    Protecting what is valuable: Neschen is regarded as the inventor of self-adhesive products for the professional repair and protection of books and documents. We are proud to say that these products are often taken off the shelf or are regularly, eventually take damage. These damages can range from torn or loose pages to damaged book spines. Replacing books can create high additional costs for libraries. Since prevention is always better than repairing the damage, it is a wise decision to protect or strengthen books and papers. This increases durability and saves costs.

    Protecting history | Preservation of Documents

    Besides being used for books, our products are used to repair and protect important documents. Many of the Filmoplast line of products have a special composition that works perfectly with the chemical composition of aged paper and the ageing resistance of several products has been assessed and certified by the Foundation for Paper Technology (PTS) in Munich

    Filmoplast R for example is used in the Political Archive of the Federal Foreign Office in Berlin. The Political Archive is almost like a "memory" of the German Foreign Service. Twentyseven kilometers of shelves containing diplomatic documents since 1871, including 35,000 international treaties and countless personnel records bear witness to history. The material is accessible to everyone within the framework of the legal provisions. In the public reading room with 32 sears, more than 1,000 visitors per year inform themselves about historical contexts.

    The archive also holds its own restoration workshop, in which employees process damaged archive materials. These include 75 meters of shelf space for fire-damaged files from World War II. The experts bring the archive records into a condition that protects them from further decay for as long as possible and that allows them to be worked with.

    Important historical documents, which were partially damaged by fire during World War II, have been sealed with Filmoplast R to preserve them from further damage. Since the mid 1990s, the staff of the restoration workshop have been using Neschen Filmoplast R for their work.

    Filmoplast R is a wafer-thin, transparent, technical Japanese paper for mass conservation. It is also an ideal material for the preservation of modern papers and newspapers (for wood pulp papers, approx. from the middle of the 19th century). Woodpulp papers contain acid (lignin), which attacks the paper from the inside. This valuable documentation of our past will destroy itself. When encapsulated in Filmoplast R the magnesium carbonate in the adhesive neutralizes acids and prevents migration through the adhesive layer into the Filmoplast R paper layer, thus stabilizing the encapsulated document. Due to the low thickness of the material Filmoplast R is hardly visible. The paper character of the original is preserved. Encapsulated book pages can easily be put together again as a book.

    How to clean books that have been wrapped with protection films

    Book protection films have many advantages: In addition to protecting against damage, the book's covers are easy to clean and resistant to a wide range of cleaning agents and solvents.  The easy-to-clean and resistant to a wide range of cleaning agents and solvents.  The easy-to-clean covers are a big advantage for libraries and any other location where books are handled by many people.  Nevertheless, there are a few points you should consider when cleaning your wrapped books.

    Cleaning book protection films

    In order to prevent dust particles, small grains of sand or other particles from damaging the surface, damp cleaning is recommended for book protection films.  A special cleaner for films is not necessary and conventional cleaning agents can be used.  A mixture of warm water and detergent is very effective.  However, very aggressive or abrasive cleaning agents are not suitable.

    Disinfecting book protection films

    How the book protection film can also be disinfected and not just cleaned, depends on the film.

    To select the right kind of disinfectant, take into consideration which types of microorganisms are to be killed.  Additionally, it is important to keep the agent's effect on the material in mind.   Not every surface is compatible with all types of disinfectants.  Under certain circumstances, some book protection films can be damaged by the use of certain chemical compositions.

    To clean book protection films thoroughly, it is wise to disinfect them with a liquid agent.  Disinfection with gases (such as ethylene oxide) and radiation (beta or gamma rays) is not possible with book protection films.

    Liquid disinfectants are based on

    • Ethanol
    • Isopropanol
    • Glycerine
    • Hydrogen Peroxide
    • Distilled Water

    However, these components can have a negative effect on plastic, depending on their concentration, exposure time and temperature.  Additionally, the reaction depends on the plastic material itself because every type of surface reacts differently to these chemicals.

    Disinfecting PVC-based book protection films

    Book protection films made of PVC are sensitive to ethanol and isopropanol. The result: The film becomes brittle if it repeatedly comes into contact with these substances. The two named chemicals dissolve the plasticisers and the alcohol penetrates the film, causing it to swell up. Afterwards, the film will feel sticky. However, Glycerine, hydrogen peroxide and distilled water do not harm PVC films and are therefore a better choice for disinfection.

    Disinfecting PP-based book protection films

    When it comes to disinfecting PP-based films, it is important to know that hydrogen peroxide can damage the surface more easily due to its oxidation effect.The other components (ethanol, isopropanol, glycerine and distilled water) do not harm the material and are a good choice.

    Note: Both, PP and PVC book protection films should be cleaned or disinfected carefully, otherwise the surface will get scratches from the cleaning motion, resulting in the film’s transparency to be lost.

  3. Book Protection: PVC versus Polypropylene films

    Book Protection: PVC versus Polypropylene films

    In many industries, products and manufacturing processes that are more sustainable is becoming more and more important. In the field of self-adhesive media, the movement towards eco-friendliness represents a major challenge. The problem is obvious: Plastic and therefore self-adhesive films are generally challenging in regards to their eco-friendliness. However, it is difficult to avoid them completely in everyday life. For example in book protection films, PVC (polyvinyl chloride) has many advantages towards other materials and is easy to work with. Nevertheless, Neschen has developed many product alternatives on the basis of PP (polypropylene) instead of PVC over the years. This way, customers can choose a suitable product depending on each individual application. Additionally, Neschen works with solvent-free acrylate adhesives and ensures that all raw materials are free of harmful additives.

    But what exactly is the difference between PVC and PP?

    After PE (polyethylene) and PP, PVC is the third most important polymer for plastics. PVC is divided into hard and soft PVC. Many users prefer PVC films because they are softer and more elastic and therefore easier to process. PP is recognised as an eco-friendlier alternative because it is a simply structured synthetic material and also a “by-product” of the petrol industry. This resource is put to good use in the form of protecting or mounting films.

    Over the years, Neschen has developed alternatives on the basis of PP for virtually every application (digital print, protection and mounting films). PP films are a little more difficult to work with because they are less flexible. Cutting through the material is also a little more difficult than cutting through the PVC version.

    Nevertheless, a lot speaks for using PP films as an alternative to PVC:

    • non-toxic combustion
    • byproduct of the petrol industry
    • does not contaminate ground water
    • virtually shrink-proof
    • temperature resistant up to +100°C (212°F)
