Is a tougher improved Styrene Maleic-anhydride copolymer resin for microwave packaging requiring "freezer to microwave" and ESCR performance. The reheated stiffness is better than PP and it can be exposed from - 40 to 250°F. Prime Micro-X is compatible with existing lid sealing films and is FDA approved. Applications: Food packaging for freezer to microwave. Prime Micro-X was compared to PP and filled PP for food packaging from 150 to >250°F filled with pancakes, muffins, pizza, sausage, chicken patties and bacon. The three materials passed the test with the exception of bacon and PP and filled PP ruptured, where the Micro-X had only a dimensional change. Processing: Prime Micro-X thermoforms similarly to Polystyrene. The same forming tools can be used for both materials. Finishing: Prime Micro-X can be trimmed with steel rule or hard trim dies. Please contact your Primex Plastics representative for more information on finishing, fabricating, or the thermoforming process. Colors, Textures and Capabilities: Colors are typically white, black and pastels but custom color matching is available by request. Textures include smooth and matte. Prime Micro-X comes in a wide variety of size and gauges. Please contact your local Primex Plastics representative for details.
