Biaxially oriented polypropylene (BOPP) films are widely used for the packaging of biscuits, confectionary, snacks, cereals, salads & fresh products, overwraps for tobacco and perfumes, petcare etc. which are very sensitive to humidity and oxygen. The sealability of BOPP films is obtained by coextrusion of different types of polypropylene. Sometimes, the sealing and the barrier properties are not sufficient to conveniently close the package and to give good protection to the food.
|
 |
 |
For these reasons, most of the BOPP film producers have developed DIOFAN® coated structures which give good sealing properties as well as enhanced water vapor or gas barrier. BOPP films coated with DIOFAN® on either one or both sides can be found in a variety of applications.

Technical Data Sheet |
 |
DIOFAN® A 036 |
DIOFAN A 036 is a PVDC latex used as a flexible under layer for coating on polymer films, paper and cardboard, to be covered with an appropriate topcoat. |
|
| |
DIOFAN® A 050 |
DIOFAN A 050 is a standard grade PVDC latex for coating on various substrates. It is generally used as a topcoat on paper and cardboard. |
|
| |
DIOFAN® A 115 |
DIOFAN A 115 is a PVDC latex for use as a flexible topcoat on BOPP. In addition to barrier and sealing properties, this grade is well suited for printing. It is used also on other substrates: paper, paper/LDPE, cardboard and other plastic films.

| |
DIOFAN® A 297 |
Diofan A 297 is an aqueous anionic dispersion, acidic and film-forming, of a copolymer with a high vinylidene chloride content. |
|
| |
IXAN® SGA-1 |
IXAN SGA-1 is a copolymer based on vinylidene chloride and vinyl chloride monomers. The unrivalled performance of IXAN SGA-1 is due to the combination of its outstanding characteristics as adhesion combined with barrier as primer on a wide range of substrates, binding capabilities in e.g. print inks and paints, applicable as protective varnishes, solubility in a wide range of common organic solvents at room temperature, barrier properties and chemical resistance of the coatings and coverings, and heat-sealability, transparency, and glossiness of the coatings. |
