Terms and phrases that we frequently use.

Oriented film
Oriented film
Practically everybody uses them to protect sensitive goods – high-quality oriented films are undoubtedly the number one within the world of packaging material. More and more they are replacing paper, cardboard, tin foil and other materials.

Upon applying a particular process, mono- or biaxial orientation, the films obtain a wealth of advantageous properties, due to a change in the morphology of the film’s molecular structure:


  • excellent mechanical properties, e.g. stiffness, tear, shock or puncture resistance
  • impermeability to moisture and steam
  • high resistance to oils, fats and solvents, as well as to heat and cold
  • dimensional stability and scratch resistance
  • attractive glossy appearance, thanks to brilliant surface quality and high transparency
  • excellent convertibility, printability and sealability.


Film Production Methods

Oriented film for technical applications

Brückner has developed adequate line layouts based on its unique in-house technology center allowing sequential and simultaneous stretching:

  • optical films, made of COC, COP, PC, TAC or PET: Clean room suitable sequential and simultaneous technologies for the production of these films – mostly used for the fast growing flat panel display market: polarizer film, retardation film and protection film
  • high temperature films: Sequential concepts, based on profound research and development for the processing of PTFE, PEEK or PEI used within the textile industry, for membranes in the medical sector and for flexible printed circuits and insulations

Packaging has become a key marketing tool at the point of sales. As a result, customers in supermarkets and stores are placing greater emphasis on attractive packaging.

This leads to a greater demand for a variety of speciality films:


  • co-extruded multi-layer structures, up to 7 layers for ultra-high barrier
  • shrink film and sleeves for trendy, full body shape labels
  • ultra-high barrier film for lamination
  • BOPA film highly suitable for freezable and cookable (microwavable) packaging
  • mono-axial shrink films for bundles and labels
  • bio-degradable films for environmental protection and sustainability
