Flat plastic seals

Choose based on where it will be used, the required length, and whether you need tamper evidence. Common options include 40 cm seals in packs of 100 made from PP plastic for disposable use on vans, trucks, containers, rail cars, and trailers; some models also come with non-repeating numbers for traceability. If you manage multiple shipments, look for customization options such as color, marking, and size to differentiate loads or customers. For quick visual checks, color variants (blue, yellow, or combinations) help you spot opened seals at a glance. Align the seal choice with the locking method you use and the kinds of surfaces you seal.

Tamper-proof seals are designed to show if a closure has been opened, so you can tell whether a container or asset was accessed. Some options are described as completely tamper proof and support color, marking, and size customization, which lets you assign a unique color or label to each load and tailor the seal to your hasp size. Additionally, a non-repeating number per seal enhances traceability across shipments, making it easier to verify integrity during audits or deliveries.

Fleet operators handling many vehicles have different needs from small storage setups. For a fleet, opt for uniform 40 cm, 100-piece packs that are tamper‑evident and traceable with non-repeating numbers so every seal matches a particular shipment or asset. In contrast, a small storage setup benefits from color or marking customization to differentiate loads or locations, and it may prefer seals with flexible color options or size adjustments to fit various hasps or boxes.

Inspect seals before sealing and after opening to confirm integrity, and discard any with cracks or deformities. Use them on compatible hasps and surfaces, avoiding high heat or direct sunlight to prevent material weakening. Store unopened packs in a cool, dry place to preserve the PP plastic's strength, and replace any damaged seals immediately to maintain security and traceability. Maintain an audit trail by noting each seal's number and date of use in your records.

Colors and sizes are designed to boost organization and quick verification. You will see blue, yellow, and blue-yellow options, with some seals supporting color, marking, and size customization for easy differentiation across shipments. Length options commonly include 40 cm for bulk packs (100 pieces) and 30 cm variants, giving you flexibility to fit different hasps or containers. Using color coding helps supervisors spot tampered seals at a glance, while customized markings can reference customer, date, or route details.

Expect bulk packs of 100 seals in several length options. The most common setup features 40 cm long seals in 100-piece packs, suitable for vans, trucks, and containers. Alternative lengths exist, such as 30 cm seals offered in tamper-proof variants, providing a shorter option for smaller compartments or lighter loads. Across these options, you’ll typically find seals made from PP plastic with disposable ties, and many models enable color or marking customization to align with your workflow.
