Embodiment Construction

[0023] In order to fully understand the above details and other advantages and objects of the present invention, the present invention will be described in detail below with reference to specific embodiments.

[0024] The present invention provides a formulation for the production of waterproof packaging items such as boxes, containers, plates, plates, bowls, cups, etc., comprising water, starch, optionally an insoluble compound to enhance the moisture resistance of the starch portion of the baked food item Performance, optional protein and natural polymers to reduce the brittleness of packaged items when used in a dry environment and prevent damage when they are just formed in a dry situation, optional several natural fiber materials to be used as Structural reinforcing components of packaging items (in several size ranges) which in turn serve as inexpensive organic alternatives to inorganic fillers, optional wax emulsions and / or fiber sizing for enhanced water resistance, and...

Abstract

This invention relates to a composition for preparing starch-based food or beverage container, the formulation of this composition is used for producing water resistance water during service time without coating or similar processes. Formulation of this composition according to this invention includes water, natural pregelatinized starch, insoluble compound, protein or natural polymer, fiber, waxemulsion and fiber sizing agent.

Description

technical field [0001] The present invention relates to a mixing formulation for producing biodegradable articles, and methods of using said formulation. Background technique [0002] Traditional disposable food containers are generally made of paper or cardboard (usually covered or impregnated with a waterproof polymeric material such as wax or polyethylene) or various plastics (most commonly polystyrene). These materials have excellent moisture resistance, can insulate (Styrofoam), and are cheap and durable. Industrial production methods are well established from these materials for the production of single-use packaging utensils, which can be mass-produced quickly and relatively cheaply. [0003] However, there is growing awareness of the high environmental costs of using such cheap materials. For example, a polystyrene cup may be around for about 500 years, and the average American consumes about 100 such cups per year; moreover, polystyrene is synthesized by a chemica...
