About Apertured Films

SWM Apertured Film provides purity, high-strength, and non-stick properties for critical applications.         


We manufactures geometric apertured films under the Delnet brand. Delnet apertured films and bags, have a mesh-type configuration, made from a unique extrusion, embossing, and orientation process. By varying the process parameters, an infinite variety of configurations can be created to meet our customers’ requirements.  Tensile strength, product weight, chemical formulation, hole size, and geometry, are some of the features that can be customized to meet your application and market requirements. The Delnet line of apertured films can also be co-extruded to serve as adhesive bonding layers.  Delnet is used for cost-effective tack bonding, laminating, a combination of tack bonding and laminating, or surface modification.


For example, our apertured film can provide a non-adheant layer for wound pads, a flexible surface layer for medical face masks or an outer dust release layer in air filtration applications.  From cheese production and fabric bonding to pollination and gardening applications, SWM apertured films can be used alone or in composite form laminated to different substrates.


We understand that every customer has specific film requirements, so whether you are improving an old product or developing something completely new, contact our team at ams@swmintl.com and let us collaborate on your next product development project.
