Fulfilling the need for a clear, durable, low permeability packaging film for the electronics industry, BB-450 is engineered to offer superior protection and the highest degree of vacuum retention. This structure is ideally suited for packaging disc media, wafers, sputtering targets, lead frames, cathodes and other moisture sensitive components which require state-of-the-art safeguarding. The proprietary lamination has been constructed to incorporate clarity for reading lot codes or information through the package and a high moisture and gas barrier for extended shelf life in a wide range of storage temperatures. Readily heat sealable, it exhibits superior impact strength and resists abrasion and particulate sloughing. If particulate contamination is a concern, BB-450 can be provided cleanroom certified for stringent contamination requirements. This structure is available in side-sealed tubing, sheet and a variety of bag sizes.
