Transparent skin and blister packages enclosing steel panels and various small items were fabricated by vacuum forming and electronic sealing equipment and submitted to various laboratory accelerated tests for evaluation. The results of these tests indicated that a polyesterpolyethylene laminate as a skin packaging material would provide level A protection. Both vinyl and cellulose acetate butyrate have excellent clarity and qualities for fabrication with automatic vacuum forming and electronic sealing equipment. These materials have limited use. When formed into blisters and subjected to low temperature and high humidity tests, the blisters exhibited embrittlement, cracking, and swelling.
