BOPP film for packaging
BOPP is "Biaxially Oriented Polypropylene" acronym, BOPP film that is biaxially oriented polypropylene film.
BOPP film production is the first polymer polypropylene melt through the narrow head into a sheet or thick film, and then in a dedicated stretching machine, at a certain temperature and set the speed, simultaneously or in steps Stretching in both vertical directions (machine direction, transverse direction) and films made by suitable cooling or heat treatment or special processing (eg corona, coating, etc.).
bopp film rolls profile
Commonly used BOPP films include: general-purpose biaxially oriented polypropylene film, heat-sealed biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented polypropylene pearlescent film, biaxially oriented polypropylene metallized film, matting film, Book film, laser film, anti-counterfeit film and paper ball film.
bopp lamination film Advantage
pearl bopp film is a very important flexible packaging material, BOPP film colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency.
BOPP film surface can be low, the need for corona treatment before coating or printing. After corona treatment, BOPP film has good printing adaptability, can be color printing and get beautiful appearance effect, which is often used as a composite film surface material.
Production Process
BOPP film can be pipe or flat film production method. Different processing methods to get the BOPP film performance is not the same. The BOPP film produced by the flat film method has a higher tensile strength than the film method due to the large stretch ratio (up to 8-10), and the evenness of the film thickness is better.
application
Widely used in food, candy, cigarettes, tea, juice, milk, textiles and other packaging
