What Metro Poly does

Metro Poly Corp. is a US-based plastic bag and film manufacturer founded in 1990 and headquartered in San Leandro, California. The company runs an integrated polyethylene film extrusion and bag conversion operation, with related entities in San Leandro (Uni Poly Inc) and Houston, Texas (Pro Plastics Inc). It produces roughly 16 SKUs spanning plain and printed bags, bottom/side seal bags, produce bags, wicket, header, lip-and-tape, tamper-evident, T-shirt, and die-cut handle retail bags, plus trash bags, garment bags, sheeting, tubings, and compostable bags. Manufacturing follows a four-stage in-house process: design preparation (artwork and print plate design), film extrusion of polyethylene resins to spec, multi-color printing, and conversion into finished bag/roll/sheeting SKUs.

The company targets a horizontal B2B customer base across retail, food service, manufacturing, and general commercial end markets in the United States. Its stated positioning is built on Made-in-USA production, customization (variable film sizes, thicknesses, multi-color printing, custom artwork), and quick-delivery service for small-to-medium quantity orders — a niche many high-volume converters underserve. Customer acquisition is sales-led via direct B2B outreach and a basic website storefront (metropolybag.com) with phone, fax, and email intake; no marketing channels, no e-commerce SKU purchase flow, and no digital sales infrastructure are indicated in the source data.

Revenue is generated almost entirely through one-time hardware sales of manufactured bags and films to B2B buyers on a per-order, quote-based pricing model with no publicly disclosed price list. The company is privately held with no disclosed funding rounds, no parent entity, no executive team in the public data set, and 1-10 reported employees. In October 2025 Metro Poly was named in a California-led settlement requiring it to halt plastic bag sales in California and pay $1.8 million over alleged false recyclability claims — a material jurisdictional headwind against an otherwise stable, long-tenured niche industrial profile.

Direct peers

• Crown Poly: Crown Poly manufactures plastic bags and films including T-shirt bags, produce bags, and custom-printed bags for retail and foodservice customers. It is a direct peer given shared product categories and B2B distribution approach.
• Elkay Plastics: Elkay Plastics manufactures and distributes plastic bags and films across a broad product range including food, retail, industrial, and specialty bags. It is one of the closest direct competitors to Metro Poly given overlapping SKU categories and B2B wholesale distribution model.
• Advance Poly-Packaging: Advance Poly-Packaging is a custom polyethylene film extruder and bag converter producing printed and converted bags for industrial and retail customers. It is a direct peer given similar in-house extrusion, printing, and converting capabilities.
• Rutan Poly Industries: Rutan Poly Industries manufactures polyethylene film and plastic bags, including custom printed bags for retail and specialty applications. It is a direct comparable peer based on overlapping custom film extrusion and bag conversion operations.

Broad incumbents

• Hilex Poly (HQC/Hilex): Hilex Poly / Novolex HQC manufactures a broad range of plastic bag products including retail and institutional bags, with recycling and sustainability initiatives. It overlaps Metro Poly in produce and retail bag categories at much larger scale.
• Novolex: Novolex is a large North American manufacturer of paper and plastic packaging products, including bags and films. Its breadth across substrates and customer segments places it as a broad incumbent in the same space as Metro Poly's polyethylene bag business.
• Poly-America: Poly-America is a major producer of polyethylene film products and plastic bags, including consumer and industrial trash bags. It serves similar end markets to Metro Poly at much higher volume, making it a broad incumbent rather than a direct niche peer.
• Inteplast Group: Inteplast Group is one of the largest North American manufacturers of polyethylene films, bags, and related plastic packaging. It competes broadly with Metro Poly in plastic film extrusion and bag conversion, but at significantly greater scale across multiple product categories beyond bags.

Emerging players

• Papier-Mettler: Papier-Mettler is a leading European manufacturer of compostable and bio-based bags including certified compostable produce and retail bags. It is an emerging/adjacent player addressing the same sustainability-driven substitution trend that Metro Poly's compostable line targets.

It represents an emerging competitor focused on the compostable/biodegradable segment where Metro Poly is also building capability.
