Method for operating an apparatus for producing plastic preforms and plastic containers, comprising at least one injection moulding machine and one blow moulding machine, wherein the plastic preforms are injection moulded within the injection moulding machine and are formed into plastic containers within the blow moulding machine and are transported from the injection moulding machine to the blow moulding machine, wherein a heating device is arranged downstream of the injection moulding machine and the injection moulding machine and the blow moulding machine are coupled to one another. According to the invention, the plastic preforms produced in the injection moulding machine are transferred directly after production to a thermal preform storage, which holds the plastic preforms at a predetermined temperature and wherein a speed and/or at least one parameter of at least one subsequent treatment device can be changed.

A method for forming a balloon provides a preform that encloses an internal space. The preform is pre-heated to a shaping temperature by passing a heated gas or fluid via an inlet of the preform into the internal space. The preform is then shaped the preform into a balloon. A device is configured to heat a preform using heated gas or fluid to decouple heating from the temperature of a shaping tool.

A stretch-blow-formed polyester container having an average thickness of not more than 280 μm in the body portion thereof, and effectively suppressing the deformation that is caused when the container is filled with a content of a high temperature, wherein in the measurement of dynamic viscoelastic properties in an axial direction at a central portion of said body portion, a tan δ peak value and a tan δ peak temperature at the peak value satisfy either; (i) the tan δ peak value is in a range of 0.23 to 0.29, and the tan δ peak temperature at the peak value is in a range of 111 to 118° C.δ; or (ii) the tan δ peak value is in a range of less than 0.25, and the tan δ peak temperature at the peak value is in a range of not lower than 119° C.

A manufactured blow-molded log assembly created from a thermo-mold polymer that is shapable using a blow-molding process of inserting an ingot into a blow-molding tool and injecting heated gas into the ingot to substantially shape the ingot into the manufactured log. The log assembly may then be removed from the blow molding tool and painted. The log assembly can include one or more, but preferably, a plurality, of such manufactured logs. The process may be used to create a log assembly that includes multiple manufactured logs, connected together or produced separately and stacked or otherwise arranged to simulate the appearance of real logs, which can be positioned inside an electric fireplace.
