Custom Glass and Child Resistant Closures for Cannabis Packaging

Glass packaging has always been a popular choice for a wide range of products due to its versatility, durability, and aesthetic appeal. With the ability to withstand extreme temperatures, glass packaging can accommodate a range of processes such as hot filling, decorating, and curing. Additionally, glass is a highly inert substance that is infinitely recyclable, making it an eco-friendly option. In the world of cannabis packaging, borosilicate glass is often used for tubes, while soda lime silica glass is used for cannabis jars. These materials have been carefully selected for their ability to provide safe and secure packaging for cannabis products, while also maintaining the potency and freshness of the contents inside.

Decorating Options

Your glass containers and closures can be decorated with a wide range of colors and designs. We can match PMS colors, matte or glossy coatings, metallize and more to meet your requirements. Our decoration options include:
  • Direct Printing on jars and lids: Applied Ceramic Labeling (ACL) is a technique where the inks are applied by screen and then baked on the jars for a high-end look. This process does come with some printing constraints such as a gap of approximately 2mm between different colors.
  • UV Printing: This process is done with modern printers and cured with light, allowing for complex designs.
  • Heat Transfer Label: A specialized label is created, applied, and baked onto the jar, giving the appearance of a direct print. This process can allow for particularly intricate designs.
  • Dipping or Spraying with Solid Colors: Jars can be coated with a solid color and then printed over for a unique look.
  • Hot Stamping: Bright metallics can be added to the jars or closures using this option, especially over black.
  • Water Transfer Printing: A method that allows for highly colorful and intricate designs, such as tie dyes, wood patterns, and more. This option can be applied to both jars and closures and is best for randomizable patterns.
