PLA PBS PBAT Starch Straw Sheet Extrusion Line Features
1. Multi-Material Compatibility & Eco-Friendly Design
Specifically compatible with PLA, PBS, PBAT, and starch-based materials. Both single-extrusion and co-extrusion are supported. For example, combinations like PLA + starch + PLA can be produced. The performance and cost are balanced, fully meeting global environmental protection requirements.
2. Energy-Saving & Consumption Reduction & Easy Maintenance
30%-40% more energy-efficient than similar equipment. High output without high energy consumption. The body is of an inclined-horizontal structure, simple to operate, and convenient for maintenance, helping to reduce operating costs.
3. Advanced Technology & Precise Control
Comes with vacuum exhaust and PID temperature control. The core components of the extruder, die head, and calendering machine have high compatibility, ensuring material purity, stable sheet quality, and uniform molding.
4. Intelligent Automation & Dual Model Selection
Equipped with PLC control and GWELL independent electrical system. The co-extrusion model also comes with a precise distributor; the single screw model has a crystallization drying function, and the twin screw exhaust model does not require pre-treatment in advance, meeting different production needs.
5. Flexible Customization & Food-Grade Safety
The thickness, width, matte/reflective surface of the drinking straw sheet can be customized. The produced sheet has high transparency, good thermal stability, and fully complies with strict food contact standards.

Product Features
1. Environmental-Friendly Raw Materials
The raw materials used are corn starch, as well as PLA/PBS/PBAT, these degradable biopolymer materials. As a professional extruder manufacturer, GWELL selects sustainable natural resources. The raw materials can be recycled, reducing dependence on non-renewable resources.
2. Fully Biodegradable
The raw materials are natural polymers. The processed straw boards can degrade in the natural environment and will not accumulate for a long time causing pollution.
3. Green Recycling without Residues
The used straw boards will be decomposed by natural microorganisms into plant nutrients, truly originating from nature and returning to nature. This fundamentally solves white pollution from the root cause.
4. Non-Toxic & in Line with Food-Grade Standards
The entire production process is sterile, and it undergoes strict disinfection and testing. The straw boards themselves are non-toxic and will not cause secondary pollution after degradation, fully meeting the safety requirements for food contact.
5. Low-Carbon and Environmentally Friendly Alternative
Straw boards can replace petroleum-based plastics and wood-based paper, reducing the consumption of fossil fuels and forest resources, achieving low-carbon production, and aligning with global ecological and environmental policies.
