Abstract

This concerns a thermoadhesive multi-layer film suitable for computerized cutting or else for design/printing and subsequent cutting, to obtain portions from it to be applied onto fabrics and the like. It is characterized by the following four layers: A) first support ‘carrier’ made from paper or polyester plastic film, made suitably sticky or alternatively treated, with per se known methods, with a process suitable for giving it particular roughness; B) second support ‘carrier’, made from paper or polythene plastic film; C)colored film with one or more polymer-based layers, able to ‘float’ on the support without sinking during the application of the writing to the support itself; D) thermo-softening film, also with one or more polymer-based layers, intended to melt onto the destination material, fixing the decoration to the aforementioned support.

Claims

1. THERMOADHESIVE MULTI-LAYER FILM, comprising the following four layers:

A) first support “

carrier”

made from paper or polyester plastic film;

B) second support “

carrier”

, made from paper or polythene plastic film;

C) colored film with one or more polymer-based layers;

D) thermo-softening film, also with one or more polymer-based layers, intended to melt onto the destination material, fixing the decoration to the aforementioned support.

2. FILM, according to claim 1, wherein layer C consists of a colored film that foresees one or more polymer-based layers, foreseen in a percentage of more than 50%, kofler/hot melting point (ANSI/ASTM 03451-76)>

1600, which is able to “

float”

on the material without sinking during the application of the decoration to the aforementioned material, such a film also being able to deform mechanically both longitudinally and transversally.

3. FILM, according to claim 2, wherein layer C consists of a base of polymers, selected from the group comprising acrylic resins, polyurethane resins (PU), copolyester resins (TPE-E) , co-polyamide resins (TPE-PA) and/or their mixtures.

4. FILM, according to claim 2, wherein layer D consists of a thermo-softening film, in turn also made from one or more layers of thermoplastic polymers (foreseen in a percentage of more than 50%), with kofler/hot melting point (ANSI/ASTN D3451-76)<

1400, such a film being able to mechanically deform both longitudinally and transversally.

5. FILM, according to claim 1, wherein the combination of the two layers C and D is obtained through co-extrusion in flat or blown film, through spreading, through calendering or through lamination of many films.

6. FILM, according to claim 1, wherein at least one of the two layers C and D consists of a base of polymers, with a percentage of more than 50%, selected from the group comprising acrylic resins, polyurethane resins (PU), co-polyester resins (TPE-E), co-polyamide resins (TPE-PA) and/or their mixtures.
