Rotary Labeling Technologies Explained

Pressure-Sensitive Labelers

Pressure-sensitive labeling technology is a pivotal labeling technology in modern manufacturing due to its versatility and ease of operation, particularly in high-speed applications. This method uses labels often referred to as auto-adhesive or pressure-sensitive which have pre-applied adhesive. The adherence to products is achieved when pressure from brushes and rollers is applied, eliminating the need for solvents or heat. Gernep’s Soluta is Gernep’s P-S labeling Machine is an excellent cost-effective choice for high-speed

and large-scale production environments. Known for its adaptability, the Soluta labeler can handle a wide range of product sizes and label designs, making it ideal for industries with diverse packaging needs like cosmetics and food. This flexibility is coupled with user-friendly operation, ensuring quick changeovers and minimal downtime.

Pressure-Sensitive technology has become a preferred choice across various sectors, including food, beverage, cosmetics and pharmaceuticals for several reasons.

Hot-Melt Labelers

Hot melt labeling technology featured in Gernep’s Rollina or Rollfed, involves applying a hot glue to secure a paper label onto a container. This method is suitable for high-speed requirements and can use either cut & stack (Rollina) or roll-fed (Rollfed) labels. This process provides the advantage of strong adhesion and durability, making it ideal for beverage and chemical industries where product handling can be rigorous. Labels applied using hot-melt glue are resistant to moisture, temperature variations, and rough handling,

which are common conditions in these industries. This ensures that labels remain intact and readable throughout the product’s lifecycle, from manufacturing to consumer use. Additionally, the robustness of hot melt labels is particularly beneficial for products stored in challenging environments, like refrigerators or outdoor storage, common in the beverage and chemical sectors.

Cold Glue Labelers

Cold glue technology involves applying a water-based adhesive to a label before attaching it to the container. This method is often preferred for glass bottles and is popular in the beverage industry, particularly for wine and beer labeling. The advantages of cold glue labeling include lower costs and a reduced environmental impact. 

Gernep offers cold glue labeling solutions, such as the Gernep Labetta, which are designed for precision and

efficiency. It’s cost-effective solution that also offers aesthetic appeal. Glass bottles and jars often feature a traditional, high-quality look that align with the branding typically desired in the wine and spirits industry. Additionally, cold glue labels are easily removable, making them convenient for glass recycling, an important consideration in these environmentally conscious industries.

Advanced Labeling Solutions for Industry Trends

The choice of the right labeling method – pressure-sensitive, hot melt, or cold glue – is crucial to smooth-running operations. A high-end machine with the correct choice of labeling technology ensures consistent and accurate label application – essential for maintaining product quality and brand image. The right machine will provide efficiency gains by positively impacting downtime & maintenance. Looking ahead, the trend in the manufacturing sector is more flexible, efficient, and environmentally friendly labeling systems.
