Measuring 11.6 inches by 17.6 inches with an expanding bottom gusset, 1 lb Mylar pound bags hold 454 grams of dense cured dry flower. Multi-layer foil barrier laminates prevent trichome crushing during bulk storage while isolating strong botanical aromas within wholesale storage vaults.

• 1 Pound Capacity (16 oz / 454g): Engineered for high-volume harvest storage, wholesale distribution, and dispensary vault inventory.
• 11.6" x 17.6" Footprint: Provides ample internal volume to store full-pound flower loads without over-compressing delicate bud structures.
• Heavy-Duty Expandable Gusset: Stands upright when loaded to maximize shelf layout density and ease manual loading.

Pushing the thumb tab into the internal track mechanism unlocks the press-to-close zipper, satisfying Title 16 CFR 1700.20 and ASTM D3475 child resistance standards. The dual-action opening sequence stops unauthorized child access while allowing commercial processing teams to re-seal bulk inventory repeatedly without track degradation.

Constructed with an internal metalized aluminum foil layer sandwiched between PET and PE film, opaque Mylar pound bags achieve zero oxygen and moisture vapor transmission rates. Eliminating air permeability prevents delicate aromatic terpenes from evaporating, preserving strain scent profiles, humidity levels, and cannabinoid potency during long-term warehouse storage.

Opaque black and white exterior film layers block 100% of ambient light exposure, eliminating UV degradation of cured flower during extended bulk storage runs.

Applying direct heat between 320 degrees F and 375 degrees F across the top header welds the internal polyethylene film layers into a hermetic barrier. Integrated tear notches positioned directly below the thermal seal line allow dispensary operators to open bulk pouches cleanly while maintaining tamper-evident security during transit.
