Glue Labeling Machine
What Is Glue Labeling Machine?
A glue labeling machine is a type of machine used to apply labels to products or packaging using glue as the adhesive. These machines are commonly used in industrial manufacturing on production lines to automatically apply labels to products of various shapes and sizes, increasing efficiency and accuracy.
Glue labeling machines typically have highly adjustable control systems, allowing them to be tailored to different product and label requirements. They also often incorporate sensors and other automated systems to ensure the labels are applied correctly and consistently. The use of glue as an adhesive allows for strong and long-lasting label adhesion, making it a popular choice for many industries.

The working principle of a glue labeling machine involves several steps:
Label feeding: The machine feeds labels from a roll or a stack of labels into the labeling head.
Label application: The machine applies the label to the product or packaging. This can be done either by a rotating mechanism that spins the product or packaging or by a conveyor belt that moves the product or packaging through the labeling head.
Label pressing: The machine presses the label onto the product or packaging to ensure good adhesion.
Label cutting: The machine cuts the label from the roll or stack after it has been applied to the product or packaging.
Some glue labeling machines also incorporate sensors and cameras to ensure accurate label placement and orientation, and to detect any defects or errors in the labeling process. The machine may also have adjustable settings for label size, glue application, and label placement to accommodate different products and label designs.
The gluing system of a glue labeling machine is responsible for applying the adhesive to the back of the label before it is applied to the product or packaging. There are several types of gluing systems used in glue labeling machines, including:
Roll-fed glue system: In this system, glue is applied to the label by a glue roller, which rotates through a container of adhesive. The label is then fed through a guide mechanism that ensures the glue is applied evenly across the label.
Wheel-fed glue system: In this system, a glue wheel applies the adhesive to the back of the label as it passes through the labeling head. The wheel is coated with adhesive, which is transferred to the label as it passes over it.
Spray glue system: In this system, the adhesive is applied to the label through a spray nozzle. The adhesive is atomized into small droplets and applied evenly to the label surface.
Hot melt glue system: In this system, a hot melt adhesive is applied to the label by a nozzle. The adhesive is melted and applied to the label in a controlled manner, creating a strong bond when it cools.
The choice of gluing system depends on factors such as the label material, the type of product or packaging being labeled, and the required level of adhesive strength. Some glue labeling machines may also have multiple gluing systems to accommodate different labeling requirements.
The main difference between a glue labeling machine and a normal labeling machine is the type of adhesive used to attach the label to the product or packaging.
A normal labeling machine typically uses pressure-sensitive labels, which have an adhesive backing that sticks to the product or packaging when pressure is applied. These labels are easy to apply and do not require a separate glue application process.
In contrast, a glue labeling machine applies a layer of adhesive to the back of the label before it is applied to the product or packaging. This allows for a stronger and more permanent bond between the label and the product or packaging, making it a preferred option for certain industries such as food and beverage, cosmetics, and pharmaceuticals, where label adhesion and durability are critical.
Another difference between glue labeling machines and normal labeling machines is the equipment used for applying the label. Glue labeling machines typically have specialized labeling heads with glue application systems, while normal labeling machines may have simpler labeling heads that rely on pressure or vacuum systems to apply the label.
Glue labeling machines can work with a wide range of labels, including:
Paper labels: Glue labeling machines can handle a variety of paper labels, including coated, uncoated, and glossy papers.
Film labels: Glue labeling machines can also work with film labels, such as PVC, PET, OPP, and BOPP films.
Foil labels: Some glue labeling machines are also designed to work with foil labels, such as aluminum foil or other metallic substrates.
Clear labels: Clear labels are becoming increasingly popular in many industries, and glue labeling machines can handle these labels as well.
The choice of label material depends on the product or packaging being labeled, as well as the application requirements for the label, such as resistance to moisture, heat, or other environmental factors. It is important to select the appropriate label material for each application to ensure that the label adheres properly and remains legible throughout the product’s lifespan.
When using a glue labeling machine, there are several important things to pay attention to, including:
Label material: Make sure the label material is compatible with the glue and labeling machine being used. Some labels may require special glues or equipment for proper application.
Glue viscosity: The viscosity of the glue should be appropriate for the label material and the labeling machine being used. The glue should flow easily and evenly through the labeling head without clogging.
Label placement: The label should be properly aligned and placed on the product or packaging to ensure accuracy and consistency.
Label adhesive strength: The adhesive strength of the label should be appropriate for the product or packaging being labeled. Too much adhesive can cause the label to tear or damage the product or packaging, while too little adhesive can cause the label to fall off.
Machine maintenance: Regular maintenance and cleaning of the labeling machine can help ensure the proper functioning and prevent issues such as clogging or misalignment.
Safety: Follow all safety guidelines and precautions when using the labeling machine, including proper use of personal protective equipment and adherence to machine-specific safety guidelines.
By paying attention to these factors, you can help ensure the proper functioning and effectiveness of your glue labeling machine, and produce high-quality labeled products.
