4월
Shipping labels function as key elements within modern logistics and eCommerce because they guarantee accurate delivery operations and provide supply chain traceability. The proper selection of shipping labels becomes vital for businesses that expand their operations because it affects operational performance as well as cost efficiency and customer satisfaction.
This guide serves distributors, purchasing managers, logistics coordinators, and sourcing agents who want to learn about shipping label structure and sourcing approaches for high-volume B2B operations.
What Are Shipping Labels?
Definition
Shipping labels consist of adhesive labels that attach to packages and display important delivery information. Shipping labels generally include the recipient address and return address along with a tracking number, barcode, and shipping method. Humans and automated systems such as barcode scanners and sortation robots read these labels.
Key Elements of a Shipping Label
- Sender and recipient address
- Barcode and tracking number
- Shipping service level (e.g., standard, express)
- Package weight and dimensions
- The shipping label displays the order ID along with SKU and batch number when relevant.
Print Technology Used
- Direct Thermal (most common for 4×6 labels)
- Thermal Transfer (for longer-lasting applications)
- Office setups and hybrid environments deploy both Laser and Inkjet printing technologies.
Why Shipping Labels Matter in B2B Logistics
- Make sure shipments arrive correctly by stopping misdirected deliveries and late arrivals
- Automation becomes possible when shipping labels work with scanners as well as WMS and ERP systems.
- Real-time order tracking across supply chains becomes possible with this feature.
- Streamline Returns: Include return instructions or barcodes
- Branding support through ready-made logos or QR codes on labels.
Shipping Label Sizes and Formats
| Label Size | Common Use | Printer Type |
|---|---|---|
| 4″ x 6″ | Standard shipping label | Desktop/industrial direct thermal |
| 4″ x 8″ | International/customs docs | Wide-format printers |
| 2″ x 1″ | Product, SKU or bin labels | Mobile/compact printers |
| 2.25″ x 1.25″ | Return address or inventory | Mobile thermal |
Types of Shipping Labels by Printing Method
Direct Thermal Labels
- No ribbon, ink, or toner required
- Short-term durability (6–12 months)
- Ideal for shipping, warehousing, eCommerce
Thermal Transfer Labels
- A ribbon is necessary to apply ink to thermal transfer labels.
- Highly durable, moisture/heat/UV resistant
- Used in harsh or long-term storage environments
Inkjet and Laser Labels
- Used in office printers with sheet-fed formats
- Less efficient for high-volume logistics workflows
Core Components of a Shipping Label
Facestock
- Paper: Cost-effective, suitable for standard shipping
- Synthetic film (BOPP, PET): Water-resistant, tear-resistant
Adhesive
- This permanent adhesive maintains strong bonding capabilities on materials like cardboard, poly mailers, and shrink wrap.
- Removable: For reusable containers or temporary labeling
- Freezer-Grade: For cold storage or refrigerated logistics
Liner
- Backing paper with silicone coating enables simple peeling and feeding during label application.
- Available in rolls or fanfold formats
