BIOTECHNOLOGY

The biotechnology sector is one of the application areas where continuous and frequent developments result in higher material requirements.

Today, flexible polymer single-use systems are replacing traditional glass and stainless steel in applications like meida storage bags, bioreactors, mixing vessels, product storage and sampling containers. These disposable pre-sterilised systems are increasingly considered a safer and less costly alternative to stainless steel equipment. This trend in the biotechnology industry is supported by exciting new developments in the polymer components of such flexible disposable systems, These components have to fulfil the strict product requirements of critical biotechnology and pharmaceutical applications.

In these fields, RENOLIT Healthcare is one of the leading suppliers of packaging materials for the most critical applications. After the introduction in the 1990s of the EVA based film range suitable for 2D and 3D bag designs we have introduced a range of biotechnology films.

The RENOLIT INFUFLEX barrier films comprise ultra-pure inert PE inner and outer layers and an oxygen barrier. The high barrier properties of these films offer significant advantages in the storage of oxygen sensitive products. The films exhibit extremely low extractables and excellent clarity and are resistant to a wide range of chemicals. The unique film structure combined with a 1,400 mm film width offers excellent weld strength in both 2D and 3D bag designs, which are the new standard in the biotechnology industry.

The raw materials in these films have been carefully selected. Coupled with our film production sites spread across multiple continents, this builds a robust supply chain and ensures longterm availability. In addition, RENOLIT INFUFLEX barrier films are produed under strict controls to minimise the risk of particulates forming.

RENOLIT MEDIPAK UVO offers excellent oxygen, carbon dioxide and UV barrier properties. Available in widths of 125 to 400 mm, this 5-layer co-extruded tubular film is suitable for media bags of up to 20-litre capacity. Special EVA and polyolefin films are available for stem cell storage and cell gene therapy applications. Specially developed materials combine very high oxygen and carbon dioxide transmission rates with excellent cold storage properties down to -196 Celsius (liquid, nitrogen, cryogenic).

Compounds and clean room extruded PVC films and tubing are available for blood collection, processing and transfer sets used in cell and gene therapy applications.

RENOLIT Healthcare is known for its long history in the single-use industry, remains active in conferences and singe-use bioprocessing groups such as BPSA and follows industry guidelines as applicable.
