In today’s world, packaging integrity serves the highest purpose for any food or drug company. If they are unable to deliver their products safely without tampering to the public then they would not be able to sell anything. Consumers demand that their food and drugs must be guaranteed fresh, safe, and cost effective. Companies place the highest regard to the safety and integrity of their products packaging but in today’s changing environment this can be quite challenging. This is where Lenox Laser has the expertise and knowledge to help companies create standards that can be used to help test their packaging even in a production line.
Recent research, such as Earl Hackett’s study explained in “How Pinholes Affect Packaging” in the July 2000 issue of PMP News, indicates that in flexible packages with breathable barrier materials, the nature of flow and the mobility of bacteria may in fact make penetration difficult with holes up to 50 µm. (According to Hackett, the data showed that essentially all particles that entered the hole exited on the far side. The flow through the entire package was split between the hole and the Tyvek or paper. The number of particles detected coming through the 100-mm diameter sample of barrier material was statistically the same with or without the hole until the hole reached a minimum diameter of 50 µm.)
