ASO Clean Laminated Bag

ASO Clean Laminated Bags" are produced in our class 10000 cleanroom using our new processing method, which achieves a very high level of cleanliness. Hence, we avoid inadequate cleanliness of the film surfaces (the greatest disadvantage of laminated bags produced by the conventional processing method).

Overview

"ASO Clean Laminated Bags" are produced in our class 10000 cleanroom using our new processing method, which achieves a very high level of cleanliness. Hence, we avoid inadequate cleanliness of the film surfaces (the greatest disadvantage of laminated bags produced by the conventional processing method).

The additive-free polyethylene film used in ASO Clean Film is used as the innermost layer that comes in contact with contents. Hence, the risk of additives bleeding out and insoluble particles being produced is minimal. No adhesive is used to bond the films, which makes the Clean Laminated Bag appropriate for use in the pharmaceutical and electronic device applications.

Features

  1. The "ultraclean laminated bags" are produced in our class 10000 cleanroom. Dedusting of both surfaces of the plastic films, which is generally impossible for reclosable bags, is achieved using a state-of-the-art processing method.
  2. The "completely additive-free material" used for many years in "ASO Clean Bags" is used for the innermost layer that comes in contact with the contents. Hence, this product can be used without having to worry about problems caused by additives. Clean Laminated Bags can be used directly, instead of needing place a clean plastic bag inside a standard laminated bag.
  3. "ASO Clean Laminated Bags" are sealed in packs of a unit number of bags and can be kept clean until required.
  4. Upon your request, we can also provide gamma-ray sterilized bags.

Comparison of particles adhering to the inner surface of the bag

The following tables compare the numbers of particles adhering to the inner surface of our Clean Laminated Bag and a commonly used standard laminated bag. Relatively new plastic bags produced about one week before testing were used.

[Measurement method]
The bags were filled with 100 mL of dust-free water with a blank count close to zero and then the bag was tied at the top. Then, 10 mL of the water was taken out of the bag and the number of particles in this sample was counted. This measurement was repeated three times and the average value calculated. The total particle numbers are shown in the tables above.
* Measuring device: Particle counter from RION
