The Best Self-Adhesive Labels for E-commerce Packages – Expert Guide

It would seem that a courier label is just a sticker with a barcode. However, in e-commerce, it is the most important element of the entire logistics process. A poorly chosen label can slow down packing, peel off during transit, and in the worst case, cause the package never to reach the customer.

Which parcel labels are the best? What should you pay attention to when choosing them? We have prepared an expert guide that will answer the most important questions for e-commerce sellers.

How to choose the type of label – thermal on a roll or sheets?

A common dilemma for employees and store owners involved in shipping is the choice of label type and printing technology. The clear winner in e-commerce is thermal labels on a roll.

How do thermal labels differ from other self-adhesive labels?

Thermal labels are covered with a special heat-sensitive layer. The printer applies your shipping data to them using heat, which means you don't need ink or toner. This technology ensures speed and simplicity, helping you avoid shipping delays. In comparison, Memo Label A4 sheet labels require printing on classic laser or inkjet printers, which increases costs and slows down packing at a larger scale. It's worth choosing the label printing technology to suit your business needs – not the other way around.

What's better: labels on a roll or sheet labels? 

Sheet labels work great for a few parcels a day. However, for larger volumes, the only sensible and definitely more economical solution are roll labels, compatible with printers using thermal printing technology.

How to choose the size of a self-adhesive label for a courier company (InPost, DPD, DHL)?

E-commerce often faces the challenge: "Does this format fit parcels sent via parcel lockers and couriers?". The answer is simple, because the logistics industry has largely standardized in this regard.

What label size to choose for courier parcels? 

The market standard is now the size 100 x 150 mm labels. Such a label can easily accommodate all address data, a large and legible barcode, and QR codes. The 100 x 150 mm format is 100% compatible with the systems of the most popular companies, such as InPost, DPD, DHL, GLS, UPS, and Orlen Paczka.

If you send smaller quantities of parcels daily, A4 sheet labels will also be a good solution. Modern laser or inkjet printers allow for printing individual labels from a sheet – making it quick and convenient to label each shipment separately. We especially recommend the Memo Label A4 sheet with labels measuring 105 x 148 mm (A6 format), which matches the size of courier labels.

What about small parcels and envelopes? 

For very small items, smaller label formats can be used, provided the carrier's system allows it. However, it is often better to simply fold a standard label over the edge of the box, ensuring that the barcode remains flat and scannable.

Barcoded or QR code labels in e-commerce

Increasingly used in the e-commerce industry – mainly due to GDPR regulations and a focus on customer privacy. Barcodes or QR codes on labels are used on larger packing lines and in internal warehouse processes. These types of stickers enable process automation and order tracking in the warehouse. Codes allow for anonymization of customer personal data, but can also be used as identifiers for individual products. This system underpins the entire logistics and good organization of larger e-commerce operations.

Such markings must meet higher durability standards to allow products to be stored for a longer period without losing legibility. The best for this purpose will be thermal transfer labels on a roll — in sizes 30 x 100 mm and 50 x 30 mm. Such a format perfectly fits a barcode, a short SKU number, and possibly an abbreviated product name. For QR codes clearly visible even from a distance, larger labels 100 x 50 mm will be suitable. Thermal transfer printing technology is an ideal choice wherever durability and aesthetics are required.

How to match labels to your printer?

Even the best label won't work if it doesn't fit your equipment.

Which printers are suitable for self-adhesive courier labels?

Most 100 x 150 mm labels are wound on cores (inner tubes) that fit standard office devices. At Dalpo, you can choose the core diameter perfectly suited for your model: 25.4 mm (1 inch), 40 mm (1.5 inches), or 76 mm (3 inches). Remember that the printer technology (thermal or thermal transfer) must always match the type of labels chosen.

Does the print from a thermal printer rub off? 

Thermal print is sufficiently resistant to abrasion, making it ideal as a label for courier shipments. Over time, labels may fade, but in the standard e-commerce logistics process – which is lightning-fast – this is not an issue.

Warning stickers and branding – are they worth investing in?

A package is the only physical point of contact between e-commerce and the customer. Proper labeling therefore serves two functions here: protective and image-building. Here, UV, thermal transfer, inkjet, or laser printed labels – with high resistance and a professional appearance – will work well.

How to label delicate packages? 

Classic labels printed with "Fragile glass," "Top," "This way up," or "Do not drop" are essential when shipping delicate goods. They ensure warehouse staff and couriers know how to handle the shipment. This also streamlines the process of any potential claims with the carrier.

Is it worth ordering stickers with your own logo?

Absolutely. Personalized labels for sealing packages inside or as tamper seals on the outer carton build a professional appearance and increase your brand recognition.

Focus on less waste: Customers appreciate premium branding, especially that based on eco-friendly, paper labels. At Dalpo, you'll find solutions using kraft paper and paper with added beet fibers. These labels are perfect for industries focused on sustainability, serving as image-building stickers to enhance packaging aesthetics.
