Over the last week the trend has definitely been towards PP tray packaging similar to the red tray pictured here. Polypropylene has a high heat deflection temperature that allows it to be used in applications that need to be, for instance, dishwasher safe. It is quite often used in food contact applications like cookie trays and other baked goods. PP is not widely used in custom thermoforming due to the difficulties involved in forming it along with possible needs for additional equipment and/or highly skilled technicians. Shepherd has the staff and ability to form PP as these examples show. We also build the tools to suit small or large volume needs. Shepherd Thermoforming & Packaging Inc. does not compete with the off the shelf (proprietary) type products like a yogurt cup but for custom applications our tool cost can help launch a new product quickly at a fraction of the cost of a proprietary start-up. Once the volume justifies the leap to a proprietary tool, we will help with the transition with hopes of developing new business from the relationship.
