Premium Coreless Stretch Film: Eco-Safe Packaging Solution

As the global supply chain demands more eco-friendly and efficient packaging solutions, coreless stretch film (aka film stretch coreless, film coreless, coreless film, stretch coreless) has rapidly emerged as a disruptive innovation for multiple industries. This in-depth report unpacks the evolution, technology, advantages, specifications, comparative analysis, and real-world applications of coreless stretch films, backed by reliable data and authoritative sources.

Industry Trends: The Ascendancy of Coreless Stretch Film

According to Freedonia Group's 2023 packaging report, the global stretch film market is projected to reach $4.1 billion by 2026, with coreless variants accounting for over 15% annual growth rate. Primary drivers include:

• Rising demand for sustainable/zero-waste packaging (eliminate cardboard or plastic cores).
• Logistics sector growth in Asia-Pacific and North America.
• Industrial automation and modern warehouse management requirements.
• Regulatory compliance for reduced packaging waste (per ISO 18601).

Defining Coreless Stretch Film

Coreless stretch film refers to shipping and packaging stretch wraps manufactured without any central core—eliminating both paper and plastic cores—resulting in weighed efficiency, easy recyclability, and reduced raw material costs. Its structure and performance are identical (or even superior) to conventional cored films while being more environmentally friendly.

• Material: Premium LLDPE (Linear Low Density Polyethylene), customizable to include bio-based, recycled, or anti-static formulations.
• Thickness: 10–35μm; Width: 250 to 900mm typical.
• Elongation: Up to 350%;
• Puncture resistance: ≥1.3 N/mm².
• Testing standards: ISO 527, ASTM D882, ROHS compliance.

Manufacturing Process: From Raw LLDPE to Finished Coreless Film

The advanced production of coreless stretch film leverages state-of-the-art extrusion and winding technology that is fully automated and meets strict international standards.

1. LLDPE Granule Preparation [ISO 1133, 1872]: Strict screening of raw material purity and melt index.
2. Extrusion [ISO 868]: Molten polymer is cast via a multi-layer slit die to create a uniform film.
3. Online Monitoring: Real-time thickness control (±3%) with optical and laser sensors, adhering to ASTM D8136.
4. Surface Treatment: Optional—antistatic, UV-blocking, or colored additives.
5. Coreless Winding: Specialized CNC-controlled winders begin the roll without a core, using a temporary biodegradable plug or a vacuum-start mechanism.
6. Automated Cutting & Edge-trim: Laser/ultrasonic finish for perfect roll edges.
7. QC Inspection & Palletization: Tensile/elongation, load retention, manual visual, and Toray puncture tests (ISO 527, ASTM D882).
