Tyvek® for Food Packaging

DuPont™ Tyvek® protects food quality and extends shelf life through its usage in active and intelligent packaging. It can be used during every stage of the food chain to keep produce fresh.

DuPont and its partners have developed innovative ways to protect perishables and to reduce the spoilage of food through various solutions for wrapping, bagging, covering, encapsulating, interleaving and protecting. Breathable, water-resistant Tyvek® is useful in food production too and has been put to imaginative uses, including as a means to apply coatings to different food products, like spice coatings on sausages and ham. The breathability and the protective qualities of Tyvek® for food packaging make it a perfect partner in agriculture as well. It has been used as tree base wraps, ground protection, and for freeze control, to name a few ways Tyvek® helps bring quality food to the table. Because it comes in a highly reflective white style, lightweight, reusable Tyvek® has even been laid on the ground to reflect sunlight to the bottom of oranges, to help ripen the underside of the fruit. It has also been used to protect dates on the tree and to cover mulberry bushes planted to feed silk worms, both of which are exposed to damaging rains.

Using Tyvek® to protect perishables during air transportation and transit (a typical example is asparagus shipped from Peru to the world) can extend shelf life and decrease your loss rates dramatically and thereby increase profitability. It is estimated that 20 to 30% of food profit losses derive from spoilage between the time the food is prepared or harvested and the time it is made available for the consumer. This is a very significant bite into profits which can be greatly reduced by using Tyvek® for food packaging to help stabilize external variables like temperature, light and moisture. Tyvek® reflects up to 95% of the UV rays and prevents condensation that could lead to mold and rot. It is also a bacterial barrier that avoids contamination from bacteria like salmonella inside a closed system. The diverse and extremely practical uses that the food industry has already found for Tyvek® should serve to whet the appetite for even more innovative applications in this large and growing sector.
