You can find insulated foam shipping boxes right here in our Office Supplies assortment, under shipping and packing. Options include molded foam coolers, corrugated mailers with foam inserts, and cartons paired with thermal liners—sold as singles or in multipacks.

• Browse by need: Look for insulated shippers, foam containers, or mailers with foil bag liners.
• Check specs: Review interior dimensions, wall design, and whether an outer carton is included.
• Order your way: Many items are available for delivery or store pickup, depending on location.

Availability and selection can vary, but starting on this styrofoam box page is a quick way to compare sizes and pack formats for your shipping or moving projects.

Yes—foam coolers are commonly used as an inner container for mailing, especially for items that benefit from insulation. The key is to pack thoughtfully and follow carrier guidelines.

1. Use a sturdy outer carton: Place the foam cooler inside a corrugated box to protect it in transit.
2. Pack out well: Add cold packs if needed and fill voids with cushioning to limit movement.
3. Seal and label: Close all seams with packing tape; add handling notes if appropriate.
4. Check rules: Review your carrier’s policies on perishables, ice packs, or other contents before shipping.

These steps can help improve temperature control and durability, but results vary based on contents, route, and weather. When in doubt, choose faster delivery options.

Start with your contents and how you plan to pack them. Interior space—not outside size—is what determines fit, so double-check dimensions and account for any cold packs or dividers.

• Measure your items: Add room for gel packs and cushioning on all sides.
• Match insulation to transit time: Thicker walls or double-insulated sets can help for longer routes.
• Consider weight handling: Ensure the outer carton and foam insert are rated for your load.
• Choose pack format: Singles are great for one-offs; multipacks help if you ship frequently.

If you’re between sizes, sizing up slightly can create space for proper cushioning and tape seams, which can help protect contents during shipping.

People often use that word to describe polystyrene foam in general, but there are different types. Most insulated shipping coolers here are made from expanded polystyrene (EPS), which is molded into thick-walled boxes.

• EPS foam: Common for shipping coolers; lightweight, with bead-like texture.
• XPS foam: Another polystyrene form, typically denser sheets used in other applications.
• Check the details: Product pages usually note the insulation style and whether there’s a matching outer carton or liner.

Both are polystyrene-based materials, but their structure and performance characteristics differ. Reviewing product specifications can help you choose the insulation style that fits your shipping needs.

You can often reuse foam coolers for non-critical tasks if they’re clean and intact. Before reusing for shipping, give the container a quick check and consider your contents.

• Inspect first: Look for cracks, crushed corners, or gaps that could reduce insulation.
• Clean and dry: Wipe with mild soap and water, then air-dry completely to avoid moisture.
• Know your use: For temperature-sensitive items, many shippers prefer new or like-new packaging for consistent performance.
• Dispose responsibly: If it’s past its prime, check local options for drop-off recycling or repurpose for storage and organization.

Condition, route, and packing method all affect performance, so reuse when it makes sense and replace when protection or hygiene might be compromised.
