4 Physical properties of window cards
4.1 Materials
The materials used to make window cards are in accordance with B/T 39013 (reference paper); 4.2 Characteristics of openings
The size and position of the window in the card are shown in the figure below. 1

Figure 2 Adhesive tape of adhesive structure 4.3.3 Adhesion of adhesive tape protective paper
B/117739.3—2004
Before placing the microfilm on the opening card, a semi-transparent or opaque adhesive tape is pasted on the bottom of the opening card. The adhesive tape protective paper and the commercial hole adhesion test should meet the requirements of TSC6343:1981: to enable the protective paper to be removed by hand or by dynamic method.
Student: The width of the adhesive section increases with the increase of the time, and the removal of the protective plate will become more difficult. 4.3.4 Thickening
The thickness refers to the difference between the thickness of the card itself and the total thickness of the card after processing. According to the method of 5, the thickness should not exceed 1000 mm. 4.4 Envelope-type window card
4.4.1 As mentioned above, the surface of the envelope-type window card has a supporting sheet to form an envelope with a hole: the sheet is fixed in this envelope, and the supporting sheet should be made of a colorless and transparent thin film. 4.4.2 Position of the supporting sheet
The position and size of the supporting sheet should be as shown in the figure. The single is m

A.1 Shape and cut angle of angle
(Informative Appendix)
Window card. Angle and color
The card should have one angle and
a closed angle. From the card! If the angle is good, I can also be on the right. A.2 Unique microfilms shall be distinguished by printing the same colour or by printing the lower part with a colour mark. A.3 Colour mark The colour mark may be placed at any position on the card. If the microfilm is monochromatic, the most effective method is to print the colour mark at 6.5cm below the top of the card. The colour mark should be printed on the lower part of the card without any obvious reverse thickness. 4 [1] 1S(32721:1983 GB/T 1//33.3—20C4
