Catalog evidence reviewed October 2, 2026 · U.S. packaging buyers
Compare Uline packing peanut alternatives by the material your operation needs and the volume you intend to buy. Packrift’s listed options include 7- and 12-cu-ft corn-starch loose fill and 7-cu-ft virgin polystyrene loose fill. Match the packing requirement first, then compare the full delivered order.
Start with your current loose-fill specification
Use the Uline model or product link from your reorder record to identify the material and listed package volume. Include the carton, item, any inner wrapping and the way your team packs it. A change of loose-fill supplier should preserve the requirements of that complete packing method.
Material is a purchasing choice to resolve before price. The corn-starch and virgin polystyrene listings below are different materials. A material name alone does not establish certification, disposal instructions or suitability for a particular product. If your customer or purchasing policy requires documentation, ask for the applicable product documentation before choosing.
What to put on a comparable quote
| Requirement | Record from the current order | Why it changes the comparison |
|---|---|---|
| Material | The specified loose-fill material and any required documentation | Corn starch and virgin polystyrene are separate choices. |
| Nominal volume | Cubic feet per listed item and the total volume required | The number of packages alone does not describe the amount purchased. |
| Packing method | Carton, item, inner packaging and existing packing instructions | Confirm that the candidate works in the complete package. |
| Receiving and storage | Delivery address, receiving needs and space for the order | Include the actual delivery requirements and replenishment quantity. |
| Order cadence | Typical usage and the next run or reorder interval | Compare a useful purchase quantity instead of an arbitrary single item. |
Uline’s starch-peanut category includes 7- and 12-cu-ft formats, which gives a nominal-volume comparison to organize. Its S-1128 white polystyrene listing specifies recycled content; Packrift’s 7NUTSW listing specifies virgin polystyrene. Equal listed volume does not establish the same composition or a model-specific replacement.
Packrift material and volume options
The table uses material and nominal volume from the catalog records. It does not establish equivalence to a Uline model. Open the exact product for its current order details, price and availability.
| Packrift option | Listed material | Listed nominal volume |
|---|---|---|
| 7NUTSB — corn-starch loose fill | Corn starch | 7 cu ft |
| 7NUTSW — polystyrene loose fill | Virgin polystyrene | 7 cu ft |
| 12BNUTS — corn-starch loose fill | Corn starch | 12 cu ft |
For a corn-starch requirement, compare the 7-cu-ft and 12-cu-ft options by the amount needed and the resulting delivered order. For a virgin polystyrene requirement, start with 7NUTSW. Equal volume across different materials does not establish equal packing performance.
Compare cubic feet, then the quantity you will purchase
If each order unit supplies the listed volume, an equal-volume comparison is 84 cu ft: 12 × 7 cu ft or 7 × 12 cu ft. For the two corn-starch listings, that creates a common nominal-volume basis. It is a calculation for comparing orders, not a recommendation to buy that much.
For a requirement of 24 cu ft, two 12-cu-ft items total 24 cu ft. Three 7-cu-ft items total 21 cu ft and fall short; four total 28 cu ft. If both corn-starch formats suit your operation, compare the delivered totals and whether you can use and store the extra 4 cu ft. Confirm the listed volume per order unit on the product or quote before placing the order.
Add merchandise, shipping and required receiving charges, then divide the total by the nominal cubic feet purchased. Treat tax consistently. The Uline shipping-cost worksheet can organize the delivered comparison. Record the physical volume separately from the number of bags or packages on each supplier’s quote.
Check usage in your actual cartons
Nominal purchase volume does not tell you how many orders a product will pack. Record the amount used with a representative item and carton under your approved packing instructions. Include the inner materials your process already requires. Validate the completed package before replacing the current loose fill.
If the item needs a different protective format or a documented packing method, keep that requirement. Do not force a loose-fill substitution because a listing has a lower price. The broader Uline alternatives comparison covers supplier selection when loose fill is part of a mixed packaging order.
Request the material and volume your next order needs
Send the Uline model or product link, required material, total nominal cubic feet, typical cartons, order frequency and delivery address. Include any required documentation and receiving services. Ask for the order quantity and total supplied volume to be stated together in the quote.
Questions before switching
Are corn-starch and polystyrene packing peanuts interchangeable?
Their listed materials differ. Keep the material and packing requirements your operation uses, then evaluate a candidate in the complete package. Equal cubic-foot quantities do not establish equal performance.
How do I compare 7-cu-ft and 12-cu-ft options?
Use total nominal volume and the actual whole-item order. For example, 12 × 7 cu ft and 7 × 12 cu ft both total 84 cu ft. For a 24-cu-ft need, two 12-cu-ft items total 24 cu ft, while four 7-cu-ft items total 28 cu ft. Compare delivered cost after confirming the order units.
Does a corn-starch listing prove a disposal or environmental claim?
No. This comparison identifies the catalog material and volume only. Request the specific product documentation and applicable disposal instructions if those requirements affect your purchase.
Packrift is an independent seller and is not affiliated with Uline. No model equivalence, environmental certification, packing performance or delivered saving is established by this comparison. Confirm current product details, order units and delivered charges before ordering.
