New Non-Fluorinated Barrier Technology – AGC Chemicals

New Non-Fluorinated Barrier Technology - AGC Chemicals

Reading Time: 3 minutes

There has never been a non-fluorinated shaping additive that can protect paper products such as fast-food containers from both water and edible oils. This has changed with the development of AGC, a new weight-end additive that can be added to the fiber during production.

This next-generation physics solution will replace current technology that is being phased out due to regulatory concerns and consumer preferences. It is made from natural materials that are safe, while maintaining its effectiveness as a repellent to molded fibers.

FibraLAST additives prevent bleed-through of high-temperature liquids and edible oils through fibers – achieving 80°C water and oil holdout performance. They can be used as an alternative to traditional oil sizing products, which are spray-coated on the products after manufacturing.

In addition to being non-fluorinated, these additives are made from plant-derived components and do not contain silicon or heavy metals.

They are FDA compliant for all types of food contact with the following limitations:

  1. Maximum loading of 20% active ingredients by weight of oven-dried pulp
  2. add before create sheet
  3. Use in accordance with current good manufacturing practice

Kosher approval is pending, as is the manufacturing facility’s kosher certification. In addition, BFR and BPI-certified compostable certification is also pending.

Fluorinated vs. Fluorine-Free Barrier Technology

coat individual fiber Coats the fiber and fills the pores in the fiber network
The low surface energy of the fiber prevents penetration by high surface tension fluids A single wet-end additive repels both water and oil
Unique combination of chemical and physical barrier
Liquids face a difficult path to enter fiber networks


Application

Molded, formed fiber, and cardboard products, fast-casual bowls, plates, containers, and pizza boxes.

Exam Results

FibraLAST was tested for holdout performance with the TAPPI kit. 80 °C corn oil was poured onto an untreated fiber plate, left to sit for 2 h and observed. The same corn oil was poured onto the same type of fiber plate that was treated with FibraLAST. Virtually no bleed-through was observed on the treated plate and received a score of 4.

Then the same test was performed using 90 °C tap water, again showing virtually no bleed-through.

FibraLAST technology is designed for wet end process. Since the additives are applied to the paper pulp prior to fabrication, no additional equipment or process is required. Pulp and paper mills can cost-effectively scale their products with this barrier technology, providing a major competitive advantage for molded fiber products.

FibraLAST sizing agents are made in the USA and are patent pending.
