Lap-Over Strapping Seals – FAQ
Find answers to common questions about lap over seals.
Lap-over strapping seals are metal clips used to secure strapping around boxes, pallets, or bundles. The strapping laps over itself inside the seal, which is then crimped with a sealing tool to hold the load tightly.
- Securing heavy or medium-duty loads
- Unitising pallets for shipping and storage
- Bundling boxes or materials where a strong, reliable seal is needed
- Wrap the strapping around the package or pallet.
- Overlap the strap ends and insert them into the lap-over seal.
- Use a manual or pneumatic crimping/sealing tool to press the seal and lock the strapping in place.
They are usually made from galvanised or zinc-coated steel for corrosion resistance and durability.
Types of Lap Over Strapping Seals
Lap-over strapping seals provide a secure and durable method to fasten strapping around packages, pallets, and heavy goods. From standard and heavy-duty metal to serrated, wide, plastic, and eco-friendly options, each type is designed to enhance load stability, prevent slippage, and streamline strapping operations in warehouses, logistics, and industrial packaging environments.
-
Standard Lap-Over Metal Seals – Used with PP or PET strapping for general-purpose pallet and carton securing.
-
Heavy-Duty Lap-Over Seals – Thicker metal for high-strength applications, securing heavy loads such as timber, metal coils, or machinery.
-
Zinc-Plated / Coated Lap-Over Seals – Corrosion-resistant for outdoor storage, export shipments, or long-distance transit.
-
Serrated Lap-Over Seals – Internal teeth grip the strapping to prevent slippage, suitable for high-tensile polyester strapping.
-
Eco-Friendly / Recyclable Lap-Over Seals – Designed for use with recyclable strapping for sustainable packaging operations.
Lap Over Strapping Seals: Strong, Secure, and Reliable Load Fastening
Lap over strapping seals are designed to provide a secure and durable closure for polypropylene (PP), polyester (PET), and steel strapping, ensuring pallets, boxes, and heavy loads remain stable during storage and transit. Lap over strapping seals grip tightly over overlapping strapping, delivering tamper-resistant strength that protects shipments from shifting, damage, or loosening during handling and transportation. They are widely used in logistics, warehousing, manufacturing, and industrial shipping to maintain product integrity.
One of the key advantages of lap over strapping seals is their simplicity and effectiveness. Unlike other sealing methods, lap over seals are applied over the overlapping portion of the strapping, providing a reliable hold without complex installation. They can be used with manual, semi-automatic, or automatic strapping tools, offering fast, consistent, and efficient load security for both light-duty and heavy-duty applications.
Sustainability is increasingly important in packaging, and many recyclable lap over strapping seals are available to reduce environmental impact. When paired with eco-friendly PET or PP strapping, these seals help companies achieve strong load protection while supporting responsible packaging practices. By investing in high-quality lap over strapping seals, businesses can improve operational efficiency, ensure safe deliveries, and demonstrate a commitment to environmentally responsible packaging solutions—making them an essential choice for modern shipping and logistics.
