Sleeve Labeling Machine-Zhangjiagang Grandee Machinery Co., Ltd.

Sleeve labeling is a packaging process where a heat-shrinkable or stretchable plastic film (typically PVC, PET, or OPS) is wrapped around a container and then shrunk tightly via heat or steam to conform to its shape. It's most suitable for irregularly shaped containers (like curved bottles or cans), products requiring 360-degree decorative graphics, and tamper-evident packaging in the food, beverage, personal care, and pharmaceutical industries.

Yes, our standard sleeve labeling system includes a steam shrink tunnel as the core heat source. Steam is particularly effective for achieving a tight, uniform shrink on irregularly shaped containers and heat-sensitive products, as it provides gentler and more even heat distribution compared to hot-air tunnels. We can also adjust the steam flow, temperature, and tunnel length to match your specific bottle material and line speed.

Yes, our machine is designed to handle both full-body sleeves and partial sleeves such as neck bands or waistbands. The changeover between the two applications is tool-less and can be completed within 5–10 minutes by adjusting the film feeding guide, cutting length, and applicator mandrel diameter. We also offer a programmable memory function that stores your settings for different sleeve sizes, ensuring consistent repeatability.

The labeling speed for 330ml PET bottles on our sleeve labeling system is determined by several key parameters:
Standard round bottles (smooth circumference): Our high-speed servo-driven model achieves up to 300 BPM under optimal conditions, with a stable operating speed of 250–280 BPM for consistent quality.
Irregular or oval shapes: For nonstandard bottle contours, the speed may be slightly lower, typically 180–220 BPM, to ensure accurate sleeve positioning and prevent wrinkling.
Bottle height and sleeve length: Shorter sleeves (e.g., full-body vs. neck-band) allow higher speeds; we run extensive tests to set the optimal speed for each bottle design.
Shrink tunnel integration: The conveyor speed is synchronized with the labeling head and the shrink tunnel. The overall line speed is matched to the tunnel’s dwell time to guarantee perfect shrinkage, so the total line speed is essentially the same as the labeling head speed.

The machine accommodates irregular bottle shapes through several key engineered features:
Adjustable In-Feed & Guiding System: The conveyor and adjustable guides can be easily reconfigured to stabilize and center irregular containers during the sleeving process.
Dual-Positioned Center Mandrel: A fixed central guide pillar ensures stable label feeding and smooth insertion, minimizing misalignment even on curved or asymmetric bottles.
Precision Cutting & Synchronization: The rotary cutter works in sync with the servo-driven bottle divider to ensure accurate sleeve cutting and placement, maintaining high precision on non-standard shapes.
Specialized Shrink Tunnel: For irregular contours, we recommend a steam shrink tunnel, which provides uniform heat distribution and delivers a smooth, wrinkle-free finish on complex surfaces. The tunnel's zoned temperature control also accommodates varying label shrinkage rates.
Tool-Free Changeover: For significantly different bottle profiles, the machine supports quick, tool-free changeover of key components, minimizing downtime

The changeover time for our fully automatic shrink sleeve labeling line with shrink tunnel is highly efficient, thanks to several design features:
Diameter adjustment: Adjusting the guide rails and center mandrel for a different bottle diameter takes approximately 5–8 minutes using quick-release knobs and digital position indicators.
Height adjustment: Changing the bottle height (if the diameter remains the same) requires only a 2–3 minute height setting via the PLC touchscreen, with no mechanical parts to replace.
Complete tooling change (if the new bottle shape requires a different mandrel or cutter assembly): The full swap, including re-calibration, typically takes 15–20 minutes.
Shrink tunnel adjustment: Temperature and air flow settings are stored in the PLC recipe; recalling a pre-saved recipe for the new bottle takes less than 1 minute.
In total, a typical complete changeover from one standard round bottle to another (different diameter and height) is under 15 minutes. For significantly irregular shapes requiring different mandrels, allow 20–25 minutes for a thorough setup and firstsample check. All adjustments are guided by on-screen instructions and scales, minimizing trial-and-error.
