[1] Independent 2023 tests per SGS show higher load retention for coreless stretch film due to tighter winding density.

3. Coreless Film Manufacturing Process (Visual Guide)

The production of coreless stretch film combines advanced resin formulation, extruder control, and high-precision winding technology. Below is a process diagram illustrating each stage, with certification criteria and technology checkpoints.

Process Flowchart: Coreless Stretch Film Manufacturing
Raw Material Selection ➔ Extrusion (Casting/Blown) ➔ Film Cooling ➔ Winding without Core ➔ Surface Gluing (if needed) ➔ Roll Slitting & Inspection ➔ Packaging (QC Checked)

Coreless Stretch Film: Waste-Free, Cost-Efficient Packaging

Key technical checkpoints:

Material Selection: LLDPE, mLLDPE, or PLA-based resins analyzed for melt index, toughness, tear resistance.
Extrusion: Casting (for optical clarity and high stretch) vs. Blown (for puncture resistance). Controlled via PLCs, meeting ISO 9001 ±2% gauge tolerances.
Winding: Coreless winders engineered for steady tension and roll stability, eliminating the need for paper/plastic supports.
Inspection: Each roll is X-ray thickness scanned and bar-tested to exceed ASTM D882 standards.

4. Key Technical Indicators — Chart Visualization

Performance curve: As thickness increases, both load force and elongation improve, but cost/roll grows at a sublinear rate. Liyabiobag's advanced process achieves superior force at lower gauges vs. competitors.

5. Why Choose Film Coreless? — Technological Advantages

Zero Core Hassle: No material wastage, no core disposal issues, boosting sustainability ratings.
Greater Film Yield: With no core, every meter is usable film, maximizing payload per delivery package.
Faster Automated Packing: Coreless rolls feed seamlessly into robotic and semi-auto stretch wrappers.
Precision Quality Control: Automated X-ray and laser scanning replace manual thickness sampling, hitting ISO/ASTM tolerances.
Bespoke Film Blends: Easily customize slip, UV resistance, opacity, or anti-static features by altering resin feed.
Regulatory Compliance: Liyabiobag coreless film meets ISO 9001:2015, FDA 21 CFR, REACH, and RoHS export standards.
Lower Shipping Costs: Reduce inbound non-film weight by 2–6%, slashing freight budgets and carbon footprint.

9. Technical FAQ / Professional FAQ

Q1: What is the main material composition of coreless stretch film?

Coreless stretch film typically uses 100% LLDPE (Linear Low-Density Polyethylene), optionally blended with mLLDPE or compostable PLA resins for higher flexibility and sustainability. The absence of a core means the roll is purely functional film, no extra support material.

Q2: What gauge/thickness range is commonly available?

Standard production spans 10–35μm, with 12μm, 17μm, 20μm, and 23μm as most sourced gauges. Thicker options (e.g., 30μm+) are preferred for robust industrial applications requiring boost in puncture and load strength.

Q3: What certifications should top-tier coreless films meet?

For export and regulated industries, ensure compliance with ISO 9001:2015, FDA (21 CFR 177.1520) for food contact, REACH (EU), and RoHS (electronics/medical).

Q4: How is load holding force determined?

Standardized under ASTM D4673, load holding force measures the film’s ability to secure palletized loads during shipping, factoring stretch ratio and tension stability. Premium blends like Liyabiobag deliver superior force at thinner gauges.

Q5: Are there specific installation guidelines for automated use?

Yes. Ensure wrapper compatibility (coreless feeder mechanism), set pre-stretch levels (e.g., 200–300%), and calibrate tension. Liyabiobag’s films are engineered for both manual and robotic coreless dispensers.

Q6: How is quality controlled during manufacturing?

Each production run is scanned using X-ray, laser, and manual bar measurements for thickness, elongation, and puncture standards (ISO/ASTM). Batches are QC-logged and traceable by barcode.

Q7: Can I order customized colors, slip agents, or UV-resistance?

Absolutely. Most producers (including Liyabiobag) offer bespoke colorants, slips, UV/anti-static coatings, and surface properties — with minimum order requirements varying from 500–1200 rolls.
