FPI Rigidity Tester

In 2007, FPI announced that production and shipment had begun for the Institute’s modernized rigidity tester used by manufacturers for testing rigidity (resistance to bending and buckling) of single-use foodservice packaging products.
The 2007 model of the tester is an electrified, digitized, and ergonomically-enhanced version of the Institute’s original rigidity tester developed for industry use 20 years ago. It has been used by the industry to determine the rigidity of paper and plastic plates, platters, bowls and trays used in foodservice venues.
FPI’s Foodservice Packaging Standards Council spent nearly a year developing its requirements for a new rigidity tester, and then monitored ten months of beta testing of the new unit at Georgia-Pacific Corporation’s DIXIE laboratory facility in Lehigh Valley, Pa. In addition to the testing device, the Council oversaw development of a new Operating Procedure for the tester.
The new device is being manufactured by Peerless Machine & Tool Corporation of Marion, Ind. Manufacturers and laboratories seeking to purchase the 2007 model of the rigidity tester may contact FPI for information.
If your company already has the updated rigidity tester but has questions or problems with the calibration, please contact Peerless Machine & Tool Corporation directly at (765) 662-2586.

Foodservice Packaging and… Styrene

/in

Foodservice packaging is made from a wide variety of materials. These products go through rigorous testing to ensure that they meet stringent regulations, ensuring the safe delivery of foodservice items to consumers.

However, there has been some confusion over the safety of polystyrene with the inclusion of “styrene” in the National Toxicology Program’s (NTP) 12th Report on Carcinogens in 2011.

Styrene is naturally present in foods such as strawberries, peaches, cinnamon, beef and coffee and is produced in the processing of foods such as beer, wine and cheese. It is also used to make polystyrene, a material used to make some foodservice packaging.

Polystyrene has been used in foodservice products like foam coffee cups, takeout containers and cutlery for more than five decades. During that time, polystyrene has been reviewed by various regulatory agencies and scientific bodies, which have deemed it safe for use in contact with food.

The NTP stated in its own report that “It is important to note that the reports do not present quantitative assessments of carcinogenic rise…Listing in the report does not establish that such substances present a risk to persons in their daily lives. Such formal risk assessments are the purview of the appropriate federal, state, and local health regulatory and research agencies.” So NTP did not conclude that styrene or plastic foodservice packaging made with styrene present any risk to human health.

Following the NTP report publication, several additional statements were released confirming the safety of polystyrene:

    • The U.S. National Institutes of Environmental Health Sciences noted “Styrene should not be confused with polystyrene (styrofoam). Although styrene, a liquid, is used to make polystyrene, which is a solid plastic, we do not believe that people are at risk from using polystyrene products.”
    • The toxicologist who heads NTP stated “Let me put your mind at ease right away about Styrofoam,” noting that levels of styrene from polystyrene containers “are hundreds if not thousands of times lower than have occurred in the occupational setting…In finished products, certainly styrene is not an issue.”

Furthermore, in 2013 the American Chemistry Council’s Plastics Foodservice Packaging Group provided updated styrene migration data to the Food & Drug Administration (FDA). The data show that current exposures to styrene from the use of polystyrene food contact products remain extremely low, with the estimated daily intake calculated at 6.6 micrograms per person per day. This is more than 10,000 times below the safety limit set by FDA (the FDA’s acceptable daily intake value of styrene is calculated to be 90,000 micrograms per person per day).

Single-Use Versus Reusables: The Good, The Bad and The Yucky

Single-use versus Reusable Foodservice Packaging: The Good, the Bad, and the Yucky

Foodservice packaging like paper and plastic cups, plates and bowls were invented over 100 years ago to provide a more sanitary alternative to their reusable counterparts and help protect public health. Over the years, the Foodservice Packaging Institute has commissioned independent studies with third-party laboratories to confirm the sanitary advantage of single-use foodservice packaging over reusables.

Before you choose that ceramic mug over a paper or plastic cup, you may want to know what the latest study shows. In 2012, health inspectors visited 30 different foodservice establishments in Sacramento County, Calif. and swabbed nearly 300 single-use cups, plates, bowls and cutlery and their reusable counterparts. These swabs were sent to a laboratory for testing, and here’s what they found:

    • Evidence of Enterococcus and Staphylococcus – bacteria that can cause diarrhea, cramps, nausea, vomiting, fever and chills – was below the detection limit on both the single-use and reusable items. Certainly good news for the foodservice industry.
    • Not such good news when it comes to coliform bacteria, which is usually traced back to fecal matter (ewww!) and can cause bloody diarrhea, severe abdominal pain, cramps, nausea, vomiting and occasionally fever. If that’s not bad enough, it can be fatal in the young, elderly and immune-compromised. The results of the swabs taken in Sacramento County showed evidence of coliforms on four percent of reusable items and on none of the single-use items. Hmm, wonder what would have happened to those lucky customers if they had been served the reusable plate, bowl and spoon that the laboratory determined had over six times the coliforms?!?!

Another test was the mere presence of bacteria, which could indicate a food safety or public health hazard. Single-use items were again shown to be more sanitary, with statistically significant lower bacteria counts compared to the reusable items. Consider these test results:

    • Over one-third (gulp!) of the reusable plates and bowls tested had higher than acceptable microbial levels, compared to nine percent of single-use cups.
    • One quarter of the reusable forks, knives and spoons tested had higher than acceptable microbial levels, compared to just over ten percent of single-use cups.
    • Seventeen percent of reusable cups tested had higher than acceptable microbial levels, compared to only seven percent of single-use cups.

Time after time, sanitation studies prove that single-use Foodservice Packaging is The Sensible Solution.
