Can a Side Sealing Bag Making Machine Produce Biodegradable Bags
2026-09-30
As global demand for sustainable packaging continues to rise, manufacturers increasingly ask whether a Side Sealing Bag Making Machine can process eco-friendly materials. The short answer is yes—but only when the machine is properly configured and the material is compatible. KINGPLAST, a leader in flexible packaging machinery, has spent years refining its Side Sealing Bag Making Machine technology to handle biodegradable films without sacrificing speed or seal integrity.
Understanding Biodegradable Films
Biodegradable bags are typically made from PLA (polylactic acid), PBAT, starch blends, or compostable co-polymers. These materials behave differently from traditional PE or PP films. They have lower melting points, higher sensitivity to heat, and different tensile strength. A standard Side Sealing Bag Making Machine may struggle with them unless key parameters are adjusted.
Key Machine Adjustments for Biodegradable Film
To run biodegradable film successfully on a Side Sealing Bag Making Machine, the following adaptations are essential:
| Parameter | Standard PE/PP Setting | Biodegradable Film Setting |
|---|---|---|
| Sealing temperature | 140–160°C | 100–130°C |
| Sealing pressure | Medium-high | Low-medium |
| Dwell time | Short | Slightly longer |
| Tension control | Standard | Precise, low tension |
| Cooling system | Optional | Recommended |
KINGPLAST engineers incorporate servo-driven sealing bars, independent temperature zones, and advanced tension control into every Side Sealing Bag Making Machine to ensure smooth processing of compostable materials.
Material Compatibility Checklist
Not all biodegradable films perform equally. Use this checklist before production:
-
PLA-based films – Excellent sealability at low temperatures.
-
PBAT blends – Good flexibility; requires moderate tension.
-
Starch-based films – Moisture-sensitive; pre-drying recommended.
-
Compostable laminates – Verify coating compatibility with seal layer.
KINGPLAST provides on-site material testing and custom recipe presets for its Side Sealing Bag Making Machine series, reducing trial-and-error downtime.
Performance Comparison: Traditional vs. Biodegradable
| Factor | Traditional PE Bag | Biodegradable Bag |
|---|---|---|
| Seal strength | High | Moderate to high |
| Production speed | 200–300 pcs/min | 150–250 pcs/min |
| Heat sensitivity | Low | High |
| Machine wear | Normal | Requires gentle handling |
| Environmental impact | High | Low |
With a KINGPLAST Side Sealing Bag Making Machine, speed loss is minimal—often under 15%—while maintaining bag integrity and print quality.
Side Sealing Bag Making Machine FAQ
Q: Can any Side Sealing Bag Making Machine run biodegradable film without modification?
A: No. Biodegradable films require lower sealing temperatures, reduced tension, and often upgraded cooling. A machine without these controls may produce weak seals or film distortion. KINGPLAST offers retrofit kits and factory-configured units specifically for eco-friendly materials.
Q: What is the maximum thickness of biodegradable film a Side Sealing Bag Making Machine can handle?
A: Most KINGPLAST Side Sealing Bag Making Machine models handle biodegradable film from 20 to 80 microns. Thicker compostable laminates may require a high-torque unwinder and reinforced sealing bars, which are available as options.
Q: Does running biodegradable film void the warranty on a Side Sealing Bag Making Machine?
A: Not if the machine is properly configured. KINGPLAST encourages biodegradable production and provides written guidelines. Following our recommended settings keeps your warranty valid while ensuring optimal performance.
Q: How do I clean a Side Sealing Bag Making Machine after running biodegradable film?
A: Residue from starch-based films can accumulate on sealing bars. Clean with a soft cloth and approved solvent after each shift. KINGPLAST includes a maintenance schedule with every machine.
Q: Is a Side Sealing Bag Making Machine from KINGPLAST suitable for compostable stand-up pouches?
A: Yes, with the correct sealing profile and cooling tunnel. Our Side Sealing Bag Making Machine series supports pouch-making modules for compostable applications.
