Abstract: Single or multiple colorants are infused into a thermoplastic material during melt processing to form preforms and plastic containers exhibiting a marbleized or swirl-type pattern. A base resin and colorant may be fed into an extruder having an extrusion screw (10) and/ or barrel (18) modified in a manner to cause incomplete and non-uniform mixing. The modifications may include notches (14) in some of the flights along the extrusion screw, a reduction in the depth or omission of some of the flights, a reduction in diameter of the extrusion screw, or the provision of a marbleizing torpedo (32) near the discharge nozzle (24). Other techniques include introducing the colorant into vents present along the barrel, using a barrier screw to keep the components separate along the length of the barrel, using a high pressure pump for introducing the colorant near the discharge nozzle, or using multi-material co- injection techniques for co-injecting the base resin and colorant.

Abstract: A multilayer container having enhanced gas barrier properties comprises at least two outer layers comprising a polymer matrix, and at least one barrier layer disposed between the at least two outer layers. The at least one barrier layer comprises a first polymer composition comprising a polymer matrix and a low molecular weight additive. In a particular embodiment, the low molecular weight additive comprises a purine derivative, such as caffeine, and is present in the multilayer container in an amount in the range of about 0.2 to about 10 weight percent of the container.
