Cold Temperature Stretch Film

Cold Temperature Stretch Film is produced by Yuhong, a stretch film manufacturer in Xiamen, China. The product is also referred to as freezer grade stretch wrap or low temp resistant stretch wrap. It is formulated from a low-temperature resistant LLDPE blend that maintains flexibility and cling at temperatures down to -30°C.

Yuhong has manufactured low temperature pallet film for over 17 years. The production facility covers 3,000 m² and has an annual capacity of approximately 5,000 tons. The film is intended for cold storage and refrigerated transport applications where standard stretch film becomes brittle or loses adhesion.

Key Characteristics

• Low-temperature flexibility: The film remains elastic in freezing environments, supporting a pre-stretch ratio up to 250% inside walk-in freezers.
• Reliable cling at sub-zero temperatures: A specialized tackifier maintains layer adhesion in high humidity and cold conditions, reducing the risk of tail unwinding during transport.
• Smooth roll edges: Precision slitting minimizes edge micro-tears, which helps prevent film breakage on high-speed wrapping machines.
• Puncture resistance: The Cold Temperature Stretch Film withstands pressure from sharp ice buildup and frozen box corners, with a puncture resistance rating of at least 2.8 N.

Physical Performance Parameters

Material and Manufacturing Process

This low temperature pallet film is produced from virgin LLDPE resin using multilayer blown film extrusion. The inner layer provides cling, the middle layers provide tensile strength, and the outer layer is smooth to prevent pallets from sticking together when loaded side by side in refrigerated containers.

Low-temperature thermal stabilizers are added during the melt phase to reduce brittleness during prolonged cold exposure. The production process includes online thickness monitoring and precision slitting to maintain consistent roll quality.

Yuhong operates a 3,000 m² production facility with an annual capacity of approximately 5,000 tons. Quality control covers incoming materials, in-process production, finished products, and outgoing inspection.

Certifications and Compliance

• ISO 9001:2015 Quality Management System Certification
• EU RoHS Test Report issued by SGS
• SOI Performance Testing Certification from GALAB Laboratory, Germany
• Material safety and hazardous substance compliance documentation

Typical Application Scenarios

Seafood processing: In damp, icy environments, cold storage stretch film maintains adhesion and helps reduce pallet instability during winter transportation.

Ice cream and dairy cold rooms: The film supports high-speed automated wrapping lines, reducing the risk of line shutdowns caused by film breakage.

Frozen fruit logistics: Long-haul refrigerated transport involves constant vibration. The film's elastic recovery keeps boxes centered on the pallet, helping avoid product damage at destination.

Packaging and Shipping

• Individual rolls sealed in moisture-proof PE sleeves to protect edges from moisture during ocean transit.
• Export-grade corrugated cartons with foam plugs to lock roll cores in place.
• Bulk orders palletized and strapped with additional waterproof film.
• Loading photos provided before shipment for order traceability.

Frequently Asked Questions

1. Why is the wholesale MOQ set at 1 ton for custom orders?

Custom production requires machine setup, temperature profile adjustment, and raw material calibration. Small batches increase unit cost due to startup waste. For first-time buyers, sample rolls or existing stock may be available. Please contact our sales team for current options.

2. Can we test the film on our equipment before placing a bulk order?

Yes. Sample rolls can be shipped for evaluation. Provide your pallet size, average load weight, and wrapping machine model so we can recommend a suitable sample. Testing in actual freezer conditions is encouraged before a purchase decision.

3. Is the film compliant with EU and US import regulations?

Yes. The Cold Temperature Stretch Film is produced in an ISO 9001:2015 certified facility and carries EU RoHS test reports issued by SGS. No hazardous plasticizers or restricted polymers are used, supporting smooth customs clearance and environmental compliance.

4. What thickness should I choose for frozen pallet wrapping?

For light loads such as ice cream or bread, 20 μm is usually sufficient. For heavy frozen seafood cartons with sharp edges and ice buildup, 23 μm or 25 μm is recommended. The selection depends on load weight, pallet configuration, and wrapping equipment.

5. Does the film work with automatic wrapping machines?

Yes. For high-speed automatic turntable or rotary arm systems, machine jumbo rolls up to 15 kg or 20 kg gross weight are available. The film is engineered to handle pre-stretch ratios up to 300% without tearing.

6. Can you customize color, size, and packaging?

Yes. Roll width, color (clear, blue, black), and packaging can be customized to match specific machine lines or shipping requirements. Logo printing on film or export cartons is also available.
