PFAS: Phasing Out Banned Chemical Compounds
KNOWLEDGE IS POWER WITH REG’S PHASING-OUT BANNED PFAS Momentum is seemingly building to speed the phase-out of PFAS. Some states have now taken action regarding its use in direct food contact packaging. Let’s review what we’re dealing with: Per- and polyfluoroalkyl substances (PFAS) made their appearance in the 1940s, due to the attractiveness of properties […]

Aqueous Coatings Fundamentals: Temperature, Pressure, & Viscosity
The Essence of Aqueous Coatings The practice of applying a coating successfully is a result of understanding and being attentive to a few fundamentals. These are pressure, viscosity, and pile temperature. Success requires that these key variables be under control. Pressure in Aqueous Coatings PRESSURE: “KISS” is the key to a successful trouble-free coating application. […]
The Growth of In-Mold Labels: IML
In-Mold Labels: A Cost-effective, Sustainable Alternative Time flies, and as improbable as it may seem, in-mold labeling (IML) debuted in the late 1970s. Looking back historically, IML developed as a high volume, low cost, paper substrate driven market. The beginning applications consisted of long-run blow-molded branded bottles, and to a lesser degree, injection molded containers. […]
Gluing Aqueous Coatings
Two types of adhesives or glues are in common use to glue aqueous coated substrates. These are cold white glues and hot melt adhesives. The most widely used of these are hot melt adhesives which are a form of solvent-free thermoplastics. These are solid at room temperature and are melted to be applied as a […]
Blocking Or Sticking Of Aqueous Coated Surfaces
Blocking is a term given to describe sticking between two or more layers of coated substrate, which may be printed, or unprinted, and in roll, sheet, or package form.
Special Effects using Matte, Satin, and Gloss Aqueous Coatings
Aqueous Coatings create Special Effects Many different special effects may be obtained using aqueous coatings that are formulated to provide various levels of gloss. This range in gloss can extend from a very flat matte (reflecting only 15% of light) to very high gloss coatings that are able to reflect as high as 90% + […]
FDA Bans Chemicals in Food Packaging Coatings Update
Perfluoroalkyl Ethyl Toxicity Concerns in Food Packaging In January 2016, the U.S. Food & Drug Administration (FDA) published a final rule that prohibited the use of three specific perfluoroalkyl ethyl containing chemicals because of toxicity concerns. These chemicals had been in use to make paper and paperboard packaging resistant to oil and water for use […]
