Weir & Carmichael are specialists in the supply of woven polypropylene sacks. We are recognised as one of the UK’s leading supplier of woven polypropylene sacks with annual sales in excess of 12 million sacks. A tough, tear resistant material, woven polypropylene is ideally suited to a range of packaging applications such as engineered parts, pulses, animal feed, seed, confidential waste paper and chemical powders.
We offer customers the option of polypropylene sacks printed to their own individual design requirements. We have four flexographic printing machines capable of printing up to 3 colours on each bag face. We have replaced solvent-based printing inks with water-based inks as part of our commitment to more environmentally friendly production methods. With short lead times, including time critical deliveries, we produce printed sacks of the highest quality thanks to the expertise and experience of our printing team. For more stringent print requirements, look at our Gravure Printed Bags page.
