Silver is a precious material – whether as cutlery, jewellery, silverware or as a silver-plated surface in electronics. But anyone familiar with silver knows the problem: even after a short period of storage or during transport, silver surfaces can tarnish, darken and become unsightly. The cause lies in the air – and so does the solution. Silverbrite is a specially developed silver protection paper from BRANOpac that actively binds corrosive air components and effectively prevents tarnishing and discolouration – for household applications as well as technical and industrial uses.
The key facts about Silverbrite at a glance
- Silverbrite is a bleached kraft paper with an active ingredient coating – specially developed to protect silver and silver-plated surfaces from tarnishing and discolouration.
- The paper actively binds corrosive air components – in particular sulphur-containing compounds – and thereby prevents them from reacting with the silver surface.
- Applied by simple wrapping or lining – for cutlery, jewellery and silverware in the household, as well as for silver-plated components and contacts in industry and electronics.
- Silverbrite is suitable for storage and transport – as temporary corrosion protection that can be easily integrated into existing packaging and logistics processes.
Why does silver tarnish? – Causes and the formation of tarnish
Silver reacts sensitively to certain compounds in the surrounding air. What is perceived in everyday life as an unsightly discolouration or dark layer is chemically a corrosion reaction: sulphur-containing compounds in the air react with the silver surface and form silver sulphide – a dark, matt coating known as "tarnish".
Sulphur compounds as the main cause
Sulphur-containing compounds occur in the ambient air in various forms – for example through industrial emissions, household products, rubber or organic materials. Even low concentrations of these compounds are sufficient to alter silver surfaces over time. Particularly affected are surfaces that are stored or packaged for longer periods without any active temporary corrosion protection in place.
When does tarnishing occur particularly quickly?
The tarnishing of silver accelerates under certain conditions: high humidity, fluctuating temperatures and poor air circulation all promote the reaction. Unsuitable packaging materials can also exacerbate the problem – for example if they have no pollutant-binding effect and cannot retain corrosive air components.
What is Silverbrite? – The silver protection paper in detail
Silverbrite is a bleached kraft paper with a special active ingredient coating, developed specifically to protect silver and silver-plated surfaces from tarnishing and discolouration. It combines the mechanical properties of a robust kraft paper with an active protective function against corrosive air components.
Structure and material
The basis of Silverbrite is a bleached kraft paper – a durable, tear-resistant material that is well suited for wrapping and lining. The key is the active ingredient coating applied to it: this gives the paper its protective function and makes it far more than a simple wrapper.
Mode of action – binding sulphur compounds rather than sealing
Silverbrite does not work by complete sealing, but by active binding: corrosive air components – in particular sulphur-containing compounds – are absorbed by the coating and thereby prevented from reacting with the silver surface. Air exchange takes place through the paper itself, not around it. This creates a protective atmosphere around the packaged object without the need for complete sealing.

Get in touch nowHow is Silverbrite used? – Wrapping, lining, protecting
Silverbrite is straightforward and flexible to use. The paper can be used both for wrapping individual objects and for lining containers such as cutlery cases, drawers or transport packaging.
Wrapping and lining – step by step
When wrapping, the object to be protected is completely enclosed in Silverbrite. Care should be taken to ensure that air exchange takes place exclusively through the paper – loose wrapping is preferable to tightly knotted packaging, as the paper can only develop its effect when air diffuses through it. When lining, the paper is laid flat inside cutlery cases, jewellery boxes or packaging containers so that all surfaces are in direct contact with the protective paper.
Household applications – cutlery, jewellery and silverware
In the household, Silverbrite is particularly suitable for storing silver cutlery, silverware and silver jewellery. Cutlery cases can be lined with the paper, and individual items can be wrapped. This can effectively reduce tarnishing during longer periods of storage – for example between seasonal uses.
Technical applications – silver-plated contacts and components
Silverbrite also demonstrates its strengths in technical and industrial applications: silver-plated electronic contacts, components from electroplating or parts from connector manufacturing can be protected with Silverbrite during storage and transport. In the electronics industry in particular, preserving the surface is critical for functionality – tarnishing or discolouration can impair the conductivity of silver-plated contacts. Silverbrite offers temporary corrosion protection that can be readily integrated into production and logistics processes.
Areas of application – household, industry and electronics
Silverbrite is versatile and addresses a wide range of target groups – from households to industrial users.
Industry – storage and transport of silver-plated components
In industrial storage and the transport of silver-plated components, effective tarnish protection is essential. Silverbrite can be used as an insert in transport packaging or as a wrapping material for individual parts. It is suitable for the protective packaging of precious metal components that are stored for longer periods or exposed to environmental influences during transport.
Household – cutlery cases, jewellery and silverware
For private use, Silverbrite offers a simple and effective way to keep silverware looking its best. Lining cutlery cases with Silverbrite is a classic application: the paper is laid into the compartments and protects spoons, forks and knives made of silver or with silver-plated surfaces from tarnishing. Silver jewellery and coins can also be safely wrapped and stored.
Electronics – protection of silver-plated contacts
In the electronics industry, silver-plated contacts and conductor tracks are frequently stored for extended periods before being processed further in production. Silverbrite is suitable as protective packaging to preserve these surfaces during storage. Tarnishing or discolouration that could impair electrical conductivity can thus be effectively reduced.
Silverbrite binds corrosive air components – in particular sulphur-containing compounds – through its active ingredient coating. Air exchange takes place through the paper, so that harmful components are intercepted before they can react with the silver surface.
Silverbrite protects both pure silver and silver-plated surfaces – including cutlery, jewellery, silverware, silver-plated electronic contacts and components from electroplating.
The objects to be protected are completely wrapped in Silverbrite, or the paper is laid as a lining into containers. Air exchange should take place exclusively through the paper so that the active ingredient coating can fulfil its function.
Ordinary plastic film has no active protective effect against sulphur compounds. It cannot retain air pollutants and therefore offers no comparable protection against tarnishing. Silverbrite, by contrast, actively binds corrosive air components through its coating.
Yes. Silverbrite is expressly suitable for technical applications such as the storage and transport of silver-plated electronic contacts or components. It provides temporary corrosion protection that can be readily integrated into industrial storage and logistics processes.
