Custom Stretch Film Extrusion Machine for Advanced Biodegradable Films

The sustainable packaging shift demands high-performance alternatives to conventional plastics. However, processing biopolymers like PLA, PBAT, and starch-based resins on standard equipment causes severe thermal degradation, gauge variations, and poor load retention.

Our custom stretch film extrusion machine for advanced biodegradable films solves these technical bottlenecks. Engineered specifically for the unique rheological properties of eco-friendly resins, this production line ensures flawless melt stability, high output, and industrial-grade film performance.

Overcoming Biopolymer Processing Challenges

Biodegradable materials are highly sensitive to temperature, moisture, and shear stress. Standard extrusion lines break the molecular chains of these delicate materials, leading to brittle film and high scrap rates. Our custom engineering addresses these chemical vulnerabilities directly:

• Thermal Degradation Prevention: Advanced barrel zoning and precise cooling fans maintain temperatures within ±1℃. This strict tolerance prevents the rapid hydrolytic degradation common in PLA and PBAT.
• Low-Shear Hydrodynamic Melt: Proprietary low-shear screw configurations reduce frictional heat generation. By preserving the polymer's initial molecular weight, the machine maximizes the mechanical elongation properties of the final film.
• Starch Compound Homogenization: Custom melt-blending components ensure uniform dispersion of high-filler starch formulations. This eliminates micro-agglomerates that cause pinholes, tearing, and weak spots during downstream pallet wrapping.

Advanced Multilayer Co-Extrusion Systems

Optimizing the physical properties of compostable films requires strategic layer distribution. Our custom die blocks and feedblocks allow manufacturers to engineer precise multi-layer architectures:

2-Layer Stretch Film Machine

An efficient solution for standard compostable wrapping. It allows the separation of distinct functional resins, making it ideal for cost-effective, dual-material eco-friendly structures.

3-Layer Stretch Film Machine

The industry standard for premium biodegradable packaging. This configuration optimizes core film strength via the center layer while allowing distinct cling-and-slip additives on the outer skins to ensure perfect pallet adhesion.

5-Layer Stretch Film Machine

Engineered for ultra-thin, high-performance biodegradable films. It delivers maximum flexibility to integrate specialized barrier layers, control degradation rates, and significantly reduce expensive resin consumption without sacrificing puncture resistance.

Precision Engineering & Automation Control

Advanced Die Manifolds and Gauge Uniformity

Our high-precision automatic die systems utilize targeted feedback-pin assemblies. They instantly compensate for the narrow processing windows of bio-resins, delivering exceptional web uniformity. The resulting film features crystal-clear optical clarity, a prerequisite for barcode scanning in logistics.

Fully Automatic Stretch Film Machine

Designed for high-speed, continuous commercial manufacturing at line speeds exceeding 200 m/min.

• Closed-Loop Tension Control: Prevents roll deformation, telescoping, and wrinkling caused by the post-crystallization shrinkage of PBAT.
• In-Line Edge-Trim Recycling: Immediately re-feeds edge scrap back into the extrusion process, achieving zero-waste manufacturing.
• Non-Stop Winding: Automatic mandrel rotation and roll changeover maximize overall equipment effectiveness (OEE).

Semi-Automatic Stretch Film Machine

An adaptable system optimized for small batch production, custom formulation trials, and frequent job changeovers. It offers simplified maintenance layouts, lower initial capital investment, and absolute reliability for boutique or specialized product lines.

Premium Technical Performance

• Tensile Strength: Exceeds 35 MPa in machine direction (MD) and 30 MPa in transverse direction (TD).
• High Stretch Ratio: Achieves reliable pre-stretch levels up to 250%–300% on automated pallet wrappers.
• Global Standard Compliance: Produced film fully meets EN 13432, ASTM D6400, and AS 4736 industrial composting certifications.
