Abstract
A blow molded multilayer article with a hollow body and a wall being formed by at least three layers including a first skin layer, a second skin layer and a core sandwiched between the first and second skin layers. The skin layers can include a first thermoplastic material and an effect pigment and/or a porogen. The core can include recycled thermoplastic material and pigment and/or dye. The article can contain greater than 30% recycled thermoplastic material.
Claims19
A blow molded multilayer article comprising:
- a. a hollow body defined by a wall comprising an inner surface and an outer surface, the wall being formed in at least one region by 3 or more layers comprising:
- i. a first skin layer and a second skin layer comprising:
- from about 94% to about 99.5% by weight of the first skin layer and second skin layer of a mechanically recycled thermoplastic material comprising a first thermoplastic material;
- and
- 0.5% to 2% by weight of the first or second skin layers of a dye, pigment, and/or an effect pigment producing a chroma of 15 or greater in the blow molded multilayer article;
- wherein the first skin layer comprises the outer surface of the wall in the region and the second skin layer comprises the inner surface of the wall in the region;
- ii. a core sandwiched between the first skin layer and the second skin layer, wherein the core comprises:
- from about 90% to about 99% mechanically recycled thermoplastic material by weight comprising a second thermoplastic material and greater than 200 ppm impurities wherein the article comprises greater than 92% mechanically recycled thermoplastic material by weight and wherein the mechanically recycled thermoplastic comprises green, brown, gray, black, blue, and/or combinations thereof.
