Custom Mylar Bags Built for Cannabis Brands That Refuse to Compromise

I've been in packaging for 30 years. I've seen every shortcut, every flimsy import, every broker promising the moon and delivering bags that don't seal right. That's exactly why CropPak exists. We run our own factory floor. We control the film, the ink, the dies, and the quality checks from the moment raw material arrives to the second a pallet leaves our dock.

When you order custom mylar bags from CropPak, you're not submitting a request to a reseller who forwards it to someone overseas. You're talking to the operation that physically produces your packaging. That changes everything about how fast, how honest, and how good your experience is.

What Makes CropPak Mylar Different

Most custom mylar bags sold online come from one of three giant Asian converters. The broker lists a product, takes your artwork, forwards it, waits six weeks, and ships you a pallet. If the registration is off or the zip seal doesn't engage properly, you're stuck filing a claim with someone who doesn't actually make anything.

We don't work that way. Our bags are produced in our facility on equipment we maintain ourselves. We inspect every run. If a heat seal isn't hitting the right pull strength, we catch it before it ships. If a Pantone match is off by half a shade, we adjust the plates and rerun. You get the kind of quality control that only happens when the person answering your email can walk 40 feet and watch your bags come off the line.

That also means we can do things brokers can't. Need a CO2 vent added because your product off-gasses? Done. Need a custom die shape that isn't in any catalog? We'll cut it. Need 5,000 bags split across four sizes with the same artwork? No problem. When you control production, you control the options.

Why Multi-Layer Barrier Construction Matters

Mylar isn't one material. It's a brand name that became shorthand for metallized polyester film, and the bags people call "mylar" are actually multi-layer laminates. The quality of those layers determines whether your product stays fresh for two months or two weeks.

Our bags use a high-barrier construction that includes a polyester outer layer for print receptivity and structural strength, an aluminum metallized layer that blocks oxygen and light transmission to near-zero levels, and a food-grade inner sealant layer that bonds cleanly under heat. That stack is what protects terpene profiles, prevents oxidation, and keeps moisture where it belongs, outside the bag.

Cheap single-layer bags leak. They let light through, which degrades cannabinoids. They absorb odors instead of containing them. They lose seal integrity after handling because the layers aren't bonded properly. You save eight cents per bag and lose a customer who blames your brand for stale product. The math doesn't work.

Every CropPak bag meets FDA and USDA compliance standards for food-grade contact. The inner layers are tested for compatibility with cannabis flower, concentrates, edibles, and pre-roll products. We can provide documentation for compliance audits and dispensary verification programs.

Every Size Explained

Cannabis packaging isn't one-size-fits-all. You need the right bag for the right product, and choosing too large wastes material and looks sloppy, while choosing too small risks overfilling and seal failure. Here's the full size range we produce:

• 1g bags: Small pouches for single pre-roll packs or sample flower. Tight, compact, minimal headspace.
• 3.5g (eighth) bags: The most common flower bag. Fits a standard eighth with room for a humidity pack if needed.
• 7g (quarter) bags: For premium flower portions or multi-pack pre-roll sets.
• 14g (half ounce) bags: Larger format for bulk-conscious consumers or dispensary display stock.
• 28g (ounce) bags: Full ounce flower packaging. The workhorse size for many brands.
• 1 lb bags: Bulk packaging for wholesale, distribution, or processor-to-dispensary transfer.
• Custom sizes: If you need something between these sizes or entirely different, tell us the dimensions. We'll cut a die.

Each size is engineered with the appropriate seal width and material thickness for its volume. A 1g bag doesn't need the same construction as a 1 lb bag, and we adjust accordingly. That's not a luxury feature, it's just correct manufacturing.

The Finish Menu

Finish is what your customer touches before they open the bag. It sets the perceived value of your product before they ever see what's inside. We offer five finish options:

• Matte: Soft, non-reflective, premium feel. The finish most high-end cannabis brands choose because it photographs well and looks expensive on a dispensary shelf.
• Gloss: High shine, vivid color saturation. If your brand identity is bold and energetic, gloss makes your artwork pop under display lighting.
• Holographic: Prismatic effect that shifts with viewing angle. Eye-catching for promotional products or limited drops.
• Clear window: A transparent panel that lets customers see the product inside. Required by some state regulations and preferred by brands selling visual quality as a selling point.
• Kraft: Natural paper-look exterior with full barrier interior. For brands positioning around sustainability and earthy aesthetics.

You can mix finishes with print effects. A matte bag with a spot gloss logo is one of the most effective combinations in packaging design. The contrast reads as intentional and premium without being loud.

Print Effects and Customization

Printing on mylar is different from printing on paper. The metallized surface affects how ink colors read, and the lamination process means you need a printer who understands layer order, opacity, and how effects interact with barrier film. We handle all of this in-house.

Available print effects include:

• Foil stamping: Metallic foil applied with heat and pressure for gold, silver, copper, and holographic accents.
• Metallic inks: Ink mixed with metallic particles for a subtler shine than foil stamping. Good for large areas where full foil would be too expensive.
• Pantone matching: We match your specific Pantone color references so your bag matches the rest of your brand system.
• Spot UV: A high-gloss UV coating applied to specific areas of the design for contrast against a matte or gloss background.
• Hole punch: Retail hang-tab holes for dispensary pegboard display.
• CO2 vents: One-way gas release valves for products that off-gas, preventing bag inflation without compromising barrier integrity.

Compliance and Child-Resistant Certification

If you're selling cannabis in North America, child-resistant packaging isn't optional. We've been certifying CR bags since the regulations first dropped, and we know the standards cold.

Our child-resistant closures are certified to 16 CFR 1700.20, the federal standard for special packaging, and tested to ASTM D3475, the standard for child-resistant packaging performance. We maintain documentation for every CR product we manufacture, and we can provide compliance paperwork for your regulatory filings, dispensary onboarding, or state license applications.

We offer multiple CR closure types including press-to-close zippers that meet the standard, CR zip seals designed specifically for cannabis packaging compliance, and tear notch openings paired with CR inner layers for products that need dual access protection. Not every bag needs to be child-resistant, but when it does, you need to know the certification is real and current. Ours is.

The Factory-Direct Pricing Model

Here's how buying from CropPak works. You send your artwork, specs, and quantity. We calculate the actual production cost, add our margin, and send you one number. That number is the price. There are no line items for setup, no plate fees tacked on after you've approved the quote, no surprise freight charges.

When you buy from a broker, the quote you receive includes their markup plus the manufacturer's markup. You're paying two companies for one product. When you buy from CropPak, you're paying one company. The one that actually makes the bags.

Same-day quoting means you're not waiting a week to find out if the project is viable. Send specs in the morning, get a quote back by afternoon, approve artwork, and we start production. For repeat orders, we keep your plates and specs on file, so reordering takes minutes, not weeks.

Volume pricing scales honestly. The more you order, the less it costs per unit, because our efficiencies improve with larger runs. We pass that savings through. There's no game where the first price is artificially high so we can offer a "discount" later. The first price is the real price.

This is how packaging should work. Direct. Honest. Fast. Made by the people you're talking to.
