B+K PowFlex® ffs powder packaging is a highly-ventilatable and sift-proof FFS film which can also be used to package finely powdered products reliably and simply. This plastic packaging offers significant advantages in comparison with paper packaging, particularly for mixtures containing cement.

Thanks to high moisture protection, the product is securely packaged under all weather conditions – even without protective packaging. This significantly increases the product's life. The film enables safe and clean transportation due to its high dart impact resistance. B+K PowFlex® ffs is also optimal for other hygroscopically sensitive products such as chemicals or foodstuffs in powder form.

One variant is the newly developed B+K PowFlex® premium eo. It is equipped with an easy opening function and a resealable closure. Both are of great benefit to the end consumer, because they make handling simpler and protect the product even after initial opening.

Cost Advantages
B+K PowFlex® ffs offers cost advantages in comparison with the paper valve sacks which are used as standard. The unfilled packaging offers savings of up to 40 percent in terms of transportation costs and as much as 80 percent as regards warehousing costs, because a pallet is able to carry up to five times the quantity of B+K PowFlex® ffs packaging units in comparison with a normal packing scheme for empty paper sacks! The sack filling capacity of the machine technology which is used can also be significantly increased, and PowFlex can stand up to any comparison in terms of individual sack costs.

Design advantages
High printing quality, diverse film colours, glossy or matt films, various surface structures, different laminate structures – B+K PowFlex® ffs offers entirely new presentation and marketing options. B+K is also happy to be of assistance in individually adapting the ventilation options, and has access to a multitude of tried-and-tested manufacturing variations. Formats and materials are defined according to your individual requirements. Make use of our know-how!

B+K PowFlex® vs powder packaging

The B+K PowFlex® vs (valve sack) is a genuine alternative to paper valve sacks with an intermediate layer of film in the construction material industry and a sensible addition to the B+K PowFlex® FFS product range. Naturally, the sacks can also be used for other powdered products, e.g. in the chemicals or foodstuffs industries.

100 % PE, single-origin and completely recyclable

Thanks to our new ventilation system, the single-origin PE valve sack is able to ventilate just like a paper sack during and after filling. After the filling process, the ventilation system closes automatically. Since our B+K PowFlex® vs sack can be filled on existing lines, investing in new FFS filling lines is not necessary.

Overview of product protection
Paper valve sacks, with or without an intermediate layer of film as moisture protection, only protect your powdered products against moisture to a limited extent. Conversely, our B+K PowFlex® vs plastic valve sack offers ventilation and permanent protection against wet and moisture.
 

· Storage tests (storage outdoors) confirm its longer shelf life.
· This film sack offers the foodstuffs industry extensive hygiene advantages.
· After the filling process, our sacks can be optimally and cleanly palletised using robots or by hand, and retain their shape. With appropriate printing, the palletised sacks are also ideal for advertising purposes.

The two-ply separable packaging is the hygienic solution for high sensitive products, such as foodstuffs, food supplements, pharmaceutical precursors and special chemical products. B+K SepaFlex® is available as FFS-film or premade open mouth flat and side-gusseted bags.

Advantages
The outer film protects the inner layer and the product against contamination of dirt, dust, mold and humidity during transport, storage and handling. The outer film can be removed easily and without residues thanks to peelable welding seams - without using a knife. This guarantees absolute cleanliness of inner packaging and prevents contamination from end-use environment. SepaFlex® is produced of pure polyethylene - this means an extended product shelf life and a sorted packaging disposal.

Conformity
Conformity with food contact legislation for packaging is assured. Used raw materials comply with FDA requirements and GB standard.

B+K SmartFlex® stretch hood film is the secure, economical, effective and intelligent stretch hood film for a wide range of packaging.

Maximum possible safety
In contrast to shrink films, no heat or naked flames are used when applying stretch hood films - the risk of fire is therefore eliminated. There is no risk of the pallet protection film's becoming laminated with the palleted film bags beneath. The stretch hood offers optimal protection against dust, dirt and moisture, and is also ideally suitable for outdoor storage. It can additionally be equipped with UV stabilisation if necessary. If the packaged product also has to be protected from UV radiation, the films can be equipped with a UV barrier. B+K SmartFlex® stretch hood films offer outstanding protection against manipulation and theft of the goods, as opening the protective packaging can be noticed immediately.

Stable securing of loads
High retention forces and high dart impact and tear resistance enable stable load securing along the entire logistical chain, from loading and transportation to the end customer. The optimal film thickness and recipe for achieving this are defined depending on the weight and properties of the packaged product and the customer-specific requirements.

Perfect presentation
Transparent and crease-free application of the pallet stretch hood enables optimal visual presentation of the packaged product. Further marketing options are available through colouring or printing in multiple colours.

High variant diversity
B+K offers a wide range of equipment options such as e.g. reduced thickness films, perforation, hole punching, UV stabilisation, UV barrier, printing or colouring.

Sacks may be made of synthetic materials or laminates, for various weights. They may be filled through the valve, which then automatically seals itself, thus preventing any leakage.
The filled valve sack forms a block, by way of the standing base and valve, which is then very stable and stackable. The possibility to print the package on all sides provides ample space for product information.. Valve sacks with special ventilation options, by way of ultra fine perforations or labyrinth vents, are especially suitable for powdery contents.

Equipment
Various applications offer our customers diverse options:
•    Different valve forms (stepped fringe valve, exterior sleeve, internal sleeve valve, etc.)
•    Pouring holes and aids
•    Resealing options
