PLA products MUST be stored away from heat sources and in a temperature-controlled environment. PLA has a temperature threshold of 110 degrees (F), which means it can melt before your food even comes into contact with it if it isn’t stored properly.
The main culprits for PLA items melting and warping are:
- Cases or sleeves being exposed to direct sunlight (i.e. left outside, not being stored immediately following delivery, etc.)
- Cases or sleeves not being stored in a temperature controlled environment (i.e. in a hot kitchen, non air-conditioned pantry/storage space, hot food truck, etc.)
Take steps as soon as your products are delivered to make sure your PLA products are stored properly, to avoid problems with melting and warping.
