Dear All,

 

Can someone advise me on the recommended expiry date for pet resin preforms. My organization manufactures pet resin preforms for blowing into pet bottles and we need to establish the expiry date as per one of our client requirements.

 

Regards,

 

Maurice.

Hi Maurice,

 

From my previous company our supplier declares a 6 month shelf life on the pet preforms before they become unstable to blow into bottles. These are of course based on the moisture content of the preforms post manufacture (the higher the moisture content, the unstable it becomes?) I suggest you doing your own studies to moisture levels to determine the shelf-life of as it will vary from country to country.

 

Cheers,

Ace
