Once activated, the foam creates a heavy-duty, shock-absorbent \"cradle\" that eliminates movement and protects your most valuable contents during transit.\u003c\/li\u003e\n\u003cli\u003eRapid Instant-Activation Technology: Experience a \"custom fit\" in seconds. By simply pressing the \"L\" mark and mixing the internal components, the bag expands instantly to fill gaps and surround your items. No loose peanuts or messy bubble wrap required—just clean, high-performance cushioning that stores flat and saves 90% of storage space until needed.\u003c\/li\u003e\n\u003cli\u003eOptimized PC \u0026amp; Electronics Shipping: The ultimate solution for high-end PC builders. For internal hardware protection, place the bag inside the chassis at the very start of expansion. It will naturally mold around the graphics card and CPU cooler, providing a secure fit that prevents component damage without the risk of over-expansion against sensitive parts.\u003c\/li\u003e\n\u003cli\u003eSimple \"Press \u0026amp; Pat\" Operation: Easy enough for anyone to use—just press the \"L\" zone until it pops, pat\/rub the mixing area approximately 25 times, and guide the expanding liquid to the corners. For optimal compression and support, we recommend using our 21\" x 30\" shipping foam (optimized for 16\" x 16\" x 16\" boxes) or our 18\" x 30\" shipping foam (optimized for 12\" x 12\" x 12\" boxes).\u003c\/li\u003e\n\u003cli\u003eSafety \u0026amp; Performance Tips: Please note that the chemical reaction generates temporary heat during activation; wearing gloves is recommended. For first-time users, watching the instructional video on the product page is highly recommended to master the timing and ensure your items are perfectly nested before the foam fully sets.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e GECBEKK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polyurethane\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 24\"L x 18\"W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Blue\/White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 Ounce\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Brand: GECBEKK","offers":[{"title":"Default Title","offer_id":44069661081690,"sku":"B0H15KBK4F-size-big","price":49.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0751\/1438\/1402\/files\/415duqy8ClL.jpg?v=1789339020","url":"https:\/\/shopstead.us\/products\/expanding-foam-packaging-4-pack-shock-absorbing-self-expanding-foam-packaging-bags-for-secure-shipping-of-computers-precision-goods-2x-18x30-2x-21x34-size-big","provider":"Shopstead","version":"1.0","type":"link"}
