The ATHENA SLB operates using ARPAC-HEFESTUS USA patented Shelf Life Booster (SLB). SLB is a unique technology that creates modified atmosphere without drawing a mechanical vacuum at any stage while achieving residual oxygen rates of 1% or less, in some cases as low as .01%. This is unheard of in vacuum free gas flush systems. Additionally, products packed with SLB cause no harm to texture or appearance. SLB extends shelf life without the need for preservatives or freezing.
