Shipping & Mailing Supplies

Partners Brand PB3788 reclosable poly bags measure 12 by 16 inches with a 4 mil thickness. Each pack contains 500 transparent bags. They suit mailrooms, warehouses and small businesses that ship flat items in volume. The reclosable seal allows repeated opening and closing during packing.

Thermals noise and power draw

These bags have no electrical components so they produce no heat, noise or power draw. They are passive packaging materials intended for storage and transit. Performance depends only on the strength of the polyethylene film and the zip-track closure.

Sustained load behaviour

Under continuous use the 4 mil polyethylene resists tearing and punctures while the zip track maintains its seal over many cycles. The 500-count pack supports high-throughput shipping without frequent reordering. Buyers who need heavier-duty film or larger dimensions should consider other specifications.

Questions about this item

How do I seal the 12 x 16 inch reclosable bag correctly, and what step do people often miss?

Press the zip-track together firmly from one end to the other using your thumb and forefinger; the step most people miss is running a second pass to ensure no tiny gaps remain along the 4 mil seam.

Will the zip-track on these 4 mil poly bags wear out, and when should I replace a bag?

The reclosable seal is rated for repeated opening and closing; replace a bag when the tracks no longer align cleanly or when the 4 mil film shows stress whitening at the corners.

At what load does the 4 mil thickness typically fail first during sustained packing use?

The 4 mil film reaches its limit first at the bottom corners when the bag holds heavy, sharp-edged items that concentrate stress on a small area.
