Abstract
Disclosed herein is a multi-layered matte film comprising at last one layer of a coating comprising the condensation reaction product of the combination of a polyalkylimine and an acetoacetonate (“AcAc”)-functional material or an oxirane-functional material, each comprising an ethenic unsaturation group, the coating adhered to a sealant film layer; a sealant layer comprising a polyolefin and having a Tm within the range of from 120° C. to 170° C.; and a Flexural Modulus within the range from 500 to 1200 MPa; a core polypropylene layer; and a matte layer between the sealant layer and core layer, the matte layer comprising a blend of at least two incompatible polymers such that the Haze is at least 50%.
Claims24
A multi-layered matte film, having a first side and second side, comprising a coating on at least the first side, wherein the coating comprises a condensation product of a polyalkylimine and one or more amine-reactive molecules comprising at least one of:
- Rc═C(Ra)—(CX2)j—C(O)—(CX2)k—(O—[CRd2]q)p-A-C(O)—C(Rb)═CX2
- or
- Y—(CX2)m—(O—[CRd2]q)p-A-C(O)—C(Rb)═CX2
- where Y is halogen or a three-membered oxirane ring;
- Ra and Rb are the same or different and are H or a C1 to C6 to alkyl;
- Rc is oxygen or CX2;
- each X can be the same or different and is H, hydroxyl, halogen, or any organic radical containing at least one carbon atom, wherein each Rd can be the same or different and are H or a C1 to C6 to alkyl;
- A is oxygen or NRd;
- CRd and CRd2 can each be a separate moiety or a portion of a cyclic structure;
- j, k, and m are integers ranging from 0 to 6, inclusive;
- q is an integer ranging from 1 to 6, inclusive;
- and p is an integer ranging from 0 to 30, inclusive;
- and
- a primer layer between the first side of the multi-layered matte film and the coating, the primer layer comprising a polyalkylamine having a weight average molecular weight of from 20,000 g/mol to 500,000 g/mol,
- wherein the multi-layer matte film further comprises at least a core layer of polypropylene, a sealant layer and a matte layer between the sealant layer and core layer.
A multi-layered matte film comprising:
- at last one layer of a coating comprising the condensation product of a combination of a polyalkylimine and an acetoacetonate (“AcAc”)-functional material or an oxirane-functional material, the acetoacetonate and oxirane-functional materials comprising an ethenic unsaturation group, the coating adhered to a sealant layer;
- the sealant layer comprising a polyolefin, having a Tm within a range of from 120° C. to 170° C.;
- and a melt flow rate (ASTM 1238, 2.16 kg/230° C.) within a range of from 3 g/10 min to 20 g/10 min;
- and an elongation (ASTM D638) within a range of from 500% to 1200%;
- and a density of from 0.85 g/cm3 to 0.94 g/cm3 (ASTM D792);
- and a tensile strength at break (ASTM D638) within a range from 30 MPa to 60 MPa;
- and a Flexural Modulus (ASTM D790) within a range from 500 MPa to 1200 MPa;
- a primer layer applied between the sealant layer and the coating, the primer layer comprising a polyalkylamine having a weight average molecular weight of from 20,000 g/mol to 500,000 g/mol;
- a core polypropylene layer;
- and
- a matte layer between the sealant layer and the core polypropylene layer, the matte layer comprising a blend of at least two incompatable polymers such that a Haze (ASTM D1003) is at least 50% or 60% or 70% or 80%.
