BOPE-films for white cavitated food packaging
TF-BOPE white cavitated films are aimed at printing and laminating applications, when a superior film surface appearance in combination with an outstanding printing quality are mandatory.
Applications
Typically, such films could be used in pouching, confectionary packaging and other demanding, co-extruded or laminated packaging applications.
Save costs and resources!
Additionally, the cavitation process („voiding“) offers the opportunity to substantially reduce material consumption in BOPE-film extrusion by reducing the specific weight of the film per square unit.
This massive increase in yield and efficiency means, that with the same amount of polymer much more square metres of BOPE-film can be produced.
Packaging of the future – Discover the new technology!
BOPE films are a milestone on the way to so-called mono-material solutions; these are flexible packagings, which consist of only one polymer. That makes recycling much easier and in some regions of the world it even creates the technical prerequisites to do the recycling at all.
CONSTAB – We offer innovative BOPE-masterbatches for your needs!
All these benefits can potentially be achieved with the combined usage of two newly developed, tailor-made BOPE-masterbatches:
- CONSTAB CON-X® FL 826 PE for cavitation
- CONSTAB CON-X® CC 160 PE for whiteness
Both masterbatches are commercial products, which are globally available!
Trust in strong partners and common development!
Together with CONSTAB‘s development partner Brückner Maschinenbau GmbH & Co. KG, Germany, a team of dedicated engineers and chemists successfully demonstrated this most innovative BOPE-film extrusion technology – with amazing results!
Pilot line trials were conducted to optimize sequential BOPE-film extrusion processing (TF – tenter frame) as well as polymer and masterbatch selections, to achieve this technological break-through. Within a range of 20 µm to 50 µm of total film thickness, film densities between 0.5 g/cm³ and 0.7 g/cm³ were obtained with an extraordinary retention of mechanical properties (stiffness).

CONSTAB is convinced, that this new technology further helps to promote a globally circular economy, to preserve precious food and resources, and to protect health and environment.
Another motivation on this path is the recently received award “Climate Neutral Company“.
CON-X® Masterbatches are available for additional applications.
