Cast Machine Stretch Wrap for High-Speed Pallet Wrapping Lines

Yuhong has produced cling stretch film since 2008 at its factory in Fujian, China. The company operates its own extrusion lines and supplies film to factories, food processing plants, and household distributors in more than 30 countries. Because production is handled in-house, there is no trading company intermediary between the factory and the buyer.

Product Lines

Industrial Protective Cling Film

This film is produced for temporary protection of metal parts, machined components, and equipment surfaces during storage and shipping. The film clings to smooth surfaces without adhesive and can be removed without leaving residue under normal conditions. Anti-rust and UV-resistant formulations are available for extended outdoor or humid storage.

Common specifications:

• Thickness: 20 μm to 50 μm
• Width: 100 mm to 1000 mm
• Core size: 2 inch, 3 inch, or custom
• Adhesion level: adjustable for different surface types

Food Grade Cling Film

Food grade cling film is produced from virgin polyethylene resin and complies with food contact material requirements. It is used for wrapping fresh meat, cheese, prepared meals, and produce. Anti-fog options reduce condensation on the film surface, which helps maintain product visibility in refrigerated display cases.

Common specifications:

• Thickness: 10 μm to 20 μm
• Width: 300 mm to 600 mm
• Core size: 2 inch or 3 inch
• Packaging: roll with cutter box or bulk roll

Household Cling Wrap

Household cling wrap is supplied in cutter boxes for retail and consumer use. Roll lengths and box designs can be customized for private label distribution. The film is produced from the same extrusion lines used for food grade film, with thickness and cling adjusted for everyday kitchen handling.

Common specifications:

• Thickness: 8 μm to 15 μm
• Width: 300 mm or 450 mm
• Roll length: 10 m to 100 m
• Packaging: printed cutter box, shrink-wrapped

Resin Formulation and Customization

The resin blend can be adjusted for specific requirements. Parameters that can be modified include:

• Cling level, from low-tack for easy removal to high-tack for secure holding
• Thickness and width within the ranges listed above
• Anti-rust additive for ferrous metal protection
• UV stabilizer for outdoor storage
• Anti-fog agent for refrigerated food display
• Color, including clear, blue, black, or custom
• Core size and roll length

Small trial batches are accepted for new formulations. Customers are encouraged to test samples on their actual products before placing bulk orders.

Sample and Testing Support

• A4 size film sheets are available free of charge for initial evaluation.
• Short rolls are available free of charge for on-machine or on-product testing.
• Full production roll samples are available for a small fee, which can be deducted from the first bulk order.
• Sample requests should include the substrate material, storage conditions, and expected removal timeline so the correct formulation can be selected.

For quality issues confirmed to originate from manufacturing defects, replacement or compensation is provided according to the agreed warranty terms.

Frequently Asked Questions

1. Will the film leave residue when removed?

Residue depends on the surface material, storage duration, and temperature. Smooth surfaces such as glass and polished metal generally release cleanly. Porous or painted surfaces may retain trace amounts if the film is left in place for extended periods or exposed to high heat. Testing on your actual product is recommended before bulk use.

2. What thickness should I choose?

For short-term handling and basic dust protection, 20 μm to 30 μm is usually sufficient. For longer storage or rough shipping conditions, 35 μm to 50 μm provides better puncture and tear resistance. The application guide above lists typical ranges for each product line. Contact the sales team with your specific scenario for a recommendation.

3. Can adhesion level be customized?

Yes. The resin formulation can be adjusted to match the substrate and the intended removal method. Provide the surface material, texture, and removal timeline so the appropriate tack level can be selected.

4. Can I get samples before placing a bulk order?

Yes. Free A4 sheets and short rolls are available for testing. Full roll samples can be supplied for a small fee. Sample costs can be deducted from the first formal order.

5. How are orders documented and shipped?

Export documents including CO and FORM E are prepared based on the destination country. All shipments use heat-treated pallets that meet ISPM 15 rules. Loading photos are provided before shipment for order confirmation.

6. What is the minimum order quantity?

For standard specifications, the MOQ is typically one pallet. Custom formulations or private label packaging may require a higher MOQ depending on the material and printing setup. Contact the sales team for specific requirements.

7. How should cling film be stored?

Store in a cool, dry place away from direct sunlight and heat sources. Keep rolls in original packaging until use. Under proper conditions, film performance remains stable for 12 months.
