What zarges K470 Aluminum Storage Case 40845 is made of, ingredients and materials
The K470 is constructed primarily from aluminum alloy (exact composition not publicly detailed by Zarges, but typical for industrial cases). Aluminum itself does not leach problematic chemicals under normal storage conditions, unlike some plastics or ceramics with problematic glazes. The rubber gasket and hinges are the secondary concern; Zarges does not publicly disclose elastomer composition, so phthalate content cannot be ruled out, though industrial-grade rubber in sealed storage rarely contacts food or skin directly.
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.
Aluminum corrosion and leaching
Under normal dry storage, bare aluminum poses minimal leaching risk. However, if stored in highly acidic, alkaline, or salt-heavy environments (coastal areas, chemical storage), aluminum can corrode and release trace aluminum ions; this is not a concern for typical consumer storage but relevant if contents are corrosive.
Bacterial or mold growth in seal
Rubber gaskets can harbor bacteria or mold if the case is opened/closed frequently in humid environments and not cleaned regularly. This is a maintenance issue, not a chemical hazard, but relevant for hygiene if the case stores consumables or medical supplies.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Zarges does not publicly disclose gasket elastomer composition. Industrial-grade rubber in sealed storage applications rarely contacts skin or food, minimizing exposure. No recalls or complaints on record for this product.
Source, FDA ↗VOC or off-gassing from coatings
The K470 uses bare aluminum and rubber; no paint, foam, or plastic liners are mentioned in product specs. No off-gassing risk is known for this configuration.
Heavy metals
Hinges and hardware are not detailed in public materials; industrial aluminum cases typically use aluminum or stainless steel fasteners, not cadmium or lead-plated hardware. No known recalls for heavy metal content.

The brand's record and disclosure
Zarges is a German manufacturer specializing in reusable transport and storage cases, with a long-standing reputation for industrial durability and ISO certifications (ISO 9001). The company does not publicly market safety certifications for chemical content (BPA-free claims, etc.), which is typical for non-food-contact industrial equipment. No major product recalls or chemical controversies on record for this model. Zarges maintains transparency on materials for professional/industrial customers but does not target consumer safety-conscious marketing.
How it compares in its category
Aluminum storage cases like the K470 present lower concern than plastic storage bins or composite cases for long-term storage, as aluminum is not a material linked to off-gassing or leaching organics. Compared to steel cases, aluminum offers corrosion resistance without coatings that could degrade. The main trade-off is that aluminum is softer and requires care to avoid dents; the rubber gasket design is industry-standard for weatherproofing and poses lower hazard than foam or adhesive-sealed alternatives.
If you buy it
Store the case in cool, dry conditions; avoid prolonged contact with strong acids or alkalis, which can corrode aluminum. The rubber gasket should be cleaned periodically to prevent mold or bacterial growth if the case is opened/closed frequently in humid environments. Do not use for long-term food storage or potable water storage without an internal liner, as the aluminum surface and rubber composition are not food-contact certified. Replace the gasket if it becomes hardened, cracked, or no longer seals effectively, as seal failure reduces weather protection.
