What is an Extrusion and Lamination Machine?

A extrusion and lamination machine is a piece of converting equipment that uses an extruder to force melted thermoplastic resin between two substrates.extrusion and lamination machine This is done to create a multi-ply laminated structure that can meet the specific needs of various industries such as flexible packaging, food and beverages, and more. Extrusion lamination offers a number of benefits including increased barrier properties, strength, printability, and appearance. It also provides improved protection against moisture, vapors, and aromas. Additionally, it can help to reduce costs and time by eliminating the need for off-gassing and drying processes.

Unlike other traditional lamination methods such as adhesive lamination, this technique can use a wide variety of materials, such as plastic, foil, paper, and aluminum.extrusion and lamination machine This makes it possible to produce products with a high degree of customization and functionality. It can also be used to produce products with different levels of stiffness and strength.

The process of lamination is usually done through heat and pressure. The substrates are then bonded together to form a single compound structure. The end product can then be used for a variety of applications, such as packaging, graphic arts, construction, and more. There are several different types of lamination, such as thermal, dry, extrusion, and liquid. Each type of lamination has its own advantages and disadvantages, depending on the type of material that is being used.

One of the most common converting technologies is called extrusion coating. This involves the simultaneous extrusion of two different layers of molten polymer to combine them into a laminated material. This material can then be used to manufacture a variety of products, including bags, film, and other flexible packaging.

There are a number of benefits associated with using this type of converting technology, including increased yields, pellets-to-product savings, and stock efficiency. Additionally, it is often more cost effective than adhesive lamination, particularly when you are working with thinner materials.

BOBST offers fully integrated extrusion coating and lamination lines that can handle a wide range of materials from thin films and aluminum foils to heavyweight papers and boards. The key to success in these applications is an understanding of the materials and their behavior during the extrusion process. For example, metalized films should be run with a lower temperature than non-metalized film to avoid differential expansion, which can cause crazing and other defects.

In addition, it is important to consider the type of blown film resin that will be used in the extrusion coating process. A softer, more flexible LDPE may be easier to run than a harder, stronger, metallocene catalyst blown film. It is also important to consider whether you want to run your blown film as a pure layer, a coextrusion arrangement, or a combination of both. Davis-Standard can help you determine which option is best for your application.
