Pioneers in Metal Detectable Plastics - Ensuring Food Safety with High-Quality Detectable Products
Who are BST and what do we do?
B S Teasdale & Son Ltd are the original pioneers of metal detectable plastics for the food industry. We were first established in 1985 by Brian S Teasdale, a former senior engineer at British Bakeries. Brian was the first engineer to address the issue of plastic contamination in food in this way, and it is with great pride that his initials are still represented by the ‘BST’ brand that’s well known and respected in the food industry.
BST are best known for the BST DetectaPen Range. These metal detectable, x-ray visible, and antibacterial pens can be found in most food processing environments, preventing foreign body contamination across a variety of industries.
Today the company is led by John S Teasdale, who has continuously driven the growth of the company since taking over from his father in 2002. We supply a wide range of food grade detectable products to all corners of the globe for use in food and pharmaceutical production areas. As of June 2024 we employ 24 people, produce around 1.8 million detectable pens per year, and stock approximately 400 different detectable products.
BST’s core strengths are our commitment to high quality products and materials, as well as our bespoke manufacturing capabilities. Our primary material, BST XDETECT® has benefited from years of refinement making it one of the most durable, colourful, and shatter resistant food safe detectable plastics available on the market.
How do detectable products work and why use them?
Detectable products can take two main forms, the first being a product entirely made from a specially developed detectable material. In the case of BST XDETECT®, this is a polypropylene-copolymer infused with ferrous and high-density additives. The ferrous additive is designed to disrupt the magnetic field of a metal detector, whilst the high-density additive is designed to show clearly on an x-ray image. The plastic is compounded to a precise formulation, with exactly the right ratios of each additive resulting in a plastic that’s metal detectable and x-ray visible whilst retaining the mechanical performance of the polypropylene-copolymer. This mechanical performance is an essential but often overlooked element, as if the finished detectable product doesn’t break in the first place, it’s far less likely to end up contaminating the food in production.
This precisely compounded plastic is moulded by BST into a wide range of detectable products, including pens, scrapers, clipboards, boxes, jugs, and numerous bespoke parts as required by our food processing customer base. Food processors have peace of mind that their plastic food processing items are safe, display due diligence in preventing contamination and are in compliance with HACCP and BRC procedures.
The second form of detectable product is a standard food processing item that has been modified to give it detectable properties. Examples include hairnets with metal grips, mob caps with foil strips, and paper traceability tags with a metal foil core.
Why choose BST?
Most importantly, we care. As the original developers of detectable products and materials, we do not like to see low quality or dangerous products on the market. As such we undertake in-depth research and testing with every new product development to ensure that it is fit for purpose.
We work closely with leading metal detector and x-ray system manufacturers to test our products performance, document the results, advise our customers, and find ways to improve our materials. As a small and family-owned company, we pride ourselves on integrity, sustainability, and excellence in everything we endeavour to achieve.
