Flexible High Barrier Top Lidding Film
Top films are a type of high-performance lamination or coextrusion used various applications, particularly the packaging industry. Lidding films are designed to provide excellent sealing properties and can be used with different substrates such as PE, PP, PS PET, PVC, and Aluminum.
One of the key features of top films is their ability to form a strong seal when used in packaging. They can be used in combination with heat-sealing methods to create a secure and tamper-evident package. Additionally, some top films are equipped with an "easy peel" feature, which allows for effortless opening of the package.
Another important characteristic of top films is their barrier properties. They are co-extruded films, meaning that they consist of multiple layers with different properties. The inclusion of advanced barrier layers, such as EVOH (ethylene vinyl alcohol) or PA (polyamide), enhances the film's ability to prevent the transmission of oxygen and moisture. This helps to preserve the freshness of the packaged product and extend its shelf life.
Top lidding films are also designed to meet the requirements of various packaging machines. They are compatible with different types of automatic machines used in packaging, including top web and modified atmosphere packaging (MAP) tray lidding machines, flow pack applications, and thermoform-fill seal lines. This ensures optimal performance and efficiency during the packaging process.
Here are some key features for lidding film.
1. Lidding films are designed to have a wide of oxygen and moisture transmission rates. This helps in extending the shelf life of the packaged product by minimizing the exposure to oxygen and moisture.
- Lidding films offer excellent gloss and clarity, providing an attractive and appealing appearance to the packaged product.
- Lidding films possess exceptional aroma retention power, ensuring that the aroma and flavor of the product are preserved.
- Lidding films have high puncture resistance, enabling them to protect the product from damage during handling. They also exhibit good hot tack and sealing properties, ensuring secure and efficient sealing of the package.
- Despite being thin, lidding films demonstrate superior mechanical properties, such as tensile strength and flexibility, allowing for ease of handling and protection of the packaged product.
- Lidding films have high temperature resistance, making them suitable for use in applications that involve heating or exposure to elevated temperatures.
- Lidding films offer additional functionalities like easy peel, UV resistance, anti-fog properties, and special coatings based on specific product requirements.
- Lidding films provide a wide variety of sealing options, allowing compatibility with different substrate materials such as PP, PE, PET, PVC, Aluminum, PS, etc. They may also feature a special seal layer designed to enable sealing at low temperatures, particularly with liquid products.
Top lidding films are high-performance lamination films used for packaging applications. They provide excellent sealing properties, advanced barrier layers, and are compatible with various packaging machines. These films are commonly used in industries where product freshness, shelf life, and secure packaging are crucial factors.
