These are films for lamination unaltered onto other substrates (plain lamination) or for printing with graphics of any kind and complexity which are then laminated onto other substrates (printed lamination).
For flexible food packaging the gauge used in the market is typically 12µm, with variations of 8, 9, 10, up to 50µm.
In industrial laminates the most commonly used gauges are 12µm, 19µm and 23µm, 36µm, 50µm and 75µm, the latter for more specific industrial applications.
Gauges of up to 350µm are typical of the industrial sector, ranging from laminated products for thermal or electric insulation, up to specialist applications for industries such as solar energy or plastifications.
The range of gauge of the aluminium foil typically used varies substantially according to the sector for which the finished product is intended. The food or pharmaceutical flexible packaging sector uses gauges between 5µm and 45µm for multi-layer structures, while the industrial sector requires gauges between 9µm and 75µm. Naturally, quite a number of the more specialty applications are not included in what is meant to be only a brief overview; Finfoil is, however, happy to answer any further questions you may have.
The films in question are intended to be used in unaltered combination with other media. The gauge varies in relation to the final gauge requested by the client after lamination.
Sealing, and also peelable, layers work on:
We also provide films for hot lamination to PS and APETused to prevent penetration by oxygen of trays and containers. This kind of film is known in the market as "liner".
