This paper tube is designed as a secondary packaging solution for child-resistant glass jars. Instead of adding another CR mechanism, it focuses on protection, structure stability, and full-surface branding — making it a practical choice for brands that already use certified CR containers.
Used widely for cannabis flower jars, edible jars, and CBD products, especially when brands want a more premium and sustainable outer packaging.
Paper tubes used for glass jars are typically built with a rigid spiral-wound structure, designed to provide compression strength and impact resistance. Depending on the opening style and product positioning, there are several common configurations:
Two-piece tube (lid + base) — the most common structure, easy to open, practical for retail display and daily use.
Telescopic tube — suitable when you want a tighter fit or need more flexibility in height adjustment.
Shoulder tube — a cleaner and more refined structure, often used for more premium packaging programs.
For glass jars, the inner diameter and the fit between the jar and the tube matter a lot. A loose fit may look fine on screen, but in real shipping it increases the risk of movement, collision, and breakage.
This type of packaging is usually made from layered paperboard wrapped under pressure to form a rigid cylindrical body. Compared with folding cartons, the structure is stronger and better suited for protecting fragile glass containers.
Outer wrap: printed art paper for full custom branding
Core layer: kraft paper or greyboard for strength and compression resistance
Inner liner: white paper or kraft finish depending on the desired look
The tube can be fully printed, which means the brand has more room for color, pattern, finish, and shelf presentation than a plain stock container. Common finishing options include matte lamination, soft-touch, foil stamping, and embossing.
This structure makes the most sense when the glass jar itself is already child resistant, and the outer packaging is being used for protection, presentation, and branding.
When the primary container already meets child-resistant requirements
When the brand wants a more premium outer packaging than a standard folding carton
When a fully printable paper surface is preferred for stronger visual branding
When the product is positioned as a mid- to high-end item and packaging is part of the shelf appeal
When the goal is to reduce plastic use and move toward more eco-friendly materials
In practice, this type of tube is often considered by brands that want the jar to feel more giftable, more protected, and more finished at retail.
If the inner jar is not child resistant and the compliance requirement still needs to be solved by the outer packaging
If the project is extremely cost-driven and the lowest possible unit price is the only priority
If shipping efficiency is the main concern, since tubes usually take more space than flat-folding cartons
In those situations, other structures such as folding cartons or different secondary packaging options may be more practical.
For glass jars, the inside fit is just as important as the outer tube itself. If the jar is too loose inside, the packaging may still look premium but fail during transport.
Paper insert — a more eco-friendly option, suitable when sustainability is part of the brand story
EVA or foam insert — better cushioning for heavier or more fragile jars
Custom die-cut fitment — useful when the jar shape is special or when presentation needs to feel tighter and cleaner
