Plastic packagings play an essential role in our modern lives. They help maintain the quality of sensitive products (i.e. electronics and fresh foods) during shipping and handling.
With minimal resources and waste, plastics provide the best protection in packaging applications. Various additives are used to improve the durability, flexibility, and strength of plastic packaging materials.
ChemPoint, partnered with Dow, offers you a range of PARALOID™ impact modifiers and processing aids that are engineered for superior performance in packaging plastics.
PARALOID™ Impact Modifiers by Resin Type
Polylactic Acid (PLA) and PLA Blends:
PLAs are among the most sustainable packaging materials. They combine the cost efficiency, environmental sustainability, and reliable performance in several packaging applications.
PARALOID™ BPM-520 is one of the highest performance impact modifiers for PLA resins and PLA blends. It provides an exceptional combination of impact strength, excellent colorability, and surface finish for injection molding applications.
PARALOID™ BPM-520 also provides high impact strength at room and sub-zero temperatures. Additionally, PARALOID BPM-520 can be used in compliance with the Commission Regulation (E.U.) No 10/2011 on plastics materials and articles intended to come into contact with food and with U.S. Food and Drug Administration (FDA) requirements.
The demand for engineered resins is on the rise due to their versatility and superior performance properties. PARALOID™ EXL 2330 and PARALOID™ EXL 3330 provide an excellent balance of impact resistance and modulus retention in various engineered resins.
PARALOID™ EXL 2330/3330 is a general-purpose acrylic core-shell impact modifier that is suitable for use in polycarbonate (P.C.), polyesters (PET, PBT, PPT), polyacetal, styrene-acrylonitrile (SAN), and blends of these thermoplastics. They also can be used in glass fiber reinforced nylons and thermoset epoxies.
PARALOID™ EXL 2330/3330offers high impact strength, excellent processability, weatherability, and well-defined particle size. PARALOID™ EXL 2330 is supplied in powder form and PARALOID™ EXL 3330 in pellet form.
Toughness of Polycarbonate and PC Blends
Polyvinyl Chloride (PVC) Resins:
PARALOID™ BTA Series is a range of MBS impact modifiers that provide exceptional impact resistance in clear PVC applications ranging from intermediate haze to the highest levels of transparency. PARALOID™ BTA grades are easy to incorporate into PVC formulations and reduce breakage during cutting and hold punching.
PARALOID™ BTA Products conform with the U.S. Food and Drug Administration (FDA) Regulation 21CFR 178.3790 governing their use in semi-rigid and rigid PVC plastics for food packaging and food contact applications.
PARALOID™ Processing Aids
Processing aids are specialty additives used in plastic formulations to enhance the flow and improve the dispersion of fillers in processing-filled polymer compounds. PARALOID™ offers a range of dispersible acrylic process aids that are excellent for use in various plastic packaging applications.
PARALOID™ Process Aids for Packaging Plastics:
PARALOID™ K-120ND is a readily dispersible acrylic processing aid that improves the processing of rigid and flexible vinyl compounds. It is excellent for use in vinyl packaging applications where clarity, rheology, and excellent dispersion are essential. It also offers the following features and benefits:
Readily dispersed in compounds without added gel
Shortened fusion time and more homogeneous melt for easier processing
Excellent melt strength and parison control
Increased output rates and improved production efficiency
Smooth glossy surfaces free of surface imperfections
Faster flexing and smooth-rolling in flexible calendared films
Complies with the U.S. Food and Drug Administration (FDA) regulations 21 CFR 177.1010 and 21 CFR 178.3790
PARALOID™ K-175 is an acrylic lubricating aid that functions as an external lubricant and a processing aid in vinyl formulations. It has no adverse effects on clarity compared to conventional lubricants that increase haze when incorporated into vinyl compounds. It also offers the following features and benefits:
Increased output rates and less scrap
Improved flow and reduced downtime for roll or mold cleanup
Improved thermal stability
Reduced downtime for roll or mold cleanup
High clarity, brilliance, and better parts appearance
Elimination of difficulties in post-finishing and enhanced post-decorative adhesion
Better weld line impact strength of injection-molded parts
Increased toughness in highly filled extrusions
Increased surface tension for printability
Compliant with the U.S. FDA Regulation 21 CFR 178.3790 for use in rigid and semi-rigid vinyl food-contact articles
PARALOID™ K-125 is an all-acrylic, general-purpose processing aid that offers outstanding efficiency in improving the processing characteristics of vinyl compounds. It also enhances processing properties with no adverse effects on impact strength, thermal stability, tensile properties, DTUFL, or electrical parts.
PARALOID™ K-125 is excellent for packaging applications as it provides a faster fusion of sheets, a shorter time to the smooth-rolling bank, and exceptional hot melt strength with low loading levels. It also offers the following features and benefits:
Improved productivity by reducing surging, decreased melt fracture and plate-out, faster takeoff, improved surface finish, and fewer rejects or shutdowns
Increased melt strength, faster fusion, and better edge formation
Increased sheet extensibility by a ratio of 5:1 in vinyl formulations
Compliant with FDA Regulation 21 CFR 178.3790 and 21 CFR 177.1010 for use in food contact applications
