Types of Shrink Sleeve Label Applicators

Share This Post

Shrink sleeve label applicators put shrink sleeve labels on products or packaging. The market for these machines is set to hit $2.5 billion by 2030, growing at 6.5% each year.

For business owners, managers, and packaging pros, understanding these applicators is key. It helps you boost efficiency, keep product quality up, and stay ahead in the market.

This guide breaks down the main types of shrink-sleeve label applicators, giving you the info you need to make smart choices for your packaging process.

Let’s dive into each type to see what they offer and where they might fall short.

Manual Shrink Sleeve Label Applicators

Manual shrink sleeve label applicators let operators apply shrink sleeves by hand. They can label up to 200 bottles an hour. The labelling speed depends on product shape, film thickness, and label length.

These applicators use heat and tension to wrap the sleeve around the product to create a seamless finish.
They come with safety features, including emergency stops and motion detectors.

These machines aren’t just basic tools; they’ve kept up with industry trends. One such trend is downgauging, which uses thinner films to save on materials and costs. This shift has led to a need for more precise cutting systems and better control.

Recent upgrades, like SMART human-machine interface (HMI) technology, have taken these applicators a step closer to Industry 4.0. HMI tech gives real-time data and insights into system performance.

Main Components

Sleeve Dispenser: Holds sleeve roll, ensures smooth feeding.
Sleeve Cutter: Cuts sleeve to size.
Applicator Head: Positions sleeve onto the container.
Heat Tool: Provides temporary shrinkage or wrinkle smoothing (heat gun, wand).
Stand: Offers stability and ergonomic benefits (height adjustment, foot pedal).
