Senkosam Posted September 7, 2011 Report Share Posted September 7, 2011 In NY we've have an unusually wet August and Sept. so the humidity is high in my basement. I've noticed the problem of surface bubbles regardless of the plastic I'm heating or reheating and moreso with old plastic that contains salt. I grind my salt in a coffee grinder which helps reduce large granual plastic sweating as it sits on the shelf, but one thing that has helped the most is sealing all old plastic in zip lock bags with the air force out or in sealed plastic containers. Whatever foaming or bubbling happens initially is easily scrapped away with a steel butter knife, stirred and heated a bit more and then poured with no bubbles. I've been using soft and medium LC , M-F and Chemionics, salted and unsalted and they all have the problem of frothing which wasn't a problem in winter. Nuking may add to the bubbles but again, not a major issue if the plastic is stored properly and stirred. Frank Quote Link to comment Share on other sites More sharing options...
Kajan Posted September 7, 2011 Report Share Posted September 7, 2011 We always have humidity here, just so you know, ziplock bags will stop water from entering, but moisture will go thru the PP ziplock bags. Not sure if thats what your problem is, but just to let you know. Quote Link to comment Share on other sites More sharing options...
