Plastic Endwalls & Plugs

Our plastic plugs and endwalls offer dimensional stability and superior strength.

Uncompromising Protection & Performance

The dimensional stability and superior strength of our plastic core plugs and endwalls protect rolls and prevent fallout that damages both product and productivity. Available in many standard sizes, they can also be custom-made specifically for your requirements.

Endwall & Plug Product Descriptions

Endwall Packaging System

Endwall Packaging System

Sonoco plastic endwalls offer an alternative to plywood and corrugated endwall structures used to suspend very large rolls of product on pallets.

Features & Benefits

  • Improve roll and coil stackability
  • Offer unparalleled hub and stacking strength
  • Durable polystyrene construction resists damage
  • Reusable and recyclable


Our plastic endwalls are ideal for cleanroom and foodservice environments as well as for foil, paper and sensitive film applications that are particularly susceptible to damage—including flexible electronics or solar film. They also protect products such as TVs and battery separators.

Injection-Molded Plastic Plugs

Injection-Molded Plastic Plugs

Keep it simple. That’s what Sonoco had in mind for customers with our injection-molded plastic plugs.

Designed to complement our broad range of fiber, plastic and composite cores used for winding film, paper, textiles, foil, tape and specialty products, Sonoco’s plastic plugs provide the superior quality customers have come to expect from our products.

And, since you can rely on Sonoco for both cores and plugs—along with responsive service and support—you can eliminate the hassle of dealing with multiple suppliers. The end result is a customer-friendly packaging solution that meets your needs and provides simplicity in purchasing and inventory management.
