BAG CONVERSION & PRINTING

Engineering Overview

The KKP ENTERPRISE HDPE Laminated Paper Bag Machine is a specialized industrial converting line engineered for the manufacture of multi-layer composite sacks. Combining high-strength HDPE woven fabric with multi-wall bleached or brown Kraft paper, these composite bags provide extreme puncture resistance with complete moisture barrier protection. The machine automates continuous multi-web feeding, edge folding, hot-melt adhesive dispensing, bottom crepe paper tape hemming, and ultrasonic patch reinforcement. Capable of producing 30 to 45 bags per minute, it is the premier standard for packaging dry-mix cement, chemical resins, fine minerals, and food-grade milk powder.

Key Performance Highlights:

Bag Width Range: 350 mm to 650 mm

Bag Length Range: 500 mm to 1100 mm

Production Output: 30 to 45 finished composite sacks / minute

Material Compatibility: Multi-wall Kraft Paper (70-90 GSM) + HDPE Woven Fabric (60-90 GSM)

Sealing Technology: Hot-melt adhesive dispensing + Bottom crepe paper stitch/seal

Control System: Delta / Omron PLC with Color Touchscreen HMI

Machine Advantages

Built with Heavy-Duty Componentry

Engineered for continuous 24/7 industrial production with lowest maintenance intervals and high uptime reliability.

Multi-Web Synchronized Feeding

Handles multiple reels of Kraft paper and HDPE woven fabric simultaneously with load-cell tension control and automatic edge guide alignment.

Automated Hot-Melt Adhesive Dispenser

Applies precision glue beads along bag seams and bottom patches, creating a 100% sift-proof and moisture-tight seal.

Heavy-Duty Crepe Paper Tape Sewing Unit

Reinforces bag bottoms with high-strength crepe paper tape and multi-thread industrial chain stitching for 50 kg weight capacities.

Servo-Driven Multi-Blade Rotary Cutter

Provides clean, burr-free cuts across multi-layer composite materials without paper tearing or woven fabric fraying.

Touchscreen Parameter Management

Stores preset bag recipes, temperature settings, and batch targets for fast 15-minute changeovers between different sack sizes.

Automated Defect Rejection & Stacking

Monitors tape tension and seam integrity, automatically diverting incomplete bags before final conveyor batch stacking.
