Product Overview

This fully automatic shrink packaging production line integrates three core functions – feeder, shrink pack, and stacking – into one streamlined system. It realizes unmanned and continuous operation from automatic feeding, film wrapping & heat shrink sealing to finished product stacking. Featuring high efficiency, stable performance and a labor-saving design, the line greatly improves packaging speed and consistency, reduces manual intervention and production cost, and ensures a neat, firm and standard package appearance for your goods.

Designed for manufacturers who demand reliability and throughput, this all-in-one solution eliminates the bottlenecks of semi-automatic or manual packaging processes. Whether you are packaging food cartons, beverage multipacks, pharmaceutical boxes, electronic components, or household items, this line delivers a flawless, professional finish every cycle.

Core Integrated Functions

Automatic Feeder System

The intelligent feeder accepts products directly from your upstream production line (conveyor, sorter, etc.). It automatically aligns, spaces, and feeds products into the wrapping section at the optimal speed. With photoelectric sensors and adjustable guide rails, the feeder ensures stable, jamfree product transfer – even for mixed or irregularly shaped items. No manual placement is needed.

High-Speed Shrink Wrapping Unit

The shrink pack module uses advanced film wrapping and heat sealing technology. Key features include:

Servo-driven film feeding for accurate film length and minimal waste.

Sealing system with constant temperature control, producing strong, straight, and smooth seal lines.

Tunnel-style heat shrink chamber with dual-zone independent temperature control and high-efficiency hot air circulation. The result: uniformly shrunk film that tightly conforms to product contours – no wrinkles, no burn spots, no loose corners.

Automatic Stacking System

After shrink wrapping, finished products enter the stacking unit. The stacking module counts, arranges, and stacks the sealed packs according to preset patterns (straight stack, interlocking, or layered stacking). The system can handle stack heights up to 1000mm, and the finished stacks are neat, stable, and ready for palletizing or direct warehousing. Optional robotic or pusher-type stackers are available.

Key Advantages & Added Features

True Unmanned Operation

Thanks to full integration and intelligent control, the line requires zero manual attendance during normal operation. One operator can monitor multiple lines from a central HMI. The system automatically compensates for film roll changes (with optional auto-splicing), adjusts to product speed fluctuations, and stops only when raw materials run out – ideal for lights-out manufacturing and night shifts.

Dramatic Labor Savings

A typical manual or semiautomatic packaging line requires 3–4 operators per shift. This fully automatic line replaces them completely, saving up to 10–12 labor positions daily (3 shifts). With rising labor costs and shortage of workers, the return on investment (ROI) is often achieved in less than 8 months.

High Packaging Speed & Consistent Quality

The line operates at 15–35 packs per minute (depending on product size), with ±1% repeat accuracy in seal position and stack count. Every pack looks identical – tight, crisp, and presentable – which enhances brand image and reduces customer complaints due to loose or torn packaging.
