The 901 system intended for medium to high volume applications where pouring larger quantities of foam for larger cushions is required. The entire family of protective Instapak® foams in all container sizes are available. This system is ideal for applications where a large variety of product sizes and configurations are being packaged. Also ideal for very large products and applications. As a business grows and volume increases, the 901 system can be upgraded to use 275 gallon containers.
