About this item
SKU PB3989 — 12" × 18", 2 Mil, Clear. Sold as a case of 1000, shipped from US warehouses.
12x18" white reclosable poly bags in 2 mil polyethylene, the most popular general-purpose weight for light to medium weight products. Packed 1000 per case (SKU PB3989); this is a second listing of the same BOX case stock at the same price.
Open-top reclosable design: seal with twist ties, bag tape, or an impulse sealer (sold separately). Keeps parts, hardware, and products visible while protecting them from dust and moisture. Order by the case of 1000.
Common questions
How much usable room does the 12x18" size really have?
The listed size is 12x18". The catalog lists inside-usable dimensions of 12" Width x 18" Height, so that measurement is what your item has to fit within.
How does 2 mil compare with lighter or heavier film?
A mil is one-thousandth of an inch, so 2 mil film is 2/1000" 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. This listing's material is specified as Low-Density Polyethylene (LDPE), 2 Mil Thickness.
Is there a drop-in substitute for PB3989?
Not as an exact replacement. The closest sizes in this line are 12x15" and 14x20" (same 2 mil film), and the same 12x18" size is also stocked in 4 mil. Before switching, match the listed dimensions, 2 mil thickness, closure type, and case count — then reorder by exact SKU PB3989.
How does the closure work, and what does a full order look like?
The closure is listed as Reclosable Zipper with White Write-On Block, so the bag closes without separate tape or heat. This listing is sold as one case of 1,000 bags — roughly $0.19 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.
