OPAQUE 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.

HOHL Heat sealable white pearlised BOPP film for packaging machines with low sealing initiation temperature and standard coefficient of friction. Suitable for high-quality rotogravure and flexographic printing, and lamination. ● High-quality solvent rotogravure and 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 flexible packaging products with pattern application of cold seal adhesive;
● for pattern application of cold seal adhesives on the OUT side of the film (if necessary).
● packaging for ice cream, chocolate bars, and candy that need protection against UV radiation.
HOHM White pearlised, glossy, heat sealable BOPP film with a medium coefficient of friction designed for metallisation and other specialty applications. ● Metallisation;
● Solvent rotogravure and flexographic printing;
● Lamination using polyurethane adhesives;
● May be used for UV-printing and UV-lamination (this requires careful selection of ink, primer, lacquer, adhesive and application techniques);
● substrate for self-adhesive label manufacturing;
● manufacturing of wrap-around labels (requires anti-static high-slip printing lacquer);
● for lamination of the inner layer of triplex laminate (with 2-sided activation);
● for two-sided printing (with 2-sided activation);
● for other specialty applications requiring similar properties.
HOHW White pearlised BOPP film with a very broad heat-sealing range and standard coefficient of friction for use in packaging machines. Suitable for high-quality rotogravure and flexographic printing, and lamination. ● High-quality solvent rotogravure and flexographic printing;
● solvent or solventless lamination using polyurethane adhesives;
● manufacturing of flexible food-packaging products;
● for high-speed heat sealing at 30–250 m/min (depending on packaging material thickness and machine model);
● low sealing initiation temperature for packaging "ice cream" and other heat-sensitive products;
● for use in vertical (VFFS) and high-speed horizontal (HFFS) packaging machines;
● packaging for ice cream, chocolate, candy, etc. that need protection against UV radiation.
● not for pattern application of cold seal adhesive on the OUT side of the film.
HWHL Heat sealable white opaque BOPP film with low sealing initiation temperature and standard coefficient of friction for use in packaging machines. Suitable for rotogravure, flexographic printing and lamination. ● High-quality solvent rotogravure and flexographic printing;

● flexible packaging with pattern-applied cold seal adhesive for single use or resealing;
● manufacturing of flexible flow-pack packaging for foods;
● self-adhesive label manufacturing;
● packaging for ice cream, chocolate bars, candy, etc.;
● not always suitable for use as a heat sealable film.
HWHW White opaque heat sealable BOPP film with a very broad heat-sealing range and low coefficient of friction for use in high-speed packaging machines. Suitable for rotogravure, flexographic printing and lamination. ● High-quality solvent rotogravure and flexographic printing;
● white film surface eliminates the need for white printing ink;
● solvent or solventless lamination using polyurethane adhesives;
● manufacturing of flexible food-packaging products;
● in some cases may substitute for packaging with pattern-applied cold seals;
