Quarter Mylar bags hold 7 grams of dried flower or 1/8 oz to 1/4 oz (3.5g to 7g) of medium-density buds without trichome compression. Formatted with bottom gussets and wide-mouth openings, these barrier pouches accommodate chunky strain profiles while maintaining internal headspace for heat-sealing operations above the zipper track.

• Opaque & Metallic Pouches: Standard 100% light-blocking foil laminates for strict state compliance and UV protection.
• Clear Front & Vertical Window Bags: Allows direct product inspection of flower structure while keeping back and side barriers lightproof.
• Wide Mouth Formats: Expands top entry width for rapid manual bin scooping or automated vibratory weigh-head filling.
• Novelty & Themed Print Packs: Pre-printed graphic runs including Tie Dye, Cali Flower, and Clear Leaf stock designs.

Opening child-resistant quarter bags requires depressing the concealed inner thumb tab while pulling the press-to-close zipper track open along opposing lateral vectors. This mandatory two-point mechanical release prevents child access under Title 16 CFR 1700.20 and ASTM D3475 standards while giving adult consumers repeated access without zipper track separation or seal fatigue.

Laminating oriented PET film, aluminum foil, and an internal LLDPE sealant layer yields a zero-MVTR (Moisture Vapor Transmission Rate) barrier sheet. Blocking atmospheric oxygen ingress stops oxidation of volatile monoterpenes and cannabinoid degradation, holding relative humidity stable inside the pouch to keep flower from drying out or developing mold during extended warehouse storage.

Direct impulse heat sealers set between 300 degrees F and 350 degrees F weld the internal LLDPE liner above the zipper track in 1.5 to 2.5 seconds of jaw dwell time. Thermal welding verifies tamper evidence for retail dispensary compliance, while integrated laser-scored tear notches positioned above the weld line allow consumers to open the pouch cleanly without scissors or blades.

Facilities looking to elevate branding can order fully custom-printed multi-layer films via our Custom Printed Wholesale Mylar Bags Page or explore automated labeling using our In-House Label Application Service Page.

Empty quarter pouches lay flat in master corrugated cases, fitting up to 5,000 units per carton to maximize cubic pallet density. The ultra-lightweight foil construction minimizes gross freight tare weight compared to rigid glass flower jars or thick plastic tubs, driving down inbound LTL freight costs per unit for commercial packaging facilities.
