               Biotec seeks Patent Disposal and GREENSEAL Update



Stanelco, the RF (radio frequency) applications group, has undertaken a full
review of its Biotec Holdings GmbH ('Biotec') patent portfolio, following its
joint acquisition with SP Metal of the Biotec business on 5th September 2005.



As part of this review it has identified two specific patents that are not core
to the future direction of the Biotec business under its new ownership. The two
patents, one granted (application EP0861036-A1) and one pending (EP1567025-A),
both apply to biodegradable starch-based cigarette filters. Although Stanelco
and SP Metal believe these patents may represent an immense opportunity of
considerable value to the tobacco industry, they agree that they are not part of
their future business plans for Biotec.



As a result Stanelco plans to divest of the patents and the directly related
intellectual property (IP) that has been developed.



Potential buyers of the relevant patents and related IP are now being actively
sought. Stanelco will announce further details of the disposal process in due
course.



The adoption of Stanelco's GREENSEAL Technology under the ASDA contract
continues to progress in line with expectations, with a number of machines due
to enter commercial operation in the coming weeks. Major steps are also being
made in both Europe and North America towards the commercialisation of a number
of projects, particularly those involving Biotec's materials and Stanelco
intends to update the market with these developments shortly.

About Stanelco plc



The Stanelco Group of companies (the Group) has brought together expertise in
radio frequency (RF) technology, RF applications and biodegradable material
sciences to create a revolutionary range of packaging technologies.



Stanelco's philosophy is that new products and processes must offer solutions
and applications which:



•         give higher added value,

•         are greener, more environmentally sustainable than those they replace

•         and have protectable intellectual property rights.



Stanelco will develop the products and processes to a demonstration stage and
then work with partners in order to reach the markets; and under these
circumstances Stanelco will usually seek to license its technology. Stanelco
invests considerable time and resources in ensuring its technologies are
protected via layers of patents wherever possible.



In this way Stanelco believes it can minimise commercial risk and preserve the
highest value for shareholders.



The products offering the prospect of near term revenue generation are being
given priority over the Group's resources.



Stanelco was founded in 1953 and is a world leader in the development of radio
frequency technologies for processing polymers for edible and packaging
applications and the design and manufacture of optical fibre technology,
induction heating and dielectric welding equipment.  Stanelco's Current
developments include GREENSEAL Food tray lidding technology, STARPOL (starch /
pva blended material), FrogPack high impact low cost packaging format,
CradleWrap range of biodegradable air cushion packaging, Soluble tape, 100%

water-soluble detergent capsules, edible sachets and waste packing.
