Reclosable Poly Bags for Bulk Shipping

Partners Brand PB3841 bags measure 20 by 30 inches and come in a pack of 250. The 4 mil thickness provides a sturdy barrier for mailing or storage tasks. Transparent material lets you identify contents without opening each bag. The reclosable seal supports repeated access while keeping items protected.

Durable Plastic Construction for Daily Handling

Four mil polyethylene resists tears and punctures during normal packing and transit. The smooth surface slides easily into boxes or onto shelves without snagging. No powered equipment or special ventilation is required for use. The lightweight bags add minimal mass to shipments.

Pack of 250 Suits High Volume Operations

Each box delivers 250 bags, reducing reorder frequency for mailrooms and fulfilment desks. The reclosable lip closes by hand, so no heat sealer or tape dispenser is needed on the line. Transparent walls allow quick visual checks during quality control. Flat storage keeps the supply tidy until the next batch is required.

Questions about this item

How do I open and reseal the 4 mil reclosable poly bag without damaging the closure?

Press the interlocking tracks together firmly along the full 30 inch length until you hear a click; avoid pulling the bag sideways while sealing as that can misalign the tracks.

What wear should I expect on the zipper track after repeated opening and closing?

The 4 mil polyethylene tracks stay functional for many cycles; replace a bag once the tracks no longer snap shut cleanly or show visible stretching.

At what load does the 4 mil material start to tear under sustained weight?

The 4 mil film handles typical mailing loads; sharp or heavy items exceeding the bag's puncture resistance will cause the first tears.
