UPACO Footwear Products



These patented films have been developed to bond to various soling and midsole materials for permanent sole-attaching. Depending upon the substrates to be bonded, the films may be used in-mold or post mold. Standard films are available for bonding PU and EVA materials. Because of the wide variety of rubber compounds our technical sales crew will work with the customer and/or compounder to develop films for specific rubber materials.


These films may be used to eliminate stitching required on uppers for design purposes. The single layer films may be used to permanently combine mesh, synthetics, PVC, TPU, and other materials. By choosing the appropriate coextrusion, one side will seal to the surface of the upper while the other may be printed or colored to give the desired effect without laminating.

We welcome the challenge to develop a custom solution to meet your requirements.

Biodegradeable Solutions: Ecobond H20 BD

EcoBond H2O BD is a one-part, low-temperature activating, inherently biodegradable, waterbased urethane adhesive. It offers remarkable performance features for bonding primed soles of SBS, TPR, or plantation crepe as well as soles made of PVC and primed/treated soles of urethane or composition stocks to a variety of upper materials. Reactivation temperature as low as 120F - 125F consistently provides high quality bonds. This serves to eliminate the risks associated with exposure of softer rubbers to the higher reactivation temperatures required by other available types of adhesives. EcoBond H2O BD demonstrates excellent initial green strength and spotting tack, and good initial heat resistance. EcoBond H2O BD can be used in brush, roller, and spray applications.


Our solvent-based adhesives and primers are available for all aspects of footwear and allied industry manufacturing, from sole-attaching to socklinings and general combining. Technology, substrates, and customer requirements are changing constantly and we change with them. We have developed an RSL (Restricted Substances List) that mirrors the most stringent list our customers ask us to comply with.

Both natural and synthetic water-based seam sealers are available to complete the waterproof package. Whether used with PermaSeal®, booties, or just waterproof leathers, these sealers will stop water from entering the shoe through stitched upper seams. All systems require 2 coats – the first to seal leather fibers and stitch holes; the second to give a firm, flexible, pinhole-free top coating.


This patented technology is based on the concept of "stitch-a-hole/seal-a-hole", to provide an exceptionally high level of waterproofing for Goodyear Welts, Littleway, and 3 Needle constructions.
