Abstract:
1. A flexible laminate material, comprising an inner polymer layer, a barrier layer, and an outer polymer layer, wherein the outer polymer layer comprises starch; and wherein: a. the inner layer is a linear low density polyethylene (LLDPE); b. the laminate material optionally has a layer of resin film which is selected from the group consisting of (i) a low density polyethylene (LDPE), (ii) low density polyethylene blended with modified starch and (iii) a triple layer comprising a layer comprising (1) low density polyethylene optionally blended with modified starch, a layer comprising (2) thermoplastic starch and a layer comprising (3) low density polyethylene optionally blended with modified starch c. the laminate material optionally has a tie layer comprising an ethylene acid copolymer between the optional layer of resin film or the inner layer and the barrier layer; d. the barrier layer is selected from the group consisting of: e. the laminate material optionally has a tie layer comprising an ethylene acid copolymer between the barrier layer and the outer polymer layer; f. the outer polymer layer is selected from the group consisting of (i) low density polyethylene blended with modified starch and (ii) a plastic film comprising one or more layers of low density polyethylene blended with modified starch and one or more layers of low density polyethylene, wherein the starch content of the polyethylene blended with modified starch is 50%-70% by weight based on the weight of the polyethylene blended with modified starch; and the laminate material optionally has an outer label layer.
