The BSC PREFERRED PB4219 is an extra heavy-duty poly bag designed for protecting industrial parts, tools, and heavy-weight components from dirt, dust, and moisture. Manufactured from 100% virgin, high-clarity polyethylene film, these bags are puncture resistant and built to handle demanding storage and packaging applications. The material meets FDA and USDA specifications, making them suitable for a range of trade and industrial environments. Each case contains 500 bags. Closures are compatible with twist ties, bag tape, or impulse sealers, giving installers and warehouse staff flexible sealing options depending on the workflow.
These poly bags are well suited for packaging and protecting industrial parts, HVAC components, plumbing hardware, electrical fittings, and similar trade supplies. They are commonly used in maintenance shops, wholesale supply houses, and field service operations where parts must be protected during storage or transit. The high-clarity film allows for visual identification of contents without opening the bag, which speeds up parts handling on the job.
Designed as a general-purpose heavy-duty poly bag for packaging and protecting industrial parts, tools, and trade-supply components requiring moisture and dust protection.
No tools or trade license are required for use. Store cases in a dry location away from direct sunlight to preserve film integrity. When using an impulse sealer, follow the sealer manufacturer's operating guidelines to achieve a consistent, airtight seal. Bags should be selected based on the dimensions and weight of the contents to avoid overstressing the film.
