Anti-static materials

Anti-static materials are used to make bags and pouches when there is a need to counteract the damaging effects of static charges on the contents. The material was originally used to protect gun powder which had a propensity to ignite when exposed to static. Nowadays it is more commonly used to shield circuit boards and computer chips. The most common antistatic materials are:

ANTI-STATIC-These bags are normally translucent-pink in colour, principally for identification purposes. They have one layer of film and an anti-static dissipative layer. They discharge static away from the contents but do not shield them. The charge is merely allowed to pass through the bag.

STATIC SHIELDING CONTROL-The semi-translucent colour is achieved through three or four layers of aluminium film. This metalicised bag discharges static and shields the contents. Originally nickel was used in place of aluminium.

CONDUCTIVE-These are normally black in colour with a single layer that is carbon loaded, hence the matt-black finish. The bag shields and discharges the static quickly but can damage the item inside.

STATIC DISSIPATIVE-Clear in colour and comprising a single protective layer these bags are normally identified by a printed symbol or an all-over, cross-hatched printed effect. They have all the properties of a static shielding bag but do not shield the contents from static damage.

Away from the electronics industry the bags have been used for house invitations, CDs and cosmetics to name a few. They are attractive to designers for their allusions to futuristics and industrial themes. They are available as open-topped for vacuum sealing. with a grip-seal closure and also with a peel and seal closure.

Denim

A relation of canvas and not strictly the preserve of clothing. Some suppliers of book-binding cloth will coat the reverse so you can cover and line your packaging. If you want to distress denim use a cheese grater. Sandpaper does not work.

Fake fur

Fake fur is made from anything from nylon and rayon to acrylic. It comes with a wide variety of backing and is supplied in numerous shades, patterns and piles.

Glass

The use of glass in packaging has been overtaken by Perspex, as it is more flexible and cheaper. However, it is an exciting challenge to undertake but care should be taken when gluing as the glue lines will be very visible.
