Description
1. Laminated containers using SELAR? RB technology
The Du Pont trademark SELAR? covers a whole range of different barrier resins. Some of these are used as barrier layers in a coextrusion process, while others are formed as monostructures by injection or blow molding. SELAR® RB is one resin in this range.
RB is the abbreviation for "resin blend", which describes the concept of a barrier material produced by the single-hopper processing technique. Numerous overlapping platelets – or rather layers – of polyamide are distributed over the entire wall of the container by means of special extruder tooling and careful monitoring of the extrusion process. These overlapping polyamide layers reduce the permeability of the container wall by extending the path taken by any molecule migrating (permeating) through it.

SELAR® RB consists of a two-component mixture: the actual barrier resin itself (polyamide or ethylene vinyl alcohol) and a suitable coupling agent. SELAR® RB can be further blended with the polyolefin HDPE (high density polyethylene) and then processed in conventional extrusion blow molding systems. As it is a mixture of granular materials, the concentration of SELAR® RB can be varied and its barrier properties thus adjusted to meet specific requirements. The finished container retains the excellent physical properties of the polyolefin matrix.
With favorable processing conditions and the appropriate concentration of SELAR® RB, its barrier properties can be up to 100 times more effective against nonpolar hydrocarbons such as pure HDPE.

Plastomatic manufactures laminated containers under the brand name BARITAINER®.
2. Fields of application for BARITAINER® packaging
BARITAINER® packaging can be used for products containing solvents, such as household and industrial chemicals, cleaning agents and adhesives, as well as for flavors and fragrances in the food and cosmetics industries, additives in the automotive sector, photochemicals and agrochemicals, etc.
BARITAINER® packaging is therefore an attractive and also environmentally sound alternative to glass and metal containers. It can also replace coextruded or fluorinated containers and other materials with single-layer barriers such as Barex, polyester and PVC.
BARITAINER® products are lightweight and handy in use and can be manufactured in a variety of complex shapes.

3. Environment/end-of-life disposal
SELAR RB® is a safe, nontoxic and noncorrosive polymer.
This means that it is not only safe for the user but also does not cause any pollution when it is manufactured or when BARITAINER® packaging is eventually disposed of.
SELAR® RB is compatible with food products.

5. Identification
All our BARITAINER® products are marked with the Baritainer® logo embossed in the blow mold (see photo) in addition to other identification markings such as the UN No., part code, manufacturer's designation and the time (production date).The marking also serves as our seal of quality for this special container.
Only containers marked in this way are genuine BARITAINER® products from Plastomatic AG in Muttenz, Switzerland!
6. Developments
SELAR RB® technology can be used for all Plastomatic standard containers.
Plastomatic also creates customized BARITAINER® laminated containers in volumes from 3 to 200 liters.
* See the General description pages for examples of the markings on Plastomatic containers and drums. Other markings, in particular customer-specific designations, are available on request.
