Roll Bag Making Machine

The HOWIE Automatic Roll Bag Making Machine produces roll-type plastic bags—including garbage bags, refuse sacks, food packaging rolls, and heavy-duty industrial liners.

Feature

HOWIE Automatic Roll Bag Making Machine

High-Speed Solution for HDPE, LDPE & LLDPE Roll Bag Production

The HOWIE Automatic Roll Bag Making Machine produces roll-type plastic bags-including garbage bags, refuse sacks, food packaging rolls, and heavy-duty industrial liners.

It integrates automatic tension control, Siemens/Delta PLC control, Yaskawa servo positioning, heat sealing, dynamic cutting, and automatic roll winding for 24/7 industrial production.

Designed for HDPE, LDPE, LLDPE, bio-plastics (PLA/PBAT), and up to 100% recycled (PCR/PIR) films, HOWIE machines help packaging manufacturers increase throughput while cutting labor costs and raw material scrap.

Core Value Drivers

High-Speed Industrial Stability

Built with a heavy-duty reinforced frame and low-vibration transmission, the system handles continuous 24/7 operation with minimal downtime.It maintains precise bag dimensions and constant line speeds to help factories hit strict delivery deadlines.

Precise Servo & Tension Control

Driven by Yaskawa/Panasonic servo motors and a Sick/Keyence photocell tracking system, the machine delivers high length accuracy (±0.5 mm) on both plain and printed film.Operators can adjust job settings instantly via the multi-language touchscreen interface.

Structural Heat Sealing

Equipped with copper heating bars and digital temperature controllers, the machine delivers uniform, high-strength seals across film gauges from 0.007 mm to 0.06 mm.

Automatic Roll Winding & Changing

The integrated winder processes core or coreless rolls automatically.It changes rolls and counts finished units without stopping or slowing down production, reducing manual handling by up to 60%.

Material & Application Breakdown

Material	Key Characteristics	Target Products
HDPE	High tensile strength, lightweight, cost-effective	Produce bags, thin trash rolls, counter bags
LDPE	Flexible, high puncture resistance, smooth surface	Retail packaging rolls, draw-string trash bags
LLDPE	High tear resistance, high elongation	Heavy-duty waste liners, construction bags
Recycled Blends	Handles uneven melt flow index (MFI)	Eco-friendly industrial liners

Quality Control & Testing

Every unit undergoes a 3-Stage Testing Protocol before dispatch:

Mechanical Inspection

Frame rigidity, drive gear alignment, and torque checks.

Electrical Audit

Circuit insulation, safety emergency stops, and PLC logic verification.

48-Hour Film Trial

Continuous operational run using customer-specified raw material to test seal integrity, roll-changing accuracy, and speed stability.

Technical Support

On-Site Commissioning

Field engineers deployed globally for setup and staff training.

Remote Diagnostics

PLC network integration for instant online troubleshooting.

Global Spare Parts

Standardized OEM components for fast international delivery.

FAQ

Q: What bag types and materials can this machine process?

A: It produces garbage bags, produce rolls, star-seal bags, and industrial liner rolls. It supports HDPE, LDPE, LLDPE, bio-degradable films (PLA/PBAT), and up to 100% recycled (PCR/PIR) materials.

Q: Can the machine handle both core and coreless roll packaging?

A: Yes. The automatic roll winding system can be configured for coreless bag rolls or integrated with an automatic paper core feeding unit depending on your market requirement.

Q: How does the servo system prevent raw material waste?

A: The Yaskawa/Panasonic servo motor works with Sick photocell sensors to continuously lock film position within ±0.5 mm. This eliminates mis-cuts, mis-seals, and print-registration alignment drift during continuous runs.

Q: Can technical parameters be customized for our factory setup?

A: Yes. Bag width (up to 1200 mm), voltage (380V–480V), sealing knife structures, and inline punching units can be tailored to match your target products and local electrical grid.

Q: How are installation and operator training handled for international buyers?

A: We provide complete English technical manuals, step-by-step installation videos, and remote PLC diagnostics support. On-site dispatch of field engineers for commissioning and staff training is also available worldwide.
