Overview n°3, 09/21/07 - page 4/12


The packagingThe packagingThe packaging field, is a heterogeneous sector that has

different branches. Each branch has unique and critical characteristics. To face these differences, Neophane studies a multiplicity of structures, always keeping in mind the principal functions of a pack:- to contain the product- to protect it from mechanical damage- to assure a suitable barrier to gas and other vapour- to prevent or to delay the degradation of the product- to present and promote the product

The multi-layer materials are produced combining the different properties of each material, in order to optimise cost, performance and machinability.

To make the right choice in terms of materials, it is essential to have a deep understanding of all raw materials involved with the process (not only the film, but also inks and adhesives), as well as that of the final product to be packed, knowledge obtainable only long experience and cooperative partnerships with suppliers and customers.

Overview n°3, 09/21/07 - page 5/12


The different types of filmsThe different types of filmsThe materials normally used for the wrapping of wet wipes and

cosmetics are:

- Polyester - Paper - Alu - Polyethylene

Most of the packaging in common use, are constructed with combinations of these materials-

Polyester: excellent support for printing, thanks to its dimensional stability when heated, it can be considered as the leading film used in this sector, thanks to its good barrier properties and its chemical inertia. Sometimes, it is replaced by co-extruded polypropylene.

Paper: used as printing support, in lamination with other films, it is used for wet wipes single-dose wrapping, as well as for talcum powder and soap tablets (in this case with application of hot-melt adhesives).

Aluminium: used in lamination with plastic films, when the success of the final product is contingent on water vapour and gas resistance.

Polyethylene: used in lamination for its sealing and water vapour barrier properties.

Overview n°3, 09/21/07 - page 6/12


WET WIPESWET WIPESPackaging for the wet wipe sector, is a

significant percentage of Neophane’s sales, in Italy as well as in other European areas.

This is an expanding sector in, as it has well identified some of the conveniences required by the modern life, with more and more diversified products.

Applications:- household- personal care and hygiene- industrial

DUPLEX STRUCTURESDUPLEX STRUCTURESThese structures are composed of two different layers of films and are produced in two phases:1) printing + in-line lamination and 2) slitting

Inks (coverage 100%) – chemical resistance 1 1,00

Adhesive (high performances and chemical resistance) 2 2,60

LDPE SP (also white) 60÷70 55,20÷64,40

PROPERTIES: PROPERTIES: wide sealing range with excellent performance (either in terms of force or hot-tack, as well as in presence of pollutants); high resistance to chemical attack and good barrier to gas and humidity; excellent printability (up to 9 colours). For certain personal care lines, the PET film is substituted by matt BOPP film, giving a soft touch sensation.
