Paper Bag & Large-Format Finishing Line
Continuous High-Speed Industrial Automation: Precision Cold Foil Decoration, Premium UV Special Effects Curing, and High-Capacity Automatic Stacking Delivery in a Synchronized Pass.
Solving Large-Format & Paper Bag Finishing Bottlenecks
Traditional multi-step standalone finishing setups cause registration drift, massive foil waste, substrate scratching, and excessive labor overhead.
Conventional Fragmented Production
- Severe Foil Wastage: Standard hot stamping and basic foil machines consume continuous foil over non-image areas, driving production costs up.
- Frequent Intermediate Pallet Handling: Manual handling between foil stamping, screen printing, UV curing, and stacking increases labor costs and leads to sheet edge damage or scuffing.
- Large Format Instability: Oversized shopping bag and luxury box blanks (>1000 mm) flex during transfer, resulting in curing inconsistencies and misaligned stacking.
- Thermal Distortion: Traditional hot stamping heat degrades thin shopping bag kraft paper (90-157 g/m²), producing curling and paper wrinkling.
Our Synchronized Integrated Finishing Line
- Intelligent Foil Economy: Equipped with Skip-Foil and Foil Pull-Back features to maximize foil utilization and slash raw consumable costs.
- Continuous In-Line Operation: Seamlessly transfers sheets from the Lite Cold Foil module directly into the UV/IR curing tunnel and automatic collector with zero manual touchpoints.
- Rigid High-Speed Sheet Control: Handles large formats up to 1500 × 1050 mm smoothly at up to 4,000 sheets/hour with flawless pneumatic registration.
- Cold Transfer Chemistry: Ambient temperature screen-printed cold foil adhesives eliminate heat curl on light paper while providing ultra-sharp foil edge resolution.
Integrated Line Architecture & Machinery Overview
Combining the QC-LTS Series Lite Cold Foil Unit with the ZP-106-UV-SZ Premium UV Curing & Automatic Stacking System for high-productivity finishing.
ZP-106-UV-SZ Premium UV Cure Machine
Equipped with high-output 35 kW UV curing and 2 kW automatic paper collection. Features a configurable 3 UV lamps with speeds reaching 4,000 sheets/hour.
QC-LTS Series Lite Cold Foil Machine with Collector
Connects inline with semi-automatic or fully automatic screen printing machines. Applies high-precision metallic foil onto UV adhesive patterns across wide formats with dynamic foil savings.
Synchronized 3-Station Finishing Workflow
A streamlined, uninterrupted mechanical sequence designed for high uptime, low waste, and maximum visual impact.
Screen Adhesive Printing & Cold Foiling
Connected inline with a screen printer, UV cold foil adhesive is applied to specified design zones. The QC-LTS pressure unit laminates cold foil onto the sheet with micron-accurate registration.
Premium UV & IR Radiative Curing
Sheets transition smoothly onto the heat-resistant conveyor belt into the 35 kW UV/IR drying tunnel. High-intensity photo-polymerization instantly cures the cold foil adhesive and clear topcoat varnishes.
Automated Non-Stop Sheet Collection
The fully integrated 2 kW paper collector uses pneumatic side-joggers and decelerators to stack cured sheets neatly at speeds up to 4,000 SPH, ready for immediate die-cutting and bag folding.
Sensory Embellishment & High-Value Visual Effects
Empower luxury packaging and paper shopping bags with premium finishes that boost brand appeal and command higher margins.
Ultra-Fine Line Cold Foil
Flawless reproduction of intricate typography, fine filigree lines, and micro-embossed patterns without thermal expansion distortion.
Large Solid Metallic Areas
Dense, mirror-like solid gold, silver, holographic, and tinted foil coverage across broad paper bag surfaces without pinholes.
Spot Gloss & Matte Contrast
Synchronized high-gloss UV varnish application directly over coated stocks or layered over cold foil for striking tactile depth.
Specialty Textures
Heavy deposit screen UV allows crystal abrasive, soft-touch velvet effects, and drip-off sensory finishes for boutique retail packaging.
Target Applications & Substrate Compatibility
Engineered for paper converters handling wide grammage spectra (90 to 450 g/m²) and expansive format sizes.
Luxury Retail Paper Bags
Ideal for fashion brand carriers, department store shopping bags, and cosmetic gift bags. Accommodates large sheets up to 1500 mm wide to fit one-piece folded bag designs with full foil side gussets.
Large-Format Folding Cartons
High-speed finishing for premium liquor gift sets, consumer electronics outer boxes, seasonal presentation cases, and confectionery packaging demanding high-opacity foil.
Display Packaging & Specialty Print
Point-of-sale (POS) standees, book jackets, promotional posters, and laminated corrugated micro-flute liners requiring precise spot varnish and cold foil stamping.
