What Large 2-Layer KOR Kit is made of, ingredients and materials

The KOR Kit combines an aluminum or steel exterior shell with polymer-based interior fittings and foam inserts. Aluminum cases do not leach harmful metals under normal storage conditions; any polymers used for latches, seals, or padding are secondary components not in direct food contact. The closed, rigid design minimizes off-gassing compared to soft-sided storage, and metal/rigid plastic materials do not degrade into microplastics during typical use.

💨

Polymer off-gassing from interior fittings

Interior foam inserts, latches, or gaskets may be made from polyurethane, polystyrene, or other polymers. Off-gassing of volatile organic compounds (VOCs) is minimal in well-ventilated storage but may increase if case is sealed and stored in warm conditions for extended periods.

🫧

Foam degradation and particulate shedding

Foam padding can degrade, compress, or shed particles over 5-10 years of use, especially if exposed to heat or UV light. This is primarily a contamination concern for sensitive stored items rather than a direct health hazard to users.

70/ 100
⚠️

Microbial growth in seals and interior

If the case is stored in humid conditions or used to transport moist items without drying, gaskets and interior surfaces may develop mold or bacterial colonies. Regular inspection and drying prevent this; not a manufacturing defect but a user-maintenance issue.

What’s reassuring

✅

Base material not linked to PFAS

The main material recorded for this product is not one associated with PFAS.

100/ 100
✅

Aluminum leaching

Aluminum cases do not leach aluminum into stored contents under normal conditions. Risk only exists if storing acidic or alkaline solutions directly in contact with uncoated aluminum; dry goods and sealed items face no hazard.

95/ 100
✅

Metal coating integrity

Cases are powder-coated or anodized aluminum; no lead or cadmium in coatings is indicated in available information. Coating should not flake or corrode under normal storage conditions.

How is this PFAS grade calculated?

The brand's record and disclosure

The brand is a German manufacturer specializing in transport and storage cases; the company does not publicly disclose detailed material certifications or chemical composition breakdowns on consumer-facing channels. No product safety recalls, chemical hazard allegations, or regulatory actions against KOR products are on record. The brand maintains silent positioning on PFAS and other non-legacy chemicals, which is typical for industrial equipment manufacturers rather than consumer goods companies.

How it compares in its category

Hard-shell storage cases like the KOR Kit are inherently lower-risk than soft fabric cases or thermoformed plastic boxes, which can off-gas volatile organic compounds or degrade polymers over time. Metal and rigid polymer cases are chemically inert during storage of non-corrosive items and do not require frequent replacement. Cases are premium-priced but built for longevity, reducing replacement waste and cumulative chemical exposure versus disposable alternatives.

If you buy it

Store the case in moderate temperature (avoid prolonged exposure above 50°C/122°F), as sustained heat may degrade polymer seals or foam inserts. Inspect foam padding and gaskets annually for degradation or compression; replace if crumbling or no longer sealing effectively. Keep interior dry to prevent mold or corrosion of metal components. Do not use for storing strong solvents or corrosive chemicals, as they may degrade internal polymers or cause metal oxidation.
