UV-Resistant Stretch Film

Xiamen Yuhong Plastic Products Co., Ltd. manufactures UV-Resistant Stretch Film at its 3,000 m² production facility in Xiamen, China. The company has produced packaging films since 2008 and operates under ISO 9001:2015 certification. This film is formulated with anti-UV additives that slow polymer degradation caused by ultraviolet radiation. It is intended for pallet loads stored outdoors or transported through environments with high solar exposure.

Technical Specifications

Full TDS report and batch test records are available upon request.

Application Environments

• Open-air storage yards for building materials, pipes, and metal profiles
• Outdoor warehouse staging areas with limited roof coverage
• Container loading at ports where cargo may sit in direct sunlight for days or weeks
• Construction sites where palletized materials are stored uncovered
• Export shipments passing through high-UV regions during transit

Film Selection Based on Exposure Conditions

Different exposure periods and load types require different film specifications. The following table provides a general reference. Actual recommendations should be confirmed through sample testing.

Performance Testing and Quality Control

Each production batch is tested for the following properties:

• Tensile strength and elongation at break according to ASTM D882
• Cling force and self-adhesion
• UV resistance using xenon arc aging per ISO 4892
• Performance retention after accelerated UV exposure
• Thickness consistency across the roll width

Third-party testing is conducted quarterly by independent laboratories. Test reports and certificates are available for customer audits.

Packaging and Storage Before Use

Finished rolls are individually wrapped in polyethylene bags to prevent dust and moisture ingress. Rolls are packed in export-grade cartons and palletized with strapping. Proper packaging protects the UV-Resistant Stretch Film during shipping and storage before first use.

Store unopened rolls in a cool, dry place away from direct sunlight and heat sources. Recommended storage temperature is between 5°C and 30°C. Under proper conditions, the film retains its original properties for 12 to 18 months.

Frequently Asked Questions

1. How long can this film be left outdoors?

Outdoor service life depends on UV intensity, temperature, film thickness, and wrapping layers. The weather-resistant pallet film is tested to withstand at least 1000 hours of xenon arc aging. In real outdoor conditions, this typically translates to several weeks to several months of exposure depending on location. For specific estimates, provide your location and storage period to Yuhong technical staff.

2. Does UV-resistant film still lose cling after sunlight exposure?

The anti-UV wrap is formulated to retain cling force better than standard stretch film after UV exposure. Performance retention is tested at over 90% after accelerated aging. However, all polyethylene films eventually degrade under prolonged sunlight. UV-resistant film slows this process but does not eliminate it.

3. Can this film be used on automatic wrapping machines?

Yes. The UV-Resistant Stretch Film is available in machine roll configurations with 3-inch cores and widths of 450 mm or 500 mm. Unwind stability and tension consistency are checked on wrapping simulators before shipment. Provide your machine model and current film specifications to confirm compatibility.

4. What thickness should I choose for outdoor storage?

For short-term exposure of 1 to 2 weeks, 17 to 20 μm may be sufficient. For medium-term exposure of 1 to 3 months, 20 to 25 μm is recommended. For long-term exposure or heavy loads, 25 to 30 μm provides additional margin. Test samples under your actual conditions before bulk ordering.

5. How should outdoor UV film be stored before use?

Store in a cool, dry warehouse away from direct sunlight and heat sources. Keep rolls in their original packaging until ready for use. Avoid stacking excessive pallets that may deform lower rolls.

6. Can I get samples for outdoor exposure testing?

Yes. Sample rolls are available for testing on your equipment and in your outdoor environment. The sample shipping cost can be deducted from the first formal order. Testing under actual UV conditions is the most reliable way to confirm suitability.

7. What documentation is available for supplier audits?

Yuhong can provide ISO 9001:2015 certificate, EU RoHS test report from SGS, SOI performance testing from GALAB Laboratory Germany, batch test records, TDS, and factory audit documentation. The in-house foreign trade subsidiary handles export compliance and shipment coordination.
