Ningbo Toprise Security Products Co., Ltd., as a company with 20 years of experience in exporting disposable coveralls, is dedicated to providing quality guaranteed disposable coveralls to customers worldwide. There are many kinds of materials for disposable coveralls, mainly PP, SMS, and SF breathable film material. Here’s where we talk in detail about how to make a choice of these materials.
PP (Polypropylene) non-woven fabric disposable coveralls
Material features: PP non-woven fabric is a single-layer material made by the spunbond method. It is light weight, low cost, with good air permeability and a certain waterproof performance.
The gram weight range of PP non-woven fabrics is generally between 20gsm and 60gsm, and the lower gram weight will provide lightweight and breathable characteristics, while the higher gram weight can enhance the protective performance and durability. Based on sales experience, guests like to choose 38-40gsm.
Advantages:
- Good air permeability, suitable for long-term wear;
- Cheap cost and widely used in low-risk environments;
- Soft and comfortable, it will not cause much discomfort in light protection scenarios.
Disadvantages:
- Limited protective performance. Weak water resistance and chemical resistance.
- Mechanical strength is not high. It is easy to tear and cannot be used in high-risk environments.
Applications: Suitable for low-risk environments, such as daily cleaning, light medical operations, food processing, and other occasions that do not require high-intensity protection.
PP+PE non-woven fabric disposable coveralls
PP (polypropylene) as a substrate; PE is a waterproof material coating.
Material features: PP+PE material is a common composite material widely used in the production of protective clothing. It combines the advantages of PP (polypropylene) and PE (polyethylene) and can provide good protective performance and a certain degree of comfort, especially suitable for liquids and particles with high protection requirements.
Advantages:
Excellent liquid protection performance: PE coating provides excellent anti-liquid ability, especially in medical care, laboratories, chemical, and other environments, to prevent the penetration of blood, body fluids, and chemical solutions.
Good mechanical strength: The PP substrate provides the structural strength of the material, making it have good tear resistance, increasing durability and wearing safety.
Comfortable to wear: Compared with pure PE material, the air permeability and softness of PP improve the comfort of the wearer, especially suitable for long-term wear and free movement.
Economical: The production cost of PP+PE composite material is relatively low, which is suitable for the production of disposable protective clothing, especially in the case of mass production; it has a high cost performance.
Disadvantages:
Poor air permeability: Although PP has air permeability, the presence of PE coating will significantly reduce the air permeability, especially under the thicker coating, which may cause the wearer to feel stuffy and uncomfortable during long-term operation. Therefore, it is not suitable for use in a high-temperature environment for a long time.
Limited flexibility: Although PE coating provides good protection, it lacks flexibility and may limit the wearer’s freedom of movement in some work environments that require a lot of movement.
Not suitable for high-risk chemical protection: Although it has a good protection effect on most liquids and body fluids, the protection performance of PP+PE may be insufficient for some high-risk chemicals, corrosive liquids, or extreme conditions.
The gram weight range of PP+PE composites is usually between 40 gsm and 65 gsm.
Application:
Widely used in hospitals, laboratories, food processing, chemical plants, clean rooms, and other places.
SMS(Spunbond-Meltblown-Spunbond)non-woven fabric disposable coveralls
Mateial featues: SMS is composed of two spunbond layers (outer and inner layers) and one melt-blown layer (middle layer). The melt-blown layer has a fine fiber structure to provide better filtration and protection.
The gram weight range of SMS materials is usually between 25 g and 60 g. A higher gram weight means greater protection, but it also affects comfort and permeability. Based on sales experience, guests like to choose 55-60 grams.
Advantages:
- Good protection performance can prevent particulate matter, bacteria, and limited liquid penetration;
- Moderate air permeability, relatively comfortable;
- With a certain degree of strength and softness, it is comfortable to wear and not easy to tear.
Disadvantages:
- Compared with PP materials, the cost is higher;
- Although it has a certain waterproof performance, the protection effect against strong liquid penetration (such as chemical liquids, blood) is not as good as SF materials.
Applications: Suitable for medium-risk environments, such as general medical operations, laboratory work, the pharmaceutical industry, and other situations requiring a certain amount of particle and liquid protection.
SF (Spunbond + Film) non-woven fabric disposable coveralls
Material features:
SF material is a composite material of spunbonded non-woven fabric and a layer of microporous breathable film. The breathable film can block the penetration of liquid, blood, and chemical substances and has certain breathability.
SF materials usually consist of a thick spunbond layer with a breathable film, with a common gram weight range of 40gsm to 65gsm, and are designed for high-risk environments. Based on sales experience, guests like to choose 55-60 grams.
Advantages:
- High protection performance, especially in the penetration of liquids and chemical substances, has a significant advantage.
- Strong water resistance can effectively prevent the penetration of liquid, blood, and body fluids, suitable for a more stringent working environment;
- At the same time, it is breathable, and the wearer will not feel too stuffy.
Disadvantages:
- Higher price, more expensive than PP and SMS materials;
- It may not be as soft as SMS, but it is usually comfortable enough to wear for long periods of time.
Applications:
It is suitable for high-risk environments, such as emergency protection, operating rooms, infectious disease isolation, chemical protection, and other occasions requiring high-level liquid and particulate protection.
Material selection suggestions
- PP (polypropylene): lightweight and breathable, suitable for basic protection in low-risk environments, such as daily cleaning or light protection scenarios, at low cost.
- PE+PP: PP non-woven fabrics combined with PE coatings provide good liquid protection and moderate permeability, suitable for medium-risk environments, such as medical, laboratory, and other occasions requiring liquid barriers.
- SMS: Spunbond and melt-blown composite material with strong particulate protection and permeability, suitable for medium-risk medical operations or industrial applications, protection, and comfort balance.
- SF Breathable membrane: spunbonded non-woven fabric combined with microporous membrane, with high liquid and chemical protection properties, suitable for high-risk environments, such as infectious disease protection, chemical treatment, etc.
Conclusion
In summary, the choice of materials should be weighed against the risk level, cost, and comfort of the actual application. In the production process, it is also necessary to consider the design and applicable standards of protective clothing to ensure that its protective effect meets the relevant industry requirements.
