Ranging from 2.8 x 7.5 inch narrow pouches up to 7.5 x 5 inch exit bags, pre-roll barrier bags accommodate single 84mm cones, 116mm king-size joints, multi-packs, and disposable vape hardware. Multi-layer foil and PET laminates keep paper seams flat while locking in volatile terpenes to maintain product freshness across retail shelves.

• 2.8 x 7.5 Inch Pouches: Formatted for single or dual 116mm king-size pre-rolls and slim disposable vape pens.
• 4 x 5 & 3.25 x 3.75 Inch Bags: Sized for compact multi-packs, dogwalker cones, or 510 cartridge hardware.
• 7.5 x 5 Inch Stash Locker Exit Bags: Designed to house multiple doob tubes, rigid joint boxes, or full dispensary customer orders.

Depressing the concealed thumb tab while pulling the press-to-close zipper track releases the locking mechanism, satisfying Title 16 CFR 1700.20 and ASTM D3475 child resistance standards. This two-motion opening sequence effectively prevents child access while allowing dispensary consumers to re-seal single-use or multi-pack pre-roll inventory repeatedly without track fatigue.

Laminating polyethylene terephthalate (PET) and aluminum foil layers to an inner sealant film yields a high-barrier structure with zero oxygen and moisture vapor transmission rates. Eliminating atmospheric air exchange stops volatile monoterpenes from evaporating, protecting pre-roll moisture content, strain scent profiles, and cannabinoid potency during long-term warehouse storage.

Full opacity across black, white, and metallized foil layers provides 100% UV protection, preventing light-induced THC breakdown when stock sits on dispensary display shelves. For a complete technical breakdown of film structures, review our Architecture of the Pouch Guide.

Impulse heat sealers operating between 300 degrees F and 350 degrees F fuse the internal linear low-density polyethylene (LLDPE) seal layer above the zipper to form a hermetic barrier. Thermal welding verifies tamper evidence for retail compliance, while laser-scored tear notches located above the seal allow operators and consumers to open pouches cleanly without tools.

Flat-pack Mylar pouches lay completely flat inside master corrugated cartons, packing thousands of units per box to minimize bulk LTL shipping costs. Lightweight foil laminates dramatically reduce gross freight tare weight compared to rigid plastic tubes or glass jars, lowering per-unit inbound transit expenses for commercial packaging facilities.
