Wet Glue Labeling Machine Workflow
The wet labeling process begins as bottles or tins are rolled into the machine, where a pressure belt gently guides them through the labeling pathway. As each container passes through the adhesive station, a precise application of resin glue coats the designated area. The label is then picked up by the applicator rod and smoothly transferred onto the container’s surface while it rotates, ensuring even and accurate placement. To secure the label, the end of the label receives an extra dab of adhesive, guaranteeing a firm bond throughout the container’s journey on the conveyor.
The wet glue labeling machine system is equipped with sensors that detect the presence of a container, ensuring labels are only dispensed when a bottle or tin is correctly positioned—eliminating unnecessary waste and maintaining high efficiency. The labeling speed can be easily adjusted, allowing flexible operation from low to high speeds depending on production requirements. Maintenance is straightforward, with accessible replacement parts and a simple tank change process designed to minimize downtime and maximize productivity.
How does the machine prevent bubbles and ensure a smooth label application?
Belt Pressing Mechanism for Bubble-Free Labeling
A dedicated belt pressing system applies consistent, firm pressure to each label immediately after application. This ensures every label adheres smoothly and tightly to the bottle surface, effectively eliminating bubbles or wrinkles. The result is a flawless finish that enhances both the precision of label placement and the overall visual appeal of your products.
How does the cans feeding delivery system and change tooling workin a labeling machine for different can sizes?
Various types of glue can be utilized with this machine. When switching containers, certain parts such as screws, belts, and sponges may need to be replaced. However, format changes are unnecessary for containers with similar diameters.
Flexible Container Handling
The machine features a dedicated feeding and delivery system, including a turntable for efficient can or bottle placement. When working with different container types or sizes, adjustments to the feeding components at the entry point may be required to ensure precise alignment and smooth operation. This flexibility allows for quick adaptation between production runs, making the machine suitable for a wide range of cylindrical bottles and cans across various industries.
What are the differences in print quality between wet-glue and self-adhesive labels?
Comparing Print Quality: Wet-Glue vs. Self-Adhesive Labels
When considering print quality, the gap between wet-glue (WG) and self-adhesive (SA) labels has virtually disappeared thanks to advances in printing technology. Traditionally, wet-glue labels have been produced using lithographic printing, delivering sharp, consistent results ideal for high-volume runs commonly found in food and beverage packaging.
However, self-adhesive labels have rapidly evolved. Originally limited to simpler applications such as basic price or barcode stickers, today’s SA labels are crafted with the latest combination presses, offering a wide range of graphic options and enhancements. These presses support not only litho printing but also a variety of other methods, enabling intricate designs, high-color fidelity, and special embellishments.
Leading industry experts now agree that both wet-glue and self-adhesive labels can achieve comparable levels of quality. Modern SA labels can match the precision and visual impact of litho-printed WG labels, and the choice between the two often hinges on additional factors like run length, cost efficiency, or specific container needs rather than pure print excellence.
