摘要:
A film formed from biopolymer lamination for thermal lamination to a rigid biopolymer structure including a polymer layer; a biopolymer layer; and an adhesive layer joining the polymer layer to the biopolymer layer. The biopolymer layer is thermally adherable to the rigid biopolymer structure.
摘要:
A biopolymer blown film extrusion system comprising an extruder receiving polymer pellets and at least two additives, and generating a molten mass having at least one layer; a die receiving the molten extrudates and generating a bubble having at least one layer from a die orifice; an internal bubble blower operably connected to maintain air inside the bubble; a bubble collapsing frame receiving the bubble and generating a biopolymer film having at least one layer, the film having a selected elongation at break of 180% or more in one direction and heat sealing at 195° F. or less; a nip roller operably connected to draw the biopolymer film from the bubble collapsing frame; a turning bar operably connected to change a travel angle of the biopolymer film; and a travel roller operably connected to direct travel of the biopolymer film.

摘要:
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.
摘要:
A system and method for forming a biopolymer roll stock for a biopolymer form-fill-sealed package, the biopolymer roll stock includes at least one biopolymer resin; and at least one additive, the additive including at least one impact modifier between 5-50 weight % of the total weight of the additive; and at least one polymer color concentrate between 5-50 weight % of the total weight of the additive, whereby the biopolymer roll stock has a predetermined thickness and impact resistance.
