- 1 machine, 1 process — Complete PE liner insertion and top hemming in a single automated operation
- Labor cost reduction — Replaces manual sewing jobs; frees factory floor space for other operations
- Lean manufacturing ready — Smaller factory footprint, fewer operators, fewer process steps
- Clean manufacturing — No human contact inside PE liner; suitable for hygienic packaging requirements
- Competitive pricing — Massive reduction in sewing thread usage improves cost per sack
What does Phyllis's conversion line automate in PP woven sack production?
The Phyllis conversion line automates the entire process of inserting a PE inner liner into a PP woven sack and hemming the top of the sack mouth — all in one machine and one continuous process. This replaces traditional manual sewing operations that require multiple workers and separate process steps.
How does the automated conversion line reduce labor costs?
By replacing manual sewing jobs on the sack mouth with automated hemming, the conversion line significantly reduces the number of operators needed per shift. Factory floor space previously occupied by sewing stations can be reclaimed, enabling a slimmer, leaner factory layout.
Is Phyllis's conversion line suitable for hygienic packaging requirements?
Yes. Because the machine handles PE liner insertion without any human hand contact inside the liner, the process supports cleaner manufacturing standards. This makes it well-suited for packaging food products, chemicals, fertilizers, and other contents that require contamination control.
Does Phyllis offer conversion lines for FIBC bulk bag production as well?
Yes. Phyllis offers dedicated conversion lines for both PP woven sack production (S0005) and FIBC / bulk bag production (S0028). Please refer to the FIBC Production Line section or contact our team for FIBC-specific specifications.
