GENERAL INFORMATION

*** DISCONTINUED 5/23 SUGGESTED ALTERNATES 9457 OR 9458 *** A 1.0 mil. laminating tape featuring #320 hi-tenacity acrylic adhesive on a densified paper liner used for label applications. 9447 tape is specially designed for use with 3M Label Component Systems for protected graphics printing of polyester films. It also can be used in constructing custom tamper-indicating labels. #320 adhesive is used for general purpose applications and offers excellent flagging resistance and adhesion to a variety of substrates. Meanwhile, the kraft liner provides an ideal surface for rotary die-cutting. 9447 tape is a component in the construction of labels with protected or sub-surface printed graphics, used in harsh environments such as automotive (under the hood) or outdoor environments. See 3M data sheet for Environmental Performance (chemical tests) chart.

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.
It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.
Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.
Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
