Cast Machine Stretch Film

Yuhong cast machine stretch film is produced on cast extrusion lines as a single-layer or multi-layer co-extruded film. The cast process provides consistent optical clarity, puncture resistance, and controlled unwind tension for automated wrapping equipment. The film can be pre-stretched up to 300% and is designed to maintain holding force on pallets during transport and storage.

Differences from Blown Machine Film

Compared with blown film, cast machine wrap has a smoother surface, which reduces noise during automatic wrapping. The cling additive is controlled to provide consistent layer-to-layer adhesion, helping prevent load shifting and loose film tails on irregular or mixed-product pallets. Production monitoring of tackifiers and slip agents supports consistent elongation and break resistance on turntable, rotary arm, and orbital wrappers.

Technical Specifications

Manufacturing and Quality Control

Film gauge variation is controlled to below ±3%, which supports consistent break resistance on high-speed lines. The production team includes a polymer engineer with over 18 years of experience in cast film extrusion. Quality control covers incoming raw material inspection (IQC), in-process monitoring (IPQC), finished product inspection (FQC), and outgoing inspection (OQC). Each batch is tested for elongation, tensile strength, and cling force.

The production facility is ISO 9001:2015 certified. Materials are EU RoHS compliant, and performance testing has been completed by GALAB Laboratory, Germany. Third-party verification by SGS is performed regularly; test reports are available on request.

Typical Applications

Machine cast stretch film is used in a range of industrial and logistics settings:

• Logistics and warehousing: Stabilizing pallets in automated storage and retrieval systems.
• Beverage and bottling plants: Securing glass or PET bottle loads; film clarity supports label verification.
• E-commerce fulfillment: Wrapping mixed-SKU pallets with varying box dimensions.

Customization and Technical Support

Customization options include film thickness, width, color tinting, and recycled content integration where applicable. Technical support covers pre-sale specification matching and post-sale troubleshooting, including video-call assistance with the production team when required.

Frequently Asked Questions

What pre-stretch ratio is recommended for standard turntable wrappers?

For most applications, a pre-stretch ratio between 200% and 250% is appropriate. The ratio can be adjusted based on load weight and line speed; the technical team can provide guidance for specific equipment.

How does Yuhong maintain consistency between production batches?

Process parameters are monitored in real time during extrusion, and samples from each batch are tested for elongation, tensile strength, and cling force. Records are kept for traceability.

Can sample rolls be provided for machine testing?

Yes, sample rolls are available. Customers are encouraged to test the film on their own equipment and share machine data with the technical team for further specification adjustments if needed.

Is this film compatible with all types of automatic pallet wrappers?

The cast pallet machine film is designed for use on automatic wrappers that accept standard 3-inch cores, including turntable, rotary arm, and orbital machines. Compatibility also depends on roll width and diameter matching the equipment specifications. If the wrapper uses active pre-stretch, the carriage can be set to a lower ratio to avoid over-stretching.

What is the typical minimum order quantity for customized film?

For standard specifications, the typical minimum order is one 20-foot container. Custom thickness, width, or color requirements may have different minimums. Sample orders for evaluation can be discussed separately.

How should the film be stored to maintain performance?

Store the cast machine film roll in a cool, dry place away from direct sunlight and heat sources. Under recommended conditions, the film retains its properties for approximately 12–18 months from the shipment date.
