The value of the single-dose format

Controlled

Quantity defined according to the product’s function

Protected
formula

Materials selected for formula
compatibility

Simple

Opening and application designed for the final use

Beauty
On-the-go

Lightweight, compact formats that are easy to carry

Premium perception

Solutions designed to enhance high-positioning products

The single-dose format brings together formula, function and usage gesture in a protected, precise and easily distributable format.
It is an effective solution for product trial, simplified dosing, kit creation, step-by-step routines or more practical use away from home.

Every detail affects the final performance: opening, dispensed quantity, formula protection, material resistance, ease of application and pack perception.
For this reason, the choice of format must start from the product itself and from its real conditions of use.

A production hub dedicated to single-dose formats

Within OPAC Group, a specialised production hub brings together dedicated expertise in the filling and packaging of single-dose formats.
The organisation makes it possible to manage both complete projects and specific third-party packaging activities, with a focus on quality, flexibility and production scalability.

Technical expertise in the format enables support for the customer in choosing the solution most consistent with the formula, dose, materials, opening method, secondary packaging and intended use.

Formats

The right format starts from the formula, dose and usage experience

The choice of a single-dose format does not depend only on the filling volume.
Each format must be assessed in relation to the nature of the formula, the quantity to be dispensed and the way the product will be used by the consumer or professional operator.

A cream, a powder, a liquid or a moist tissue requires different materials, sizes and opening methods.
Likewise, a product intended for sampling has different requirements from a premium routine, a two-step treatment or a multi-use travel format.
