The global corrugated packaging market continues to scale, heavily driven by the e-commerce sector. Industry data indicates that up to 30% of e-commerce purchases result in returns. This specific consumer behavior has created a massive demand for "resealable" and "easy-open" corrugated boxes.
To manufacture these e-commerce mailer boxes, packaging suppliers must apply two distinct materials to the corrugated cardboard: tear tape (for consumer opening) and double-sided tape (for original sealing and return sealing).
For packaging manufacturers, finding a fully automatic double-sided tape applicator machine capable of applying both tapes in a single pass is critical for maintaining production speed and reducing labor overhead.
The Production Bottleneck in Resealable Corrugated Packaging
Standard corrugated box designs require the tear tape and the double-sided tape to run parallel along the box flap. Because the flap area is limited, these two tapes must be positioned with minimal distance between them.
Traditional single-head tape applicators require running the corrugated board through the machine twice, or using two separate machines in a series. This method causes several issues:
Decreased Throughput: Two passes double the production time.
Alignment Errors: Feeding the board twice increases the risk of misalignment. If the tear tape overlaps the double-sided tape, the box functionality fails.
Material Waste: Misaligned tape placement on expensive corrugated substrates leads to higher scrap rates.
The Solution: Dual-Row Tape Application Technology
To resolve this, modern corrugated box tape application equipment utilizes a dual-row head design. This allows the application of both tapes simultaneously on corrugated boards, from E-flute to heavy-duty double-wall profiles.
1. Front and Back Row Configuration
Instead of mounting tape heads side-by-side—which limits how close the tapes can be applied due to the physical width of the applicator hardware—our machinery utilizes a staggered front and back row system.
The front row applies the double-sided tape.
The back row applies the tear tape.
2. Minimum Distance Tape Placement
Because the applicator heads operate on separate axes (front and back), operators can adjust the lateral position of the heads to place the two tapes extremely close together. This specific adjustment capability meets the strict die-line requirements of custom e-commerce corrugated boxes without hardware interference.
Siemens PLC Control: Stability for High-Speed Production
Applying pressure-sensitive tape to corrugated cardboard at high speeds requires precise tension control and cutting mechanisms. Machine vibration or inconsistent board feeding will cause tape breakage or placement drift.
Our fully automatic tape applicator machines are equipped with a Siemens PLC (Programmable Logic Controller) system. This industrial control system provides three core advantages for box manufacturers:
Mechanical Stability: The Siemens PLC synchronizes the corrugated board feeding speed with the tape unwinding speed, preventing tape stretching or snapping.
Precision Cutting: The system controls the servo motors to execute millimeter-precise tape cut-offs, eliminating tape overhang at the edges of the corrugated board.
Fast Setup and Changeover: Operators input box dimensions and tape lengths directly into the Siemens touch screen. The system calculates the application timing automatically, reducing the mechanical debugging process from hours to minutes when switching between different box sizes.
Production Data and ROI for Box Manufacturers
Integrating a dual-head tear tape and double-sided tape applicator provides measurable returns for packaging facilities:
Production Speed: Applying both tapes in a single pass increases throughput by up to 100% compared to dual-pass methods.
Yield Rate: The Siemens PLC synchronization and staggered head design maintain a ±1 mm placement accuracy, reducing corrugated board waste.
Market Expansion: Facilities equipped with single-pass dual-tape technology can efficiently bid on high-volume fulfillment contracts for major e-commerce brands requiring "frustration-free" and return-ready packaging.
Conclusion
The shift toward resealable e-commerce boxes requires packaging manufacturers to upgrade their finishing equipment. By utilizing a fully automatic double-sided tape applicator machine with staggered dual-row heads and Siemens PLC controls, corrugated box suppliers can meet complex design requirements, increase hourly output, and secure high-volume e-commerce contracts.
