Pre-Stretched Machine Stretch Film

Xiamen Yuhong Plastic manufactures Pre-Stretched Machine Stretch Film on in-house cast film extrusion lines. With more than 18 years of production experience in industrial packaging films, the company supplies this product to wholesalers, distributors, and industrial users in Europe, North America, and Southeast Asia.

Unlike standard machine film, this pre-stretched machine wrap is pre-stretched at the factory to an elongation of 200–250% before winding. Because the film is already close to its yield point when it reaches the user, the wrapping machine requires less tension to complete the wrap. Depending on equipment configuration and operating conditions, this may reduce energy consumption and mechanical load on automatic pallet wrappers.

Technical Specifications

Full TDS reports are available on request. Each production batch is tested for pre-stretch ratio consistency, residual elongation, tensile strength, and cling. Quarterly third-party testing by SGS verifies these values against BB/T 0024-2018.

Product Features

• Factory pre-stretched to 200–250%: The film is elongated near its yield point before winding, so wrappers require less tension to achieve a stable wrap.
• Lower energy demand: Internal testing on a standard 500 kg pallet showed approximately 30–40% lower energy consumption per pallet compared with standard 20 μm machine film under the same wrap pattern.
• Greater coverage per kilogram: In controlled tests, the film covered about 2.4 times more pallets per kilogram than standard 20 μm machine film at equivalent load containment.
• Reduced mechanical stress: Lower operating tension reduces load on rollers, belts, motors, and pre-stretch carriages, which may contribute to fewer maintenance interventions.
• Unchanged cling and clarity: Pre-stretching does not affect the film's one-side cling or optical transparency, so barcode scanning and visual inspection remain practical.
• Lightweight construction: Supplied thickness of 10–15 μm allows material savings without sacrificing containment for medium-weight loads.
• Customizable dimensions: Roll width (350–500 mm), core size (3-inch or 6-inch), and other specifications can be adjusted to match wrapping equipment.
• 12-month storage warranty: Film is warranted against manufacturing defects for 12 months from shipment, provided storage conditions are suitable.

Typical Applications

This pre-stretched reduced waste machine film is intended for automatic pallet wrapping of medium-weight loads. Common application areas include:

• FMCG (fast-moving consumer goods) distribution
• Home care and household chemical products
• Plastic products and light industrial goods
• General warehousing and logistics operations
• Export pallet wrapping for sea freight

The film works with automatic pallet wrappers that accept standard 3-inch cores. On machines with active pre-stretch carriages, operators should set the carriage to a low ratio or bypass mode to avoid over-stretching the film.

Quality Assurance and Certifications

ISO 9001:2015 – The factory is certified under this quality management system. Annual external audits confirm that pre-stretching and winding processes remain within defined tolerances.

EU RoHS – Compliance confirmed by SGS test reports. Certificates are shared within 24 hours on request.

SGS quarterly testing – Random samples are tested for pre-stretch ratio, residual elongation, tensile strength, and cling according to BB/T 0024-2018.

In-line monitoring – Stretch ratio is continuously recorded during production. Any deviation triggers an alert, and the affected section is quarantined before slitting.

Batch inspection – Every finished roll is checked for stretch-ratio consistency and unwind behaviour before dispatch.

Manufacturer Context

Xiamen Yuhong Plastic produces its stretch film range on in-house cast film extrusion lines at its Xiamen facility. Annual capacity is 5,000 metric tons. The company supplies hand stretch film, machine stretch film, and specialty stretch films to wholesalers, distributors, and industrial users in Europe, North America, and Southeast Asia.

Export operations are handled by a dedicated foreign trade subsidiary, while all film production takes place in the company's own facility.

Frequently Asked Questions

What does "factory pre-stretched" mean for my wrapping line?

It means the light machine wrap has already been elongated close to its yield point during manufacturing. On your wrapper, the film requires less tension to achieve the final wrap. This can reduce energy use, lower mechanical stress on machine components, and increase film coverage per kilogram.

Is Pre-Stretched Machine Stretch Film compatible with all pallet wrappers?

It is compatible with automatic pallet wrappers using standard 3-inch core holders, provided the film width and roll diameter match the machine's specifications. For wrappers with active pre-stretch carriages, we recommend setting the carriage to a low ratio or bypass mode to prevent over-stretching.

Does pre-stretching affect the film's cling or transparency?

No. The cling side remains fully functional, and the film retains sufficient clarity for barcode scanning and visual inspection. The mechanical pre-stretch does not alter the adhesive or optical properties.

Can I order custom widths or core sizes for this machine pre-stretched film?

Yes. Standard width customization ranges from 350 mm to 500 mm, with core options of 3-inch or 6-inch. Other specifications can be discussed on a case-by-case basis.

Do you provide samples for testing?

Yes. Sample rolls are available for evaluation. The customer covers the courier cost, which can be deducted from the first formal order. We recommend running the film on your own production line to verify compatibility and performance.

What warranty applies to this film?

The film carries a 12-month warranty from the shipment date, provided it is stored in a cool, dry environment away from direct sunlight and heat sources. If a manufacturing defect is confirmed through batch records or photographic evidence, replacement rolls are provided without requiring the customer to return the defective goods first.
