Clamshells, that clear plastic packaging you find in your local supermarket’s produce department has become a mainstay after being introduced a couple of decades ago.
Now, manufacturers of clamshells for strawberries and other fresh produce commodities have been tweaking the dimensions to satisfy both consumer desires and industry concerns.
The one-pounder is the clamshell is most popular, but other sizes, including the two-pounder and four-pounder, are gaining favor. Produce truckers may even notice some new packaging configurations. For example, F-D-S Manufacturing Co. in Pomona, CA, has introduced a two-pound clamshell with three different sizes, each of which allows for an eight-down pallet stacking configuration.
The three sizes of the clamshell and the ability to be packed in a tray that goes eight down on a pallet are equally important. While the outer dimensions of the clamshell remain the same, the inside needs to change a bit to fit different sizes of strawberries. As the season progresses, the average size of a berry changes and the inside dimensions of the clamshell must change to hit the weight advertised. Larger berries tend to be less dense so the clamshell has to be bigger to still get to the two-pound weight. Smaller fruit utilizes the inside space better and less mass is needed to reach two pounds of fruit. The same principle holds true when dealing with one or four-pound clamshells.
The eight down trays allow for better utilization of the cube of a refrigerated big rig trailer. In fact, with an eight down pallet, 30-35 percent more trays can be put in a truck. That is a huge freight advantage. The same freight advantage applies when shipping the empty clamshells to the grower. While this provide a freight advantage for the shipper, is the added weight enough to significantly cut into the what is being paid to the truck?
The four-pound clamshells also fit well in an eight down pallet configuration. Creating a one-pounder that offers that same freight advantage has been difficult.
The clamshell manufacturing industry has evolved over the years, and now virtually all the pellets being used to start the produce industry clamshells process come from recycled soda bottles. Depending upon the quality of the shipment, a small percentage of virgin material may have to be added to reach the quality level needed in the resulting clamshell. But overall, well over 90 percent of the material ultimately used comes from recycled product. And the clamshells themselves are recyclable.
Clamshells took over from plastic baskets in the strawberry industry more than two decades ago and now they account for at least 90 percent of strawberry containers.
