Medtecs Coverall-美德醫療防護衣

Coveralls are loose-fitting garments that cover the whole body except for the head, hands, and feet. Coveralls are commonly made from high-density polyethylene (HDPE) formed into a non-woven fabric that allows heat and sweat to leave the suit while preventing liquids and aerosols from entering it.

Coverall - Sewing & Tape

Seems are important for leakage prevention

The sewing of coveralls can be the most difficult part to get right. Seams are sealed by putting tape on them for protection strengthen purposes.  However, places, where multiple seams join (such as the armpit), can be difficult to seal properly.  Medtecs, in another hand, has been manufacturing coverall for years, we make sure that hospitals workers can have the best protection in the market.

Coverall Interfaces

Details Matter- Especially Health Workers

Finally, the interfaces on the suit, including the zipper, cuffs, and the edge of the hood or collar, are made liquid-tight to prevent leakage. Cuffs, hood and collar interfaces can be elastic or liquid-tight seals.  In addition, the zipper area can have fabric flaps that cover them or be specially made as liquid-tight zipper assemblies.  For Medtecs’ products, we ensure that interface areas are well protected.

  • Type 1: Protects against liquid and gaseous chemicals. More or less equivalent to US level A.
  • Type 2: Protects against liquid and gaseous chemicals. Non-gas tight. More or less equivalent to US level B.1
  • Type 3: Protects against liquid chemicals for a limited period. Liquid jet tight. 
  • Type 4: Protects against liquid chemicals for a limited period. Liquid saturation tight. More or less equivalent to US level C.
  • Type 5: Protects against airborne dry particulates for a limited period.
  • Type 6: Protects against a light spray of liquid chemicals.  More or less equivalent to US level D
 

Disposable Coverall FAQ

Disposable coveralls are part of personal protective equipment (PPE). They can be used to cover your entire body, as well as other clothing, to protect you from dirt and other contaminants. Coveralls can be one-piece and loosely fitted. They often have sleeves, full leggings, and a hood that covers the head.

The use for disposable coverall 

 

Most disposable coveralls are constructed of non-woven synthetic fabric. As they increase in protection levels, different materials will be laminated together to increase strength, decrease permeability and possibly make it flame retardant.

The coveralls are commonly made with synthetic fibers, such as:

  • Polypropylene (PP)
  • Polyester (PET)
  • Polyethylene (PE)

Besides the fabric materials, there are many different types of lamination and coating of the disposable coverall structure to provide the maximum comfort or protection.

  • Level B – needed at the highest level of respiratory protection and skin protection need at a lesser level. It is included hazardous in waste sites, vapors, or gas.
  • Level C – needed when the concentration and airborne constituents are involved and need air-purifying respirators.
  • Level D – need minimum protection and hazards level of work
