Benefits of technology
The patent text describes a method for making a plastic article by blending two different resins and using a special process called co-injection molding. This process allows for recycling and reuse of the plastic, reducing the need for disposal. The "technical effect" of this invention is to provide a more environmentally friendly and cost-effective way to make plastic articles.
Problems solved by technology
Unfortunately, because of its material structure, it is believed to require centuries to fully decompose.
Unfortunately, the caustic wash solution can only remove impurities or additives that are soluble or dispersible in (alkaline) aqueous solution.
In many cases, these additives are not easily recyclable and may complicate and / or prohibit proper recycling of the plastic material.

Abstract
A multilayer thermoplastic article blended with hydrolytically unstable polymers and a material component for improved recyclability. The multilayer thermoplastic article having an inner layer being made of a thermoplastic material, an outer layer being made of a thermoplastic material, and an intermediate layer disposed between the inner layer and the outer layer. The intermediate layer is made of a blended material comprising 50 to 99 wt. % of a hydrolytically unstable polymer and 1 to 50 wt. % of the material component selected from the group consisting of an oxygen scavenger, an oxidizable organic polymer, a passive barrier material, Iron, Ascorbic Acid, and potassium sulfite.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of International Application No. PCT / US2018 / 029948, filed Apr. 27, 2018. The entire disclosure is incorporated herein by reference.FIELD[0002]The present disclosure relates to multilayer thermoplastic articles with improved recyclability and, more particularly, relates to multilayer thermoplastic articles blended with hydrolytically unstable gas barrier polymers and a material component for improved recyclability.BACKGROUND AND SUMMARY[0003]This section provides background information related to the present disclosure which is not necessarily prior art. This section also provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.[0004]Plastic is a popular building material of modern human culture, which is used in a wide variety of applications and products. Because of its ubiquitous nature, plastic was typically used and discarded into la...
