Find out how PE film packaging can offer an attractive alternative to paper sacks

Paper sacks, with or without a film layer as protection against moisture, only protect your powdered products against moisture for a limited time. Conversely, the B+K PowFlex® product range offers a ventilation option and provides long-term protection against moisture. This advantage ensures a much longer shelf life compared to paper bags even when stored outside without any plastic covering.

The product line includes form, fill and seal films and valve sacks, whereby both options offer easy opening features for end users’ convenience. At present, B+K PowFlex® bags can contain up to 50% PCR (post-consumer recyclate) and are a sustainable alternative to paper bags. This webinar offers a deep-dive into the different solutions B+K has on offer, including:


The ideal form, fill and seal packaging (FFS) is a highly ventable and dust-free FFS film with which even finely powdered products can be packaged securely and easily.


Do you want convenience? Each sack section is provided with a tear-open perforation for opening the sack and forming a discharge opening. Optionally, an adhesive strip can be attached to the sack to close it again after only partial emptying.


B+K PowFlex® is made of 100 percent PE and can be manufactured with up to 50 percent PCR (post-consumer recyclate). This packaging solution for industrial products is therefore an important contribution to a better circular economy.


The further developed B+K PowFlex® vs (valve sack) is a real alternative to paper valve sacks with a film layer in the building materials, chemicals and food industry sectors.
