PE filmmaker production plastic film classification is as follows:
1: Bidirectional stretch polypropylene film(BOPP)
2:Low-density polyethylene film(LDPE)
3:Polyester film(PET)
4:Nylon film(PA)
5:Streaming polypropylene film(CPP)
6:Aluminum-plated film
There are no uniform regulations for the classification of plastic film.Generally,there are three types of classification methods for people.
(1)The raw materials are classified by plastic film for molding.
(2)Classification according to the use of plastic film is classified as agricultural film (according to its specific use,can also be divided into ground membrane and large shed film),packaging film(according to its specific use,can also be divided into food packaging film and various industrial products packaging packaging Film,etc.)and breathable film,water-soluble film,and film with piezoelectric performance with special uses of specialty and special uses.
(3)Classification according to the molding method of the plastic film is squeezed out and plasticized,and then the film that blows plastic molding is called blowing plastic film;Posterial film;thin film made of several rollers on the pressurized machine,which is called a thin film;the thin film that stretches the thick sheet is called the stretch film.
In addition,there is a classification according to the layered structure of the film,which can be divided into single-layer membrane and multi-layer composite film.
