Single and double chamber resealable sample packs: the revolution

On the Sériplast stand at the PCD Paris show in January, there were two major new products: two variantes of the company’s flagship product developed in 2008 with the famous polypropylene split ampoule.

This time it is a resealable sample pack with a capacity of 1.5 ml and a double-chamber sample pack, also resealable, with a capacity of 1.2 ml. This packaging has been specially developed for CLARINS, for which an AWARD innovation dossier has been submitted for the PCD Paris 2025. In both cases, the challenge is always the same: to find a perfect breakability that allows the head and body of the ampoule to be separated and, despite the thinness of the wall, avoids any risk of leakage, while at the same time, and this is new, also ensures perfect resealability.

Mini gloss, mini mascara, mini dropper... variations are endless.

The main advantage offered by this resealability is the possibility of offering a head fitted with a gloss-type stem, a spatula, or a dropper.
It is very easy to use: simply break off the head of the ampoule.
In the case of a double-chamber ampoule, pour the product into the palm of your hand and close the ampoule by snapping the head back on when there is still product inside. The central skirt of the head keeps compartment 1 completely sealed from compartment 2.
In the case of an ampoule with integrated stems, use it according to its specific application (lip gloss, serum, mascara, cream,...), and afterwards, close the ampoule by snapping the head for future use.
There too, each ampoule is individually tested, and the trick lies in the design of the «in-house» tool moulds.
This range of innovative, adaptable packs called «Signature» is available in 3 formats: 1.5 ml, 3 ml, and 5 ml. Thanks to a choice of different applicators (dropper, spatula, brush, or fine brush) each product offers a personalised application, guaranteeing an optimal user experience.
As well as being practical and attractive, the «Signature» range is eco-designed (mono-material). It is also recyclable and sustainable, meeting the growing demand for a reduced environmental footprint while guaranteeing quality and practicality.
