Medical Packaging

Many pouches made for the health care industry are made with medical grade DuPont™ Tyvek® material on one side and a clear laminate on the other. These specialty pouches, often referred to as chevron pouches, are used for products which are sterilized, and the two sides are peeled apart to open the package. Foil laminates are also often used by medical customers for the highest level of barrier protection available.

Whether you need pouches for testing and validation, are starting a new project, or simply require pouches to help cover inventory, we can help you meet your goals with our DuPont™ Tyvek® pouches. Available in various sizes.

Consumer & Retail Packaging

Most packaging for consumer and retail (food) products must have barrier qualities that keep the contents fresh for an extended period of time. The two most common barrier requirements are for water vapor and oxygen. Different food products will have different barrier requirements.
