A antipilferage seal is a passive device used to detect tampering or entry. A seal is not expected to present a serious obstacle to entry or tampering. The passive nature of seals is indicated in that inspection is required to determine whether entry or tampering has occurred.

Type 1 - In view of the fact that these seals maybe easily counterfeited, they should not be used in applications requiring more than minimal antipilferage security. The crimp/wire seals are also unsuited to harsh or corrosive environments or applications requiring physical strength.

Type 2 - The seals may be utilized in applications requiring moderate antipilferage security. Fold/wire seals are unsuited to harsh or corrosive environments or applications requiring physical strength.

Type 3 - Cup/wire type seals may be utilized with relative assurance in applications requiring moderate antipilferage security. Security personnel should be consulted for modification which may make these seals even more resistant to tampering. Cup/wire seals are unsuited to harsh or corrosive environments.

Type 4 - Wire shackle padlock seals provide relatively low antipilferage security.

Type 5 - Because of the wide variability in tamper resistance between models of plastic padlock seals they should be utilized in applications requiring low strength and minimal antipilferage security.

Type 6 - Steel shackle padlock seals are available which will resist tampering for periods of 2 minutes to in excess of 30 minutes. These should be utilized in applications requiring high strength and high antipilferage security.

Type 7 - The car/box end seal may be easily compromised. This type of seal should be used only for minimal antipilferage security requirements. This seal may be utilized where moderate physical strength is required.

Type 8 - Because of the wide variability in tamper resistance between models of car/plastic seals, they should be used in applications requiring minimal resistance to tampering. Car/plastic seals may be used in applications requiring low physical strength.

Type 9 - Car/ball end seals may be utilized in applications requiring minimal antipilferage security and physical strength.

Type 10 - Crimp type strap seals are standard steel strapping closures with a controlled lithographic design and with special marking used for shipping where more than normal antipilferage security is required.

Type 11 - One piece cable seals should be used in applications requiring high strength and low to moderate resistance to tampering.

Type 12 - Two piece cable seals should be used in applications requiring high strength and low to moderate resistance to tampering.

Types 13 and 14 - Bolt seals may be used in applications requiring high strength and low to moderate antipilferage security.

Type 15 - The plastic tie seal should be used in applications requiring low strength antipilferage security.

Type 16 - The notched metal seal shall be used in applications requiring low strength antipilferage security.

Type 17 - The bendable wire seal shall be used in applications requiring high strength antipilferage security.

Type 18 - The label seal is used in sealing containers by overlapping the container parting line. The surface must be clean and smooth where the seal is applied. Very difficult to compromise but has almost no physical strength.
