The Future of Safe Food Packaging: Chyi Yang WPE-Series PE Cling Film Blown Film Machine
The Global Shift to Non-Toxic Packaging
In the global food packaging sector, a major transition is underway. Retailers and consumers are moving away from traditional PVC cling films due to health concerns regarding plasticizers (DEHP) and environmental impact. The market is demanding a safer, non-toxic alternative: Polyethylene (PE) Cling Film.
To meet this demand, Chyi Yang Industrial Co., Ltd. presents the WPE-Series, a specialized blown film extrusion line engineered specifically to produce high-performance PE food wraps. This machine bridges the gap between safety and performance, delivering film that rivals PVC in clarity and stickiness without the toxic risks.
Core Technology: Mastering the "Cling" Effect
The biggest challenge in producing PE cling film is achieving the necessary tackiness (stickiness) while maintaining transparency. The WPE-Series solves this through advanced polymer engineering:
- Precision Liquid PIB Injection System Standard masterbatch additives are costly and often result in uneven distribution. The WPE-Series features a sophisticated Liquid PIB (Polyisobutylene) injection system.
- Cost Efficiency: Using liquid PIB is significantly cheaper than tackifier masterbatches.
- Uniformity: The system injects the liquid tackifier directly into the barrel, where specialized mixing screws ensure a homogeneous blend. This prevents "dry spots" and ensures consistent cling properties across the entire roll.
- Specialized Screw Design for Homogenization Processing LLDPE with liquid additives can cause slippage in standard screws. Chyi Yang utilizes a custom-designed screw geometry for the WPE-Series, incorporating optimized Shear Mixing Sections. This guarantees thorough plasticization and prevents material degradation, resulting in a film with superior mechanical strength and elongation.
Zero Waste Production: Inline Edge Trim Recycling
Cost control is the key to competitiveness. A standout feature of the WPE-Series is its ability to achieve 100% material utilization.
- Closed-Loop Recycling: The machine is equipped with an Inline Edge Trim Recycling System. As the film is slit into finished rolls, the edge trims are immediately captured, ground, and blown back into the extruder hopper automatically.
- No Material Loss: This process ensures Zero Waste. Every gram of raw material is converted into a sellable product. Manufacturers do not need to store, transport, or re-pelletize scrap, significantly reducing raw material costs and labor.
Automation & Efficiency: The WPE Advantage
Production speed and roll quality are critical for profitability. The WPE-Series is designed for non-stop operation:
- High-Clarity Cooling Technology: Equipped with a high-efficiency Dual-Lip Air Ring, the machine rapidly cools the melt to minimize crystal growth, ensuring high gloss and low haze.
- Fully Automatic Surface Winder: Our surface winder eliminates air entrapment, producing solid, flat-edged rolls.
- Inline Slitting & Roll Change: The machine can slit the film web into multiple finished rolls inline, with automatic cutting and roll changing capabilities.
Why Choose the Chyi Yang WPE-Series?
- Cost Savings: Liquid PIB injection + Zero waste inline recycling = Maximum ROI.
- Compliance: Produces 100% non-toxic, FDA-compliant food contact films.
- Sustainability: PE is fully recyclable, aligning with global circular economy goals.
