The pearlescent qualities of biaxially stretched polypropylene film make it a desirable material in packaging due to its attractive appearance
and optical performance.
Biaxially stretched polypropylene pearlescent film can vary in opacity, as it is achieved by adding pearlescent pigments or through special
treatment methods on the BOPP film. Some may have an opaque finish and are often used for packaging that requires coverage or decoration.
While it has good barrier properties, biaxially stretched polypropylene pearlescent film maintains product visibility due to its transparent or semi-
transparent finish when combined with a pearlescent effect.
With its good mechanical properties, including high tensile strength and toughness, and heat sealing performance, this environmentally-friendly
and recyclable material is ideal for packaging food, medicine, cosmetics, and electronic products.
Biaxially stretched polypropylene pearlescent film can also be used for printing, such as labels, business cards, and posters.
Additionally, it has decorative applications such as wallpaper and floor film, due to its good wear resistance and decorative effect.
