Vacuum packaging extends shelf-life, ensures quality, prevents products from drying out, protects it from outside influences and improves hygienic handling.
Vacuum packing is a very cost effective procedure for preserving perishable food products. Very low packing material costs, short process times and a relatively low investment for long-lasting equipment makes vacuum packing by far the most economical and most efficient way of packaging perishable food products. But also for other applications, such as protecting goods and space saving logistics or storage, vacuum packing is an ideal solution.
Vacuum bags and film
For vacuum packaging special vacuum bags are required. The bags are coextruded with mostly a combination of polyethelene (PE) for strength, but also for sealability, and nylon (PA) as a barrier to prevent air from penetrating the bag over time. Good quality bags will maintain vacuum in the bag over a long period. The bags are often treaded so that they don’t stick together and processed in a clean environment. Special cook bags will allow the product to be heated in a water bath.
