Polyester Labels, PP
  1. Scope. This specification covers polyester label including variations that are writable and/or have a lamination. Typical applications include hazardous materials labels such as PCB labels, RTK labels and test & calibration labels. The four variations described in this specification are:

    2. PM: standard label, not writable, no lamination
    PP: machine laminated with polyester
    W1: writable coating, no lamination
    WM: writable coating, self-laminating flap
    CO: writable coating with scratch-off pad and self-laminating flap

  2. Base Material. The base film shall be a 0.002" thick polyester film, ICI 329 or equivalent. The base film shall have a minimum thickness of 0.001" of a solvent-based, acrylic adhesive and a paper liner. The liner shall be a 90# type with a thickness of 0.007". The liner shall be backslit so that it can be easily removed. 
  3. Writable Coating [optional]. The base film shall have a writable coating that allows the customer to write his name, account number and address. The coating shall be receptive to marks from a pencil, ball-point pen or permanent marker. Pencil marks may be erased without damage to the coating. The coating shall have the following characteristics:
    Coating Weight 0.5 lbs per 1,000 sq ft (+/- 6%)
    Coating Thickness 0.0003" (+/-0.0001")
    Densitometer reading using GAM #126P and a 0.50" sq pencil mark on a square section of coating 1.14, HB Pencil 1.05, H Pencil 1.00, 2H Pencil
    Defacement of Writing Pencil marks of a 2H pencil cannot be rubbed off using hand pressure.

 

  1. Polyester Overlamination [optional "C0" and "WM" only]. The label shall be overlaminated with a 0.001" thick clear polyester film, ICI 054 or equivalent, having a 0.001" thick solvent-based acrylic adhesive.
  2. Polyester Self-Laminating Flap [optional]. The label shall have an overlaminating flap made of a 0.002" clear polyester film, ICI 054 or equivalent, with a 0.0011" thick solvent-based acrylic adhesive. The flap shall be pressure sealed at one edge of the label. The part of the overlaminating flap not pressure sealed shall have a 90 pound white paper liner.
  3. Physical Characteristics. The material shall have the following minimum characteristics:
     
    4. Property Results
    Elongation at Break (ASTM D882) 110%
    Folding Endurance (ASTM D2176) 50,000 cycles
    Tear Strength Initiation (ASTM D1004) 900 g/mil
    Tear Strength Propagation (ASTM D1938) 12 g/mil
    Tensile Strength (ASTM D882) 28,000 psi
    Application Temperature 45ºF
    Operating Temperature -40ºF to 260ºF

 

  1. Ink Color & Printing: Conventional solvent-base or UV inks shall be used. The printing type style shall be Clearview, Helvetica or Univers. For "CO" labels, the scratch-off pad shall be removable with an ordinary pencil eraser.  
  2. Adhesive Performance. The base material shall be a 0.001" thick acrylic adhesive having the following minimum values:
  • Peel Strength (PSTC #1 at 70ºF and a 72 hour dwell)
    on Stainless Steel 80 ounces/inch of width
    on Polyester 70 ounces/inch of width
  • Shear Strength (PSTC #7 at 70ºF) 20 hours
  1. Weathering. After 500 hours of exposure in a QUV weathering deck the label shall remain adhered and readable. Sample of weathered and printed label shall remain on file at label manufacturer and is available for review by the customer.  
  2. Chemical Resistance. The material shall have the following resistance to exposure:
     
    3. Chemical PM, WM Rating W1, PP, CO Rating
    Mild Acids good excellent
    Mild Alkalines & Salt Excellent excellent
    Water Excellent excellent
    Solvents Good excellent

 

  1. Size. The labels shall have the following dimensions: (choose one)

    2. 1" x 2"
    2" x 4"
    3" x 3"
    3" x 5"
    6" x 6"
    ____ x ____ [custom]

  2. Packaging. 25 labels shall be packaged in a polyethylene bag or vacuum formed package. Each bag or package shall be identified with the item description, inspector, date, quantity and part number. Bags or packages shall then be packaged in a corrugated carton 
  3. Installation. The labels shall be applied to a clean, dry surface. Use a 3M Scotchbrite pad (or equivalent) to remove any surface oxidation, dirt or paint chalking from application surface and to rough up the surface. After this treatment the surface shall be cleaned with Surface Prep 77 or equal. Labels shall be applied at temperatures above 45ºF. 
  4. Warranty. Workmanship and quality shall be such that all lettering is sharp, legible, straight, and aligned properly. Smudges, misalignment, miss-wording, misspelling, crooked letters, incorrect color, incorrect materials, and any other problems that show poor quality and workmanship will give sufficient cause to reject any label. The products are to be guaranteed by the vendor to be free of workmanship or material defect.
