In 1979, the key personnel of what is now WEIGHTPACK, were the first to introduce electronic control of net weight filling to the industry. Since then, we continue to lead the industry with the latest design and technology for our customers. Serving industries ranging from dairy to pharmaceutical, personal care to paint, our machinery is available in a variety of standard pitches (distance between nozzles) and valve numbers – with custom options available depending on your needs. Our rotary models are capable of filling between 20-500 containers per minute, and for slower lines or larger containers, we now offer inline fillers that can process up to 25 containers per minute. Our stainless steel/steel frame equipment features laminar flow nozzles and Clean in Place (CIP) technology, along with anti-corrosion and explosion proof options. Significantly, WEIGHTPACK’s electronic net weight filling ensures that our filling machines keep true weight under each station. Electronic control (PLC), weigh cells, and filler/capper monobloc are all critical components in securing true net weight. (Note that tri-bloc and quadro-bloc designs are also available.) Accuracy can be guaranteed as part of the contract, based on tests conducted on the customer’s product on our laboratory fill test unit.

An international company with headquarters in Italy and the U.S. (greater Richmond, VA area), WEIGHTPACK also provides multi lingual manuals, and comprehensive training for all of our products.
