Manufacturing processes have become increasingly sophisticated over the years, allowing for fast and cost-effective production of a wide range of products. One of the most common methods used in the plastic film industry is lamination, which involves combining two or more layers of plastic films to create a single product. Lamination can be used to produce a variety of products, from food packaging to documents and other printed materials. In this article, we will explore the benefits of plastic film lamination in manufacturing and how it is used in the industry. Lamination is the process of combining two or more layers of plastic films to create a single product.
This process can be used to produce a variety of products, from food packaging to documents and other printed materials. The most common method used in the plastic film industry is extrusion lamination, which involves the extrusion of a low-density polyethylene adhesive between two film networks. This process is often used to combine a plastic film with another film, paper, or foil. One of the main benefits of lamination is that it can provide vital properties to multilayer plastic films, such as special barriers, coatings, tear resistance and protection for other layers of the film structure.
Laminated films can also improve food preservation and make products more attractive on store shelves. In addition, lamination can be used to produce a band with a hidden print, which is often used in flexible packaging applications. Another important use of lamination is in blown film extrusion, which is also known as tube film. This process involves the extrusion of a plastic through a circular matrix, followed by a “bubble-shaped” expansion. This method can be used to manufacture coextruded multilayer films for high-barrier applications, such as food packaging.
Lamination film is also used in industrial film conversion processes. This type of film has a low processing temperature and comes in glossy, matte, satin, light-blocking, less shiny and textured images. It is made from certain plastics that are combined together. Extrusion bonding is another method that involves the extrusion of one or two molten plastic films that are then combined with an aluminum sheet. In order to ensure that quality products are produced during the lamination process, there are several key areas that need to be closely monitored.
These include tests to check the adhesion of the laminate film, tear tests, fold tests and crush tests. Overall, lamination is an important process in the plastic film industry that can provide many benefits for manufacturers. It can be used to produce high-performance films with special barriers and coatings that can improve food preservation and make products more attractive on store shelves. In addition, it can be used in blown film extrusion and industrial film conversion processes. Water-tempered multilayer LLDPE, HDPE and PP blown film with a width range of 20 cm to 2.8 meters.
