What International Plastics does

International Plastics, Inc. (operating as Interplas) is a Greenville, South Carolina-based manufacturer, importer, and wholesale distributor of flexible plastic packaging, founded in 1964. The company sells five core product categories: custom printed packaging, bags and liners, tubing and film, packaging supplies, and specialty packaging. Its underlying technology consists of in-house film extrusion, printing, and converting equipment supplemented by imported finished goods, supported by an ISO 9001 quality system and a 9,000+ SKU inventory with 3,000+ poly bag sizes.

The business operates a hybrid go-to-market: a self-serve e-commerce storefront (interplas.com) with same-day shipping on in-stock items ordered before 4 PM EST, paired with phone and email sales channels that handle custom packaging quotes and enterprise orders. Revenue is generated one-time on each order under a factory-direct pricing model with a Lowest Price Guarantee; custom pricing is driven by size, material structure, quantity, printing, SKU count, closures, and barrier requirements. Free packaging consultations and two hours of free artwork time are bundled into custom orders to reduce buyer friction.

The customer base spans consumer packaged goods, food service, e-commerce, retail, healthcare, government, hospitality, and industrial buyers. The website displays 30+ named logos including McDonald's, PepsiCo, Hershey, Campbell's, Walmart, Costco, Home Depot, NASA, Netflix, Ford, Honeywell, and GE. The firm is privately held with no disclosed external investment, is led operationally by Roger Throckmorton (Chief Brand Director), and reports 11-50 employees with more than one million cumulative orders fulfilled.

Direct peers

• Printpack: Privately held US manufacturer of flexible and specialty packaging, including pouches, films, and rollstock for food, beverage, and consumer products. Comparable in product mix (custom printed flexible packaging) and customer overlap in CPG.
• Bryce Corporation: Privately held US flexible packaging converter producing printed films, laminations, and pouches for food, beverage, and industrial markets. Direct competitor in custom printed flexible packaging serving similar CPG and industrial accounts.
• PolyPak America (PolyPak Packaging): US manufacturer and converter of polyethylene bags, films, and flexible packaging products serving industrial, retail, and food customers. Closest head-to-head comparison to Interplas as a similarly sized poly bag and film producer.
