Tri-Plex Packaging Corporation

The stretch of Fifth Avenue between 23rd and 28th Streets has long been a hub for businesses that operate behind the scenes—places where branding, logistics, and strategy take shape. Among them is Tri-Plex Packaging Corporation, a marketing consultancy that works with clients on packaging design, distribution logistics, and market positioning. The area’s mix of historic office buildings and modern commercial spaces makes it a practical base for firms that serve regional and national clients without needing a flashy storefront. While the name might suggest a focus solely on packaging, the consultancy’s role often extends into broader marketing strategy, helping businesses align physical presentation with digital outreach.

Finding the office is straightforward: it’s at 245 5th Ave #1503, New York, NY 10016, a midtown address that puts it within walking distance of both Penn Station and the Flatiron District. For direct contact, the phone line is available at 212-684-1900. Since the building houses multiple businesses, checking the suite number in advance saves time. Those planning a visit can pull up directions here—the entrance is on Fifth Avenue, where the sidewalk stays busy even on weekdays. This part of Midtown South remains a quiet counterpoint to the tourist-heavy blocks uptown, offering a more work-focused rhythm.
