It is essential to keep Surface-Mount Devices (SMDs) dry from manufacturing point to the time of reow soldering. Moisture Barrier Bag,

also known as Vapor Barrier Bag, is made by multiple layers of plastic and aluminum that control moisture vapor leakage.

Basically, there are 3 kinds of Moisture Barrier Bags (MBBs), Tyvek MBB, AMBB and ANMBB, in the the market. The key factor of moisture

barrier function of the bag is a metal layer, like thickness of the foil layer, foil or metalized, etc., but thickness or material of other layers

will partially aect the quality of MBB as well.


Tyvek MBB is ideal for moisture sensitive devices or components, and especially is suitable for sharp-shape components

thanks to its excellent puncture resistance.

Thickness: 307μm, 247μm

MVTR*: < 0.02 g/100 sqinch/24h

AMBB is a good choice for moisture sensitive devices and components. Depending on the products stored in the bag and the periods of

storage, you have several selections on AMBB by adjusting the total thickness of the bag, the thickness of AL foil layer, etc.


Thickness: 62~200μm (Common: 100μm, 150μm)

Maximum width: 1,250mm

MVTR*: < 0.02 g/100 sqinch/24h

ANMBB is a new technology for barrier materials, which reduces material cost. Aluminum is vapor-deposited onto polyester lm or

nylon lm. This cost eective bag comparing to AMBB is suitable for medium to short term dry-packaging users.


Thickness: 62~200μm(Common: 90μm, 100μm)

Maximum width: 1,250mm

TMBB has no metal layer, but it can be used for less moisture sensitive devices and this bag can be a good choice for foods packing

too, which requires clean and vacuum properties.
