Fine Shrink Film Type FX (cross-linked)

Our food safe Castelli polyolefin fine shrink film FX is the universal packaging solution for high demands.

Our fine shrink films are manufactured as 5-layer coex shrink films. Due to this 5-layer cross-linking and the electronic cross-linking, the film is extremely puncture-resistant, which is why smaller film thicknesses can be used for your product. The Castelli film fine shrink film type FX can be processed on all common film sealing machines and shrinking machines. It is extremely thin, good gliding, highly transparent, recyclable and therefore environmentally friendly. As an option, pre-perforation of the film is also possible.

Our FX fine shrink film is ideal for high cycle applications. Even at low temperatures, it adapts perfectly to any product shape and protects reliably against damage and external influences due to its high tear strength and tear-resistant sealing seams. It is therefore also suitable for packaging sharp-edged products. The Castelli FX film is the perfect film type for fully automatic film sealing machines with inline product feed or for products that can only be treated with low heat input due to its good sliding properties.
