The Seevent Plastics story began in the early 60’s, when the original company manufactured a bomb carrying device, which fitted under the wing of the Phantom Jet, for the MOD. However, when the need for these carriers diminished, they needed to diversify, and with one 56in Harden bag machine and a MAF 4 colour printer, started to manufacture medical bags and printed potato sacks. A few years later in 1972, they acquired a plastics company with the patent rights to produce ventilated polythene, small pinprick holes which allowed the goods packed inside to breath, initially used for wrapping soft cheeses, sausages, ham hocks and seed potatoes.

In 1987 the name was officially changed to Seevent Plastics Ltd and production started on printed polyethylene coal sacks, making our mark as one of the leading manufacturers of high strength industrial polyethylene sacks in the UK. However, we believe in continued investment and following our strong history of innovation acquired Polyplus Packaging in 2016 and together from our sites in Lancing, West Sussex and Reading, Berkshire, we are able to produce in excess of 130 million bags a year across 19 machines in a diverse range of packaging solutions including End Weld Bags, Single Wound Sheeting, Centrefold Sheeting and Tubing.

Our unique blends have continued to be developed over years of experience and knowledge, offering our customers flexible, bespoke packaging, in a wide variety of options, including specialised Anti-Static, Anti-Corrosive and Grip Seal bags, ideal for industries such as Medical, Engineering and Electronics, and our Xtrastrong range which has been purposefully developed for heavy duty packaging such as Aggregates, Rubble, Coal and Animal Feed.

However, at Seevent Plastics we don’t rest on our laurels and have often been at the forefront of reducing packaging waste through innovative solutions. In 1995 we developed our Xtrastrong blend, which led the way in down gauging packaging throughout the industry, and in 2020 we introduced Post Consumer Waste into our packaging, once again reducing the virgin polymer demand. We understand that only by looking for new ways to add value, improve performance and reduce costs can we provide our customers with a solution that meets their changing needs.
