Roll-on Caps

Our roll-on caps provide you with the perfect means for administering precise doses of liquids, creams, gels or oils. Due to the soft surface of the rolling-boll which applies a thin layer of your topline products directly to the skin, it becomes the ideal cap for facial cosmetic creams, roll-on perfumes, deodorant or waxes, as well as hemp oils, aromatherapy products, essential oils and fragrances. Depending on your product line, MIRON Violetglass currently offers a choice of three different balls, namely: glass, plastic and steel balls. Next to that, you can choose between a natural or white fitment on the inside.

Let’s talk about threads

...But what exactly are threads?

Simply put, threads are the protruding lines curved around the neck of the bottle. They ensure that the matching closure will have a tight fit to protect your natural ingredients from being tampered with or from leakage. The threads size depends on the size of the bottle neck as well as our range of closures. Our bottles and jars as well as the corresponding closures must have matching threads. If in doubt, it is always advisable to contact the sales department.

DIN18

DIN is the industry standard for dropper bottles in Europe, and DIN18 is the German-based norm. It refers to the standard size of the neck, height and diameter. Roll-on caps with a DIN18 threaded closure go hand in hand with any Orion dropper bottle up to 100ml (3 ½- oz) that features the DIN18 thread and a tamper-evident transfer ring. The right choice to ensure product safety.

PP and UREA

PP is also known as polypropylene and falls under the plastic identification code number 5. The material is easily produced and has a high degree of purity. It comes with a range of benefits, so is it difficult to break, lightweight, easily and 100% recyclable. Due to its properties, PP is suitable for various applications, including food, cosmetic, and natural healing product packaging. Urea formaldehyde moldering material (UF) is also known as amino plastic. This type of material has become a common component of closure applications. The UF resins are noted for their high strength and rigidity.

Ball types

All roller balls are designed to disperse a small amount of a product’s content when you roll the ball across your skin. When looking at the different types, plastic roller balls are generally more affordable. Glass is often chosen because it does not react with essential oils or other mixtures contained in the packaging. And stainless steel tends to be more durable than their plastic alternative and maintains consistent quality for continued application. In addition, a stainless-steel roller ball is corrosion resistant and often used for perfumes or other liquids.

At MIRON Violetglass we ensure that our closures always fit the corresponding bottles and jars. However, it can sometimes be a bit of a challenge to find the right closure which complements the needs of your natural ingredients. We are always happy to answer any questions you may have and to become a part of your products journey.
