BLOOD & BLOOD COMPONENTS

The  packaging of blood and blood components is known to be one of the most critical applications of polymer medical films. The developments are frequent and the requirements are increasing every day.

RENOLIT Healthcare is the worldwide market leader for the basic materials for the manufacturing of blood bag systems. The RENOLIT  TRANSFUFOL, RENOLIT INFUFOL and RENOLIT ES blood bag films are supplied to the world’s leading manufacturers of blood bags and blood processing systems such as aphaeresis and therapeutic treatments. An important factor is the consistent and reliable quality of the films, often custom made in co development with our customers.

The features include superior embossing stability during  steam sterilization procedure, guaranteeing the non-blocking properties on both sides of the film. Different surface structures are available enabling a good blood separation both on automatic as well as semi-automatic fractionation machines. 

The compositions of RENOLIT blood bag films have been carefully tested for their blood compatibility.

Various formulations are available, including DEHP, TEHTM, DINCH, DEHT and citrate plasticised films. Special PVC and polyolefin compounds offer high oxygen and carbon dioxide permeability for platelet storage as well as for frozen and cryogenic storage. Thickness ranges from 0.20 to 0.75 mm and the widths from 50 to 1350 mm, depending on the film type.

The specially developed RENOLIT TRANSFUFOL film processing technique combines the advantages of calendering and extrusion, resulting in a superior batch-to-batch consistency. The strict clean room conditions, web cleaning technology and in-line slitting guarantee low particulate levels. Our advanced composition and production technology for RENOLIT MEDITUUB MAT and LIMA results in blood bag tubing with anti-kinking and anti-sticking properties after sterilisation.

RENOLIT TRANSFUFOL, RENOLIT INFUFOL, RENOLIT ES films, RENOLIT MEDITUUB and RENOLIT MEDIGRANUUL are used for the manufacturing of critical blood contact devices such as:

• blood bag systems
• flexible leucocyte filters
• aphaeresis systems
• transfusion systems
• pathogen inactivation systems
• platelet pool bags
• venous reservoir bags
• and many more.

ALBUMIN IN FLEXIBLE PACKAGING
Plasma derivates such as albumin are traditionally packed in glass containers. RENOLIT Healthcare offers a range of materials for the manufacturing of flexible bags for the packaging of plasma derivates, including primary barrier films, allowing a long shelf life of the packed product.
