Masterbatch For Plastic Film

Author:admin    Source:未知    Pubdate:2018-06-23 15:48    Page View:

Plastic film is a thin continuous polymeric material. These thin plasticmembranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces.
Plastic films are used in a wide variety of applications. These include: packaging, plastic bags, labels, building construction, landscaping, electrical fabrication, photographic film, film stock for movies, video tape, etc.
 
Almost all plastics can be formed into a thin film. Some of the primary ones are:
a. Polyethylene – The most common plastic film is made of one of the varieties of polyethylene; Low-density polyethylene,Medium-density polyethylene, High-density polyethylene, and Linear low-density polyethylene.
b. Polypropylene – Polypropylene can be made a cast film, biaxially oriented film (BOPP), or as a uniaxially oriented film.
c. Polyester – BoPET is a biaxially oriented polyester film
d. Polyvinyl chloride – film can be with or without a Plasticizer
 
Plastic films are usually thermoplastics and are formed by melting for forming the film.
a.Cast – Plastics extrusion can cast film which is cooled or quenched then wound up on a roll.
b. Extruded film can be stretched, thinned, or oriented in one or two directions. Blown or tubular process forces air into an extruded ring to expand the film. Flat tenter lines stretch the extruded film before annealing.
c. Calender rolls can be used to form film from hot polymers
d. Solution deposition is another film forming process.
e. Skiving is used to scrape off a film from a solid core (sometimes used to make PTFE thread seal tape)
f. Coextrusion involves extruding two or more layers of dissimilar polymers into a single film
g. Lamination combines two or more films (or other materials) into a sandwich
h. Extrusion coating is used to form a film onto another film or substrate
 
Na2SO4 filler masterbatch, BaSO4 filler masterbatch, Talc filler masterbatch and CaCO3 filler masterbatch can be used in kinds of polyethylene and polypropylene film. It will reduce the production cost effectively. And Na2SO4 filler masterbatch and BaSO4 filler masterbatch will not influence the transparent of film, suitable for plastic shopping bag etc. 
Color masterbatch, black masterbatch and white masterbatch can be used for the coloring of plastic film, widely used in kinds of garbage bags, shopping bags etc.
