Self-adhesive stretch film, also known as elastic film or wrap film, is a highly versatile packaging solution designed to securely wrap and protect goods during transportation. With superior tensile strength, excellent tear resistance, and strong retraction memory, it ensures that items remain tightly wrapped without the need for heat shrinking. This makes it an energy-efficient and cost-effective alternative to traditional packaging methods.
The film is typically produced using a three-layer co-extrusion casting process, meeting international environmental and health standards. It is available in single- or double-sided adhesive versions, allowing for flexible use in various industries. Its high transparency makes it easy to identify packaged products, reducing errors in distribution and improving overall logistics efficiency. Additionally, it offers excellent dustproof, waterproof, and anti-theft properties, making it ideal for protecting a wide range of goods.
Common applications include packaging for industrial products, building materials, paper, tobacco, agricultural bags, and more. The material is made from imported linear low-density polyethylene (LLDPE) resin combined with special adhesion agents, resulting in a product that is both durable and highly elastic. It can be stretched around objects of any shape, eliminating the need for tying and reducing the risk of damage.
Manual application of self-adhesive stretch film is simple and efficient, requiring only one person to hold a reel with a damping brake while wrapping the item. For large-scale operations, machine winding is recommended, offering higher productivity, consistent quality, and faster packaging speeds.
Key advantages of self-adhesive stretch film include:
1. Excellent tensile strength, clarity, and uniform thickness.
2. Environmentally friendly, odorless, and non-toxic, suitable for direct contact with products.
3. High longitudinal stretchability, good resilience, and strong transverse tear resistance.
4. Can be manufactured as single-sided adhesive to reduce noise and minimize dust and dirt during transport.
5. Utilizes a dual-layer co-extrusion system to optimize the performance of each polymer component, enhancing transparency, tensile strength, and puncture resistance.
Whether used manually or with machinery, self-adhesive stretch film is a modern and effective solution for securing and protecting goods throughout the supply chain. Its versatility, durability, and eco-friendly nature make it a popular choice across multiple industries.
