Best Shipping Supplies: Boxes, Tape, Labels Compared
The right shipping supplies prevent damage claims, reduce costs, and look professional. USPS provides free Priority Mail and Flat Rate boxes — order at usps.com before buying anything. For everything else, Scotch Heavy Duty packing tape ($0.08/yard) outperforms budget tape on every metric, thermal labels ($0.02-$0.04 each) save money versus inkjet labels for anyone shipping 10+ packages monthly, and water-activated kraft tape provides the strongest seal while being fully recyclable. Uline, Amazon, and Staples are the three best supply sources depending on volume.
This guide compares every category of shipping supplies with specific product recommendations, pricing, and where to source them.
Key Takeaways
- Free USPS Priority Mail and Flat Rate boxes eliminate the biggest packaging cost for many shippers.
- Scotch Heavy Duty packing tape is the reliability benchmark — its 3-mil thickness holds on all box types.
- Thermal labels at $0.02-$0.04 each beat inkjet/laser labels for anyone shipping regularly.
- Water-activated kraft tape has seen 43% adoption growth since 2023 and provides the strongest, most tamper-evident seal.
- Proper supplies prevent damage claims — the $2-$5 cost of quality materials avoids $50-$500+ losses.
Methodology
Products are evaluated on four criteria: seal strength (holds boxes closed under stress), durability (resists temperature changes, moisture, and handling), cost per unit at typical shipping volumes, and availability (can be purchased quickly from major retailers). Where possible, we reference published testing data and carrier packaging requirements.
Boxes
Free USPS Boxes
Before spending money on boxes, check if free USPS packaging meets your needs:
| Free USPS Box | Dimensions | Service Required |
|---|---|---|
| Small Flat Rate Box | 8.625” x 5.375” x 1.625” | Priority Mail |
| Medium Flat Rate Box (top) | 11.25” x 8.75” x 6” | Priority Mail |
| Medium Flat Rate Box (side) | 14” x 12” x 3.5” | Priority Mail |
| Large Flat Rate Box | 12.25” x 12.25” x 6” | Priority Mail |
| Priority Mail Box 4 | 7” x 7” x 6” | Priority Mail |
| Priority Mail Box 7 | 12” x 12” x 8” | Priority Mail |
Order at usps.com/shopstore (free shipping, arrives in 5-7 days) or pick up at any post office. These boxes can only be used with Priority Mail services — using them with Ground Advantage or other carriers violates USPS regulations.

Box Size Selection Tips

- Keep a stock of 3-4 common sizes rather than one-size-fits-all

- Cellophane tape: No adhesive strength on cardboard
- Electrical tape: Not designed for packaging, creates a poor seal
For detailed tape comparisons, see best packing tape and materials.
Labels
Thermal Labels (Recommended for Regular Shippers)
Thermal labels require a thermal printer but eliminate ink costs entirely. At 10+ packages per month, the printer pays for itself within 2-3 months.
Best Thermal Labels: Rollo Direct Thermal Labels
- 4” x 6” standard shipping label size
- Compatible with Rollo, DYMO, Zebra, and other thermal printers
- Pricing: approximately $0.02-$0.03 per label (500-pack)
- Adhesive peels cleanly, no curling or jamming
Best Budget Thermal Labels: Amazon Basics or BETCKEY
- Same 4” x 6” size, compatible with most thermal printers
- Pricing: approximately $0.01-$0.02 per label in bulk
- Quality is acceptable for most shipping needs
For thermal printer recommendations, see best thermal label printers.
Inkjet/Laser Labels (For Occasional Shippers)
If you ship fewer than 10 packages per month, inkjet or laser labels avoid the upfront printer cost.
Best Inkjet/Laser: Avery 5126 or Avery 8126
- 2 labels per sheet, 8.5” x 5.5” each
- Compatible with all inkjet and laser printers
- Pricing: approximately $0.10-$0.15 per label
- TrueBlock technology hides printed text underneath
Label-Free Alternative: Half-Sheet Paper + Tape
Print your label on regular paper, cut to size, and tape to the box with clear packing tape. This works in a pinch but looks unprofessional and the tape can yellow or peel.
Cushioning Materials
Best Cushioning Options
| Material | Protection Level | Cost | Eco-Friendly | Best For |
|---|---|---|---|---|
| Bubble wrap (large bubble) | High | ~$0.03/sq ft | No (recyclable) | Fragile items, electronics |
| Bubble wrap (small bubble) | Medium | ~$0.02/sq ft | No (recyclable) | Surface wrapping, gap filling |
| Kraft paper (crumpled) | Medium | ~$0.01/sq ft | Yes (recyclable) | Void fill, light cushioning |
| Air pillows | Medium | ~$0.02/pillow | Partially | Void fill, light items |
| Foam-in-place | Very high | ~$0.50-$2.00/bag | No | High-value fragile items |
| Packing peanuts | Medium | ~$0.15/cu ft | Partially (starch-based) | Void fill, irregular shapes |
| Honeycomb paper wrap | Medium-High | ~$0.05/sq ft | Yes (recyclable) | Eco-friendly alternative to bubble wrap |
The 2-inch rule: All items should have at least 2 inches of cushioning material between the item and every wall of the box. This is the standard carriers use when evaluating damage claims — insufficient cushioning is the most common reason for claim denial. See how to ship fragile items for complete packing guidelines.
