Breyer GmbH has expanded its portfolio with two further complete lines of the Breyer TopLine product family. In addition to the systems for the tube production of single-layer and up to 5-layer layer construction, complete lines for up to 6 and 7 layers are now also available.
The development of the 6-layer tube supports the efforts of health & care manufacturers to further reduce or eliminate the use of additives (preservatives).A very thin, constant inner layer with an anti-bacterial effect reduces the use of preservatives. The tube is therefore suitable for allergy-friendly creams and other products. The protection of the contents and the durability are given by the interaction of the barrier and anti-bacterial layers.
In addition, the tube with 7-layer layer construction offers an "ULTRA HIGH" flexibility both in the production of the tube itself and in its usability.Whether 1-layer or 2, 3, 4, 5, 6, 7 layers, each individual product should be designed as individually as possible. Likewise, the protection of the contents was considered. The single-layer barrier (5-layer tube with EVOH as barrier layer) has limitations and can not be used for all filling goods. By increasing to 7 layers, it is now possible to "install" a double barrier.
Various combinations of materials are possible (for example EVOH / PA, EVOH / PVDF, EVOH / PETG). This enables the leap into the "ULTRA HIGH BARRIER" for extruded tube bodies.
A pure plastic tube is "non-collapsible" and recyclable. Standardized procedures allow the separation of the body from decoration residues (paints, printing inks) and different plastics. The cycle (raw material reuse) of a 7-layer plastic tube is thus comparable to that of a drinking bottle made of PET.
In this area too, the advantage of the "ULTRA HIGH" flexibility of the new 7-layer co-extrusion line comes into play. For less demanding products (barrier classification), the inner layers may also use PCR (post-consumer recycling) and / or biodegradable and / or bio-based material. The worldwide requirements for the prevention and reduction of plastic waste are thereby taken into account.
Furthermore, completely new materials (e.g., highly transparent) are possible without losing the barrier effect. (e.g., 5 layer barrier + 2 functional layers)In addition, it is possible to extrude the tube body thin-walled, and thus to achieve a material reduction of up to 40%. This reduces costs and helps save resources.
