Quality Control

Nearly all products are manufactured in-house and are continuously monitored within our QC laboratory to ensure conformance to specification, including sterilisation indicators and construction performance levels. All products are manufactured under ISO 9001 and ISO 13485 quality systems and comply with ISO 11607 parts 1 & 2 and EN868 parts 2-10 as appropriate. As medical packaging standards continue to evolve, Westfield Medical will ensure continued compliance.

Pack Design

To meet the challenge of increasing legislation and new medical applications and procedures, Westfield Medical continues to respond with product and process improvements. To ensure you get exactly what you need, we offer a bespoke design service using our CAD systems for concepts and pack creation, providing mock-ups and sample materials as appropriate. Trials can also be arranged on our production machinery. We offer help and advice across all aspects of packaging design, from material specification and process indicator technology to legislative compliance.


From receipt of order through to despatch of goods, all product specifications and process routes are prepared and controlled using our unique computer software systems. This minimises delays and provides increased flexibility, ensuring a fast response to customer requirements. In-house manufacturing includes multi-colour flexographic printing, producing customer-specified designs on a variety of materials. These include plain, crepe, registered adhesive and all-over coated papers, coated and uncoated Tyvek® and a variety of co-extruded and laminated materials.


Final conversion of plain and printed materials is undertaken on a range of special-purpose machines, some designed and developed by us. These produce various packaging formats including bags, pouches, rolls and sheets, in a variety of sizes and styles.

Located between Bath and Bristol in Southwest England, our dedicated manufacturing unit benefits from good access to motorways and airports for prompt distribution worldwide. We maintain within our warehousing facilities both finished products and buffer stocks of raw materials, as back up to our JIT manufacturing systems, providing safe margins against unpredictable demand.
