    • B+K LidFlex® Lidding Films

      B+K offers laminates specifically for your product and its requirements. The lidding films have outstanding sealing properties and enable simple punching or cutting out.

    • B+K U-Pack® Side gusseted bag

      The side gusseted bag B+K U-Pack® was specifically developed for dry goods and is characterised in particular by its form stability.

    • B+K AluFlex®

      In particular, B+K offers sealed versions in the form of B+K AluFlex® seal as an individual sack solution.

    • B+K AluFlex® FFS

      The B+K AluFlex® product range is very suitable for moisture-sensitive, oxygen-sensitive or odor-intensive products. By use of a laminate of aluminium or metallized polyester, the oxygen and steam barrier are optimally adapted to the individual requirements of the respective product.

    • B+K BackFlex® PP Backsheets

      The future of solar energy requires backsheets which allow for safety and future uprating. B+K BackFlex® PP unites both in a co-extruded film - made in Germany.

    • B+K CleanFlex® Bag Systems

      Active pharmaceutical substances, in particular, are still filled into and stored in expensive aluminium cans, involving considerable logistical effort. Specifically, cleaning the cans after use, transportation and storage of the empty cans cause significant costs. Therefore B+K developed clean room produced PE bags and aluminium compound bags as liners to avoid contamination of the external containers.

    • B+K CleanFlex® Barrier Bags

      The simple appearance is misleading, as the laminated aluminium bags with three sealing seams are high-barrier packaging products.

    • B+K CleanFlex® Bottle-shaped bags

      We have been producing B+K CleanFlex® bottle-shaped bags for a number of years, with constantly growing experience and increasing improvements. For example, special sealing radii and cut-and-finish seams have led to important development steps.

    • B+K CleanFlex® Containment Systems

      High-Containement systems become more and more important. The encapsulation of complete processes offers improved protection for operators and product safety, at the same time it taps the full potential of cost-saving in the classic clean room environment.

    • B+K CleanFlex® Continuous Liner Systems (CLS)

      Continuous Liner Systems (CLS) or endless liner are a simple and effective solution for operator safety and product protection. 

      This tubular film is gathered over several meters in an axial direction to facilitate the application process at the customer's site.

    • B+K CleanFlex® Gloves

      Processes in semi conductor and in medical industries require extrem clean handlings.

    • B+K CleanFlex® HeaderBags

      Thanks to the strip made with DuPont™ Tyvek® with its microbiological barrier, the bulk product can be ETO-sterilised within the bag.

    • B+K CleanFlex® Tyvek®/HDPE Bags

      The combination of a PE bag with DuPont™ Tyvek® material enables the product to be sterilised using water vapour through the surface of the packaging material. As a rule, the front is manufactured from DuPont™ Tyvek® and the rear from HDPE; however, full DuPont™ Tyvek® packaging material is also possible, as is the integration of a window made with DuPont™ Tyvek®. Our so called "SteriBags" are therefore perfectly made for steam sterilization.
