How to Protect Your Products with Precision Foam Case Inserts

Whether you’re shipping or storing medical devices, electronic components, or valuable collectibles, the right foam case insert is the best way to protect your products. To get the 360-degree protection you want, the design and material selection for these inserts must be precise. What should you consider when choosing a foam material?

Thermal Insulation

For temperature sensitive products, foam case inserts will provide thermal insulation by acting as a barrier to sudden changes in temperature. Choosing the right foam with good thermal properties helps protect your items from damage caused by temperature fluctuations. Foams like expanded polypropylene (EPP) and polyethylene (EPE) are excellent for insulation because they trap air within their structure, reducing heat transfer. Consider that:

Products sensitive to heat or cold may require foam inserts designed specifically for thermal protection.
You may need to have additional insulating layers if your products are exposed to extreme environments.

Electrostatic Discharge (ESD) Protection

For electronics and other components susceptible to static electricity, specific types of foam inserts offer ESD protection against static discharges during handling and transport. ESD foams are treated with anti-static properties or conductive additives to dissipate electrical charges safely. Make sure to:

Choose ESD protective foams, such as carbon-infused polyurethane or cross-linked polyethylene (XLPE) with anti-static treatments, for items vulnerable to static electricity.
Ensure the foam complies with industry standards like ANSI/ESD S20.20 to ensure proper ESD protection.

Avoid Off-Gassing Foams

When transporting or storing sensitive products, it’s important to avoid foams that off-gas. Off-gassing occurs when volatile organic compounds (VOCs) are released from the foam over time, which can damage certain products, especially electronics, optics, or sensitive materials.

Ask manufacturers about the off-gassing potential of the foam and choose low-VOC options. Polyethylene foams, cross-linked polyethylene, or expanded polystyrene (EPS are often used because of their low off-gassing properties.

Non-Abrasive Foams

For high-end products with sensitive or polished surfaces (e.g., automotive parts, aerospace components, or luxury goods), avoiding abrasion is a high priority. These items, often described as having Class A surfaces, require foams that won’t scratch or mar the product during transport.

Soft foams, like ether-based polyurethane foams provide cushioning without causing damage to sensitive finishes. These foams are designed to be non-abrasive, ensuring that your products arrive in pristine condition. For ultra-sensitive items, consider using a foam lining coated with a softer material like velvet or felt.

Compression and Cushioning Properties

Foam with high compression resistance provides reliable protection for heavier or more fragile items, while softer foams offer gentle cushioning for lightweight or delicate products. Foams such as EPP or polyurethane are popular choices due to their excellent shock-absorbing properties. The foam’s compression deflection rate, which measures how much force is required to compress the material, is critical in determining its suitability for your application.

Remember that heavier items require foams with higher compression resistance. For more delicate items, use soft foams with low compression deflection to provide gentle support without excessive pressure.

Customizability

Every product is different, which means your foam inserts should be custom-designed to fit the exact dimensions and contours of your items. Foam fabrication techniques, such as die-cutting, water jet cutting, and CNC routing, allow for precise customization of foam inserts to match the shape and requirements of each product.

Durability and Longevity

For reusable cases or long-term storage, foam inserts need to withstand repeated use without degrading. High-density foams, such as polyethylene (PE) or neoprene, are well-suited for durable applications as they resist wear and tear over time.
