American made Doculam hot laminating roll film 27" x 500' x 1.5 mil on 1" diameter cores with glossy finish represents quality lamination rolls for thermal roll laminators. Overall diameter is approximately 3.6" inches and fits most roll laminating machines on the market using 1" diameter feed roll mandrels. Doculam is polyester based with high melt adhesive design typically used for two side laminating and has a standard polyethylene adhesive layer typically wound toward the inside of the roll. Polyester (PET) plastic films resist penetration by chemicals, greases, and oils and are the most commonly used laminate for hot roll laminators, especially when encapsulating paper sheets. Doculam is proudly made in the USA by Adlam Films, formerly Bryce Corporation, and is likely the most widely used American Made product designed for laminating plain paper with low ink coverage. Doculam is commonly referred to as very clear and flat school film.
