Barrier Bags

KNF FLEXPAK Corporation and KNF Clean Room Products Corporation manufacture custom barrier bags for applications that require protection from moisture, gases, chemicals, contaminants, and other environmental conditions. With more than 50 years of flexible packaging experience, KNF produces Nylon, polyethylene, and multilayer film products for industrial, food, medical, pharmaceutical, aerospace, electronics, and cleanroom applications.

Custom Barrier Bags for Specialized Packaging Requirements

Packaging requirements can vary significantly based on the product, handling conditions, and storage environment. KNF provides custom barrier bags made to meet specific packaging needs, with options for material, size, gauge, construction, and other specifications.

KNF's film extrusion and converting capabilities allow customers to select materials suited to their applications. Whether you need packaging for industrial components, chemicals, food products, or sensitive equipment, KNF can help identify an appropriate film and bag construction.

Custom barrier bags can also be produced in different sizes and thicknesses, giving you greater control over how products are packaged, stored, and transported.

Barrier Protection Against Moisture and Environmental Exposure

Moisture, gases, chemicals, and other environmental factors can affect products during storage and transportation. KNF offers film materials with barrier properties suited to specific packaging requirements.

Polyethylene films provide low water vapor transmission characteristics, making them useful for applications that require moisture control. Nylon films offer gas and aroma barrier properties along with resistance to chemicals, abrasion, and demanding handling conditions.

For products that require added moisture protection, moisture barrier bags can provide a practical packaging option. KNF can help match the film construction to the conditions your packaged products will face.
