Instapak foam cushions, produced by Sealed Air, protect fragile shipments but pose recycling challenges due to their composite materials. The company offers a dedicated return program to handle these cushions, diverting them from landfills. Reuse remains the preferred initial step for extending their life.
Instapak foam cushions consist of polyurethane foam encased in a polyethylene film, often in silver, blue, white, or pink colors. The foam forms on-demand by mixing two liquid chemicals that expand up to 280 times their volume, creating custom-fit protection for items like electronics and medical devices. This construction makes Instapak incompatible with curbside recycling and most foam recycling programs, including those for expanded polystyrene.
The optimal approach is reuse. These cushions are resilient and can be manually reshaped for repeated use in shipping or as void fill. Local packaging and shipping stores may accept smaller cushions for reuse.
For recycling, Sealed Air operates a Foam Return Program with over 25 locations worldwide, including sites in California, Connecticut, Illinois, Kentucky, Massachusetts, New Jersey, North Carolina, and Texas in North America. The program accepts the cushions intact, without separating the foam and film. Returned materials must be clean, dry, and free of tape, labels, or cardboard, and shipments require prepayment. Small quantities of up to five bags can be dropped off during business hours, while larger volumes need prior email arrangements and placement in Gaylord boxes on pallets.
Processed foam follows two paths: in areas with infrastructure, it becomes new products like composite lumber and building materials, some used in Sealed Air's own workstations. Elsewhere, it goes to waste-to-energy facilities for burning, ensuring all returned foam avoids landfills.
The polyethylene film on Instapak should not be detached for separate recycling through store drop-off programs for plastic bags and film, as those exclude foam-bonded materials. Sealed Air's other polyethylene products qualify as #4 LDPE for such systems.
If reuse or return is not feasible, compress cushions to about 10% of their volume for garbage disposal. The cured polyurethane is inert and produces less than 1% ash in incineration, though landfilling should be avoided as the material occupies space indefinitely.
