Vacuum bags suitable for vacuum machines with external suction. The bag has a side “honeycomb” embossing derived from a film lamination process providing a homogeneous thickness and a barrier to the upper oxygen, assuring a longer conservation of the product and reducing punctures. Available in standard sizes, no logo boxes, in blister of 100 pcs with bar code on each single package. The SF structure is also available and it is suitable for heat-treatments such as pasteurization and sterilization.
