PLA (polylactide) polymer 4060D can be coextruded with other PLA resin to form a sealant layer for biaxially oriented PLA film. This resin has excellent heat seal and hot tack performance with a seal initiation temperature of 80ºC. This sealant does not adversely affect the unique properties of NatureWorks® PLA bioriented film such as high gloss and transparency, dead-fold or aroma and grease barrier. |
