Public Health of Cannabis Packaging

As more and more states welcome recreational marijuana use, the regulations surrounding its growth, transfer, and commerce are being developed as well.

In the state of Oregon, public health officials and politicians have an interest in making sure marijuana is used in the safest way possible, and to keep it out of the hands of the under 21 crowd.

The state also wants to discourage folks from driving under the influence and to warn them that the effects of certain types of marijuana (particularly edibles) may not be felt for 2 or more hours. They also aim to direct buyers in the proper use, hence informing customers of the amounts of THC in each product, which products to eat (or not eat), etc.

What is Mylar?

Mylar’s Origin & History

When Mylar was developed in the 1950’s it is doubtful that the inventors realized that Mylar would one day be a very important material for the recreational and medical cannabis industry. Mylar was developed to be a superior alternative cellophane and quickly replaced cellophane. Mylar has been used in many applications including by NASA. for space suits and in experimental balloons Mylar is technically a BoPET plastics, which is basically a specially designed polyester. Marijuana and cannabis packaging is only one of the uses for Mylar, it is used in many applications because of its unique barrier properties.

Mylar as a Barrier Packaging Solution

Mylar can be combined with other materials to produce packaging with very special characteristics.

  • Heat Resistance
  • Smell and Odor Proofing
  • Moisture control
  • Durability

Mylar is Great For Weed Packaging

Economical: Mylar bags are more economical that plastic vials.

Moisture Control For Edibles: Mylar prevents the transmission of moisture into and out of the bag. Moisture Transmission is very important for edibles.

More Child Resistant: Mylar bags have many child resistant features. Unlike cheaper bags, it is harder for children to rip or tear Mylar especially when combined with Nylon.

Common Questions about Mylar Bags

  • What Color is Mylar, is it silver? No actually Mylar is not silver, Mylar is translucent. Mylar can be coated with a metalized film to make it appear silver. Mylar films come in many colors including white, black, silver, gold. blue, clear, brown, and other custom colors.
  • Why do Mylar bags extend shelf life? Mylar slows and prevents the migration of oxygen and moisture through the bag, then control prevents things from drying out or getting soggy, which ensures peak freshness.
  • Is Mylar safe? Properly sourced Mylar is very safe for food and doesn’t pose a health risk.
  • Can You Print On A Mylar bag? Yes, you can print on a Mylar bag.

Example of the Common Technical Specifications of Mylar Films

Mylar / Nylon films used in packaging are listed below. The exact specifications of any particular bag will vary, and is based on the exact ratios of plastics used in the bag.

Oxygen Transmission Rate (OTR): 9.0 (ASTM-1434-66)
Moisture Vapor Transmission Rate (MVTR): .3 Mocon
Burst: 55 PSI
Puncture: 10 Lbs (Fed. TM 2065)
Tensile MD: 18 (ASTM D-882)
Tensile XMD: 21 (ASTM D-882)

Grumpy Cat, She Gets It

Grumpy Cat Knows

As a marijuana entrepreneur, you probably feel as though you’re juggling so many things at once. From growing or processing the bud, hiring new employees, maintaining your website, marketing, payroll, bills, putting out fires (figuratively speaking of course), it just never ends!

This is especially true in the MJ industry—it’s still the Wild West in many ways. Each state has different rules and regulations regarding medicinal and/or recreational use. Then you’ve got confusing and differing rules for child safety packaging. There are guidelines for how you collect sales tax. In many cities, dispensaries struggle to even remain open because city councils close them down. Let’s face it, this industry is not for the faint of heart.

So when it comes to packaging your buds or edibles, you need to work with a vendor who provides the following benefits:

  • Sells quality
  • Who won’t break the bank
  • Can ship it to you fast so you can package it, seal it, and sell it.

Below is proof that C4M can give you those benefits better than anyone else:

  • Quality: all of our bags are made with the highest-quality nylon laminates, here in California. Specific features:
    • FDA Food Grade Approved
    • Kosher
    • BPA, TSE Sulfer & Pthalates Free
    • American Made
    • Reach and Roho Certified
    • CA Toxins in Packaging Compliant
    • 3/8th inch Seams (prevents blow-out and tearing)
    • Smell Proof
    • Moisture control to maintain peak freshness.
  • $$$: The more you order, the more money you save. Even more generous price breaks kick in on quantities over 5,000.
  • Zoom Zoom: all of our stock items can be shipped within 48 hours of an order being placed. You can pick from a variety of shipping choices depending on how quickly you need the order. All of our bags are seal-able (we recommend impulse sealers).

Please let us know how we can help you reduce that cat-herding feeling. We talk about packaging every day. Call us at 626-376-9836.

Welcome to Oregon…Recreational Marijuana Coming Soon!

Land of the rose and sunshine, Land of the summer’s breeze;
Laden with health and vigor, Fresh from the western seas.
Blest by the blood of martyrs, Land of the setting sun;
Hail to thee, Land of Promise, My Oregon.

Oregon, My Oregon
J.A. Buchanan


What you need to know about recreational marijuana in Oregon.

In November 2014, Oregon voters, through a ballot initiative Measure 91, said yes to legalizing recreational marijuana. Now in less than 30 days, on July 1st 2015, Measure 91 will be implemented by the Oregon Liquor Control Commission (OLCC).

Woo hoo, it’s a free for all!

Not so fast, guys and gals. Starting July 1st, Measure 91 will afford Oregonains the following rights:

  • Grow up to four plants on their property
  • Possess up to 8 ounces of usable marijuana in their homes
  • Possess up to 1 ounce on their person in public

Important to note: recreational marijuana cannot be sold or smoked in public. Legal age for consumption of recreational marijuana is 21.

But I thought….

Oregon is trying to responsibly implement the new law. Therefore, applications for recreational licenses will be available January 2016 for commercial growers, processors, wholesalers, and retailers. Recreational marijuana is expected to “go live” on a state-wide scale closer to the fall of 2016. There will be special rules for edibles and extracts in the recreational sector as well.

No effect on Medical Marijuana Market

The current MMJ program in Oregon still remains, whereby Oregonians can apply for a medical card to be able to purchase marijuana (and related THC products such as edibles) at select dispensaries.

For the most up to date information from the OLCC, please check here:

Home Growers Still Need Bags

Are you ready to grow at home for your personal consumption? Containers 4 Marijuana carries a wide variety of products which can help you during the curing stage as well as storage of your new crop. All of our bags offer a strong barrier to oxygen and moisture, which prevents your buds from drying out. So keep your buds “laden with health and vigor” as long as possible with our awesome pouches and bags!

Packaging 101: Start Thinking of it as A Marketing Tool

When you are a grower or edibles producer, you are probably swamped in the day-to-day details of the business. It’s all about growing and harvesting the bud. If you are an edibles maker, it’s about creating new recipes and trying new flavors which your customers may enjoy.

Packaging your product can easily become an afterthought, a last-minute rush decision—just send me something that will fit my products so I can get them on the shelves. Sound familiar?

At C4M, we talk to people every day who need to get bags delivered not in a few days or a week, but business owners who really needed to place an order a few weeks ago. Now they’re under the gun. Packaging is just not a high priority for most folks, no pun intended.

One way to alter your view of packaging is not to see it as a last-minute, boring but important detail, but as a critical element of your overall marketing program. When you place packaging in the marketing area, rather than the “last-minute who cares” area, customers will notice, which can lead to increased business for you.

Keeping Weed Fresh: What is MVTR

Barrier Bag
Our barrier bags are made of a special combination of materials to control moisture.

What is a Moisture Vapor Transmission Rate?  And Why Should I Care?

So you started your marijuana business and things are really starting to pick up.  You’ve decided to start packaging your edibles/shake/buds etc. and every time you try and replace your turkey bag you keep hearing about barrier packaging and moisture and oxygen transmission rates.  Seriously, what the heck is that? And why should you care?  The answer has to do with the quality of your product and the shelf life while it’s sitting in a bag.  Basically, how long will the product last sitting on a shelf and how long can your end use customer enjoy it before it gets dried out and stale.

The Angel’s Share: Lost Moisture = Lost $

In the world of whiskey there is the idea of the Angel’s share, it is the alcohol that evaporates as the whiskey is aged in casks. Well unfortunately the same angel likes her weed too! The more weed dries out the less it weights. That weed you bought for resale will continue to loose moisture and weigh less if you do not keep it in a moisture controlled package. Also when moisture migrates into a product it can affect the taste, texture and overall quality. Some products, like weed buds, you want to keep the moisture inside of the package so that it maintains its freshness and weight.

Barrier packaging prevents weed from continuing to dry out and loose weight!

Dry and Stale Edibles Suck

For other products, such as dry edibles like cookies, granola or brownies, you want to keep the moisture content stable, but it is equally important to keep moisture out of the package so that it maintains its freshness and does not mold.  Moisture can either be the friend or enemy of your product depending on what is being packaged.

Moisture Vapor Transmission Rate (MVTR)

That’s where barrier packaging comes in.  When evaluating a packaging material the “Moisture Vapor Transmission Rate” (MVTR) is the measure of how easily moisture can penetrate the packaging film.  The higher the MVTR value, the greater the penetration rate (i.e. the faster moisture can get into or out of a package), and the lower the MVTR the stronger the ability of a package to keep dry goods like cookies moist (because it’s not letting additional moisture into the package) and moist products like buds moist (because its keeping the moisture that already exist in the product inside the package).

There are all sorts of factors that can affect the moisture transmission into a package, everything from the thickness of a material to the coatings used on the film.  Luckily for you, Containers4Marijuana are the foremost packaging experts for the marijuana industry.  We are here to help guide you to a package that will keep your product as fresh as the day it left your farm, grow house, bakery or dispensary.

Moisture transmission often needs to be balanced with Oxygen Transmission Rate (OTR) in order to provide the best barrier solution for a product’s needs.  Come back for our next blog post where we explore the wonderful world of oxygen permeability (or rather what makes shit stale) and why you shouldn’t plan any trips to Mars.

All our barrier bags and pouches for cannabis control moisture transmission.

A Federal End to the Prohibition of Marijuana

Exciting times for those who support the legalization of marijuana here in America. Two separate congressmen filed house bills this past Friday that if passed would take Marijuana off the controlled substances act and tax it. This would also transfer all power of regulation of the plant to the bureau of alcohol, tobacco, firearms and explosives.

Although these bills would legalize Marijuana on a federal level it would not force the legalization upon individual states. Each state will still have the right to vote on the subject and if they choose to legalize, the federal government would then be able to help regulate marijuana and its taxes in the state.

Jamaica Begins Changing its Stance on Marijuana

In Jamaica on 01/23/15 a bill to amend the dangerous drugs act was laid on the table by their minister of justice senator Mark Golding. This amendment was passed only weeks later on 02/06/15, a date in which I’d like to think deliberately passed it on because its Bob Marley’s birthday. It’s no secret Bob Marley was against the political oppression of Marijuana, and this amendment takes the country one step closer to decriminalizing the herb.

The amendment reduces the penalties of 2 ounces or less of cannabis to only a ticket and no mark on the criminal record, it also allows for the cultivation of up to five plants. Under the current law possession of cannabis can lead to not only a fine but also up to five years of prison time. The act of smoking marijuana for spiritual purposes is now protected under the amendment, which is great news for Rastafarians. Also accredited institutions can perform scientific research on the plant as well as medical cannabis can be prescribed by health professionals for different illnesses.

The bill also allocated provisions for the creation of a cannabis licensing authority to regulate medicinal marijuana and hemp industries in Jamaica.
Marijuana still remains a public health concern for government officials but those that still oppose these steps have resigned to the fact that this bill was a long time coming and even though the bill has yet to get past the countries House of Representatives it is expected to pass.
