In 1979, Jean-Marie Martineau, a self-taught businessman, created a company to manufacture flexible packaging, in particular in polyethylene bags for industrial usage.

Accompanied by his sons Eric, in charge of commercial development, and Benoît managing the production, Jean-Marie acquired small premises in Saint-Pryvé-Saint-Mesmin, near Orléans.

Driven by the energy and vision of the Martineau family, Valembal grew and in 1984 moved to new premises more suitable for its expanding industrial production.

Growth really took off in 1989 with the creation of a thermal bag of isosceles shape which was an immediate success with large retailers in France and Europe and later in America.

Two successive relocations enabled the company to develop further with a larger workforce becoming increasingly experienced and professional over time in the harmonious atmosphere of a family-run business.

With a prime objective of customer satisfaction, Valembal has always pursued a policy of continuous improvement and has regularly invested in the high-tech machines necessary to express its creativity.

More recently it has increased its efforts to be an eco-friendly company, notably by reducing its carbon footprint.
