Automatic BOPP Jumbo Adhesive Tape Roll Slitting Rewinding Machine - High Precision Continuous Production

‍

1. Product Overview

The Automatic BOPP Jumbo Adhesive Tape Roll Slitting Rewinding Machine is a high-efficiency, fully automated converting equipment tailored exclusively for the packaging and logistics industry. It serves as the core production equipment for mass manufacturing of transparent, colored, printed, and customized BOPP packaging tapes, which are widely used in cargo sealing, logistics packaging, industrial bundling, and daily commodity packaging worldwide.

The machine processes large-size jumbo BOPP film rolls coated with pressure-sensitive adhesive (acrylic glue or hot melt glue), and precisely slits and rewinds the raw jumbo rolls into standard industrial and civilian finished tape rolls with customizable width, diameter and length. It is compatible with all conventional BOPP adhesive tape production scenarios and is the mainstream high-demand equipment in the global packaging tape manufacturing industry.

2. Core Material Advantage: BOPP Adhesive Film

The excellent performance of finished BOPP packaging tape is derived from the superior physical and chemical properties of Biaxially Oriented Polypropylene (BOPP) film, which is the exclusive core material for high-quality packaging tapes:

High Transparency and Decorative Performance: The pure BOPP film has high light transmittance, making transparent tape clear and beautiful. It can also be dyed, printed and coated to produce colored tapes, printed logo tapes and anti-counterfeiting tapes to meet personalized market demands.

3. Why Jumbo Roll & Full Automation Are Indispensable

3.1 Jumbo Raw Roll Processing Design

The equipment supports super-large BOPP jumbo rolls with a width of 1.5-2.5m, a maximum diameter of 1000mm and a single roll weight of more than 1 ton. Traditional small-roll processing requires frequent material replacement, resulting in low production efficiency and unstable product consistency. The jumbo roll feeding design greatly reduces the frequency of material replacement, avoids material joints and defective products caused by repeated feeding, and effectively improves the yield and continuous production capacity. Meanwhile, manual handling of ton-level jumbo rolls has great safety hazards. The machine is matched with crane and forklift auxiliary feeding and automatic unwinding system, which completely eliminates manual handling risks and improves operational safety.

4. Core Technical Features & Advanced Components

4.1 Fully Automatic Unwinding & Zero-Speed Splicing System

Equipped with a motorized automatic unwinding stand with servo closed-loop back-tension control, which realizes constant-tension unwinding of large jumbo rolls to prevent film tension fluctuation, wrinkling and breakage. The core configuration is the zero-speed automatic splicing unit (butt splicer), which is the key to realize non-stop continuous production. When the raw jumbo roll is about to be exhausted, the system automatically senses the residual material amount, completes accurate butt joint between the tail of the old roll and the head of the new roll in zero-speed state, and automatically resumes high-speed operation. The whole splicing process does not interrupt the downstream slitting and rewinding process, eliminating shutdown waiting time and greatly improving comprehensive production efficiency by more than 30% compared with ordinary machines.

4.2 High-Precision Shear Cut Slitting System

Matching with servo automatic knife positioning system, operators only need to input the target tape width on the HMI touch screen. The servo motor automatically calibrates and positions the upper and lower slitting rings with high precision, eliminating manual measurement and debugging links. The quick order changeover function shortens the specification switching time from tens of minutes to several minutes, realizing efficient production of multiple specifications.

4.3 Multi-Zone Closed-Loop Tension & Web Guidance System

4.4 Dual-Drum Center-Surface Combined Rewinding System

4.5 Automatic Log Ejection & Circular Saw Cutting System

5. Complete Working Workflow

Step 1: Auxiliary Loading Use a crane or forklift to stably install the BOPP adhesive jumbo roll on the automatic unwinding stand, and install standard paper cores on the idle duplex rewinding shaft to complete pre-production preparation.

Step 2: Intelligent Setup & Threading Complete film threading through semi-automatic or fully automatic threading system. Operators input finished product width, rewinding diameter, production speed and other parameters via HMI touch screen, and the system automatically completes knife position calibration and tension parameter matching.

Step 3: High-Speed Continuous Production The machine starts intelligently and runs stably at a speed of 300-600m/min. During operation, the real-time monitoring system detects the residual material of the jumbo roll. When the material is insufficient, the automatic splicing unit completes zero-speed splicing without shutdown, and the production continues uninterrupted until the rewinding roll reaches the preset specification.

7. Frequently Asked Questions (FAQs)

This machine is specially designed for BOPP adhesive tapes, including transparent packing tapes, colored BOPP tapes, printed logo tapes, high-viscosity acrylic glue tapes, hot-melt adhesive tapes and other conventional and customized BOPP packaging tapes. It does not support non-adhesive film and special industrial tape production.

Razor slitting will produce fine burrs and "angel hair" on the tape edge. The fine debris will adhere to the adhesive layer, causing poor adhesion, tape edge warping and unbeautiful appearance. Shear cut slitting forms a flat, smooth and burr-free cutting edge, which ensures the cleanliness and adhesion performance of the tape, meeting high-standard commercial packaging requirements.

Yes. Equipped with a zero-speed automatic splicing unit and duplex dual-position rewinding system, the machine can complete jumbo roll switching and film transfer without shutdown. It realizes 24-hour long-term continuous production under normal operation conditions, greatly improving production efficiency and reducing idle time.

The servo automatic positioning system ensures the slitting accuracy reaches ±0.1mm, with no size deviation of finished products. The multi-zone tension control and web guide system avoid film wrinkling, breaking and deviation. The overall product yield is above 99.5%, which is far higher than semi-automatic equipment.

The equipment adopts full intelligent PLC + HMI one-click operation, with simple and intuitive operation logic. After simple training, one worker can supervise multiple machines at the same time, only responsible for material replacement and finished product collection, which greatly saves labor costs.

Fully customizable. Operators can set any width within the 12-1600mm range and any rolling diameter within the standard range via the touch screen. The machine supports flexible switching of multiple specifications in one day, adapting to small-batch customized orders and large-batch standardized production.

The stable running speed is 300-600m/min. According to different tape widths and rolling diameters, the daily output of a single machine can reach 8000-15000 standard tape rolls. The high-speed and continuous operation design ensures super-high production capacity.

The equipment has a stable structure and low maintenance cost. Daily maintenance only includes regular cleaning of the slitting knife group, lubrication of transmission parts, inspection of tension and web guide sensors, and regular replacement of wearing parts. The core components have a service life of more than 5 years with normal maintenance.

No. The dual-drum rewinding system has a natural heat dissipation function, which can timely dissipate the friction heat generated by high-speed winding. Meanwhile, the constant-tension winding avoids excessive extrusion of the adhesive layer, effectively preventing adhesive aging, degumming and tape deformation, and ensuring stable product quality.

Absolutely. This integrated equipment integrates unwinding, slitting, rewinding, cutting and discharging, with compact process and high automation. It does not need to be equipped with multiple auxiliary equipment, saves factory space and investment cost, and is the preferred equipment for new factories and large-scale tape production enterprises.
