Yulin Yiwei Packaging Materials Co., Ltd. Stretch Film and Wrap Film Product Description

I. Product Overview
The stretch film and wrap film produced by Yulin Yiwei Packaging Materials Co., Ltd. are high-performance packaging materials manufactured using advanced processes, specifically designed for cargo securing, dust prevention, moisture resistance, and transportation protection. Stretch film (also known as stretch wrap) uses high-strength polyethylene (PE) as the primary raw material, achieving high extensibility and self-adhesion through pre-stretching technology; wrap film combines both stretching and adhesive properties, making it suitable for bundling and sealing various types of goods. The products are widely used in logistics, warehousing, manufacturing, and other fields, meeting the packaging needs of different industries.

As a professional adhesive products manufacturer established in 2019, Yulin Yiwei has become a long-term partner for customers nationwide thanks to its stable quality, flexible customization services, and high cost-effectiveness. The factory operates under an ISO-standardized management system, ensuring full-process quality control from raw materials to finished products.

II. Product Features and Performance Advantages
1. High Stretchability and Puncture Resistance
The stretch film utilizes multi-layer co-extrusion technology, achieving a stretch rate of 200%-300%, reducing material usage and packaging costs through pre-stretching during the wrapping process. Its excellent puncture resistance effectively protects goods from damage by sharp objects, making it particularly suitable for bundling irregularly shaped or heavy goods.

2. Self-Adhesion and Stability
The wrap film is coated with a high-viscosity resin layer, enabling tight adhesion between multiple layers without the need for glue. The adhesion is durable and uniform, preventing loosening during transportation. The product's temperature resistance ranges from -10℃ to 60℃, adapting to storage and transportation needs in various climatic environments.

3. Environmental Friendliness and Safety
The film materials comply with environmental standards, are non-toxic and free of irritating odors, making them suitable for industries with strict hygiene requirements such as food and pharmaceuticals. Additionally, the products are recyclable, reducing the environmental impact of packaging waste.

4. Diverse Application Scenarios
Based on usage methods, the films are divided into hand-use film and machine-use film:
Hand-use film: Thickness 15-20μm, width 50-500mm, suitable for manual packaging of small batches or lightweight goods.
Machine-use film: Thickness 20-30μm, width 500-1000mm, compatible with automated production lines to enhance packaging efficiency.
