Two Layer Film, is a 2-layered plastic film. It looks like a single layer film but it is actually composed of 2 separate layers of films. These films can be of different compositions depending on the use and the packaging and cost needs of the clients. Typically, the top layer is the printed layer which is made of PET film or BOPP film. Sometimes it is Nylon film. The second layer is usually a PE film, or CPP film. The CPP film may be metalized to give extra barrier protection properties.
Two layer films are usually used for food products that will have shelf lives of 1 – 4 months. Also, this type of film is quite inexpensive and is so used extensively in a wide variety of uses, eg. detergents, soaps, cosmetics, tissue and nappy coverings, seed products, pesticides, chemicals, medicines etc. etc.
