Biodegradable and compostable multilayer film

A biodegradable and compostable multilayer film comprising:

• a sealant product side layer:
• comprising at least one slip additive;
• and
• having a pre-determined co-efficient of friction;
• an outer surface layer;
• and
• at least one intermediate layer disposed between said sealant product side layer and said outer surface layer;
• wherein, each of said sealant product side layer, said outer surface layer and said at least one intermediate layer comprises at least one blend independently selected from the group consisting of:
• a first blend of polylactic acid and a copolyester of 1,4-butanediol, adipic acid, and terephthalic acid having a melt temperature in the range of 165° C. to 190° C.;
• a second blend of polylactic acid and a copolyester of 1,4-butanediol, adipic acid, and terephthalic acid having a melt temperature in the range of 190° C. to 200° C.;
• a third blend of polylactic acid and a copolyester of 1,4-butanediol, adipic acid, and terephthalic acid having a melt temperature in the range of 165° C. to 170° C.;
• a fourth blend of polylactic acid and a copolyester of 1,4-butanediol, adipic acid, and terephthalic acid having a melt temperature in the range of 180° C. to 190° C.;
• a fifth blend of polylactic acid and a copolyester of 1,4-butanediol, adipic acid, and terephthalic acid having a melt temperature in the range of 175° C. to 195° C.;
• and
• a sixth blend of polylactic acid and a copolyester of 1,4-butanediol, adipic acid, and terephthalic acid having a melt temperature in the range of 180° C. to 200° C.,
• in a way that said biodegradable and compostable multilayer film comprises at least two layers each having separately at least one of said blends in an amount in the range of 1 wt % to 99 wt %.
