Description
BERNHARDT’s 4SL bags with side gussets are designed with four lengthwise seals. So, it gives them high rigidity and excellent stability. Moreover, we particularly recommend them for large volumes. They also come in laminated or co-extruded films, with EVOH or aluminium barrier film.
The films with 4 or more layers include a polyamide layer. This gives the bags extra strength for vacuum packing.
BERNHARDT can guide you in the choice of material and type of barrier film most suited to your packaging needs.
