Evolution
1th Generation The first-generation security seals were made of wax, clay or resin, melted into a paste stage through heat (with wax) and moisture (with clay). It was then poured over sealing string and relief-stamped. Violators tampered the system by using heat or steam to open the packages.
2th Generation The second generation seals were manufactured in soft metals, such as lead and tin, which were marked and sealed with a plier. Because of the softness in the metal, violators would open the seal and reconstruct it without leaving traces of tampering.
3th Generation The third generation brought two major innovations; the manufacturing of self-locking plain seals and the individual hot-stamped number identification performed afterwards. However, a violator may replace that seal by forging a duplicate from a non-numbered seal, or even alter the numbers on another seal to come up with a duplicate number.
4th Generation ELC has introduced the fourth generation with a brand new concept: 100 % tamper evident plastic seals with high-relief numbering molded during the manufacturing process. Each seal has a unique alphanumeric combination, as human being have their unique finger prints. There is no way to replace that seal for another one with the same identity.
The system is completed with the authentifier, which makes the transcription of the seals serial number onto the manifest document. There is NO transcription errors.
Authentifier 5th Generation In order to keep up with technology, ELC came up with a contemporary numbering system called “In Mold Label” (IML). Bar-codes, numbers, and corporate logo are laser printed on paper, which is applied on the seals tab during the manufacturing process. Paper is fused on the seal and unable to be removed due to its protection bars. State-of-the-art bar codes with check digit provide consistent and dependable readability by eliminating transcription errors and maximizing identification. Exclusive to ELC, the high technology involved in the manufacturing process makes the IML numbering system 100% tamper evident, and 100% modern.
6th Generation The Sixth Generation Seal The need to control and keep track of the several steps of the sealing operation led to the coming of the 6th Generation Seal, a new generation/classification research and developed by ELC Security Products. This is the so-called Virtual Seal or Security Link, in which the tracking of the seal through the web, based on the number/code of the seal, is fully controlled, from the manufacturing phase up to the interpretation of the inspected seals and the seal thrown-out. Please access www.elodeseguranca.com.br for better information about the qualities of the Virtual Seal or Security Link.
The Evolution of Security Envelopes
Security Level 1 Only in the 1970´s there came the first versions of plastic disposable envelopes, aiming at a minimum tamper-proof level, thanks to the employ of the "hot-melt" adhesive. According to the present standards, this type of envelope may be classified as Security Level 1, since they may be opened by accident, under conditions of extreme cold or heat, as well as by tampering with freon.
Security Level 2 and 3

The next evolution brought an envelope provided with an anti-tampering adhesive called Red Void, followed by the Green Void, Security Levels 2 and 3, respectively. It happens, however, that they also may be opened by accident at extreme temperatures, as well as violated through application of freon.
Security Level 5
Then ELC launched in 2005 the Pentalock Envelope, provided with two Void adhesives, to make easier an eventual tampering identification. However, its performance in extreme temperatures has the same limitations of the previous bags.
Security Level 8

The highest standard in Security plastic Envelopes has been reached since the 1980´s with ELC Starlock, up to now an unsurpassed tamper-indicative closure system, made in polyethylene, freon-proof and temperature-proof, with no adhesives to compromise security and recyclability. Be it mentioned, also, the Starlock Plus reusable version, closed with a low-cost disposable seal.
The Evolution of Security Bags
Strongboxes and safes
In the past, traditional safes, wooden-made or including metallic elements, did not provide any indication of an eventual tampering.
Leather or canvas bags, with padlock
The Post-coaches adopted leather or canvas bags, closed with padlock, which did not provide an anti-tampering control
Bags closed with Security Seals
In the 1970´s, the canvas bags of the Brazilian Postal Service came to be closed with the ELC label-holder called Leverlock, later internationally awarded and still in current use in the bags of armored-car companies. The Leverlock is closed with a bar-coded/ check digit numbered seal, allowing a perfect control of the operation. At the beginning of the 1980´s the Brazilian Postal Service moved from the padlock in use in the canvas bags to the ELC Security plastic Seal, which provided an anti-tampering control in bag transportation.
The next evolution, also presented by ELC, was the reusable Snapseal Bag, conceived for document and valuables transportation, but also used in anti-doping kits. Due to its features, the Snapseal Bag is appointed as the highest security level in transportation bags
ELC as an inventive company As referred above, ELC lived intensively all the technological evolution of the Tampering-indicative Devices. Yet, it would be unforgivable not to mention, though very briefly, its position as an inventive company. A very few companies in Brazil may be pointed out as living chiefly from what themselves invent, manufacture and commercialize. This is the case of ELC, today with 140 patents, in Brazil and in countries of the First World, employing 500 people, with distribution companies in Miami and Rome, internationally recognized as a leading company in the market of security seals, bags and envelopes. The small company which commercializes its own single invention is a well-known presence, but when we come to the middle-size company or to the ones with more than 40 years in existence that only operate with products developed by themselves, it is hard to find out a situation comparable with ELC´s.
