Plastic Core Plugs, Film Cores & Endwalls
Plastic Core Plugs, Film Cores & Endwalls
Sonoco plastic core plugs and endwalls protect film, paper, foil, textile, and specialty-product rolls from fallout, crushing, distortion and surface damage during winding, shipping, stacking and storage. As an experienced fiber and plastic core manufacturer, Sonoco offers standard and custom solutions built for strength, dimensional stability and reliable roll protection.
Plastic Core Plugs and Endwalls for Roll Protection
When rolls need added support beyond the core itself, Sonoco plastic core plugs and plastic endwalls help stabilize the roll package for movement through the supply chain. Available in standard sizes and custom configurations, these components can be matched to roll weight, core size, stacking method and suspension requirements.
Sonoco roll protection solutions support:
- Core reinforcement for shipping, stacking and storage
- Fallout prevention during handling and transport
- Roll stacking and suspension applications
- Protection for film, paper, foil, textile, tape and specialty products
- Standard sizes and custom manufacturing support from an experienced plastic core manufacturer
Plastic Film Winding Cores for High-Speed Roll Applications
For high-speed film applications, Sonoco plastic film winding cores are designed to support consistent winding and unwinding while helping to protect internal diameter integrity. Manufactured from durable plastics, including polypropylene, styrene, ethylene and acrylonitrile butadiene styrene, these cores support sensitive films such as window, polyvinyl butyral (PVB) safety glass, paint protection, geomembrane, flexible, medical-grade and electronics films.
Sonoco plastic film winding cores support:
- 3-inch to 6-inch diameter requirements
- Dust- and moisture-free performance in clean environments
- Customer-specified lengths and winding speeds
- Crush resistance for packaging, protection and reuse
- Total indicator runout (TIR) control for straightness
- Ovality control for precise roundness
- Smooth surface qualities designed to minimize markings
- Reusability and reclamation programs where they are applicable
When paired with compatible plastic core plugs and endwalls, Sonoco film winding cores help create a more complete protection system while simplifying purchasing, fit and inventory management. Sonoco can help align cores, plugs and endwalls to application requirements.
Plastic Endwalls for Stacking, Suspending and Shipping Large Rolls
Sonoco plastic endwalls provide a durable alternative to plywood and corrugated structures for large rolls that need stable pallet suspension, clean handling and reliable stacking strength. Depending on the system, endwalls may also accommodate multiple core sizes, helping teams streamline roll packaging across related applications.
Sonoco plastic endwalls support:
- Improved roll and coil stackability
- Strong hub and stacking performance for large roll suspension
- Durable polystyrene construction that resists damage
- Reusable and recyclable packaging goals
- Cleanroom and foodservice environments
- Foil, paper, sensitive film, flexible electronics, solar film, TVs and battery separator applications
Injection-Molded Plastic Core Plugs
Sonoco plastic core plugs are designed to complement fiber, plastic and composite cores used for winding film, paper, textiles, foil, tape and specialty products. Available in a range of designs, these plugs help buyers match fit, load support and roll-handling requirements without managing multiple suppliers.
Sonoco injection-molded core plugs support:
- Single or double plug designs for different roll-protection and stacking needs
- Suspension pad plugs for roll suspension applications
- Center bore sizes from 1.05 inches to 3 inches
- Core plugs for 3-inch and 6-inch inside diameters
- Light- to heavy-duty load requirements
- Flanged or non-flanged options based on fit and support needs
- Undersized or oversized plugs for loose or snug fit requirements
- Recycled or virgin plastic options
Sonoco can help align plastic plugs with core type, roll weight, handling method and packaging requirements.

Frequently Asked Questions About Plastic Core Plugs
What are plastic core plugs used for?
Plastic core plugs reinforce and protect the open ends of roll cores during winding, shipping, storage or suspension. They can help reduce crushing, distortion, fallout and product damage, with options for 3-inch and 6-inch core inside diameters, light- to heavy-duty loads, single or double-plug designs and flanged or non-flanged configurations.
What is the difference between plastic core plugs and plastic endwalls?
Plastic core plugs fit into or support the roll core, while plastic endwalls help suspend, stack or stabilize larger rolls on pallets. Plugs are typically used for core support, fit and roll-end reinforcement, while endwalls are used for roll suspension, stackability and palletized handling.
Can plastic core plugs be customized for different roll sizes or fit requirements?
Yes. As an experienced plastic core manufacturer, Sonoco offers standard and custom plug options, including suspension pad plugs, center bore sizes from 1.05 inches to 3 inches, core plugs for 3-inch and 6-inch inside diameters, single or double designs, recycled or virgin plastic, flanged or non-flanged options and under- or oversized plugs for loose or snug fit requirements.
