TRANSPARENT GENERAL-PURPOSE FILMS

Product description
Biaxially oriented polypropylene films are polymer films manufactured by extrusion followed by biaxial orientation. BOPP films are multi-layer films with polypropylene core and tie layers. Orientation in two perpendicular directions ensures that BOPP films have good mechanical properties in both directions. The outer surfaces of BOPP films are formed by co-extrusion with skin co-polymer layers (either on one or on both sides). Film layers may consist of a mix of polymers and functional additives that adjust barrier properties, opacity, whiteness, matting or gloss, thus controlling film properties, and therefore defining the range of available film products. In addition to co-extrusion, both or one of the film surfaces may be corona- or flame- treated to activate them and make suitable for printing and lamination.

Grade Description Application Technical documents
HGPL Heat sealable transparent BOPP film for packaging machines, with standard coefficient of friction and low sealing initiation temperature. Suitable for high-quality rotogravure and flexographic printing, and lamination. ● High-quality rotogravure and solvent flexographic printing;
● solvent or solventless lamination using polyurethane adhesives;
● manufacturing of flexible food-packaging products;
● for use in vertical (VFFS) and horizontal (HFFS) packaging machines;
● manufacturing of decorative floral packaging and gift wrapping products;
● for pattern application of cold seal adhesives on the OUT side of the film (if necessary).
HGFL Heat sealable transparent BOPP film with low sealing initiation temperature for specialty applications with high coefficient of friction; suitable for high-quality rotogravure and flexographic printing, and lamination ● High-quality rotogravure and solvent flexographic printing;
● solvent or solventless lamination using polyurethane adhesives;
● manufacturing of flexible food-packaging products;
● for use in vertical (VFFS) and horizontal (HFFS) packaging machines;
● for lamination with PE and CPP films with high contents of slip additives;
● for reduction of the impact from slip additives migration from PE or CPP films to BOPP films that greatly reduces the coefficient of friction; The high coefficient of friction enjoyed by HGFL provides a margin of safety under such circumstances;
● for packaging operations that involve banding several packages filled with products (e. g., pasta packaging);
● for holding packages together and preventing their sliding (if necessary);
● other applications that require mitigation of sliding of flexible packaging along BOPP film surface;
● for pattern application of cold seal adhesives on the OUT side of the film (if necessary).
HGHL Heat sealable transparent BOPP film with low sealing initiation temperature and low coefficient of friction for high-speed packaging machines; suitable for high-quality rotogravure and flexographic printing, and lamination. ● High-quality rotogravure and solvent flexographic printing;
● solvent or solventless lamination using polyurethane adhesives;
● manufacturing of flexible food-packaging products;
● for high-speed vertical (VFFS) and horizontal (HFFS) packaging machines;
