A method for tempering preforms in a blowing machine, wherein at least one heating box is arranged along a transport path for the preforms. The heating box has reflective walls and forms a heating channel through which the preforms are guided. The heating box also has a heater for heating the preforms in the heating channel, and a cooling device, having a blower, for cooling the reflective walls. The walls are cooled by a quantity of air flowing along the walls outside the heating channel. The heating output of the heater is adjustable. A control device provides open loop and closed-loop control of the cooling output produced by the cooling device, in particular the supplied quantity of air, depending on the respective heating output of the heater, depending on a measurement of the heating output.

The present invention relates to an integrally blow-moulded bag-in-container (2) and preform(1, 1) for blow-moulding the bag-in-container. An inner layer (11) and an outer layer (12) are used, wherein the preform forms a two-layer container upon blow-moulding, and wherein the obtained inner layer of said container releases from the thus obtained outer layer upon introduction of a gas at a point of interface (14) between the two layers. At least one of the inner and outer layers includes at least one additive allowing both inner and outer layers to reach their respective blow-moulding temperatures substantially simultaneously.

The invention relates to a method for manufacturing a plastic container, the method comprising the following steps: o providing an injected preform, o heating the preform (S2), and o performing stretch blow molding (S3) of the preform, thereby forming the container. The preform is made of a material comprising 40 to 99.9 weight percent of Polyhydroxyalkanoate (PHA). In the heating step, the preform is brought to a temperature comprised in a range between 1 C. and 20 C. under the melting temperature of the PHA. The present invention thus makes it possible to perform ISBM of Polyhydroxyalkanoate to produce a plastic container.
