 3M8421-White & 3M8422-Black are polyester tapes used in the photographic industry for pre-splicing of most photographic film during development processing. Excellent for most general wide web splicing. Excellent solvent and chemical resistance, especially those found in photographic processes. Sealing, labeling, protecting and edging where a higher tack crude rubber adhesive is desirable. 3M8422-Black tape is opaque to light and can work in systems having automatic sensors. Hot caustics will weaken backing  after prolonged immersion.

JM887 is a polyester film tape with a high temperature silicone adhesive designed to resist chemicals and heat degradation. Primarily used to affix the film leader to a plastic carrier while being fed through the roller transport processors. Leaves no adhesive residue on the leader card or the film; assuring consistent performance and reliability. Impervious to color chemistry. JM887’s controlled unwind permits easy manual application without breaking or tearing. 
JH645 Silver Mylar tape is a thin, reflective film coated with a dimensionally stable, long-term acrylic adhesive. Ideally suited for transparency and most slide masking applications. Temperature resistance up to 325F. 
Red Lithographer’s tape is used for pre-press stripping, edging and opaquing applications. Absorbs U.V. and short wave light. Translucent & easily repositionable. Will not curl or damage negatives upon removal. 
3M8464 is a polyester tape used to splice most photographic film to a plastic leader card for processing in one hour photo machines. Excellent solvent and chemical resistance, especially those found in photographic processes. 
3M616 ruby red translucent tape is optically transparent and photographically opaque. 3M616 is used for pre-press stripping, edging and opaquing applications. Absorbs U.V. and short wave light. Easily repositioned after application. Will not curl or damage negatives upon removal. Tape is qualified to meet military spec. MIL-T-40620A.
