Gas flushing and MAP in 1993

As a company that is always at the forefront of the packaging industry, PA developed the use of gas flushing or modified atmosphere packaging for convenience foods long before the concept had even caught on in the UK.

In 1993, PA manufactured MAP machines that were exported to mainland Europe for packing salad and sandwiches. The sandwiches were produced for Marks & Spencer’s Paris store where they were given an 8 day shelf life!

It wasn't until 1997 that the use of MAP started to gain interest in the UK retail market. PA collaborated with one of the pioneers in high oxygen MAP to develop a special vacuum MAP machine that could give sealed packs with 80% oxygen for packing pre-prepared salads with a nine day shelf life.

Just a couple of years later the technology was developed and transferred to the Vision range of automatic high speed machinery giving high volume MAP.

Now MAP is a standard feature of PA’s eclipse tray sealers and is used in a wide range of convenience foods, fresh produce, salads, ready meals, raw meat and fish to extend the shelf life as well as enhance the appearance of the product.
