    Early 80s

    MGJ launches its double seal with cardboard backing+ glued foil membrane TWINSEAL®

    THE TECHNOLOGY

    MGJ developed a temporary wax-based assembly technology, offering capsule manufacturers a two-piece seal consisting of a cardboard backing (acting as secondary seal once the container is opened) and an aluminum foil glued for tamper evidence… And the brand TWINSEAL® was born! The first clients to be interested in this highly innovative process would be instant coffee producers.

2010

MGJ starts its Z'TAB® partnership with Nestlé

NESTLÉ

The Nestlé Group was MGJ’s first client and strategic partner to invest extensively in the use of Z’TAB® for its Nescafé® brand. This partnership began during the early stages of Research & Development and didn’t stop until the large-scale market launch of Nescafé products in Europe. The Nestlé Group, committed to meeting consumer expectations and optimizing its industrial processes, has always incited and adopted the technological breakthroughs proposed by MGJ.

2007

MGJ patents Z’TAB

THE BENCHMARK

In order to better meet the expectations of its clients in all major markets: Pharmaceuticals, Cosmetics, chemicals, and the Food Industry, MGJ continued to innovate, launching Z’TAB®. Z’TAB® is a two-piece’ induction seal liner that is easy-to-peel thanks to its integrated grip tab. Z’TAB® is a worldwide unique sealing solution, patented by MGJ, which offers consumers 3 essential advantages: a tamper proof seal (tamper evidence on opening and first use), a secondary seal (better conservation of packaged products) and easy peel foil (guaranteed to be easy-to-open by any consumers aged 7 to 77!).

2000

MGJ launches its range of induction heat-seal liners

THE TECHNOLOGY

MGJ launched a major innovation with its induction heat seal liners. It was a small technological revolution spearheaded by MGJ, with the support of several major international Groups, especially the Food industry. Seal liners ensure a clean, perfect hermetic seal without any leakage, and help optimize packaging lines and product conservation. Moreover, heat-sealing machines only require a modest investment compared to other systems, such as conduction sealing. MGJ launched its new brand CORESEAL®, a technological revolution, now extensively adopted by all Industries, and which continues to be an unwavering success!

1995

MGJ innove avec la mousse en polyéthylène expansé en remplacement du carton

THE INVESTMENT

Face au succès rencontré par le TWINSEAL®, MGJ augmente ses capacités de production et enrichit son offre avec un support en polyéthylène expansé. Ce procédé améliore l’étanchéité secondaire du support et la propreté du système, sans résidus ni poussières. MGJ fait également évoluer la technique d’assemblage support / membrane, en développant un film extrudé en lieu et place de la cire.
