Polymer additives for Food Packaging

IncroMax™ PS by Cargill acts as a processing aid and anti-scratch agent for styrenics. It provides mold release, scuff- and scratch resistance and surface quality enhancement. It migrates to the surface of the polymer where it forms a thin lubricating layer, which reduces the coefficient of friction between surfaces and reduces unwanted adhesion.

• It offers improved de-nesting and packing of preforms.
• It has a vegetable origin and can be dispersed evenly through the polymer in melt phase.
• It is easy to process and produces fewer rejected parts and less waste.
• It improves output rate, reduces temperature and extruder speeds in processing.
• IncroMax™ PS is suitable for use in PMMA and clear/opaque HIPS and GPPS.
• It is non-toxic and has no adverse effects on the physical properties of the polymer and reduces manufacturing noise.
• It is recommended for automotive-, houseware- and furniture plastics, cosmetics jars and bottles, food containers, trays, film production, and injection molding applications.
• It has a shelf life of 365 days.

It is a specially developed food approved additive. It is used in caps & closures, automotive, biopolymers, injection molding and film production.

• It is stable in applications exposed to UV light.
• It provides low visible bloom, scuff resistance and mold- & torque release properties.
• It is suitable for polyethylene (LDPE, LLDPE, HDPE), polypropylene (PP) and all polyolefins applications.
• The recommended dosage level is 0.1-0.25% for film grades, 0.2-0.5% for injection molding grades and upto 1% for compression molding grades.
• Incroslip™ SL has a shelf life of 2 year.

Incroslip™ B by Cargill is a specially developed high slip additive with exceptional stability and low odor properties. It is also used as a torque release agent in caps & closures. It can be dispersed evenly through the polymer in the melt phase.

• It migrates to the surface of the polymer where it forms a thin lubricating layer which reduces coefficient of friction between surfaces and prevents any unwanted adhesion.
• It offers low taste and exceptional oxidative stability.
• It exhibits anti-block and mold release properties.
• It is suitable for injection molding, polyolefin, ethylene vinyl acetate (EVA), polyvinylchloride (PVC) and biopolymers applications.
• The recommended dosage level is 0.1-0.2% for film and 0.2-0.5% for cap applications.
• Incroslip™ B has a shelf life of 1 year.

Incroslip™ C (Powder) by Cargill is a vegetable origin slip additive with exceptional stability, low odor and taste profile for sensitive applications. It is designed for high organoleptic stability applications where torque release is needed such as caps and closures for carbonated soft drinks. It offers scratch resistance and mold release.

• It is suitable for injection molding applications.
• It disperses evenly through the polymer in the melt phase.
• It migrates to the surface of the polymer where it forms a thin lubricating layer, reducing the coefficient of friction between surfaces and prevents any unwanted adhesion.
• The recommended dosage level is 0.1-0.2% for film and 0.2-0.5% for cap applications.
• It is used in polyolefins, EVA, and PVC.
• Incroslip™ C (Powder) has a shelf life of 1 year.

Atmer™ 7002 by Cargill is a vegetable-based anti-static agent. It is a 50% concentrate in polypropylene that provides lubrication and mold release benefits. It allows for better dispersion and overcomes complications encountered when using additives in their normal physical forms.

• Concentrates are added to the process like other resins, allowing for the additives to migrate to the surface of the polymer where they interact with atmospheric moisture, reducing surface resistivity and allowing dissipation of static charge.
• It exhibits reduction of fuming/smoking in processing.
• It offers better distribution of additives in base polymer, effective dosing of additives and less volatiles in processing.
• Atmer™ 7002 is recommended for PP closures & caps and film applications.
• Recommended dosage level is 0.5-1.6% in injection molding and sheet extrusion.
• It has a shelf life of 730 days.

Clearstrength® C-350 by Arkema Additives is a methylmethacrylate-butadiene-styrene (MBS) core-shell grade. It acts as an impact modifier.

• It offers very high impact resistance, even at low temperature and good clarity.
• It is compatible with polyvinyl chloride (PVC).
• It is recommended for use in rigid bottles.
• It is commonly used in PVC formulations for food.
• Clearstrength® C-350 is designed for use in calendered films and extruded sheets.

Clearstrength® C-140 by Arkema Additives is a methylmethacrylate-butadiene-styrene (MBS) core-shell grade and it acts as an impact modifier. It offers good impact resistance, high clarity, crease-whitening resistance with good toughness to vinyl formulations. It is compatible with polyvinyl chloride (PVC) for the production of transparent films and sheets. It is recommended for food packaging and pharmaceutical industry. Clearstrength® C-140 is designed for use in calendered film and extruded profiles.

Raven FC1 by Birla Carbon is a high performance, carbon black grade with high purity. It offers extremely low physical impurities, easy dispersability, long screen life, smooth surface finish and low moisture pick-up. It provides defect-free films and excellent chemical cleanliness. Raven FC1 is recommended for indirect food-contact plastics like packaging & containers, food processing equipment, cutlery, dishes and utensils. It complies with U.S. FDA 21 CFR 178.3297 indirect food-contact applications.

Raven P125 Ultra by Birla Carbon is a carbon black with low moisture pick-up. It exhibits easy dispersibility, long screen life, excellent organoleptic properties and smooth surface finish. It provides extremely low physical impurities, fast extrusion, improved mechanical durability and excellent chemical cleanliness. Typical applications include geomembranes & films, telecom jacketing and pressure-, irrigation & sewage pipes. Raven P125 Ultra is suitable for use in food contact applications due to its compliance with (EU) No. 10/2011.

Hyperform® HPN® 58ei by Milliken is a high-performance nucleating additive polypropylene homopolymer. It is designed to enhance the appearance of thermoformed packaging parts and sheets. It is suitable for processing by sheet extrusion and thermoforming.
