We have potential new business using Pet jars to package food we produce.  I'm freaking out a bit as I have no experience with this type of container.  

So far a search for food safety related information is all from a consumers point of view with leaching chemicals.

What I need to know is what control(s) do we put in place to prevent physical contamination.

Is PET production pretty safe to where we don't have to worry about pieces inside the jars?

This project is not big enough yet to expect specialized equipment on the packaging end.

So then is a simple manual upending of each jar enough? Do we use compressed air?  

And then more on the quality than food safety side what kind of defect rate should we expect on lids fitting atop jars?

Thanks for any advice

On matters Food safety, If you have a supplier program it will be pretty easy for you since you just have to follow it. Come up with the specs that you want the jars to match and tell the supplier to meet those. Ask them for a Letter of continuing guarantee which will bind them to always delivering as per the set specs, also ensure each batch is accompanied by a COA which matches the specs. Ask for an MSDS, from this you will be able to tell the specific components inputted into the production of the bottles. Request for migration test results from the supplier from a credible lab. You can download EC 1935/2004 and read on food contact surfaces compliance. 


While receiving, make sure you do some analysis for physical conformity in terms of the defects and foreign matter, also check on packaging integrity, have a tolerance limit for the amount of defective jars allowable into the process line. Agree with the supplier on this first.
