Label applicators are essential tools in the packaging industry, allowing for efficient and accurate labeling of products. In this response, I will delve into two popular types of label applicators – tamp applicators and wipe-on applicators – and explain how they work in detail.
1. Tamp Applicators:
Tamp applicators utilize a small device, known as a tamp pad or tamp blade, to apply labels onto products with force. The process begins with a label being dispensed from a roll or a magazine onto the tamp pad. The tamp pad is then positioned above the product, and as the product moves along a conveyor, the tamp pad moves downward, applying pressure to push the label onto the product's surface.
The tamp pad is designed to conform to the shape of the product, ensuring that the label adheres smoothly. The force exerted by the tamp pad creates a seal between the label and the product, ensuring a secure attachment. Tamp applicators are commonly used for round or irregularly shaped products, where precision and accuracy are crucial.
I have personally used a tamp applicator in my wine bottling process. The tamp pad gently pressed the label onto each bottle, ensuring a professional and uniform appearance. The force applied by the tamp pad was carefully calibrated to avoid damaging the delicate glass bottles while still ensuring a strong bond between label and bottle.
2. Wipe-On Applicators:
Wipe-on label applicators, as the name suggests, utilize a brush or a pad to sweep the label onto the product's surface. The label is dispensed from a roll or a magazine and passes over the brush or pad, which is typically made of soft material like foam or rubber. As the product moves along the conveyor, the brush or pad comes into contact with the label, pressing it onto the product.
The brush or pad has a dual purpose – it not only applies pressure to ensure proper adhesion but also helps smooth out any wrinkles or air bubbles that may have formed during the application process. This ensures a neat and professional label finish. Wipe-on applicators are commonly used for flat or rectangular-shaped products, such as boxes or packages.
During my brewing days, I used a wipe-on label applicator for labeling my beer bottles. The soft foam brush gently pressed the label onto each bottle, providing a consistent and professional look. It was important to ensure that the brush was kept clean and in good condition to avoid any smudging or misalignment of the labels.
Label applicators play a crucial role in the packaging industry, allowing for efficient and accurate labeling of products. Tamp applicators use a small device to forcefully push labels onto products, ensuring a secure seal. Wipe-on applicators utilize a brush or pad to sweep labels onto product surfaces, providing a neat and professional finish. Both types of applicators have their specific uses depending on the product shape and labeling requirements.
