As a dedicated packaging supplier at Qingdao Lucentsea Business Co., Ltd., we specialize in pulp molded end plugs designed for reliable steel coil edge protection. These end plugs are produced from high-grade recycled paper pulp and are shaped to match coil outer diameters from 60 mm to 180 mm, which makes them adaptable for various coil packaging lines. The primary function of our pulp molded end plugs is to guard the sensitive edges of steel coils against impact, abrasion, and deformation during handling, shipping, and storage. By integrating them into your coil packaging process, you can significantly reduce the risk of product damage and lower overall packaging and logistics costs. Moreover, their eco-friendly material construction supports sustainable business goals without compromising mechanical strength.
Our pulp molded end plugs are developed with attention to both protection performance and operational convenience. They are light enough for workers to handle quickly, yet strong enough to endure the heavy compressive forces encountered in modern warehousing and container transport. The molded shape precisely cradles the coil edge, preventing sideways movement and reducing the chance of scratches on polished metal surfaces. We also understand that every packaging environment is different, so we offer customization in terms of size, thickness, surface finish, and printing to match your specific requirements. Whether you are packing slit coils, full-width coils, or other cylindrical metal products, these end plugs provide a cost-effective barrier between the hard coil edge and external forces.
Below are the key characteristics that make our pulp molded end plugs a smart choice for coil packaging professionals:
- Precision-formed fit for coil outer diameters of 60 mm through 180 mm, with customizable inner profiles to suit different coil core sizes.
- Molded pulp composition provides a natural cushion that absorbs shocks and vibration, protecting coil edges from dents and chipping.
- Smooth, rounded edge design helps prevent mechanical damage to the coil and avoids scratching even when the plug shifts slightly during transit.
- The lightweight pulp structure reduces shipping weight and safely disposes after use, as the material is fully recyclable and biodegradable.
- Excellent moisture tolerance resists condensation and mild dampness, lowering the risk of rust developing on the exposed coil surface.
- Tool-free installation and removal allow packaging staff to increase throughput and reduce downtime in high-volume packing operations.
- Optional moisture-resistant coatings and custom printing are available for branding, identification, or additional barrier protection.
- Dimensionally stable parts ensure consistent performance across each order, allowing reliable planning of packaging materials and cost prediction.

Adopting our pulp molded end plugs brings measurable operational advantages. End plugs made from pulp are abundantly available in cost-conscious packaging markets, but the true value lies in their consistent protection and low total cost. Compared with plastic caps or foam inserts, pulp molded end plugs perform favorably in terms of recycling convenience, storage footprint, and cash outlay per unit. They also reduce worker injury risk because there are no sharp plastic edges or brittle fragments. In the logistics chain, a simple but effective edge protection can be the difference between a complaint-free delivery and an expensive claim.
Applications for these end plugs extend across steel mills, service centers, coil processing plants, wire rod manufacturers, metal packaging companies, and export packing facilities. They are suitable for both vertical and horizontal coil orientation, and can be used together with stretch film, VCI paper, corrugated board, and steel strapping. Our engineering team can assist with product selection and suggest minor design adaptations when your coil dimensions fall outside the standard 60-180 mm range. All custom tooling is developed with short lead times so you can keep production schedules on track.
Quality assurance is an integral part of our services. We check incoming raw pulp for consistency, monitor molding parameters throughout the production run, and perform dimensional checks on finished pieces. As a trading company located in Qingdao, Shandong, China, we have direct access to efficient sea and rail logistics, which allows us to consolidate coil packaging products and ship them to major ports around the world. Our commitment to continuous improvement is reflected in our ISO9001 certified quality management system and our adherence to ISO14000 environmental management principles.
Since our establishment in 2026, we have built strong partnerships with buyers in North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, Western Europe, Northern and Southern Europe, Central America, South Asia, and the domestic Chinese market. Our customers rely on us for responsive communication, market-oriented pricing, and dependable delivery from the port of Qingdao. Whatever your coil edge protection needs may be, we are ready to provide samples, technical advice, and custom quotations that fit your business objectives.

Frequently Asked Questions
1. What are pulp molded end plugs used for?
Pulp molded end plugs are protective caps placed on both ends of steel coils or similar cylindrical metal products. They prevent direct contact between the coil edge and the surrounding packaging, shipping, or storage environment. This reduces scratches, dents, and edge deformation caused by impact, vibration, or the pressure of straps and wrappings.
2. What coil outer diameter range do you support?
Our standard pulp molded end plugs cover outer diameters from 60 mm to 180 mm. For unusual sizes outside this range, we welcome inquiries and can discuss custom tooling or modified molds. Please provide your exact coil O.D., wall thickness, and coil width so we can suggest the most suitable solution.
3. Are these end plugs fully recyclable?
Yes, the primary material is recycled pulp that is biodegradable and recyclable. If the end plugs have optional moisture-resistant coatings, the recycling process may be affected depending on the coating type. We can provide uncoated versions if you require strictly industrial paper recycling streams.
4. Can I order custom printed end plugs with my company logo?
Custom logos, color codes, and printed handling instructions are available upon request. These features help identify coil grades, destination ports, or processing lines. Our production team can adjust the printing method to ensure legible on easy-to-clean surfaces without adding excessive cost.
5. How do I choose the right thickness for my coil edge protection?
The appropriate thickness depends on the weight of the coil, the stacking height, the transport mode, and the surface finish requirements. Heavier coils often need thicker pulp sections to absorb impact. We recommend sending us your product parameters and handling conditions, and we will help you select an 8 mm, 10 mm, 12 mm, or other customized thickness.
6. Are samples available before bulk purchase?
Yes, samples are usually available. Please contact our sales team with your coil specifications and target quantity. We can produce a small batch of molded end plugs for field tests, and the sample cost can often be deducted from your first order, subject to mutual agreement.
7. What is your minimum order quantity?
The minimum order quantity can vary according to size, thickness, and customization requirements. Since we supply both standard and custom products, we kindly ask you to share your estimated annual usage or container loading plan. Our team will respond with a concrete MOQ and pricing structure within a short time.
8. How do pulp molded end plugs compare with plastic caps?
Pulp molded plugs offer a more sustainable, lightweight, and often lower-cost solution for many coil packaging operations. They are easier to compress and do not form sharp broken edges. Plastic caps may have better moisture resistance in extreme conditions, but our pulp products can be treated with water-resistant coatings for most standard logistics environments.
