Keqi L-shaped tape application platform adopts exclusive L-turn conveying layout tailor-made for special packaging products like paper bags and envelopes, delivering unique space-saving, cost-saving and customized advantages compared with linear, B/C/U-type straight machines. Its core L-shaped folded conveyor structure greatly shortens the overall machine length, making it ideal for printing factories with narrow production workshop passages or limited linear space beside folder gluers. Different from other flat straight-line taping equipment, the L-turn design perfectly matches the conveying logic of long paper bags, slim envelopes and narrow corrugated cartons, avoiding material jamming, skew feeding and double-sheet stacking that often occur on ordinary linear machines.

The platform supports an optional rotary hot melt scraping glue system as a core upgrade function. This innovative scraping structure replaces expensive full rolls of double-sided tape by pre-coating hot melt glue on release liner, then transferring glue to packaging surfaces automatically, which drastically cuts long-term adhesive material costs for mass production factories. It retains mature multi-roller correction modules shared with C/U series machines, locking taping positioning tolerance stably at ±2mm even for thin, soft paper bags and easily deformed luxury gift boxes, ensuring neat tape alignment without offset or missing tape.

Equipped with standard human-machine touch control system, the machine stores multiple groups of product parameters for one-click switching between different bag and box styles, slashing mold change and debugging time. Customers can flexibly configure 1–4 tape applicator heads, and add customized modules including release paper scrapers, easy-tear tape heads and transparent sealing tape heads as needed. The whole machine adopts thickened steel frame and brand servo motors for stable continuous high-speed operation, and can be installed offline independently or inline connected with box making, envelope making and folder gluer lines without large-scale reconstruction of original production equipment. One L-type platform can replace 2–3 manual taping workers, effectively lowering factory labor expenditure, and all structural sizes, tape types and functional assemblies support full customization per customer’s special packaging demands.

Keqi L-shaped automatic taping platform is a special customized taping solution developed for hard-to-process long, slim and irregular packaging products, covering mainstream post-printing packaging sectors with targeted adaptability for special-shaped paper products that cannot run smoothly on standard straight-line taping machines. Its primary applicable products are various special paper bags and mailing envelopes, including thin retail shopping bags, food packaging paper bags, courier envelopes and sealed document envelopes; the L-turn conveying track guides long narrow paper materials to pass through feeding, correction and taping stations steadily without bending or wrinkling printed surfaces.

It widely serves e-commerce online shopping packaging production lines, processing mass express corrugated boxes, logistics shipping cartons and lightweight outer delivery packaging, applying easy-tear opening tape and sealing double-sided tape in high volume. For high-end market segments, the platform fits luxury gift packaging, tobacco and alcohol color printed cartons and craft decorative boxes, where precise, scratch-free taping is required to protect coated, matte-laminated printed patterns. The equipment adapts to all paper substrates under 2mm thickness, including lightweight corrugated board, art coated paper, soft grey board and thin kraft paper for bags.

This machine supports dual production modes: offline independent batch processing and inline linkage with folder gluers, die-cutting machines and envelope forming machines to finish taping in one continuous workflow. It is compatible with double-sided tape, easy-tear tape, transparent sealing tape and hot melt scraping glue systems, and all machine dimensions, conveyor width and tape applicator combinations can be fully customized to match unique packaging specifications. It fits small-batch custom packaging workshops focusing on special paper bag orders as well as large-scale mass production factories with high-volume e-commerce carton output, covering all taping procedures for long, narrow and special-shaped packaging that ordinary linear taping platforms cannot handle efficiently.
