American Casting and Manufacturing provides a host of airline security seals. These are designed to keep cargo protected during short and long trips alike, in addition to follow protocols implemented by different airlines. Additionally, they serve various aspects of flights, including the securement of food and beverage carts, duty free items, doors without latches, waste containers, and fire extinguishers.
Airline security seals are tamper-evident devices used to secure galley carts, food and beverage trolleys, duty-free compartments, waste containers, fire extinguishers, and cargo bags throughout ground handling and in-flight operations. They provide documented evidence that contents have not been accessed between the point of sealing, typically the catering facility or cargo handler, and the point of inspection or delivery.
The airline line includes adjustable plastic pull-tight seals, plastic padlock seals, writable padlock seals, and tamper-evident labels with and without adhesive residue. Pull-tight and padlock seals are used on cart handles and bin hasps, while tamper-evident labels are applied to surface closures, access panels, and carton flaps. Each type is suited to a different application within the aircraft or ground handling environment.
Tamper-evident labels are flat adhesive products applied directly to surfaces. When removed, they leave a visible residue or void pattern that alerts ground crews to interference. Plastic pull-tight and padlock seals physically secure a loop or hasp and must be cut to remove. Labels are best for trays, panels, and compartment doors, while pull-tight or padlock seals are preferred for cart handles, cargo bags, and bins where a mechanical hasp or loop is present.
Breaking strengths in the airline line range from 3 lbs (1.4 kg) for light-duty meal cart applications up to 70 lbs (31.8 kg) for more secure cargo bins or duty-free carts. For low-security applications like sealed meal trays or small accessory compartments, a lighter seal is appropriate. For duty-free carts or cargo with higher theft risk, a heavier-duty model provides meaningfully more physical resistance.
Labels with residue leave a visible adhesive pattern on the surface when peeled, making tampering immediately apparent even after the label is removed. No-residue labels are designed for sensitive or high-gloss surfaces, such as aircraft interior panels, electronic displays, and premium equipment, where adhesive damage after removal is not acceptable. The right choice depends on the surface material and the airline's cabin cleaning and maintenance procedures.
Yes. Most airline seal models are available barcoded and sequentially numbered. Barcoded seals can be scanned during ground handling operations to create an electronic log of every sealed unit from the catering facility or cargo handler through to the aircraft and back, without manual data entry. This supports both internal accountability programs and compliance with airline or airport authority record-keeping requirements.
Yes. Custom sequential numbering, airline name or logo, and color options are available on most seal models. Many airlines use color coding to organize seals by route, shift, or service type, making it faster for ground handling staff to verify the correct seal is in place during time-sensitive turnarounds. The Writable Padlock Seal also allows staff to add handwritten route or date information directly on the seal body at application.
