Expandable foam packaging bags are designed to help cushion and stabilize items inside a box during moving or shipping. When activated per the package directions, they expand to fill voids and conform around your item, creating a snug, protective cradle.

• Helps reduce shifting and impacts in transit.
• Useful for irregular shapes that don’t fit standard inserts.
• Offered in multiple bag dimensions (e.g., 15"x18", 18"x24", 22"x27").
• Available in standard, heavy-duty, and extra-thick options for added cushioning.

These features can be a strong complement to your moving boxes and other packing materials. Results can vary based on item weight, box size, and packing technique, so always follow the instructions on the packaging.

You can shop expandable foam packaging on Walmart.com in the Office Supplies category, often under Packing Materials or Moving Supplies. Product pages list dimensions, case quantities, and other details so you can compare options.

• Search terms to try: “expandable foam bags” or “instant foam packaging.”
• Use filters to browse by size (e.g., 15"x18", 18"x24", 22"x27") and pack type.
• Look for notes like “for 8"x8"x8" box” or “for 18"x12"x12" box.”

Availability and pickup or delivery options can vary by location and time. Checking Walmart.com for current stock is a good way to see what’s ready to order today.

A quick way is to match your box and item to the listed bag dimensions and any suggested box guidance on the product page.

1. Measure your box (e.g., 8"x8"x8" or 18"x12"x12").
2. Check bag dimensions (e.g., 15"x18", 18"x24", 22"x27").
3. Look for listings that note a compatible box size.
4. Choose heavy-duty or extra-thick versions if you want added cushioning for heavier or more delicate items.
5. Consider a sample or variety pack to test multiple sizes before buying a full case.

These steps can help you narrow in on a fit, but the best choice may vary with your item’s shape, fragility, and how you pack the box.

There are several case and bulk options on Walmart.com, so you can order just enough for a small project or stock up for frequent shipping.

• Common case counts include 24, 30, 36, 72, 96, and 180 bags (varies by size).
• Bulk packs are available for popular dimensions like 15"x18" and 22"x27".
• Some listings are sold by the carton, while others are larger bulk cases.

Exact quantities depend on the specific product listing. Review the product title and details for the bag dimensions, case count, and notes on compatibility with certain box sizes. Availability can change, so check the page for the latest options.

If you’re unsure which bag will fit your items best, look for multi-size assortments on Walmart.com. These can help you trial different options without committing to a large case.

• Small sample packs often include multiple sizes (e.g., #10, #20, #40).
• Large sample packs may focus on bigger sizes (e.g., #60, #80, #100).
• Some variety packs include a range (e.g., #10 through #100), sometimes with two of each listed size.

Contents vary by assortment, so check each product page for the exact sizes and quantities included. Once you find a good fit, you can switch to a case or bulk pack of that specific size.
