9. FAQ & Services
Q1: What is the stretch performance of the film produced by this line?
The line supports multi-layer structure design, allowing different stretch properties based on material formulation. Standard stretch film elongation can reach 100%–400%, depending on the combination of LLDPE, mLLDPE, and tackifier ratios.
With proper layer distribution and process optimization, the line can produce:
- Standard hand stretch film
- High-performance machine film
- Pre-stretch film
Formula optimization testing can be supported before delivery.
Q2: What film widths are available?
Standard finished film width configurations include:
- 1000 mm
- 1500 mm
- 2000 mm
- 3000 mm
Maximum width can be customized up to 4500 mm.
The winding system supports multi-slit structures, allowing simultaneous production of different roll sizes for improved flexibility.
Q3: Do you provide formula and technical support?
Yes. In addition to equipment supply, we provide basic process guidance, including:
- Raw material formulation recommendations
- Machine parameter adjustment guidance
- Technical support during initial production
This helps shorten commissioning time and improve production stability.
Q4: How do you ensure machine performance before shipment?
All production lines undergo Factory Acceptance Testing (FAT) before delivery.
We support:
- 2–4 hours of continuous full-load operation testing
- Customer-provided material testing
- Real-time monitoring of output, line speed, and thickness tolerance
Customers may participate on-site or remotely before shipment approval.
Q5: Can we visit running production lines?
Factory visits are welcome.
With customer permission, we may also arrange visits to running projects to observe real production performance and automation levels.
