Latest developments at Brückner’s technology center
Long-term experience for various film types
In the world of oriented films Brückner’s technology center with its ultra-flexible pilot line is unique. Film producers, resin manufacturers and converters can rent the facilities and benefit from a broad portfolio of film stretching modes:
Biaxial sequential stretching from the roll or with inline extrusion
Biaxial simultaneous stretching from the roll or with inline extrusion
Both stretching modes in combination with inline coating
Mono-axial stretching in MD or TD direction
Layer configurations from 1 to 7 layers are possible, made by up to 5 extruders
As a result of numerous pilot line tests using a wide variety of resins we can now offer long-term experience for various film types. For detailed information please download the pdf "Pilot Line Experiences".
Our latest developments include:
PE-BSF (Battery Separator Film) in semi-dry process
PP-BSF in dry process
Simultaneously stretched thin PP capacitor film (2.4 – 3.0 µm)
PET-substrate film for printed electronics
Thick PET film for solar back sheet
Multilayer sleeves on the basis of G-PET/ SBC or polyolefins
PP and PET inline coating for perfect metallization and printability
BOPP high shrink cigarette film, low cost, without hydrocarbons
BOPP ultra-high-barrier film with extreme low OTR and WVTR
BOPA / EVOH barrier film with low shrink and low OTR
