A critical element of packaging functionality, sealing is defined across several levels.
SELECT THE PROPER MATERIAL
First, the material selection. It is critical to select a nonporous material. If it is stating the obvious, it remains essential. When it comes to porosity, not all materials are created equal. Since 1833, the date of its creation, Tournaire has been an expert in metals. Today it offers solutions in both aluminum and stainless steel, two materials recognized for their exceptional barrier properties.
UN CERTIFICATION
This regulatory requirement for shipping hazardous materials is complex. It varies based on the mode of transportation, the product, the quantity, and whether you are shipping a liquid or a solid. The certification applies to the bottle and its closure system, which are tested using a specific torque. Using the proper torque is mandatory. It is imperative to follow the closure instructions. Our experts can guide you through the process.

FINE SEALING
Some products are sensitive to moisture or oxygen; others can be hazardous. In those instances, the integrity of the seal is scrutinized; this can be referred to as enhanced sealing. The quality of the seal has two main objectives: preventing the product or its vapors from escaping the bottle (leakage) and preventing the reverse, such as oxygen or moisture ingress. It is the mastery of the bottle-closure system that enables an enhanced sealing solution. Tournaire’s expertise, built through years of experience and testing, enables us to help you address seal-integrity challenges.
