We are one of the pioneers in the development of ESD oriented plastics and laminates. We continue to maintain the ranking as a leading supplier of superior engineered moisture barrier bags and clean room packaging.
Drypack DB 3000 series moisture barrier bag
Drypack DB 3000 series is specifically designed to provide superior moisture vapor barrier yet fully transparent. This proprietary film lamination structure enables you to see through to the contents and perform barcode scanning.
- Low MVTR @ <0.05g/100in2/day
- Enhanced contents protection from moisture
- Easy content identification and bar code scanning
- Minimal charge retention
- Safeguards static sensitive devices
Drypack DB 3000 series uses film that is designed for packaging of Hard Disk Drive applications. These packaging materials have the same antistatic inside sealant layer, a very thin layer of vacuum deposited aluminum on a substrate or solid and with the moisture barrier layer to provide moisture protection.
Drypack DB 38XX series moisture barrier bag
Drypack DB 38XX series is a high barrier foil laminated film developed for semiconductor industry. It is a popular choice to vacuum pack tape and reel, IC trays or shipping tubes.
- Superior MTVR, < 0.0003 g/100 in2/day
- Excellent vacuum retention
- A solid Aluminum foil middle layer
- Total EMI/ESD protection
- More than 25 lbs puncture resistant
- Prevent bag puncture against sharp corners of IC tray or shipping tube
The film has an antistatic inside sealant layer, an embedded solid foil layer to insure against moisture vapor transmission and an outer layer selected to maximize packaging strength or vacuum retention. The embedded solid aluminum foil layer acts as a barrier against ESD, moisture vapor transmission and also provides EMI shielding from all RF signals and EM radiation.
Drypack DB 33XX
A solution developed for Surface Mount devices (SMD).
Drypack DB 33XX series employs a static dissipative outer layer of polyolefin and a cost effective alternative to DB 38XX series. A solid aluminum foil middle layer and an inner layer of antistatic polyethylene are used to provide moisture vapor protection and guard contents against triboelectric charging.
Nylon PE series
Nylon PE is ideal for packing sharp objects such as fastener where puncture resistance and durability are required. The film is transparent clear, strong and vacuum heat sealable.
- Reinforced with nylon
- High puncture resistant
- Transparent clear
- Contents remain visible while protected
- Readily heat sealable
Static Shielding Bag
These packaging materials are made up of layers (a lamination), one of which is metal. The metal layer in static shielding bags is either a very thin layer of vacuum deposited aluminum on a substrate or a solid. The metal is sandwiched between the plastic layer, typically polyester (PET) and antistatic polyethylene(PE), on the other side act as a sealant layer which prevents the bag contacts from becoming electro statically charged during movement. The “buried” metal acts as a shield. Should an ESD strike the outer surface of the bag, the metal will shunt the discharge energy, spread it out over the surface of the metal and reduce its dangerous energy to a small fraction of the original charge.
