Steve Sterling had an interesting feature in the June issue of Packaging World focused on the use of Earthfirst PLA used to make the bag packaging for fresh baby spinach from Popeye.
The piece is the latest in Sterling's regular contributions focused on sustainability.
The development of the Earthfirst PLA film for fresh food packaging has taken a significant amount of effort by Plastic Suppliers makers of Earthfirst.
Once the material was developed Sterling reports Emerald packaging worked to develop it into a packaging format that fit Popeye's needs.
One of the key issues was temperature endurance. Reportedly Earthfirst PLA has the highest temperature of 175' F allowing it to be applied in a number of instances. Earthfirst claims their PLA films have the highest temperature of any of the PLA films on the market.
Popeye Fresh Baby Spinach in PLA packaging is available at retail stores here in the US. Given the increased variety of applications PLA is suitable for, fresh produce packaging seems to make a great deal of sense for the material. Conventional forms of salad and spinach packaging is almost always discarded by consumers ending up in landfills.
