HTM 1340 B is a masterbatch which contains an antiblocking agent that has special features, in a polypropylene carrier. By making use of this masterbatch films free of marks are obtained upon winding. It is approved for food contact applications by both FDA and EU.
The optimal balance between the pore volume and the surface area of the added inorganic agent ensures a remarkable dispersion.
Minimal effect on the optical properties because of the additive’s refraction index is nearly comparable to the polyolefin’s one.
HTM 1340 B since not contains any migrating additive it’s especially intended for metallizable films, where the additives migration may cause problems in the metallization process.
Suitable for applications where a non-migrating additive may be required, as it features a constant and controlled size with the aim of avoiding irregularities in the film finish.
