Plastic Resin Suppliers Built for Consistency, Speed, and Color Accuracy

When your production schedule depends on material availability, consistent quality, and predictable performance, choosing the right plastic resin suppliers matters as much as choosing the right resin itself. Marval Industries, Inc. supports manufacturers with a full spectrum of resin distribution and compounding services—delivering prime resins, engineered compounds, alloys, color concentrates, and additives for today’s demanding plastic processes.

From injection molding and extrusion to blown film extrusion, blow molding, rotational molding, and thermoforming, we help customers maintain uptime, hit tight color targets, and keep finished parts performing exactly as specified.

One Partner for Prime Resin, Color Concentrates, and Compounds

Many manufacturers source prime resin from one supplier and color from another—then absorb the hidden costs of mismatched lead times, inconsistent lots, longer changeovers, and additional troubleshooting. Marval’s approach is simple: align the resin and color solution under one roof so your process stays stable and your team spends less time chasing variables.

As experienced plastic resin suppliers, we distribute:

Prime olefin and styrenic resins
Compounds and alloys
Color concentrates and masterbatch

This combination helps reduce downtime, streamline purchasing, and improve production consistency—especially when color control is a critical requirement.

Resin Distribution Designed for Just-In-Time Performance

Reliable resin supply is about more than inventory—it’s about logistics and execution. Marval’s operation is built for efficient handling and rapid fulfillment, including the ability to receive up to 35 hopper cars at our rail siding and support delivery with a sophisticated material handling system plus a dedicated fleet of bulk trucks and trailers.

That infrastructure allows us to provide Just-In-Time delivery—helping you avoid overstocking while still protecting your production schedule.

Industries We Commonly Support

Marval distributes materials to major firms across the following:

Personal care

Custom Compounding Capabilities That Scale

When off-the-shelf resin isn’t enough—because you need a specific color, additive package, appearance effect, processing behavior, or performance profile—custom compounding becomes the competitive advantage.

Marval provides custom compounding of engineering resins, alloys, elastomers, polystyrenes, polyolefins, polycarbonates, nylons, blends, and color concentrates. We’re equipped to handle high-volume production, processing over 35 million pounds per year with eight single-screw extruders and three twin-screw extruders.

Finished materials can be supplied as strand-cut pellets or underwater-cut pellets, depending on customer requirements and downstream processing needs.

Services Available Through Our Compounding Operation

Manufacturers rely on Marval for the following:

Masterbatch
Color compounding
Color matching
Resin design engineering
Formulation development
Engineering plastics compounding
Proprietary and custom compounds
Pellet classification
Post blending
Pellet drying
Pellet and powder blending
Henschel mixing

Whether you need small-batch development for a new launch or production-scale output for ongoing programs, our compounding process is structured to support repeatability and long-term consistency.

Color Compounding That Protects Brand and Shelf Impact

Color is not a “nice-to-have” in plastic products—it’s often a purchase driver. In packaging and consumer products, especially, slight visual shifts can impact perceived quality, brand consistency, and buying behavior. That’s why color matching isn’t just art—it’s engineering, process control, and repeatable execution.

Marval supports customers with:

Technical assistance in selecting the right color direction for the product and application
Expert knowledge of how different polymers and fibers behave with custom color solutions
Clear guidance on tradeoffs between processing methods (and how those choices impact appearance and consistency)

Color Technology and Process Control

Marval uses specialized color data software to match colors using FD&C pigments. That software integrates tightly with production equipment to maintain strong control over the finished result—helping customers achieve a consistent appearance across runs and locations.

Specialty Solutions: Additives, Anti-Static Polymers, and Eco-Friendly Resins

Many products require more than strength and color. They need material behavior that solves real-world problems—such as static control, improved handling, durability, compliance-driven choices, or sustainability goals.

Marval supports those needs through specialty options such as:

Anti-Static Polymers: When static build-up creates manufacturing issues (dust attraction, handling problems, or ESD-related concerns), anti-static solutions can help maintain product performance and protect downstream users.
Eco-Friendly Resins: If you’re working toward sustainability targets, material selection matters. Marval supports programs that require eco-friendlier resin options and can help align performance needs with responsible material choices.
MARVALOY: As creators of MARVALOY, Marval provides specialized materials and expertise developed for real manufacturing demands—supporting customers who need dependable performance and consistent output.

What to Look for in Plastic Resin Suppliers

Not every supplier is built to support the realities of production. When you evaluate plastic resin suppliers, consider these practical criteria.

Material access and breadth: Can they supply prime resin and the compound/color system you need?
Logistics capability: Do they have a reliable delivery infrastructure that supports your schedule?
Technical support: Can they help prevent issues—not just ship boxes?
Process alignment: Do they understand your molding or extrusion method and its sensitivities?
Consistency controls: Do they have systems for repeatability in color and compound performance?

Marval’s manufacturing capacity, distribution infrastructure, and color/compounding expertise are built to meet those requirements—especially for customers who can’t afford downtime, rework, or color drift.

Quality You Can Build On

Marval Industries provides the plastics industry with colorants, additives, compounds, and resins of exceptional quality. We pledge to manufacture and ship products that consistently meet customer specifications and aim to exceed expectations—because consistency is what keeps your production moving and your product looking right.
