The HZJ series is a professional shrink sleeve seaming machine that converts flat rolls of PVC or PET heat-shrinkable film into finished sleeve label rolls at up to 150 m/min. Used worldwide for beverage, food, cosmetic and battery label production — factory direct from Ruian, China.
A shrink sleeve seaming machine — also known as a shrink label gluing machine, sleeve forming machine, or shrink film seamer — takes flat rolls of heat-shrinkable film and folds them lengthwise, applying solvent adhesive along the open edge to form a continuous sealed tube. This tube is then rewound into roll format, ready for downstream printing inspection, slitting, or direct sleeve application on bottles and containers.
The HZJ series PVC & PET shrink sleeve seaming machine from Xuanhai Machine runs at up to 150 m/min with full touch-screen PLC control. An air-shaft unwinder enables fast roll changeovers with zero tools, while magnetic-powder brake tension control and dual photocell web guiding keep the film perfectly aligned for a clean, consistent center seam at every speed.
Compatible shrink film materials include PVC (polyvinyl chloride), PET (polyethylene terephthalate), PETG, and OPS. With max flat widths of 350 mm and 500 mm, the HZJ series suits a broad range of sleeve label widths — from small battery wraps to full-body beverage bottle labels. CE certified, factory direct pricing, and 12-month warranty included.

The pneumatic 3-inch air-shaft unwinder grips and releases film rolls in seconds — no tools, no core adapters. Dramatically reduces changeover downtime between production runs of different PVC or PET shrink label rolls.

A precision magnetic powder brake on the unwinder station delivers smooth, stepless tension control across the full speed range. Eliminates film stretching, neck-in and mis-registration — essential for thin PVC and PET shrink films.

Dual photoelectric sensors continuously monitor film edge position and correct lateral drift in real time. Ensures a perfectly centered, straight seam line on every meter of shrink sleeve label produced — even at 150 m/min.

All film transport rollers are precision-ground and surface-treated with anti-rust and anti-oxidation coating. Protects sensitive PVC and PET shrink films from contamination marks, scratches and static build-up during high-speed seaming.

A full-color HMI touch screen provides intuitive speed adjustment, production counters, fault diagnostics and recipe memory. Operators can set, monitor and fine-tune all seaming parameters without specialized training.

Optional dot-teeth perforation knife unit scores continuous easy-tear lines directly onto sleeve labels inline — during the seaming process. Eliminates the need for a separate offline perforating machine and shortens overall lead times.
