Packaging films are manufactured from polymer materials-such as polyethylene-using blown or cast film processes; characterized by their lightweight nature and high flexibility, they meet diverse packaging requirements for food, consumer goods, and industrial products.
With a light transmittance exceeding 90%, these films offer clear visibility of the packaged contents. Additionally, the incorporation of a moisture-barrier layer limits the water vapor transmission rate to below 2g/(m²·24h), effectively extending the shelf life of moisture-sensitive items such as food and pharmaceuticals. During die-cutting, the film's tear strength of 35N/mm ensures clean, burr-free edges. In practical applications, the film is commonly used for flower packaging, dust covers for electronics, and lidding for food trays, while its suitability for upright packaging designs further enhances warehouse space utilization.
