Bag On Roll Making Machine:A Complete Guide to Automated Bag-on-Roll Production
Introduction
Bag-on-roll products are widely used when individual bags need to be connected into a continuous roll.
For manufacturers, producing these bags efficiently requires accurate sealing, perforation, film feeding, winding and roll handling.
A Bag On Roll Making Machine therefore needs to do more than simply seal and cut film.
JIN CHANG provides several Bag On Roll Making Machine solutions, including JCH2(S), JCH1 and JCHR2(S).
From Film Roll to Finished Bag
One of the key concepts behind JIN CHANG's Bag On Roll machines is an integrated production flow.
The JCH2(S), for example, is designed to process the film from film roll to final bag through one production process. It incorporates computer control, servo motor technology and automatic film feeding.
This integrated approach can reduce the number of separate manual production steps.
For a manufacturer, fewer manual production stages can make production management easier.
Why Film Feeding Is Important
Film feeding directly affects the movement of the film through the machine.
If film tension or feeding becomes unstable, it can influence sealing, perforation and the final bag appearance.
The JCH2(S) uses automatic film feeding, while the servo motor makes bag-length and production-speed adjustments easier.
The machine also includes automatic stop functions for situations such as film running out, film feeding blockage, bag jams and color-scanning misses.
2-Line and 4-Line Production
The JCH2(S) can be configured for 2-line or 4-line production according to customer requirements.
This provides manufacturers with another factor to consider when planning production capacity.
For example, a factory should not simply ask:
"How fast can this machine run?"
It should ask:
"How many finished bags do we need to produce, what are the bag specifications, and how should production lines be arranged?"
This is a much more useful approach when selecting machinery.
JCHR2(S): More Flexible Bag-on-Roll Production
For manufacturers looking for additional automation and production flexibility, JIN CHANG's JCHR2(S) provides a different configuration.
The JCHR2(S) includes:
Twin servo motors
Twin photo cells
Synchronous sealing and perforation
Digital tension-less feeding-out roller
Fully automatic roll change
Independent A/B line counters
Two-line operation
The two production lines can produce different bag lengths, thicknesses and bag volumes independently.
This can be particularly useful when a factory needs to handle different orders without completely stopping the production system.
Automatic Roll Changing
Roll handling is another important part of bag-on-roll production.
If operators must frequently stop the machine to manually change finished rolls, production efficiency can be affected.
The JCHR2(S) incorporates a fully automatic roll-change system. The official product information also lists automatic core changing for the machine.
Automation at this stage can help reduce repetitive operator intervention.
Production Capacity
JIN CHANG lists a capacity of up to 600 bags per minute for bag lengths under 500 mm, with a line speed of up to 125 meters per minute, for the specified JCHR2(S) configuration.
However, buyers should avoid treating one maximum figure as the expected output for every product.
Actual production performance depends on the specific bag design, film and production conditions.
How to Select a Bag On Roll Machine
Before purchasing, manufacturers should clarify:
Film
Material
Thickness
Width
Bag
Length
Width
Type
Perforation requirements
Roll configuration
Production
Required output
Number of lines
Automatic roll change requirements
Factory
Available floor space
Operator requirements
Existing upstream equipment
Conclusion
A modern Bag On Roll Making Machine should be evaluated as a complete production system rather than simply as a cutting and sealing machine.
The important factors include:
Film Feeding + Sealing + Perforation + Winding + Roll Changing + Automation
JIN CHANG provides different Bag On Roll solutions so manufacturers can select a configuration according to their actual production requirements.
