Bag In Bag Out – BIBO

Cleanroom bag in bag out (BIBO) is a technique used to decontaminate personnel before entering a cleanroom environment. It involves placing contaminated items, such as clothing or equipment, into a bag, which is then placed inside a second, outer bag. The outer bag is sealed, and the contaminated items are removed from the cleanroom through the outer bag.

BIBO is used to prevent contamination of the cleanroom environment by reducing the risk of contaminants being brought into the cleanroom on clothing or equipment. It is often used in industries where the production of sensitive products, such as pharmaceuticals and medical devices, requires a high level of cleanliness to ensure the quality and safety of the final product.

To use BIBO, personnel should remove their clothing and equipment and place it in a bag before entering the cleanroom. Once inside the cleanroom, they should put on clean clothing and equipment. When leaving the cleanroom, personnel should remove their clean clothing and equipment and place it in a second bag. The first bag, with the contaminated items, should be sealed and removed from the cleanroom through the outer bag.

BIBO is an effective way to maintain the cleanliness of a cleanroom environment and prevent contamination of sensitive products.

What is cleanroom bag in bag out (BIBO) used for?

Cleanroom bag in bag out (BIBO) is a technique used to prevent contamination of a cleanroom or controlled environment. It involves using two bags to transfer materials or equipment into or out of the cleanroom. The outer bag serves as a protective barrier to prevent contaminants from entering the cleanroom, while the inner bag is used to transfer materials or equipment.

BIBO is commonly used in industries such as pharmaceutical manufacturing, semiconductor manufacturing, and biotechnology, where it is critical to maintaining a high level of cleanliness and control over the environment to prevent contamination of products or processes. BIBO is an effective way to ensure that only clean materials and equipment are brought into the cleanroom and that any contaminants that may be present on the materials or equipment are contained and do not enter the cleanroom.

How to choose cleanroom bag in bag out ( BIBO ) for your cleanroom projects?

There are a few factors to consider when choosing cleanroom bag in bag out (BIBO) for your cleanroom projects:

  1. Size: Make sure the BIBO bags are large enough to accommodate the materials or equipment you will be transferring.
  2. Material: BIBO bags are typically made of polyethylene or polypropylene, which are both resistant to tearing and puncturing. Choose a material that is suitable for the specific requirements of your cleanroom.
  3. Thickness: The thickness of the BIBO bags can affect their durability and puncture resistance. Choose a thickness that is suitable for your needs.
  4. Sterilization: If you need to sterilize the materials or equipment being transferred, choose BIBO bags that are compatible with the sterilization method you will be using.
  5. Certification: Make sure the BIBO bags you choose are certified for use in cleanrooms or controlled environments. This ensures that they meet the necessary standards for cleanliness and contamination control.
