Kenplas Forum ==> Blow Molding (Machine) ==> Different moleculair structure fresh/old PET?

Dear,

I am not in the process, of producing PET products, but have to work with freshly blown PET bottles. A problem I am encountering from time to time, is the stickyness of freshly blown PET bottles.
If these products are left alone for several hours, the stickyness becomes much less. Is there some sort of aging process going on in freshly blown PET?
Can this aging process be altered by changing blow molding settings (temperature, pressure)?
Is there an other way, to overcome this stickyness?
Can this stickyness be measured in some sort of way?
Can anyone provide a drawing, with the arrangement, of the molecules, or meleculair chains of freshly blown PET?

Thank you in advance.

Best regards,

Mark Peperkamp
