Description
These #80 Quick RT foam packaging bags provide an efficient, on-demand solution for protecting products during shipping without the need for equipment or machinery. Designed to fit 18x12x12 boxes, these protective foam cushions expand on activation to form custom foam cushions that block, brace, and protect items in transit.
Instapak Quick RT technology allows users to create foam-in-place packaging anywhere it’s needed. Each bag expands up to 27 times its original size, creating a protective foam mold around the product while using minimal storage space prior to activation. This makes Quick RT foam bags ideal for operations with limited warehouse space or variable packaging needs.
The Instapak Quick Tuff foam used in these bags delivers reliable shock absorption and durability, making it well suited for shipping fragile, heavy, or irregularly shaped items. Once expanded, the foam conforms to the product’s shape, helping prevent movement, vibration, and impact damage during handling and transportation.
These foam packaging bags are commonly used in manufacturing, e-commerce fulfillment, electronics shipping, and industrial packaging environments where product protection and efficiency are critical. Because no special tools or equipment are required, Quick RT foam bags are also ideal for remote packing stations, low-volume operations, or temporary packaging setups.
Using foam bags for shipping can help reduce damage claims, improve customer satisfaction, and streamline packing workflows. The bags activate easily by following the included instructions, and optimal performance is achieved when stored and used within the recommended temperature range of 65°F to 90°F (18°C to 32°C).
Designed specifically for 18x12x12 cartons, #80 Quick RT foam packaging bags provide consistent cushioning performance while allowing packers to create custom-fit protection for each shipment. Whether used for electronics, medical devices, automotive components, or other sensitive products, these protective foam cushions offer a practical, space-efficient alternative to pre-formed foam or loose fill materials.
These foam packaging bags are commonly used inside insulated shipping coolers or corrugated boxes to provide added blocking and bracing for fragile shipments.
