What source facts are used here?
20 x 18 x 36; clear poly; clear; 100 pack
Gusseted poly bags: Good fit for bulky, irregular, or deep items that need expandable side or bottom space. These poly bags help fulfillment, warehouse, ecommerce, and parts teams choose right-sized bags for storage, kitting, packing, and shipping workflows.
Common questions
Will a boxy or bulky item fit in this 20" W x 18" D x 36" H bag?
The listed size is 20" W x 18" D x 36" H — the gusseted sides fold out so the bag can open to its listed depth and sit around blockier items. The catalog lists inside-usable dimensions of 20" W x 18" D x 36" H, so that measurement is what your item has to fit within.
How does 4 mil compare with lighter or heavier film?
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. This listing's material is specified as 4 Mil Low-Density Polyethylene (LDPE).
Is there a drop-in substitute for PB1850?
Not as an exact replacement. The closest sizes in this line are 12x8x30" and 28x24x60"; any size change alters the usable interior. Before switching, match the listed dimensions, 4 mil thickness, and pack count — then reorder by exact SKU PB1850.
What do I need to seal these, and what does a full order look like?
These are open-top bags — close them with a heat sealer, bag tape, twist ties, or staples, whichever fits your workflow. This listing is sold as one pack of 100 bags — roughly $1.54 per bag at the current pack 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.
