Igloo Coolbox 10 qt Cooler
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes rotomolded polyethylene, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What Igloo Coolbox 10 qt Cooler is made of, ingredients and materials
The Igloo Coolbox 10 qt is constructed from rotomolded polyethylene (HDPE or similar), a durable plastic formed by heating and rotating liquid resin in a mold until it solidifies into a thick, seamless shell. This process creates a material with no applied coatings, glazes, or chemical finishes that could degrade or leach over time. Polyethylene in food-contact applications is chemically stable and does not contain BPA, phthalates, or other endocrine disruptors in its base formulation. The material's thickness and manufacturing method make it resistant to cracking, which reduces microplastic risk compared to thin-walled plastics.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Microplastics
Rotomolded polyethylene is durable, but UV exposure, repeated temperature cycling, and physical stress over many years can cause small cracks and fragment shedding. Risk is lower than thin-walled plastics but cannot be eliminated entirely with age.
Source, EPA ↗Bacterial or mold growth in seams and interior surfaces
Coolers retain moisture and food residue, especially at seams and under the lid seal. Rotomolded construction minimizes cracks where bacteria hide, but regular thorough cleaning is essential to prevent pathogenic growth.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Rotomolded polyethylene food-contact grade does not contain BPA or phthalates in its formulation. No additives are typically disclosed, but the resin itself is not a source of these chemicals.
Source, FDA ↗Leaching from adhesives or fasteners
Rotomolded coolers are formed as one piece with minimal glued joints; metal hinges and latches on the lid may corrode or release trace metals if exposed to acidic foods, but this is not a documented issue for Igloo models in normal use.
Off-gassing or VOC emissions
Polyethylene has minimal volatile organic compound off-gassing compared to foam or upholstered containers. No reported odor or chemical irritation issues are documented for this product line.
The full breakdown
The brand's record and disclosure
Igloo has not published a public PFAS statement or sustainability certification for this model, and the brand does not advertise specific material testing or third-party verification. No recalls specific to leaching, coating failure, or chemical safety have been documented for this cooler line. The company operates in a category (hard-shell coolers) where voluntary disclosure is uncommon; absence of a statement does not indicate a problem, but reflects industry norms around transparency.
How it compares in its category
Rotomolded polyethylene coolers like this one present lower concern in the lunch box and cooler category because they avoid epoxy-lined metal interiors (which can contain BPA or degradable coatings) and soft-sided fabric containers with adhesives or waterproof treatments. This design is more durable than cheaper foam-core models that fragment over time. Compared to insulated stainless steel or ceramic lunch containers, polyethylene coolers are cheaper but less premium; compared to low-cost plastic coolers, rotomolded construction is thicker and more resistant to degradation.
If you buy it
Keep the cooler out of direct sunlight for extended periods, as UV exposure can cause polyethylene to become brittle and crack over decades; store indoors when not in use. Do not fill with hot liquids above 140°F (60°C), as sustained heat stress may cause subtle warping or accelerate any minor mold growth in seams. Clean thoroughly after each use, especially interior seams where moisture and food residue accumulate, to prevent bacterial or fungal growth. Replace if the interior develops persistent cracks, deep gouges, or a musty odor that cleaning does not eliminate.
