A labeling machine is a versatile equipment that labels various products or containers. These machines come in different types and configurations, depending on the label application method and label type.
A sleeve labeling machine is a specialized labeling machine that applies shrink sleeves or stretch sleeves onto containers. This post introduces some different points of labeling machine and sleeve labeling machine.
What is a Sleeve Labeling Machine
A Sleeve Labeling Machine is a type of packaging machinery used in various industries to apply shrink sleeves or labels onto containers, such as bottles, cans, jars, and other similar products. The machine is designed to streamline the labeling and packaging process, ensuring efficient and precise labeling of products.
The sleeve labeling process involves using plastic or paper sleeves (shrink or stretch sleeves) pre-printed with graphics, text, or product information. These sleeves are placed around the container, and when heat is applied, they shrink tightly onto the container’s surface, creating a visually appealing and tamper-evident label.
Working Process of Sleeve Labeling Machine:
- Container Feeding: The containers are fed into the labeling machine’s conveyor system from an input source, such as a filling line or manual loading station.
- Sleeve Application: As the containers move along the conveyor, the machine applies the sleeves around the containers. The sleeves are cut and positioned accurately on the containers using various mechanisms.
- Heat Shrinkage: After the sleeves are applied to the containers, they pass through a heat tunnel or heat shrink system. The heat causes the sleeves to shrink and tightly conform to the container’s shape, creating a seamless, 360-degree label coverage.
- Cooling and Inspection: Once the heat shrink process is complete, the containers may pass through a cooling section to solidify the labels. An inspection system may also be used to check for proper label placement and quality.
Different Points of Labeling Machine and Sleeve Labeling Machine
- Label Application Method:
- A labeling machine is a general term for machines that apply various labels to products or containers. These labels can include pressure-sensitive (self-adhesive), wrap-around, front and back, top, and more. The labeling method can vary based on the label type and the product requirements.
- A Sleeve Labeling Machine specifically applies shrink sleeves or stretch sleeves onto containers. These sleeves are pre-printed with graphics and product information and are designed to wrap around the entire container.
- Label Materials:
- Labeling machines can handle different label materials, such as paper, plastic, metallic, holographic, etc. The labels are usually pre-printed with the required information or graphics.
- Sleeve labeling machines work with shrink sleeves made of plastic (such as PETG, PVC, or OPS) or paper. These sleeves have a unique property – when heat is applied, they shrink and conform tightly to the container’s shape.
- Application Process:
- The label application process depends on the type of label and the machine’s configuration. Common methods include pressure-sensitive applications, glue-based applications, and cold glue.
- Sleeve labeling machines combine cutting, positioning, and heat application to wrap the sleeves around the containers. The heat causes the sleeves to shrink, creating a seamless and secure label.
- Types of Containers:
- Labeling machines are versatile and can be used for various containers, such as bottles, jars, cans, boxes, and more. They can handle different shapes and sizes of containers.
- Sleeve labeling machines are commonly used for containers with a circular or curved shape, such as bottles and jars. They may not be suitable for flat-sided containers.
- Labeling Accuracy:
- Depending on the machine’s technology and settings, labeling machines can offer precise and accurate label placement on the containers.
- Sleeve labeling machines can achieve high precision in label placement, ensuring consistent and aesthetically pleasing label coverage.
Conclusion
A labeling machine is a broader term encompassing machines for applying various types of labels. At the same time, a sleeve labeling machine is specifically designed to apply shrink sleeves or stretch sleeves on containers. Sleeve labeling machines are known for their 360-degree label coverage, tamper-evident seal, and high-speed application, making them popular in industries where product branding and visual appeal are crucial.
