Abstract
Embodiments relate to an additive for a biopolymer article, a method for forming the additive and biopolymer articles and sheeting containing or formed using the additive. The additive includes at least one impact modifier between 10-90 weight % of the total weight of the additive; at least one polymer color concentrate between 5-50 weight % of the total weight of the additive; and at least one carrier resin between 5-50 weight % of the total weight of the additive.
Claims36
An additive for a biopolymer article comprising:
- at least one impact modifier between 10-90 weight % of the total weight of the additive;
- and
- at least one pigment/dye compounded in a carrier resin, where the carrier resin is between 10-90 weight % of the total weight of the additive.
A pellet comprising:
- at least one impact modifier between 10-90 weight % of the total weight of the pellet;
- at least one polymer color concentrate between 5-50 weight % of the total weight of the pellet;
- and
- at least one carrier resin between 5-50 weight % of the total weight of the pellet.
A method of forming an additive comprising:
- providing at least one impact modifier, at least one polymer color concentrate and at least one carrier resin;
- blending the at least one impact modifier, the at least one polymer color concentrate and the at least one carrier resin forming an additive blend, wherein the at least one impact modifier is between 10-90 weight % of the total weight of the additive blend, the at least one polymer color concentrate is between 5-50 weight % of the total weight of the additive blend and the at least one carrier resin is between 5-50 weight % of the total weight of the additive blend;
- and
- molding the additive blend.
A biopolymer article comprising:
- at least one biopolymer resin between 75-92 weight % of the total weight percent of the biopolymer article;
- and
- an additive between 8-25 weight % of the total weight percent of the biopolymer article, the additive comprising:
- at least one impact modifier between 10-90 weight % of the total weight of the additive;
- at least one polymer color concentrate between 5-50 weight % of the total weight of the additive;
- and
- at least one carrier resin between 5-50 weight % of the total weight of the additive, whereby the biopolymer article has a predetermined thickness and impact resistance.
A biopolymer extruded sheeting comprising:
- at least one biopolymer resin between 70-92 weight % of the total weight of the extruded sheet;
- and an additive between 8-30 weight % of the total weight of the sheeting;
- the additive containing;
- at least one impact modifier between 10-90 weight % of the total weight of the additive;
- at least one polymer color concentrate between 5-50 weight % of the total weight of the additive;
- and
- at least one carrier resin between 5-50 weight % of the total weight of the additive.
- whereby the extruded sheet has a predetermined thickness and impact resistance.
