Cast Machine Stretch Wrap

Yuhong produces Cast Machine Stretch Wrap at its facility in Xiamen, China. The product is manufactured for automatic high-speed pallet wrapping equipment used in warehousing, logistics, food and beverage, and industrial packaging. The cast extrusion process produces film with consistent thickness and smooth unwind characteristics, which are important for continuous operation on automated lines.

The company has produced machine stretch film for 18 years. Production capacity is approximately 5,000 tons per year from a 3,000 m² facility. The high performance machine stretch film is supplied directly from our factory without intermediary trading companies.

Technical Specifications

Each production batch is tested for tensile strength, elongation, puncture resistance, cling force, and thickness variation. Test records are maintained for traceability.

Frequently Asked Questions

1. What is the difference between cast machine stretch wrap and blown machine film?

Automatic stretch wrap film is extruded through a flat die and cooled on a chilled roll. It generally has higher clarity, better gauge uniformity, and quieter unwind. Blown film is produced through a circular die and inflated with air. It typically has higher puncture resistance but lower clarity. Cast film is often preferred for high-speed automatic lines because of its consistent thickness and smooth unwind.

2. Can this film be used on any automatic wrapper brand?

The machine grade cast stretch film is supplied in standard widths and core sizes that fit most rotary arm, turntable, and orbital wrappers. To confirm compatibility, provide your machine model, current film width, core size, and pre-stretch settings. Yuhong technical staff can recommend the appropriate roll configuration.

3. Is food contact grade available?

Yes. Yuhong can supply food contact grade cast machine stretch film using virgin resin. Documentation is available for compliance with food packaging safety requirements. Specify food contact requirements when requesting a quotation.

4. What is the typical break rate for this film on automatic lines?

Under factory simulation tests, the break rate is controlled below 0.3% during 16-hour continuous operation. Actual break rate depends on machine condition, pre-stretch settings, load type, and film gauge. Testing on your own equipment is recommended before bulk orders.

5. How should cast machine stretch wrap be stored?

Store rolls in a cool, dry area away from direct sunlight and heat sources. Keep them in original packaging until use. Avoid temperatures above 30°C and high humidity. Properly stored film retains performance for 12 months.

6. Can I get a sample roll before placing a full order?

Yes. Sample rolls are available. Provide your pallet dimensions, average load weight, machine model, and current film specification. Yuhong will send a suitable sample for on-site testing. Sample shipping cost can be deducted from the first bulk order.
