Unprinted inkjet-printable fillable pouches and methods for producing and printing said pouches

An unprinted inkjet-printable fillable pouch made of an unprinted inkjet-printable film comprising:

• (a) a multilayer polymer film comprising a base layer (a1) and a sealing layer (a2), which is the inner layer of the pouch;
• and
• (b) at least one ink-receiving layer as the outer layer deposited on the multilayer polymer film (a) from an aqueous coating composition comprising:
• (b1) a polymeric binder;
• (b2) fine inorganic particles having a median particle size (Dv50) of from 50 to 300 nm, as determined by laser diffraction according to ISO 13320:2020-01;
• and
• (b3) coarse inorganic and/or organic particles having a median particle size (Dv50) of from 5 to 14 μm, as determined by laser diffraction according to ISO 13320:2020-01,
• wherein the unprinted inkjet-printable film has an average surface roughness Rz of from 3.0 to 12.0 μm, as determined on the surface of the ink-receiving layer (b) according to DIN EN ISO 4287:2010-07 with a sampling length ln of 4.0 mm and a single sampling length lr of 0.8 mm as defined in DIN EN ISO 4288:1998-04 with a 2 μm probe tip and an aperiodic profile setting.
