Food and Drug Administration. Regulations for PS applications apply to the following area: Adhesives: (1) Direct food contact, such as labeling of fruit and vegetable with an edible skin (175.125); (2) Indirect food contact, where incidental between an adhesive and a food may be possible (175.105). Facestocks: (1) Contact between paper and dry foods (175.180); (2) Contact between paper and aqueous and/or fatty foods (176.170).

A jagged irregular paint line frequently characterized by small “feathers” of the top-coat projecting into the masked area.

Thin longitudinal “threads” of glass, polyester, nylon, or other high-strength materials.

Uniform, homogeneous, nonfibrous synthetic webs.

Acetate, polyester, polyethylene vinyls and other polymeric. Face material manufacturing from synthetic high molecular weight polymers.

The surface property of a film determined by its texture and gloss. A gloss finish, for example, can be shiny and highly reflective, while a matte finish is generally dull and reflects little light.

Coatings.Round or oval deformation in an adhesive, coating, or ink. Indicative of either surface contamination, or of “non-wetting” of a surface by an adhesive, ink, or coating because of surface tension problems. Surface defect for quality problem.

Tapes relative to PSA aesthetics-Relatively small deformations (pock marks) in the adhesive caused by the entrapment of air between layers in the roll. They are not an indication of a quality defect.

A peeling away from the surface of the end of a length of tape, particularly in a spiral-wrap application.
