Film Structure & Material

Resin Formulation:

C8 Octene and Metallocene LLDPE resins provide high tensile energy absorption, tear propagation resistance, and elastic recovery.

Controlled Cling Layer:

Polyisobutylene (PIB) or metallocene cling additives applied exclusively to the internal surface (one-sided cling) to eliminate pallet-to-pallet dragging in transit.

Micro-Layer Core Architecture:

Alternating structural sub-layers distribute stress concentrations to arrest tear propagation when punctured.

Cast vs. Blown Extrusion Technology

Cast Stretch Film:

Produced via high-speed chill-roll technology. Delivers optical clarity for barcode scanning, low unwinding noise (under 65 dB), uniform gauge tolerance (within ±3%), and consistent inner cling.

Blown Stretch Film:

Produced via vertical tubular air-cooled extrusion. Provides high puncture resistance, bi-directional tear strength, and high holding force for sharp, heavy, or irregular C-class cargo loads.

Performance Metrics

01.

Stretch Ratio vs Load Containment Profiles

Standard Machine Film (17µm – 20µm): Operates at 200% to 250% pre-stretch ratios. Ideal for uniform boxed pallet loads up to 900 kg.

Premium Metallocene Nano-Film (12µm – 15µm): Operates at 280% to 330% pre-stretch ratios. Delivers equivalent load containment while reducing plastic mass by up to 30% per pallet.

Heavy-Duty Blown Film (23µm – 35µm): Engineered for puncture resistance over extreme stretchability. Secures sharp-edged steel coils, brick pallets, and irregular industrial machinery.

02.

Environmental & Optical Integrity

Barcode Readability: High optical clarity allows handheld laser barcode scanners to read multi-layer wrapped pallets without unwrapping.

UV Resistance Options: Integrated UV-stabilizer additives preserve film tensile strength for up to 12 months in outdoor yard storage.

Hand vs Machine Application

Automatic Machine Application

High-Speed Pre-Stretch Units: Formulated to withstand rapid acceleration on rotary arm wrappers (up to 40 RPM) without edge splitting.

Roll Winding Precision: Straight-edge oscillation control keeps roll telescoping under ±1.0 mm, preventing sensor faults on automated lines.

Core Integrity: Reinforced 76 mm (3 inch) paper cores withstand high mechanical brake torque without crushing or inner wall deformation.

Manual Hand Application

Extended Core & Grip Inserts: Supplied with extended paper cores or reusable drop-in plastic end-cap handles.

Pre-Stretched Hand Film: Pre-expanded to 8–10 µm at the factory to lower operator physical effort while eliminating width neck-down during manual application.

Hemmed/Folded Edges: Folded outer edges prevent edge tears if rolls are dropped onto concrete warehouse floors.

Customization Capabilities

Color Tinting:

Opaque black, blue, white, or custom translucent tints for cargo theft protection, light shielding, and inventory identification.

Anti-Static Formulation:

Surface resistivity modified to 10^9 to 10^11 ohms/sq for ESD-sensitive electronics manufacturing and cleanroom storage.

VCI Corrosion Inhibitor:

Volatile Corrosion Inhibitor infused film for wrapping raw steel, automotive parts, and precision machinery.

Custom Printing:

1 to 2 color continuous inline flexographic printing for brand logos, handling instructions, or security warning graphics.

Manufacturing & Quality Control

Automatic Gauge Control (AGC):

Closed-loop Beta-ray continuous thickness sensors automatically adjust extrusion die bolts to maintain film thickness within ±3% tolerance across the web.

100% Inline Vision System:

Optical high-speed cameras scan the web to detect gels, pinholes, and edge micro-nicks during slitting and rewinding.

Laboratory Lot Testing:

Sample pulls from each master roll are tested for tensile strength (ASTM D882), cling force (ASTM D5458), and puncture resistance (ASTM F1306).

Full-Speed Application Testing:

Random finished rolls undergo full-speed run testing on Lantech test wrappers to verify pre-stretch ratios before batch release.

Packaging & Export Logistics

Roll Edge Protection:

Machine rolls feature plastic end-caps or protective PE sleeving to protect edges against side impacts.

Carton & Bulk Palletizing:

Hand wrap is packed into 4-roll or 6-roll heavy-duty corrugated cartons. Machine wrap is vertical-stacked on pallets with slip-sheets to maximize container volume.

Export Shipping Standard:

Pallets are strapped, corner-boarded, and stretch-wrapped onto ISPM 15 heat-treated wooden or plastic pallets. A standard 40ft HQ container holds 20 to 24 heavy-duty pallets.

Verified Net Weight Documentation:

Every pallet shipment includes certified tare, gross, and net plastic mass documentation to verify exact film weight.

FAQ

Q: How does switching from standard cast film to high-performance pre-stretched film affect overall packaging costs?

A: Pre-stretched film is pre-expanded during manufacturing near its yield point (typically 100% to 150% orientation) and rewound under controlled tension. When applied manually or on standard turntables, it requires minimal physical pull effort, eliminates film neck-down (width shrinkage), and reduces plastic resin consumption by weight by 30% to 45% per wrapped pallet.

Q: What causes film breakage on high-speed automatic stretch wrapping machines, and how do you prevent it?

A: Film breakage during high-speed wrapping stems from three main causes: resin gel inclusions, micro-nicks on roll edges created during slitting, or uneven gauge distribution causing localized stress concentration. We prevent this by running 100% of webs through optical gel-detection vision systems, using razor-sharp shear slitting blades, and maintaining a ±3% gauge tolerance across the web.

Q: What is the difference between C6 (Hexene) and C8 (Octene/Metallocene) resin formulations in stretch film performance?

A: C6 LLDPE resins provide baseline tensile strength suitable for light-to-medium hand wrap applications. C8 Octene and Metallocene resins feature longer polymer chain branching, which increases puncture energy absorption and tear propagation resistance. This allows thinner gauge films (e.g., 12µm to 15µm) to deliver equal or superior load containment compared to thicker 20µm C6 films without snapping under high pre-stretch ratios.

Q: How do you prevent machine stretch film rolls from telescoping during transport and storage?

A: Roll telescoping (sliding inner layers outward) occurs when rewinding tension is improperly balanced or when paper cores absorb ambient moisture and lose dimensional stability. We use closed-loop automatic winding tension control systems that adjust winding torque as roll diameter increases. Additionally, we use high-crush-strength paper cores sealed inside moisture-barrier plastic wrap.

Q: What unwinding noise level should we expect between cast and blown stretch films on automated packing lines?

A: Cast stretch film produces a smooth, quiet unwind off the roll (typically under 65 dB), making it ideal for indoor warehouse environments with strict noise exposure limits. Blown stretch film produces a loud, high-tack unwinding sound (often exceeding 85 dB) due to its inherent resin tackifiers and mechanical surface structure, but provides higher puncture resistance for heavy industrial loads.

Q: How do you verify net film weight and length per roll to guarantee we receive exact ordered quantities?

A: Every roll passes over calibrated inline digital scales after rewinding. Net plastic weight is calculated by subtracting the certified weight of the paper core and packaging materials. Batch inspection certificates provide net weight, total linear meterage, measured thickness, and roll count per pallet for complete supply chain transparency.
