Puncture-Resistant Stretch Film

Puncture-Resistant Stretch Film from Yuhong is a cast-extruded stretch film designed for wrapping palletized goods with sharp edges, protruding fasteners, or irregular shapes. The film is formulated to resist tear propagation after localized punctures, helping maintain load stability during handling and transport. It is available in hand-grade and machine-grade rolls to suit different wrapping methods.

Xiamen Yuhong Plastic Products Co., Ltd. has produced packaging films since 2008. The company operates a 3,000 m² production facility with more than 50 employees and an annual production capacity of approximately 5,000 tons. Products are supplied to customers in China, Southeast Asia, Europe, and North America.

What Makes Puncture-proof Stretch Wrap Different?

Standard stretch film may tear quickly once a small puncture occurs, especially when the film is under tension. Puncture-proof stretch wrap uses a modified LLDPE blend and controlled extrusion conditions to improve tear propagation resistance in both machine direction (MD) and transverse direction (TD). This means a small hole or nick is less likely to spread across the full roll width, reducing the risk of complete wrap failure.

Key Product Features

• Improved tear propagation resistance: A localized puncture or cut is less likely to expand into a full-width tear under wrapping tension.
• Suitable for sharp or irregular loads: Designed for pallets containing metal parts, ceramic tiles, wooden crates, or other products with edges that can damage standard film.
• Consistent stretch performance: Maintains reliable elongation and recovery during hand or machine wrapping, supporting stable load containment.
• Cling on both sides: Provides secure layer-to-layer adhesion without leaving residue on packaged goods.
• Available in hand and machine grades: Hand rolls for manual application; machine rolls for automatic turntable, rotary arm, or orbital wrappers.

Selection Guide

The following table provides general recommendations for choosing between standard stretch film and puncture-resistant stretch film based on load characteristics.

Testing and Quality Control

Yuhong follows a four-stage quality control process: incoming material inspection (IQC), in-process quality control (IPQC), finished product inspection (FQC), and outgoing quality control (OQC). Key properties such as tensile strength, elongation, tear resistance, and cling force are tested for each production batch.

The production facility is ISO 9001:2015 certified. Products are supported by EU RoHS test reports from SGS and performance testing documentation from GALAB Laboratory, Germany. Third-party test reports and technical data sheets are available upon request.

Applications

Puncture-resistant hand film is commonly used in the following scenarios:

• Building materials: Wrapping pallets of roofing tiles, metal profiles, and construction hardware.
• Metal parts and machinery: Securing components with sharp edges or uneven surfaces.
• Furniture and wood products: Protecting irregularly shaped items during transit.
• Recycling operations: Bundling scrap metal or abrasive materials.
• E-commerce fulfillment: Stabilizing mixed SKU pallets with protruding box edges.

Packaging and Export

Each roll is individually wrapped to protect against dust and moisture. Rolls are packed in export-grade cartons and palletized with strapping. Custom packaging and labeling are available for OEM orders. Export shipments can be arranged on FOB or DDP terms.

Frequently Asked Questions

1. What type of loads benefit most from puncture-resistant stretch film?

Loads with sharp corners, protruding edges, irregular shapes, or abrasive surfaces benefit most. This includes metal parts, ceramic tiles, wooden crates, building materials, and mixed SKU pallets where standard film may tear easily.

2. How does puncture resistance differ from tear resistance?

Puncture resistance refers to the film's ability to withstand initial penetration by a sharp object. Tear resistance refers to the film's ability to resist the propagation of an existing cut or puncture. Sharp load puncture film is formulated to improve both, but especially tear propagation resistance, so a small hole does not become a full-width tear.

3. Can puncture-resistant stretch film be used on automatic wrapping machines?

Yes. Machine-grade puncture-resistant film is designed for high-speed automatic wrappers and supports pre-stretch ratios up to 300%. Hand-grade film is also available for manual applications.

4. What thickness should I choose for sharp-edged loads?

For loads with sharp edges or heavy weight, a thickness of 20–30 μm is generally recommended. Lighter loads with moderate puncture risk may be wrapped with 17–20 μm film. We can suggest a specific thickness based on pallet weight and wrapping equipment.

5. How does Yuhong ensure product consistency between batches?

We control raw material quality, monitor extrusion parameters in real time, measure film thickness continuously, and perform finished roll testing for tear resistance, tensile strength, elongation, and cling force. Batch records are maintained for traceability.

6. Can I request a sample before placing a bulk order?

Yes. Sample rolls are available for testing on your own wrapping equipment. Please provide pallet dimensions, load weight, and machine type so we can recommend the most suitable sample.
