The antibacterial masterbatch is added during the melt processing of the final product in the range of 1 to 10 wt.%, depends on the application and type of the products. The antibacterial properties of the film and solid container can be evaluated according to ISO 22196:2011. According to the standards, the R-value for this product is about 2.5. It’s worth to state that the antibacterial properties is assigned when the R-value is greater than 2. The masterbatch is FDA approved and does not make any human skin sensitivity. 

B. P. Sharif Co. products, trade name of Polysharif®, is supplied to the market as Functional Polymeric Masterbatch Granules for the purpose of doing a function and duty in polymeric final products. One of the most useful masterbatch is Polysharif-O2Block Masterbatch which can be employed in food packaging as trays and flexible films. The base of the masterbatch is low density polyethylene (LDPE) or polyamide (PA). The O2block masterbatch is added during the melt processing of the final product in the range of 1 to 10 wt.%, depends on the application and type of the products. Utilizing this product, the oxygen transmission rate (OTR) of the polymeric film can be reduced dramatically. The OTR properties of the film and solid container can be evaluated according to ISO 15015-2:2003. According to the standards, the OTR value is less than 100 cc/m2 /24 hr. The masterbatch is FDA approved and contains clay nano-materials and Iron compounds.

B. P. Sharif Co. products, trade name of Polysharif®, is supplied to the market as Functional Polymeric Masterbatch Granules for the purpose of doing a function and duty in polymeric final products. One of the most useful masterbatch is Polysharif-antifog Masterbatch which can be employed in food packaging and green house films. The base of the masterbatch is low or high density polyethylene (PE) and polypropylene (PP). The antifog masterbatch is added during the melt processing of the final product in the range of 1 to 10 wt.%, depends on the application and type of the products. The antifog properties of the film can be induced immediately after the manufacturing process or a few hours after the process. It’s worth to state that the antifog properties caused by this masterbatch is permanent and can not be destroyed after mechanical abrasion of the products. The masterbatch is FDA approved and does not make any human skin sensitivity. 

Ethylene is a gas released by some fresh produces that causes produce to ripen faster. Some Fresh Produces are more sensitive to ethylene than the others. Ethylene, also known as the ‘death or ripening hormone’ plays a role in many processes of plant growth, development and eventually spoilage. The Ethylene absorber masterbatch can be used 1 to 10 wt.% in food packaging production. The ethylene absorber inside the packaging wall can get the released ethylene gas trapped inside the packaging and inhibit fast spoilage of the fresh produces. 

When two or more layers of plastic stick together during production or storage, it can be a big challenge during manufacturing of polyethylene (PE) films.

Antiblock Additive masterbatch using nano-particles can solve this problem. By creating nano-roughness on the polymer surface sticking of the films is inhibited. 

Polypropylene (PP) fibers, widely utilized in nonwoven industry, have highly hydrophobic surface properties. Therefore, a modification in order to create a polar surface is an important issue where wettability and adhesion properties are required. PP has a very low value of the surface free energy and, consequently, has very weak hydrophilic properties. In many industrial applications there is a need to modify the polymer surface with keeping their desired unchanged bulk properties. Chemical treatment of the surfaces is the most often used method for inducing, hydrophilicity. In conventional methods, the produced nonwoven fabric will be impregnated via specific solution passing through a bath and subsequent drying and rolling. The hydrophilic properties induced by this method is temporary, costly and may make smell during water absorption. However, the economical-technical requirements, force the industry to search alternative efficient methods. 

Our special way to impart surface hydrophilicity into polypropylene is blending of the melt additives during the fiber spinning process. In fact, the hydrophilic masterbatch, containing ologomeric additives, is added during the melt processing of the final product fabrics in the range of 10 to 15 wt.%, depends on the application and type of the products. The hydrophilic properties of the fabric can be induced immediately after the manufacturing process. According to our researches, oligomeric additives, spun with host polymer, migrate to surface and generate surface hydrophilicity at low concentration without altering bulk properties. The additives migrate to the surface gradually leading to a durable hydrophilic PP surface. 

B P Sharif Company special transparent nano-Filler Masterbatch was created to make cheaper polymeric final products without any opacity. The  transparency are very well applied into PE/PP/PS/ABS, which improve the transparency and brightening of the plastic.  Nano transparent filler masterbatch can be loaded  with 10-30% dosage which will not affect the virgin material transparency as well as mechanical properties. 

High transparent nano-based filler masterbatch with good dispersion ability, easily used without any change of processing conditions. Interestingly, it can also improve mechanical properties of the final product.
