Wholesale guide to 100 × 70 mm courier dispatch labels: barcode scanning, carton adhesion, artwork proofing, cost per accepted label and RFQ checklist.
A shipping label is a small component with a surprisingly large job. It must tell a handler where a parcel belongs, survive the packing line, and remain readable when a box arrives at a sorting hub. When a label lifts at a corner or a barcode fails, the resulting rework can cost more than the label itself.
For ecommerce brands, manufacturers, warehouses and distributors, the right question is not simply “How much is a hundred stickers?” It is which label construction and artwork will produce the lowest cost per successfully identified parcel? This guide explains what to specify, what to test, and how to request a useful quotation. It is relevant to buyers worldwide and to businesses dispatching from Siliguri, the Dooars, North Bengal and across India.
Biolastic lists a custom printed courier address / dispatch label, described as 100 × 70 mm, rectangular, unlaminated self-adhesive paper, with CMYK digital printing for parcel and corrugated-carton use. The listing describes a custom print-and-cut service and optional application subject to a separate quotation and surface suitability. It is a quote-only catalogue item; any displayed quantity tiers are indicative, not a promise of current stock, final landed pricing or turnaround.
This is not evidence that Biolastic operates a carrier-integrated label generator, prints unique tracking numbers from customer databases, supplies thermal-direct rolls, or guarantees international shipping. Ask separately if your workflow requires any of those capabilities.
A plain dispatch-address sticker can carry the recipient name, address, contact instructions and order reference. A carrier waybill may additionally need a carrier-issued barcode, service code, routing fields and a prescribed template. A GS1 logistic label is a different standardised identification system, typically used for logistics units such as pallets.
GS1 identifies the Serial Shipping Container Code (SSCC) with Application Identifier (00). Its official guidance explains that the SSCC identifies a logistic unit and links physical movement to electronic shipment information. That does not make an ordinary ecommerce tracking number an SSCC. See GS1's official logistics-label explanation and GS1 UK on SSCC labels.
Before preparing artwork, ask the carrier or fulfilment platform for the exact approved label format. A 100 × 70 mm label is a catalogue size, not a universal carrier standard. Some services require another dimension or layout. Never shrink a carrier barcode merely to make it fit.
The finished sticker has 7,000 square millimetres of area, but not all of that is printable information space. Trimming tolerance, margins, address lines and barcode clear areas compete for room.
A practical layout review should cover:
| Zone | What to verify |
|---|---|
| Recipient block | Full name, street, locality, city, state and postal code remain legible |
| Sender / returns | Correct return address and customer-service details if required |
| Reference fields | Order, SKU, carton or dispatch reference is unambiguous |
| Barcode | Correct symbology, payload, dimensions and quiet zones for the carrier |
| Handling information | Only the approved symbols or instructions appear |
| Trim and margins | No critical text or barcode area touches the cut line |
A two-line address that looks elegant on a monitor may overflow when a customer enters a long village name, apartment number or international postal address. Test worst-case data, not just a short sample. Include Bengali, Hindi or other relevant scripts where the shipping workflow requires them, and verify font rendering in the actual printed proof.
For shipments from Siliguri to nearby districts, correct locality and PIN-code data matter just as much as the city name. For cross-border shipments, do not assume an Indian domestic template covers customs, telephone, country and carrier-specific fields.
Barcode reliability depends on more than dark bars. The encoded data must be correct, the symbol must be large enough, and the scanner must recognise it under real handling conditions.
GS1's barcode placement guidance warns against placing symbols across seams, folds, flaps, edges and rough surfaces. Its transport-label guide describes quiet zones, barcode orientation and print-quality checks for GS1 logistics applications. These are useful principles, but do not substitute GS1 pallet-label dimensions for your courier's own requirements.
Before approving a bulk order:
1. Generate the barcode using the authorised carrier or warehouse system.
2. Confirm that its human-readable reference matches the encoded value.
3. Print the complete label at the intended physical size, without automatic scaling.
4. Scan multiple proofs with the devices actually used at dispatch and receipt.
5. Apply the proof to the filled package and scan again after folding, stacking and handling.
6. Document the pass/fail criteria, including who approves revisions.
If the barcode scans from a flat sheet but fails on a carton, inspect folds, tape overlap, glare, creases and surface texture before blaming the printer. A label is not validated until it works on the package.
The cited Biolastic courier item uses unlaminated self-adhesive paper. Paper can be appropriate for clean, dry cartons in a suitable dispatch environment, but it should not automatically be described as waterproof, weatherproof, freezer-safe or abrasion-proof.
For long journeys, exposed deliveries or poly-mailer applications, ask what adhesive and face stock are appropriate. A laminate may protect some printed surfaces, but the full construction still needs testing. Adhesive performance depends on the substrate, dust, pressure, temperature, surface energy and storage conditions.
Try the label on actual corrugated board, kraft paper, printed cartons and flexible mailers where relevant. Check for lifting corners, curling, smearing, tearing and unreadable text. Keep a control sample from each approved print batch.
There are two very different purchasing workflows.
Static preprinted labels carry repeated information such as a sender address, warehouse name or return instruction. They can be ordered in a common artwork and used as needed.
Variable-data labels carry a different recipient, order number or barcode on each piece. They require data handling, print-file generation, reconciliation and checks to ensure one parcel does not receive another customer's label. The Biolastic catalogue entry does not confirm variable-data capability. If that is your requirement, specify it explicitly and obtain written confirmation before sharing any personal shipment data.
Avoid emailing unprotected spreadsheets of customer addresses without an agreed data-transfer and retention process. The brand or shipper remains responsible for lawful handling of customer information and the accuracy of dispatch data.
A useful comparison includes rejected labels and handling, not only the quoted unit price.
Effective label cost = total delivered label cost ÷ accepted usable labels.
Illustrative example only: a fictional order of 1,000 labels costs ₹3,000 delivered, and 970 pass the agreed inspection. The effective cost is ₹3,000 / 970 = ₹3.09 per accepted label. This is not a Biolastic price or measured rejection rate.
If the operation also spends ₹0.80 per label on manual application, include that labour in a fuller cost-per-dispatch calculation. If a bad label causes a parcel to be relabelled, include the rework time, new materials and any carrier charges. For a warehouse dispatching thousands of parcels, a small difference in accepted-label yield can outweigh a small difference in sticker quotation.
Compare like with like: material, dimensions, colour, number of designs, barcode requirements, proofing, packaging, taxes, freight, application method and lead time. Do not compare a generic blank thermal roll with a customised CMYK paper sticker as if they were interchangeable.
Address text becomes too small. Shorten nonessential wording, change hierarchy and test the longest likely address. Never sacrifice required carrier fields.
Barcode fails after carton sealing. Keep the symbol and quiet zone away from tape seams, folds and edges. Verify final applied placement.
Label corners lift from dusty cartons. Clean representative surfaces and test adhesive compatibility, pressure and dwell time. A stronger-looking paper alone does not solve adhesion.
Ink rubs or smears. Confirm printing process, curing or drying and resistance to expected friction and humidity. Request a physical sample.
Recipient and tracking code mismatch. Treat label data as controlled production information. Use order-to-label reconciliation and independent checks where appropriate.
Courier rejects the label format. Return to the carrier's current template and barcode rules rather than modifying the artwork by eye.
Send the supplier a specification that can actually be quoted:
We require custom dispatch labels for [carton / mailer surface]. Proposed finished size: 100 × 70 mm or carrier-approved alternative. Material: [requested face stock and adhesive]. Print: [static CMYK artwork / variable data, if available]. Quantity: [per design]. Include the approved carrier template, barcode symbology and sample data, destination city/country, exposure conditions, application method and required delivery date. Please confirm proofing, sample tests, data handling if applicable, MOQ, tax, freight, lead time and acceptance criteria.
Buyers in Siliguri, Jalpaiguri, Bagdogra and the wider North Bengal region can add their delivery pincode and sample packaging photographs. Overseas buyers should request explicit confirmation of export feasibility and applicable commercial documentation; an online catalogue entry alone is not an export commitment.
The best dispatch label is the one that remains legible, correctly matched and scannable through the journey it was designed for. Start with the carrier's requirements, then select the material and printer workflow. Test on filled cartons, not only on a proof sheet.
Ask Biolastic for a courier dispatch label sample and wholesale quotation. Share your label artwork, carrier template, pack surface, quantity and delivery destination. Biolastic can then confirm the available construction and current quotation terms.
