Advantages of linerless labels

Linerless labels are labels without a liner. During printing, the graphics are first printed on the adhesive label, then a layer of silicone oil is applied to the surface of the printed adhesive label to prevent them from sticking together. Next, a layer of hot melt adhesive is applied to prevent the adhesive labels from sticking to each other. Tear lines are set on the labels for easy removal, followed by the winding process.

The silicone oil on the surface of the adhesive has a waterproof and dirt-resistant effect, protecting the graphics and information on the surface material, significantly improving printing results. The emergence of linerless adhesive labels has thoroughly reduced the environmental hazards posed by liners, meeting users’ dual requirements for economy and environmental protection. Since its introduction, it has gained widespread attention and praise, quickly becoming a hot topic in the field of adhesive label materials.

Driven by the dual forces of sustainable development trends and increasing efficiency demands, linerless label technology has matured over nearly 20 years of development, with increasingly widespread applications. The current mainstream applications of linerless labels in the market include decoration, food packaging, and thermal printing labels in the food packaging sector. Particularly driven by the rapid growth of terminal applications such as grocery stores, logistics, and fast-food outlets, the latter two have grown rapidly, with an annual growth rate of approximately 15%.

Advantages of linerless labels:

1. No liner costs: Compared to traditional adhesive labels, linerless labels have no liner, resulting in zero liner costs, achieving energy saving and emission reduction. This reduces deforestation, decreases freshwater and other energy consumption, and reduces carbon emissions. Coupled with other cost reductions, it aligns with the concept of green printing.

2. Reduced label material costs: Traditional adhesive labels often leave a certain amount of blank space between labels or at the edges for waste removal or subsequent printing tracking, increasing the area of material required by about 8%. Linerless labels have no material waste because they do not require waste removal during production. They achieve convenient removal through pre-set tear lines between labels, saving approximately 30% of material costs and reducing overall costs by about 10%.

3. Reduced transportation and storage costs: Since linerless labels have no material waste and no liners, the same size core can accommodate more labels, approximately doubling the number of labels. Compared to traditional adhesive rolls of the same size and thickness, linerless rolls can accommodate more than 50% additional labels, reducing storage space for labels, lowering logistics costs, and saving expenses.

4. Increased efficiency: With more labels accommodated on the same size core, there is less frequent need to change labels when using linerless labels, reducing downtime for label replacement during labeling processes. This effectively increases the number of labels applied per unit of time, significantly improving factory efficiency.

5. Reduced printhead wear: To prevent sticking, a layer of silicone oil is applied to the surface of linerless labels, reducing friction between the material surface and the printhead, lowering printhead wear, and saving printing costs.
