box liner in cardboard box

Our Box Liners are actually industrial strength barrier bags. Think of them as providing a clean barrier to the permeable outside carton. These are not standard polyethylene liners; we prefer polyester (Mylar) with a foil laminate structure to provide a stable package with moisture and oxygen barrier properties as well as puncture resistance. Commonly found in the application of export packaging for nut meats, nutritional supplement mixes, microencapsulated fish oil, and a wide range of non-food products, including plastic resin pellets and polymers.
