Profile: Brentwood Plastics, Inc. specializes in custom blown polyethylene film. All of our polyethylene resins are derived from natural gas. Most of our products are used for some form of packaging. We manufacture Regresa® oxo-biodegradable polyethylene films. We manufacture shrink films for unitizing, most commonly for trays of cans or bottles reducing corrugated usage. Our Redi grade was developed specifically for film-over-film, or shrink wrapping over printed LDPE shrink films without melting into the printed film.
