3.5g (1/8 oz) opaque mylar pouches with ASTM D3475-tested child-resistant zippers — printed in metro Detroit, compliant in CA, CO, MI, NY, IL, WA, MA, and other active state cannabis programs.
Brand My Bags makes custom-printed cannabis eighth bags — child-resistant, opaque mylar pouches sized to hold 3.5 grams (1/8 ounce) of cannabis flower, manufactured at our metro Detroit press.
Standard sizes are 3.5″ × 5″ flat-lay or 3.6″ × 5″ × 1.5″ gusseted, with a multi-layer MET-PET barrier that blocks UV light, oxygen, and odor at the film itself.
Every Brand My Bags cannabis eighth bag is constructed from a 3-layer MET-PET laminate: print-receptive PET outer, metallized MET-PET middle (350–450 angstroms of vacuum-deposited aluminum), and a food-safe polyethylene sealant inner. The metallized barrier blocks UV light, oxygen, moisture, and odor-causing volatile organic compounds at the film layer — preserving trichomes, cannabinoids, and the terpene profile that defines the strain.
The closure is an ASTM D3475-tested push-and-pull child-resistant zipper, sourced from suppliers that maintain compliance certificates for the federal CPSC test protocol in 16 CFR 1700.20. Heat-seal tops with tear notches and slider closures with safety latches are available as alternates per state preference.

Cross-link out to the rest of the cannabis catalog and the manufacturer-direct format options. Same press, same film stack, different SKU shape.
High-volume dispensaries pre-weigh and seal eighths into branded opaque pouches before the sale floor — eliminating scale time at the register and standardizing terpene-preserving conditions. A consistent eighth bag format with lot-specific label zones satisfies state traceability requirements at scale.
Best with: Heat-seal top + reclosable CR zipper · Matte opaque MET-PET · 3.5″ × 5″ flat-lay
Craft cultivators releasing a single-strain harvest in limited quantities use eighth packaging as the primary brand canvas — 17.5 sq inches of printable surface for terpene notes, genetics lineage, and harvest date at a unit cost that works for 100-unit boutique runs.
Best with: Soft-touch matte laminate · Spot UV on strain name · Tear notch · 100-unit MOQ
Hemp-derived CBD and CBG flower shipped DTC must meet state opaque and resealable rules where they apply, while differentiating clearly from THC products. An eighth bag with a clear window stripe on one face shows the product while keeping the package opaque on regulatory-mandated surfaces.
Best with: Partial clear window · Press-to-close CR zipper · Pre-designated compliance label zone
Three to five half-gram pre-rolls fit inside a standard 3.5″ × 5″ eighth bag, making the format work as a multi-unit pre-roll pack totaling 3.5 g. The flat-lay shape stacks efficiently in drawers and POS displays; the resealable zipper keeps unused pre-rolls fresh between sessions.
Best with: Opaque MET-PET · Press-and-squeeze CR zipper · No gusset · Hang-hole punch
Seasonal cannabis drops — first-harvest releases, anniversary strains, collaboration genetics — use premium eighth packaging as a collector piece. Hot-stamp foil or soft-touch matte with spot UV on a 3.5″ × 5″ pouch delivers shelf presence glass jars cannot match at equivalent run sizes.
Best with: Hot-stamp gold or silver foil · Soft-touch matte overlaminate · Serial / batch numbering
Multi-state operators standardize on a single eighth-bag dieline and adjust the label zone per state, letting one film SKU serve CA, CO, MI, NY, IL, WA, and MA markets — state-specific opacity, universal symbol placement, and language requirements handled in the print layer rather than the film structure.
Best with: All-opaque MET-PET · Pre-designated compliance zones · Resealable CR zipper
An eighth of cannabis equals 3.5 grams (one-eighth of an ounce) and is the single most-purchased quantity at US dispensaries — it represents a typical week of consumption for most adult-use customers and stays inside the single-purchase possession limits in nearly every state cannabis program.
A flat-lay cannabis eighth bag measures 3.5″ × 5″ (89mm × 127mm). The gusseted stand-up variant is 3.6″ × 5″ × 1.5″ gusset (92mm × 128mm × 38mm), with the expanded bottom accommodating 3.5g of loosely packed flower without overstuffing the zipper zone.
Yes. Cannabis eighth bags sold at retail must be tested to the federal CPSC protocol in 16 CFR 1700.20 — the rule that implements the Poison Prevention Packaging Act of 1970. Every US state with a regulated cannabis program has adopted that floor or stricter.
16 CFR 1700.20 is the federal CPSC test procedure for child-resistant packaging; ASTM D3475 is the ASTM International classification standard that categorizes CR packaging by closure type. They are related, not identical — a compliant cannabis eighth bag should reference both.
MET-PET (metallized polyester) film blocks the volatile organic compounds that carry cannabis odor at the film layer itself; the press-and-squeeze child-resistant zipper provides resealable odor containment when fully closed. A heat-sealed eighth pouch is functionally odor-impermeable until opened.
MET-PET (metallized polyester) is biaxially-oriented PET film with approximately 350–450 angstroms of aluminum vacuum-deposited onto its surface. The metallized layer blocks UV light entirely, gives oxygen transmission below 0.01 cc/100 in²/day, and contains odor-causing volatiles — the three forces that degrade cannabinoids and terpenes.
Alaska, Colorado, Florida, Hawaii, Maryland, Massachusetts, Michigan, Missouri, Montana, New Hampshire, New Mexico, Oklahoma, Oregon, Pennsylvania, South Dakota, and West Virginia mandate opaque cannabis packaging by regulation. California's rule prevents a child from reasonably inferring the contents are cannabis, which functionally requires opacity.
A cannabis exit bag is the opaque, child-resistant outer bag that dispensaries are required to provide at the point of sale in many states (Michigan, California, and Colorado among them). An eighth bag is the product's primary retail package — the exit bag is an additional outer layer.
Cannabis eighth bags built from MET-PET laminate are structurally reusable — the film does not degrade from repeated zipper actuation. Several state regulators and dispensary chains encourage reuse of exit-bag-format pouches as a sustainability practice; the child-resistant mechanism should still be inspected for wear before reuse.
Brand My Bags requires a minimum order of 100 units per SKU for custom-printed cannabis eighth bags on digital print runs — one of the lowest MOQs in the category, where most converters require 500–5,000 minimum. Offset and rotogravure runs typically start at 500 units to amortize plate or cylinder cost.
ASTM D3475-tested child-resistant pouches across every size and SKU — cannabis, pharma, and regulated consumer products.
Self-standing, billboard-front Mylar pouches with a gusseted bottom — the format that owns retail beyond the eighth.
Slim, mailer-efficient pouches without the gusset — ideal for sample sachets, single-serve, and DTC drops.
Cannabis packaging must balance compliance, freshness, and brand identity. How CR Mylar delivers all three for flower, edibles, and concentrates.
