A bottle sleeve machine, or shrink sleeve applicator, is an automated packaging system that applies plastic film sleeves (labels or seals) onto bottles, which are then shrunk to fit via a heat tunnel. These machines, used for tamper-evident bands, full-body labels, or bundling, utilize synchronized motors, PLC controls, and photoelectric cells for high-speed, precise application, commonly seen in food, beverage, and pharmaceutical industries.
Key Components and Types
Applicator: Feeds and cuts the heat-shrinkable material (usually PVC, PETG, OPS, or PLA) from a continuous reel into individual sleeves.
Heat Shrink Tunnel: Uses steam or hot air to shrink the sleeve, creating a snug fit around the container.
Types: Machines can be linear or rotary, catering to different production speeds and bottle shapes.
Common Applications
Full Body Sleeving: Covers the entire bottle with branding, often used for oddly shaped containers.
Tamper-Evident Banding: Applies a safety seal over the bottle cap/closure.
Multipack Sleeving: Bundles bottles together for promotional packs.
Key Features
High-Speed Application: Many modern systems use brushless motors to reach high production speeds.
PLC Control: Programmable Logic Controllers manage the feeding, cutting, and positioning of labels.
Material Compatibility: Designed to handle various heat-sensitive materials that form around the object when heated.
