The laminated film is a combination of both Breathable film or Non-breathable film with non-woven fabrics made of poly-propylene or polyester in two or more layers using adhesive or heat.

As a compound film that is both Air-permable and waterproof, and effective as a non-woven fabric as it is soft as cloth, the laminated film is widely used in disposable products that must be luxuriously smooth to the touch.

It is classified into four types according to the compounding method:

▶ Heatsealing laminated film
This film is produced by adhering the film to the non-woven fabric by the use of heat. The film is a highly priced and a quality competitive product as it does not use adhesives.

▶ Hot melt applicator laminated film
This laminated film is produced by adhering the film to the non-woven fabric using a hot melt applicator. This film has superior softness and high adhesive strength.

▶ Solvent Hot melt laminated film
It refers to a method in which the film and non-woven fabric is adhered using roll coater. It is widely applied to hygienic and medical films like stripe-laminated film. It does not need hardening or aging process.

▶ Cold Glue laminated film
As a method to adhere the film and non-woven fabric using glue adhesive, this film has strong adhesive power and requires a certain hardening and aging time.
