Common questions
How do I know if my item fits the 30" W x 3" L size?
The listed size is 30" W x 3" L. Plan for contents slightly smaller than the nominal size — the usable interior runs a bit under the listed measurement once the bag takes shape around what you load into it.
What does 4 mil film mean in practice?
A mil is one-thousandth of an inch, so 4 mil film is 4/1000" thick — 4 mil film, for example, is twice the film thickness of 2 mil. Heavier film of the same material stands up to punctures and rough handling better; lighter film costs less per bag and packs tighter.
Is there a drop-in substitute for PB1037?
Not as an exact replacement. The closest sizes in this line are 20" Length x 4" Width and 36" W x 4" H (Lay Flat); any size change alters the usable interior. Before switching, match the listed dimensions, 4 mil thickness, closure type, and case count — then reorder by exact SKU PB1037.
How do these bags close, and how are they shipped?
The closure is listed as Twist Ties, Bag Tape, or Impulse Sealers (sold separately), so the bag closes without separate tape or heat. This listing is sold as one case of 1,000 bags — roughly $0.13 per bag at the current case price (confirm the live price before ordering). Orders ship from Packrift's five US warehouse regions (Central IL, NE PA, S TX, SE GA, and W CA); delivery options and timing are shown at checkout.
