Barrier Adhesives

The packaging and medical / pharmaceutical industries are the largest industries to use adhesive systems having specific permeability requirements. Most often the requirement is for low permeability or "barrier" properties - to keep oxygen...
Coating and Laminating

Lamination is used to produce a film structure consisting of two or more layers of materials (films, foils, paper, etc.) by adhesive bonding. The adhesive is applied in a coating process. This approach is generally used when one material will not...
Cold Seals

Cold seal adhesives are those that bond when exposed to pressure only. They are often referred to as pressure sensitive adhesives. They are formulated so that tack to non-cold seal surfaces is minimized (blocking resistance). They are generally...
Extrusion

Extrusion is a method of making a laminate in which two or more thermoplastic materials are extruded separately and combined either internally in the die or immediately after leaving the die. The extrusion process is generally preferred over the... (1 Member Reaction)
Food Contact

Many applications of flexible packaging adhesives require compliance with regulations for direct or non-direct food contact (e.g., Food and Drug Administration, FDA). An adhesive, coating, or ink used in the packaging of a food item for human...
Heat Seals

A heat seal is a thermoplastic adhesive that is generally applied to the substrate as a molten liquid coating and cooled to a solid or as a solventborne or waterborne coating and then dried to a solid. Then, when a bond is required, the coated...
Low Surface Energy Films

Thermoplastic materials often have a lower surface energy than thermosetting materials. Thus, physical or chemical modification of the surface is necessary to achieve acceptable bonding. This is especially true of the crystalline thermoplastics such...
Medical

Typical applications for PSAs in the health care industry include wound coverings and closures, surgical drapes, ostomy mounts, electrocardiograph electrode mounts, electrosurgical grounding pads, and transdermal drug delivery.Medical adhesives must... (1 Member Reaction)
Packaging

Packaging tapes are generally used for sealing and preventing pilfering or contamination. Packaging tapes are generally made from high tear biaxially oriented polypropylene film or polyester film backing. Many of these adhesives have a fabric...
