Why Large Mylar?

  • Bulk-friendly capacities: 1–5 gallon formats fit family packs, emergency kits, and wholesale fills.
  • Durable protection: thick PET/AL/PE or PET/VMPET/PE laminations help block light, moisture, and oxygen.
  • Built for handling: side gussets and reinforced seals support heavy fills; add valves, zips, and tear notches as needed.

FAQs

What thickness do you recommend for 5-gallon bags?

We typically suggest 5–7 mil structures for heavy fills or long storage. We’ll spec material based on your product weight and handling.

Can large bags include a zipper?

Yes. We offer heavy-duty press-to-close (single or double track) and can add a heat-seal area above the zipper for tamper evidence.

Do you support oxygen absorbers or valves?

Yes. Our films are compatible with common oxygen absorbers, and we can add one-way degassing valves for coffee and off-gassing items.

What’s the MOQ and typical turnaround?

Standard MOQ starts at 100–500 units depending on size and print. Typical lead time is 10–14 business days after artwork approval with nationwide U.S. shipping.
