Low Friction ISBM Bottles
Disclosed is an injection stretch blow molded (ISBM) container containing a surface having a static coefficient of friction (COF) of 0.15 to 0.21, a dynamic COF of 0.06 to 0.1, wherein the surface retains a water contact angle of 76° or higher for up to three minutes after wetting of the surface with a water drop of 14 to 16 mm diameter and the container is made with a polymeric composition containing a high density polyethylene (HDPE) having a dispersity (Mw/Mn) of 9 or higher as measured by GPC; a MI2 of 1 g/10 min or higher as measured by ASTM D-1238; 190° C./2.16 kg, as measured by ASTM D-1238; and an environmental stress crack resistance (ESCR) at 100% Igepal of >150 hours as measured by ASTM D-1693, B.
Preform and bottle
Provided is a method for manufacturing a preform (1). The method includes injecting into a cavity of a mold through the gate: (i) a first colored resin (R1) for a first predetermined time period, and (ii) a second colored resin (R2), having a color different from that of the first colored resin, for a second predetermined time period.

Method for manufacturing a polyester based polymer article
A method of the selection, modification of existing, and/or creation of polyester based polymer materials, which provide improved response to the application of local shear and/or extensional deformation inside the polyester based polymer melt in injection stretch blow molding, is disclosed. A method for manufacturing a polymer article is also provided including injecting a molten polyester based polymer in a preform mold for converting it in a preform while applying shear and/or extensional deformation on the polyester based polymer melt. Applying shear and/or extensional deformation on the polyester based polymer melt includes modifying the flow path of the molten polymer as a function of local pressure profile over at least part of the flow path. The local pressure profile is determined as a function of optimized response of the polyester based polymer melt to the applied local shear and/or extensional deformation over at least said part of the flow path.

LIGHTWEIGHT PLASTIC CONTAINER AND PREFORM
A plastic container includes a hollow body portion including a lower supporting base portion; a sidewall portion extending upwardly from the base portion; and a neck portion extending upwardly from the sidewall portion. The neck portion includes a support flange having an upper and lower surface, at least one thread, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. A preform and method for making a container are also disclosed.
INDUCTIVELY HEATED MOLD SYSTEM
An inductively heated mold system enables rapid heating of the mold and rapid cooling to reduce thermal cycling times by employing an inductive coil in a heater module that inductively heats a ferromagnetic layer configured on the mold body, such as around the outside perimeter of the mold body. A cooling channel may be configured between the inductive coil and the ferromagnetic layer on the mold body to allow a fluid to be passed between the mold body and the heater module to rapidly cool the mold body for removal of the molded part. A plurality of heater modules may be employed that can be coupled together such that the cooling fluid passes through the coupled cooling channels from one module to a second module. In this way heater modules can be combined to provide an inductively heated mold system for a variety of mold body sizes, or lengths.
