Pack Leader’s series of high-speed shrink sleeve labeling machines is designed for full body sleeve labeling applications, as well as neck and cap banding, tamper-evident applications. With the Pack Leader shrink sleeve labeling models differing only in size and labeling speed, the SL Series is well-suited for a wide variety of industries and applications, although the machines’ tamper-resistant “neckbander” is ideal for beverage, pharmaceutical and cosmetic companies.

Highly Efficient

All Pack Leader SL series machines utilize the most advanced shrink technology with a large touch-control screen and an advanced Programmable Logic Computer (PLC) - enabling superior labeling speed and accuracy. Speeds from 100-550 products per minute.

Simple to Use

The SL series machines are fully enclosed and feature an integrated touch-screen control panel, offering advanced job memory and troubleshooting menus. The machines’ highly efficient design enables easy operation and quick change-over for different product specifications and requirements.

Built to Last

In strict compliance with Good Manufacturing Practices (GMP) standards, the SL Series machines’ solid and steady frame is made from durable 304 stainless steel and anodized aluminum. The front acrylic interlock door is used for protection against the machine’s many high-speed moving parts, and also allows for easy operation and maintenance. The durability translates into an easy-to-maintain shrink sleeve labeling machine with a long, durable life.
