Materials and types of marking

The key benefit of Cold weather Polypropylene (PP) is its ability to retain the same impact resistance at low temperatures as it does at less extreme temperatures. This allows this material to be used for seals being used to secure goods in cold storage or extreme environments and still deliver great security value. This material is also FDA approved for securing food items allowing security against tampering and contamination.

Nylon is a strong material that provides great resistance against a wide range of adverse conditions, such as corrosive chemicals, weather effects, heat damage, oil and solvents. This material is also highly impact and wear resistant making it a good alternative for more heavy-duty applications that require a plastic seal.

The main advantage of Polypropylene (PP) Glass Fibre is the low cost to high tensile strength, high chemical resistance, and insulating properties ratio. This makes this material a popular choice for many plastic seals.

ABS has a low melting point allowing this material to be easily used for injection moulding over seals locking mechanisms. ABS also has a high tensile strength and is extremely resistant to physical impacts, in addition to corrosion resistance. Another benefit this material offers to the security seals market is its ability to clearly discolour after any attempt to manipulate the seal. Meaning the finished plastic once applied offers high strength for rough uses, resistance to environmental conditions and high tamper evidence making ABS ideal for the seal’s sector.

Zinc is a common material used in a lot of our seals because it offers a great strength. In addition to excellent corrosion and oxidisation resistance that sets this material apart from iron and steel. This allows our seals to provide high security value for a wide range of uses, even for longer haul applications that will be exposed to various environmental conditions.
