San Francisco is one of the most critical hubs for biotechnology, pharmaceuticals, clean manufacturing, food distribution, high-value electronics, and port logistics on the West Coast. With nonstop freight movement along US-101, I-280, the Bay Bridge corridor, and the broader Bay Area supply chain—plus proximity to the Port of Oakland, major research labs, cold-storage facilities, semiconductor suppliers, and advanced manufacturing centers—San Francisco businesses rely heavily on custom poly bags to protect goods from moisture, contamination, abrasion, and precision-handling requirements.
Custom Packaging Products supplies bulk custom poly bags to biotech labs, pharmaceutical manufacturers, food processors, produce importers, medical-device companies, electronics and semiconductor suppliers, aerospace facilities, retail distributors, and 3PL warehouses across San Francisco, Oakland, Berkeley, Daly City, South San Francisco, San Mateo, Fremont, Hayward, and the entire Bay Area. Our poly bags are engineered for coastal humidity, cold-chain demands, cleanroom environments, temperature variation, and export-driven logistics.

San Francisco Case Study
A biotech manufacturer near Oyster Point struggled with:
- Condensation on packaging in foggy weather
- Static buildup affecting sensitive devices
- Inconsistent clarity interfering with visual inspection
After switching to CPP’s high-clarity, anti-static custom poly bags:
- Static-related issues decreased by 46%
- Fog-related moisture infiltration became negligible
- Inspection efficiency improved across product lines
CPP poly bags are now used for all outbound lab and device packaging.
