How to fill and seal it

1
Fill
Fill through the open end — by hand, with a scoop, or on a filling line. Leave a few inches of clean, dry film at the top for the seal.
2
Vacuum
For a vacuum pack, place the open end across the seal bar of a chamber vacuum sealer and run the cycle. For a plain heat seal, skip to the next step.
3
Seal
Heat-seal the open end with an impulse sealer, band sealer or the sealer in the vacuum machine. The bag is sealed on the other three sides already.
4
Store or ship
Label the pack. The gray Mylar film keeps light off the contents and gives a flat, stackable pack.

Questions and answers

Yes. Orders made up of packs ship free by UPS Ground anywhere in the contiguous US. If you add film rolls or other products to the same order, shipping for the whole order is calculated at checkout and is free over $299. Faster UPS services are offered at checkout for a charge.

Packs ship from stock at our warehouse in Santa Clarita, California. UPS Ground transit within the contiguous US is typically 3–5 business days.

Set the quantity of packs in the order box at the top of the page. At 2, 5 and 10 packs the price per pack drops automatically — $28.95, $26.95 and $24.95 — and shipping stays free. For thousands of bags, a different size or printed bags, request a quote and we will price the run.

The bag is a smooth (non-embossed) Mylar-type barrier bag. Chamber vacuum sealers take smooth bags like this one. Many countertop clamp-style sealers are designed for embossed or channel bags and may not pull a vacuum on a smooth bag — check your sealer's manual, or order one pack and test before you commit a run. Without a vacuum, the bag still heat-seals on any impulse or band sealer.

The bag is sold as a general-purpose barrier bag. If you need documentation for direct food contact, ask us before you order and we will confirm what is available for this film.

Yes. Other sizes, zipper closures, gussets and custom-printed bags are quoted on request — send us the details or call +1 (833) 722-3456. Bags Etc also supplies pouches and bags, roll stock film and packaging machines for lines that fill and seal bags automatically.
