Materials


Overview

The material or materials chosen for your medical device needs to flex with the amount of movement in the part of the body it is intended to be applied to, while providing the correct amount of support to the adhesive used, in order to prevent unwanted peeling.

Some of the materials we use to manufacture medical devices are below.

 

Stiff Polyester

This type of backing provides excellent resistance to adhesive peeling, however it is quite inflexible and as such is not recommended for many stick to skin applications.

Paper

Paper backings are used in a number of medical devices, from simple dressings to paper tape.  Using a paper backing means a tape or dressing can be torn, rather than cut with scissors, making it quicker and easier to apply.

Paper backings vary in terms of their resistance to adhesive peeling and body movement.

Woven Materials

Woven materials are strong, breathable and flexible and as such are widely used in medical device manufacture, for products including surgical gowns and masks, drug delivery, wound dressings, and plasters.  Woven materials are also used for medical packaging, as their porosity allows gas sterilisation.

Woven materials can fray along their edges, meaning they can be deemed unsuitable or inconvenient for longer wear applications or use on areas of the body that experience a high degrees of movement.

Non-woven Materials

Non-woven materials can be manufactured to a chosen set of criteria, including porosity, fabric weight, thickness and sterilization capacity.  This flexibility and their high resistance to tearing and fraying, natural absorbency and hypoallergenic nature makes these materials a cost effective choice for single-use, disposal products that don’t require re-cleaning or sterilization such as absorbent pads, drug-delivery devices and bandages.

Non-woven materials can be manufactured using eco-friendly, natural fibres, which are biodegradable, recyclable and renewable.

Foam

A number of foams are used extensively in medical manufacturing for a number of solutions, including wound care products and consumer healthcare, as this material is typically light-weight and durable.  Furthermore, it can be impregnated with a number of solutions, such as fungicidal and bacterial additives to create a product with accelerated healing properties.

Foam also has vibration dampening and insulating properties that make it highly suited to medical packaging solutions.

 

 

Film

Films can be manufactured to exacting specifications concerning antimicrobial properties, breath-ability, bio-compatibility and heat stability.

Due to this flexibility films have a number of purposes within the medical industry, they can be used in the manufacture of wound care products and their release films, surgical gowns, medical fluid bags, trans-dermal patches and medical packaging.

Films can also be laminated onto synthetic non-wovens, wovens or any textiles and used in single-layer or multi-layer constructions.
