Fully Automatic Shrink Sleeve Labeling Machine & Steam Tunnel (SL-150 + ST-18)

The SL-150 and ST-18 system is a professional fully automatic shrink sleeve labeling solution engineered for high-performance beverage, pharmaceutical, and cosmetic packaging. Whether you are applying tamper-evident seals to bottle caps or full-body labels to irregular containers, this setup outperforms traditional pressure-sensitive labeling with lower material costs and superior visual aesthetics. Paired with a high-efficiency steam shrink tunnel, it delivers wrinkle-free label adhesion without overheating.

At a Glance (TL;DR)

• Premium Steam Shrinking: Ensures even, wrinkle-free shrinking on delicate or irregular bottle shapes without dry-heat distortion.
• Cost-Effective Labeling: Sleeve film is significantly cheaper than adhesive stickers, providing rapid ROI for high-volume producers.
• High Scalability: Operates as a full production line up to 150 pcs/min or supports manual loading with the ST-18 tunnel for smaller setups.
• Dual Functionality: Supports both tamper-evident cap sealing and full-body label applications.

I. Key Benefits & Core Features

• Superior Aesthetic Finish: Steam shrinking provides a smoother, professional appearance that standard heat tunnels cannot match on irregular containers.
• Versatile Application: Ideal for mineral water bottling, pharmaceutical bottles, cosmetics, and food packaging cap security.
• Flexible Growth Path: Start with manual sleeve application using the ST-18 steam tunnel, and easily integrate the SL-150 automatic applicator as your production grows.

III. Frequently Asked Questions (FAQ)

Q: Why choose a steam shrink tunnel over a standard hot-air tunnel?
A: Steam shrinking is more consistent and gentler, preventing label melting or distortion while ensuring an even shrink on irregular bottle surfaces.

Q: Can I use this system for just the bottle cap?
A: Yes, this machine is widely deployed for applying tamper-evident neck bands to bottle caps for enhanced product safety.

Q: What if my production volume is low right now?
A: You can start by manually sleeve-applying labels and running them through the ST-18 Steam Tunnel, then add the SL-150 automatic applicator later as your business scales.
