As a result of its higher performance and functionality in comparison to conventional mono-layer films, multilayer coextruded composite films have brought about a revolution in the packaging sector. The purpose of this article is to investigate the various aspects of how multilayer coextruded composite films improve the performance of packaging from a variety of different perspectives. By delving into the complexities of film structure, material selection, barrier qualities, and extra functionalities, we are able to acquire a thorough grasp of the enormous benefits that these films bring to applications that include packaging.
Film Structure and Strength
The enhanced packaging performance of multilayer coextruded composite films is a direct result of the films’ distinctive structure, which contributes to the films’ strength. Composed of numerous layers of various materials, each layer has a distinct purpose, such as providing mechanical strength, puncture resistance, or tear resistance. The layers all work together to form the composition. These films demonstrate great strength and endurance, shielding the packaged product from the external forces that are encountered during storage, transit, and handling. This is accomplished by mixing a variety of materials, each of which possesses a unique set of features or characteristics.
Barrier Properties
Multilayer coextruded composite films are exceptional in their ability to provide an efficient barrier against external elements such as oxygen, moisture, and light with their barrier properties. Barrier materials, such as ethylene vinyl alcohol (EVOH), polyvinylidene chloride (PVDC), or aluminium foil, are strategically inserted into the structure of the film in order to limit the intrusion of oxygen, maintain the freshness of the product, and guard against rotting. These films provide the function of a dependable shield, ensuring that the quality of a wide variety of perishable commodities, such as food, pharmaceuticals, and sensitive electronic components, is maintained while also increasing the shelf life of these products.
Functions that can be customised
Multilayer coextruded composite films have the freedom to insert additional functions in order to fulfil certain packaging needs. To give one example, films can be manufactured to have excellent heat-sealing capabilities, which enables them to be sealed in a manner that is both efficient and secure throughout the packing process. Additional functions include anti-fog qualities, which prevent condensation and maintain product visibility, and antistatic properties, which protect electrostatic-sensitive objects. Both of these properties maintain product visibility. Having the capability to personalise films with specific capabilities not only improves the performance of packaging but also guarantees the safety and integrity of the products that are wrapped.
Printability & Branding
Multilayer coextruded composite films offer a superb surface for high-quality printing, which make it possible to create branding, product information, and visual appeal that is striking to the eye. In order to ensure precise reproduction of colours, logos, and designs, the film surface is smooth and constant. This contributes to an increase in both consumer attractiveness and recognition of the brand. It is also possible to engineer these films with specialised coatings in order to obtain particular effects, such as matte or gloss finishes, which further enhance the aesthetics of the packaging.
Considerations Regarding Sustainability and the Environment
Over the past few years, there has been a growing emphasis placed on environmentally responsible packaging possibilities. There are other benefits to be gained from using multilayer coextruded composite films in this direction. The utilisation of thinner layers of high-performance materials allows these films to lower the amount of material that is consumed while simultaneously maintaining or improving the performance of the packaging. Additionally, the capacity to insert components that are recyclable or biodegradable within the structure of the film contributes to the achievement of a circular economy and reduces the negative impact on the environment.
User Experience and Convenience
Multilayer coextruded composite films increase the performance of packaging by delivering a user experience that is both more convenient and more satisfying. Re-sealable closures, tear notches that are simple to open, and modified atmosphere packaging (MAP) valves that allow for regulated gas exchange are some of the features that may be designed into these films via engineering. Such characteristics improve product accessibility, guarantee that the product will remain fresh once it has been opened, and make it easier to control portion sizes, hence increasing customer pleasure and convenience.
Multilayer coextruded composite films have revolutionised packaging performance by providing superior strength, barrier qualities, customised functionality, printability, and sustainability. The complicated film structure, the choice of materials, and the additional features all contribute to an improvement in the efficiency of packing, the protection of products, and the overall experience for retailers and customers. While the packaging business continues to undergo change, multilayer coextruded composite films continue to be at the forefront of innovation. These films provide cutting-edge solutions to suit the varied requirements of a variety of industries, including as the food industry, the pharmaceutical industry, the personal care industry, and the electronics industry.
