One-Stop Solution for Shrink sleeve film production
Shrink Film: Continuously rising (4.5–5.5% CAGR). Driven by e-commerce logistics and lightweighting as a replacement for cardboard boxes. Expected to evolve toward single-material recyclability.
In-Mold Labels (IML): Significantly rising (5.5–6.5% CAGR). Fueled by strict environmental regulations (same-material recycling) and high-end 360° printing demand. Set to exceed 60% penetration in key sectors like dairy.
Self-Adhesive Labels: Structural decline (growth slowing to 2–3%). Mid-to-low-end segments are being replaced by IML and direct printing. Growth will remain in high-end, functional applications (e.g., logistics, anti-counterfeiting,wine).
Key Conclusion: The future market belongs to eco-friendly (easy to recycle) and lightweight (cost-saving) solutions. Shrink film and IML are set to capture market share from traditional paper boxes and self-adhesive labels.

The real-time mornitoring system application
Once the measure width exceed the tolerance,
It will automatically adjust into the range.
① Current deviation of the width measurement sensor, range ±3mm. If the material edge is centered on the sensor, the deviation is 0.
② Torerance alarm threshold: alarms trigger when left/right deviation exceeds this threshold.
③ Torerance alarm switch turn on automatically.
Key advantages of Polly Automatic’s seaming machine
1.Independent unwind/rewind servos
Better control, easier operation. Single-servo systems can't compare.
2.Large diameter 800mm unwind for large rolls
800mm Max unwind diameter. Larger than competitors' 500mm. Fewer roll changes, higher productivity.
3.Easy-to-Operate Tension Curve
implified Roll Tension Management
One key Homing
Auto-origin positioning for pressure wheel & clamping plate. No manual alignment needed.
5.Jog press buttons
Dual jog buttons for easier setup, web replacement & glue change.
6.Reasonable twin glue nozzles design
Twin-nozzle design: one for coating, one for dispensing. More uniform, no overflow. The syringe and the double nozzles are more likely to cause the glue to overflow and mess
7.Servo-controlled glue with speed synchronization
Speed-synchronized glue dispensing.Digital glue adjustment on HMI. Perfect seams, no mess.
8.EPC error correction system
Ultrasonic EPC systems maintain seam accuracy within =0.5mm even a sustained speeds of 400-450 meters per minute.
9.Shutdown by the counting meters.
Input desired rewinding length, the machine to stop automatically once reached,no need for operators to keep watching or to manually shut down.
11.Automatic-stop on the roll end
when the unwind diameter reach 110m, it will be stop automatically.
12.Automatic-seaming width adjustment system
Auto seaming width adjustment. Input size, instant change within 1 min. EPC ±0.5mm precision.
13.Automatic-seaming line offset device
Instant seaming position adjustments from middle to edge
14.Easy tear line & Trim edge removal, micro hole device. Easy-operate trim blades, tear line devices & micro-hole needles blades.
15.Oscillated rewind & strobe light for inspection
Left-right oscillation,smaller, tighter rolls.Shift left-right. Reel tighter.Strobe light for post-seam print defect image inspection.
16.Automated digital HMI
Easy-operate HMI. A processes controlled.
17.Extra Option hot melt device
Some customer request hot melt glue to gluing the seam, we can add addtional hot melt device as picture.
18.Air blower inside
Automatic blower, enabling the seaming banding adhesive to dry quickly
Key pain points of high-speed sleeve Seaming Machines as reported in the market
1.Offset of the folded edges during high-speed operation When the speed exceeds 150m/min, the EPC correction system often responds sluggishly, causing inconsistent seaming widths.
Polly's solution: Chose top brand Ultrasonic EPC systems maintain seam accuracy within 0.3mm even at sustained speeds of 400-450 meters per minute.
2. Tension fluctuations caused by the appearance quality of the film roll.
Poor roll quality (uneven ends, loose edges) forces constant tension adjustments, resulting in wrinkles or tears.
Polly's solution: Independent unwind/rewind servos to control, easier operation.
3.Uniformity challenge of the gluing system High-speed glue application often leads to splashing or intermittent glue lines; users demand servo-driven precision systems.
Polly's solution: Speed-synchronized glue dispensing.Digital glue adjustment on HMI.Perfect seams, no mess.
4. The automation level is not high.
A large amount of manual adjustment is required, and the training time is long.
Polly's solution:We chose six servo motors and 6 stepping motor controls in total, one hour to learn, and even beginners can operate.
5. Efficiency bottlenecks in roll changing and material receiving.
Downtime during roll changes remains a major loss; demand is high for automatic flying splice systems that require precise tension matching.
Polly's solution: 800mm Max unwind diameter. Larger than competitors' 500mm. oscillated rewinding make rewind roll tight and smaller .Fewer roll changes, higher productivity.
Key Conclusion:
High-speed seaming machines require perfect synergy between precision tension control and fully automatically operation. Film roll quality (end face straightness, edge tightness) is the foundation for stable operation. Polly Inte!ligent seaming machine solved above pain points one by one.
