Seiko SLP720RT and Linerless Labels: Which Roll to Choose?

The Seiko SLP720RT is a compact linerless printer that is easy to integrate. Like all thermal printers designed for linerless labels, it performs very well, provided it is fed with the corresponding linerless label roll in terms of width, diameter, and adhesive. Its advantage is its compactness: it fits into tight spaces while delivering linerless labels. Here is what it accepts and how to choose the right consumable. Subject to manufacturer eligibility.

What the Seiko SLP720RT accepts

In terms of hardware, it supports widths from 40 to 58 mm, enough to handle everything from small price tags to wide order formats. The roll can have an outer diameter of up to 102 mm, and this diameter directly affects autonomy: the larger it is, the more linear meters the roll offers, and the less frequent the reloads. The mandrels listed for compatible references are 12.5, 19, 25, 25.4, and 40 mm. Subject to manufacturer eligibility.

The compatible labels

In practice, it is fed with rolls 40 and 58 mm wide, up to 102 mm outer diameter. The width is chosen based on the intended use, then the largest allowable diameter is selected to space out reloads. These two criteria, usable width and maximum diameter, are enough to guide the choice. Subject to manufacturer eligibility.

The adhesive question

The adhesive determines the label’s hold and the cleanliness of the surface once removed. For this model, several types coexist. There is permanent adhesive, which ensures long-lasting hold on most surfaces for logistics and long-term labeling; reinforced adhesive, which maintains grip on difficult surfaces, in cold or humid conditions; and repositionable adhesive, which peels off and repositions cleanly, ideal for order labeling and surfaces to be preserved. The choice depends on the target surface and the expected label lifespan. Subject to manufacturer eligibility.

Check compatibility

Before ordering, the safest approach is to compare your exact model with the list of validated linerless rolls.
