BioShell Custom Designs for Single-Use Bulk Bags
With its BioShell protection system, UFP Technologies (
BioShell is constructed of light-weight, dual-density foam in either a hinged clamshell or a two-piece top-and-bottom design. Higher density foam on the outside provides structural integrity and puncture resistance while softer foam on the inside offers cushioning during impacts.
The system is designed to protect bags at temperatures as low as –70°C. With a glass transition temperature of –85°C, BioShell retains flexibility and cushioning properties in most low-temperature applications, says Tuna Sava, manager, BioPharm Products, UFP Technologies.
BioShell is made from high-purity USP Class VI foam that is converted from rigid plastic using only nitrogen without any traditional toxic foaming agents. It contains no CFCs or HCFCs.Shipped clean-room-ready, the system is lightweight, and stackable, and nestable, which provides ease of handling, reduces shipping costs, and minimizes storage space. The units are designed for multiple use.
The BioShell units are customized to each application, whereas competitors have offered standard designs for common bag sizes,
Material density and wall thicknesses are varied to increase or lower the thermal conductivity of the units to adhere to freeze/thaw times required for a bag and its contents.
“Frozen ingredients stored in plastic bags need to be protected inside the plant and in shipping. Systems made of rigid plastic provide little impact absorption against a drop or accidental bumps,”
The single-piece system follows bag contours and braces it without additional components or dunnage--reducing part numbers.
Manufacturers are moving to plastic disposable technology for handling contents, replacing stainless-steel tanks with single-use bags. Besides being bulky and hard to store, tanks have to be cleaned and validated at each stage of filling, storage, shipping, and receiving,
Customers of the BioShell include Genentech, Merck, Shire Pharmaceuticals, and Laureate Pharma,
