents
  • Compatible with bleached or unbleached papers

Safety

  • FDA approved under 21 CFR 172.867
  • Meets specifications described in Generally Recognized as Safe (GRAS) notices GRN 227 and 325
  • BfR XXXVI compliant
  • Non-toxic

PROTĒAN® OGR Barrier

Sustainable Oil and Grease-Resistant Solutions for Paper-based Packaging

PROTĒAN® OGR offers the ability to formulate eco-friendly coating solutions for paper packaging products in the food service and retail sectors. This technology is FDA-approved for food contact, offers superior oil and grease resistance properties. This allows manufacturers to replace papers which are treated with harmful fluorochemicals or use plastic coatings.

As a truly green alternative our formulations offer double the range of 3M kit values when compared to existing fluorine-free alternatives. The grease barrier properties allow the paper-based packaging to maintain dry strength while delivering impressive grease-resistance properties to paper with a lower overall coat weight.
