Two pressure-sensitive adhesive layers 5 are 0.085mm, and release material layer 6 is 0.11mm.1.5mm foam tape：Easy following layer 1 is 0.005mm, foam
Layer 2 is 1.3mm, and the first pressure-sensitive adhesive layer 3 is 0.06mm, and submissive enhancement layer 4 is 0.05mm, and the second pressure-sensitive adhesive layer 5 is 0.085mm,
Release material layer 6 is 0.11mm.
Table 1
Note：Length is lost in coating materials, refers to causing to generate the cross-section print of coating materials outward by core because winding segment difference height influences
Length.
Comparative example 1
For most important foam density in foam tape, single factor test Optimal Experimental, such as table 2 are carried out.Prove 1.0mm bubbles
Celloidin band (consistent in its every layer thickness design and implementation example 1), in the case that other conditions are certain, foam density size and film
The relationship of material loss length, finds out the optimization scheme for reducing loss.
