4 x 6 Thermal Shipping Labels 12000 Fanfold Labels - High Capacity

In this review of the 4 x 6 Thermal Shipping Labels from SJPACK the bottom line is simple: these are a high-capacity, low-cost option for businesses that need bulk thermal labels for standard shipping tasks. The pack delivers 12 stacks (1,000 labels per stack) for a total of 12,000 fanfold labels, and that sheer quantity is the single biggest reason to buy. The labels are designed for direct thermal printers and cover common engines used in shipping and fulfillment, making them a practical choice for high-volume mailers.

Key Features

• Size 4 x 6: The standard shipping label dimensions fit most carrier templates for USPS, UPS and FedEx without trimming or scaling issues.
• 12,000 labels total: Twelve stacks of 1,000 labels each reduce reordering frequency and keep fulfillment lines moving with fewer interruptions.
• Wide printer compatibility: Works with many direct thermal printers such as Zebra, Rollo and Munbyn, so integration with common shipping hardware is straightforward.
• Perforated backing: A perforated line between each label makes it easy to tear and use individual labels quickly on a busy packing table.
• Strong adhesive: The glue is formulated to stick reliably to corrugated boxes and envelopes used in typical shipping environments.
• Direct thermal stock: No ribbon or ink required, which simplifies printing and lowers ongoing consumable costs.

Who It's For

These labels are best for small to medium e-commerce sellers, warehouse pack stations, and shipping centers that use direct thermal printers and want to minimize supply handling. The large quantity and fanfold packaging suit continuous label runs and batch printing for carriers like FedEx.

Shoppers who need premium thickness, long-term archival durability, or compatibility with thermal transfer printers should look elsewhere. Also note these labels do not support Dymo machines, so businesses standardized on that brand will need a different SKU.
