The brand “SNL” stands for “Sniten Manufacturing L.P.”. The company is a manufacturer of industrial and scientific packaging and shipping supplies. They are also the world’s largest producer of polystyrene containers, which are used in food, pharmaceutical, medical, chemical, energy, and industrial areas. The process to manufacture these containers is fairly complex. It starts with a mixture of hydrocarbon resins, which are mixed with one or more other materials to produce a type of polymer resin. This mixture is then heated and extruded through a heated die to form the shape desired. This is then cooled into a sheet that can be cut into the desired shape and then be formed into the container that will house the product inside. The finished product is then placed in ovens to harden the material. There are many benefits to using polystyrene containers in the food industry, including its durability for temperature extremes, its insulating properties to keep products cold or hot for extended periods, its resistance to shattering during transportation or storage, and its ability to be recycled multiple times over. SNL has been manufacturing polystyrene containers since 1916 and is part of the global market leader in container production with around 15 percent of the market share.
