A Guide to Pre-Roll Tubes - Accelerant Manufacturing

A pre-roll tube is a cylinder-shaped container to keep dry herbs or pre-rolls fresh and secure. They are also known as joint tubes or pop-top tubes, made using polypropylene or glass, although there are new, more eco-friendly options.

Why Are Pre-Roll Tubes Important?

Handling loose, dry herbs and easy-to-break joints poses a challenge and needs to have pre roll packaging.

Preserves the Freshness

A pre-roll tube is the best choice if you like rolling several joints or herbal cigarettes at once. It keeps them fresh and prevents them from getting too dry and burning too quickly.

Suppresses the Smell

Some dry herbs give off more smell than others, especially when you smoke half a joint at a time. To avoid this lingering smell, close the cap of the tube to drown the scent or make it undetectable.

Child-Proof

Kids tend to be curious, so it’s important to keep your merchandise out of reach. A joint tube makes it harder for kids to access the herbs, should they come across it.

Guarantees Discretion

Carrying an open-rolled joint or a half-smoked joint gives off a smell that attracts unnecessary attention. A Pre-roll tube enables you to take herbs anywhere you go, unnoticed.

Should Pre-Roll Tubes Be Child-Resistant?

Some state regulations require that weed packaging be child resistant. The child-resistant properties of pre-roll tubes depend on the tube and the lid mechanism.

According to ASTM D- standards, safety tests involve 100 children under the age of 5, with and without a demonstration. To pass, 85% of the children should not be able to open it without a demonstration, and 80% should not be able to open it with a demonstration.

The best cannabis pre-roll packaging has enough resistance to be child-proof, but soft enough to allow adults easy access.

Types of Pre-Roll Tubes

Pre-roll tubes vary in length; 90 mm, 98 mm, and 116 mm. The standard diameter for a single-joint pre-roll tube is 16mm, to allow the herbs to fit in the tube without feeling bulky in your pocket.

Pop-Top Pre-Roll Tubes

Polypropylene pre-roll tubes are most popular because they are very economical. The opening mechanism is almost similar, where you squeeze the sides of the tube near the top, and the lid opens with a popping sound.

Pop-top pre-rolls tubes are child-resistant, but it's essential to check the tube for certification (ASTM D- standards). The strength required to pop open the tube presents the child-proof aspect.

The tubes have a plug seal that prevents the majority of the smell and air from seeping out. Polypropylene is a good moisture barrier. Add a moisture pack inside the tube to enhance the freshness.

Super Seal & Gasket Seal Pre-Roll Tubes

The material used to make Super Seal pre-roll tubes is thick, heavy plastic. They have a push and turn style lid that requires you to push down on the lid while turning it and are airtight.

Standard tubes are easy to use for adults and child-resistant due to the strength you need to push and turn the cap.

The Super Seal tube has a tamper evident band that activates when the screw cap seals. It has a soft plastic insert on the inside of the lid, which creates an airtight and water-tight seal when the lid screws down.

To open the gasket pre-roll tubes, you’ll need to push the lid in and up. The child-resistant mechanism used is new, so you’ll find more instructions on how to open the package.

The gasket pre-roll tube has a plastic ring that provides a strong airtight seal and closes any gaps.

Glass Pre-Roll Tubes

Glass pre-roll tubes are often used for packaging infused pre-rolls or for that luxurious feel.

Some are child-resistant. Others are not, depending on the cap or top. Child resistant pre-roll tubes have a push and turn screw-top, while non-resistant ones have a cork top.

Screw Top Glass Pre-Roll Tubes

These have easy-to-use push and turn child-resistant lids. The lids have two variations; one has ridges and instructions on top, while the other is smooth.

The smooth one is simple and easy on the eyes, though others prefer having clear instructions on top of the lid. If you have trouble opening child-resistant containers, the ridges provide extra grip.

The Cork Top Glass Pre-Roll Tubes

They have a cork stopper that provides an airtight sealing mechanism.

Since they are not child-resistant, they are only allowed in some states. To comply with the child-resistance requirements, some brands insert the tubes into child-resistant bags or boxes.  Both are air and water-tight, but the cork has the tightest seal.

Ocean Plastic Tubes

The ocean plastic tubes are eco-friendly, made using recycled plastic collected from the ocean.

They are child-resistant and have an open mechanism that requires you to line up the lip of the lid to the dots on the container before you’re able to push it off.

How Do You Make Tamper Evident Pre-Roll Tubes?

A tamper evident mechanism reveals any kind of interference with the contents. In many states, regulations require cannabis products to be tamper-evident.

Pre-roll tubes are not tamper-evident on their own, forcing manufacturers to add said mechanisms. There are two main ways to achieve this; using tamper-evident shrink bands and using a paper sticker.

A tamper-evident shrink band is a small, clear plastic band that only goes around the lid or cap.  Its job is for labeling pre-roll tubes. It's shrunk, so the only way to open the container is by ripping it off.

A paper sticker goes over the cap and has to come off to open the lid. Any attempts to remove and reapply the sticker are vividly evident.

Some brands use plastic stickers instead of paper, which are not as effective. They’re easily removed and reapplied after accessing the container.

If you’re looking to go Pro, the performance Accelerant PRO (Pre-roll Operator) is the automated pre roll packaging machine you need.

There are no upfront costs, with a Pay-As-You-Produce plan as low as .08 per pre-roll. There are no maintenance costs, and you enjoy free upgrades. Schedule a demo to see it in action!

How to package, seal and label glass tubes effectively - A Guide

Dispensary and smoke shop owners are well aware of different types of cannabis packaging available in the market. Among all the options, glass tubes stand out as the best packaging option for prerolls and joints. Glass tubes are a popular cannabis packaging as they provide an aesthetically pleasing appearance and exceptional protection for prerolls and joints. They look sleek, elegant, and are unmissable! These glass beauties provide top-quality function, whether you’re using them for storage, transportation, or just display. 

Let’s look at how you can effectively package, seal and label glass tubes for your dispensary and smoke shop. 

Why Glass Tubes?

Glass tubes offer an elegant packaging solution for prerolls, cones, joints, and vape cartridges. They work well as a display piece and are a versatile packaging solution. They are clean materials to print on, and it is also easy to label them. Since glass is a low toxicity material, many food and beverage companies use glass for packaging their products. Not only this, but glass is also resistant to solvents, acids, oils and is comparatively durable.

Packaging using Glass Tubes

Loud Lock glass blunt tubes are made from BPA-free material and present a unique way to package prerolls effectively. They are favorites in both dispensaries and smoke shops. You can order varied sizes of glass tubes as per your requirement. As they are commonly called, doob tubes or preroll tubes are available in various sizes like 90 mm, 98 mm, 110 mm, 113 mm, 116 mm, 120 mm, and others. 

Using clean glass tubes is crucial to maintaining the quality of your cannabis product. If you are storing your preroll tubes in the production facility or nearby, the chances are that some flower dust might get settled on them or even inside them. It is crucial to blow off the tubes with compressed air before using them for packaging your prerolls. You can also wipe them down using isopropyl alcohol. This will give a sparkling clean look to your glass tubes and help the labels stick onto them without peeling off. 

Sealing Glass Tubes

A child-resistant screw-top cap is an excellent idea to seal your glass tubes. Loud Lock uses a child-resistant screw-top cap threaded especially for the cone and blunt tube vial container.

These caps provide an airtight seal and help maintain the freshness of the prerolls inside the tubes. The child-resistant caps also provide enhanced security for your customers on the go. Loud Lock blunt tubes are an exciting way of storing and displaying pre-rolled medication in your dispensary. They provide discreetness as they cover up the odor as well. Loud Lock Glass tubes are certified child-resistant and protect your cannabis throughout the process of storage and transportation.

Many other glass tubes come with a cork top or a child-resistant cap with a tamper-evident seal built in it. The cork stopper seals the tube well enough to preserve the freshness. It would be a good idea if the vials were shrink sealed further to avoid any contamination.

Labeling Glass Tubes

Purchase labels that are specifically designed for small circular tubes. A general label might not be as effective as the labels explicitly designed for glass tubes. For example, a label that sticks well on a flat surface might not be as effective on a tight, narrow glass tube. 

Another important consideration is the amount of product you want to show in your glass tube. It is crucial to compare the size of the label to the size of the preroll tube, in this case. If you wish to cover the visibility of your entire product, choose a label that you can wrap around the entire tube. However, if you want your prerolls to have some visibility, you can leave about an inch of space empty for that. 

It is important to note that labels must have all necessary information and branding information. It would be a good idea to go through the labeling regulations and guidelines for cannabis packaging in your State to meet the required compliance. 

After choosing the size of the label, you need to apply them to the glass tube. You can go manual and stick each label by yourself. But this can be quite a task as you scale your business and sell larger lots of prerolls. In such cases, you must consider automation. You can choose from manual, semi-automatic, to fully-automatic machines to implement a smooth preroll packaging process and label them. These machines can increase the overall volume of freshly labeled joint tubes by several notches. Not only are they efficient, but they also help you save a lot of labor costs and time. 

We hope that you have much more clarity about preroll glass tubes for your cannabis business by now.
