PE and PP raffia is used in a wide range of applications, such as PP bags, Rachel bags, shade nets, laminated PP bags, greenhouse twines, and Flexible Intermediate Bulk Containers (FIBC or ‘big bags’).
FIBC bags are most often made of thick woven polypropylene fabric (usually 70-250 GSM), either coated or uncoated. Their qualities of strength, flexibility, resistance, product protection, space optimization and handling agility make them suitable for packaging dry, flowable products like sand, fertilizer and plastic granules. Our extensive experience working with packaging additives and polypropylene fabric has enabled us to develop a wide range of additives to cover your specific needs.
The process sensitivity of raffia production makes the selection of MB critically important. Our UV MB are designed to reduce water carry-over (WCO) and to maintain high retention. Our colors are developed from high-heat-resistant pigments with good dispersion, and our white MB contains outdoor TiO2, to prevent polymer degradation and yellowish effect.
Tosaf offers both food-approved and non-food-approved MB, according to customer requirements. To ensure regulatory compliance, we provide the necessary documentation, such as REACH and ROHS, with all our products.
Due to the sensitivity of this application, even a small reduction in the UV content of the fabric can lead to major failure. We ensure that every batch of production is carefully monitored, and the UV concentration meets your precise specifications.
Flame Retardants
Considering new regulations around the world, our high concentration FR masterbatches including halogen-based and halogen-free solutions, provide self-extinguishing properties and meet market needs.
Recyclable
Halogen free option
Suppressed smoke formation
Good process ability
Reduced incidence of fire
Anti Split
We offer mineral-filled masterbatches, usually based on homopolymer polypropylene resin, to achieve anti-split of the fibers during production
White Masterbatch
Comprehensive Product Range
Thermal Stability
Excellent Dispersion
Highly Concentrated White MB
Coating Compounds
Designed to coat both sides of the fabric, our coating compound provides excellent sticking properties, easy processability (without ‘necking’), strength and stiffness.
Provides excellent sticking properties
Easy processability
UV Light Stabilizer Masterbatch
Long-term exposure to UV radiation compromises the integrity of plastic, making it brittle and prone to cracking or breaking. The masterbatches in Tosaf’s UV light stabilizer range eliminate or vastly reduce the effects of UV radiation and photo-oxidation, offering long-term polymer protection.
Prevents premature polymer degrading and failure
Minimizes deterioration of mechanical properties
Extends high-quality surface appearance
Color Masterbatch
Finding an exact color match requires wide-ranging, working knowledge of pigments, polymers and additives. Working with an extensive global network of renowned research partners, Tosaf’s experts have the technical competence to create complex colors for use in virtually any polymer, in a range of applications, across different industries.
Backed by vast technical knowhow
Complex colors for use in virtually all polymers
Orders as small as 1 kg for any of our 500 standard colors
Anti-Static Additive
Eliminate the static charge that can cause electric shocks and cause dust to attract to the plastic surface. The migrating molecules in Tosaf’s anti-static masterbatch migrate to the surface, attracting a thin layer of water molecules from the air sufficiently conductive to dissipate the charge. Food approved with no specific migration limit, this solution has an immediate and permanent anti-static effect.
Suitable for use in a variety of relative humidity levels, from dry to high moisture
Suitable for a broad range of polyolefin and some polystyrene polymers
Not corrosive to PC
Food approved with no specific migration limit
