Such defects refers to the visible hole size 1.0 mm maximum. 2) Yellow spot means that the film becomes slightly yellow. 3) No wrinkle is allowed in the joint of each interface, 0.64m deep of adhesive tape required. 4) Rewinding hardness of the roll must keep consistent. Mark can be seen when pressing by hand. 5) Backing release paper colour must be the same. Yellow and white must be stored separately. Attention should be paid to the yellow back colour. No significant deviation is observed with eye. Size SizeNominateAllowanceWidth0.64MA class(±2mm)Qualified(±5mm)Length120MA class(±0.5m)Qualified(±1.2m) Note: 1) No hardness of roll is specified. 2) No edge offset is greater than 3mm allowed. Roll surface flatness is less than 0.5 mm. 3) Special specifications can be ordered. Colour variation in the samel batch (1) No big colour variation is observed against the colour disc. (2) If big colour variation is observed against the colour disc, .the whole batch must be specially treated.

A little blank in B area Note: 1) Pinhole means defect blank of hot stamping. 2) Stamping conditions: 2# (pressure), 125-130°c, 0.75 0.8s. 3) When stamping is completed, wipe the stamping pattern in the clearer stamping area (as a minor area of flying gold) by hand, observe the palm, judge the metal flakes left on palm. The less the better. 4) Hardness is different to that of card type H1XX. It is appropriate to take H1XX M type as H5XX M type. 5) Test frequency: One for every 10 standard sample printing roll. Exam if there is release paper what the hardness is. Product Model and Property Electrochemical aluminum is also called hot stamping foil. It is made by vacuum aluminum metalisation. Its basic structure is the base film layer, peel layer, dyeing layer, metalised aluminium layer and adhesive layer etc. Low costs, continuous mechanical hot stamping makes this technology rapid promotion in the fields of industry. Printing effect is more rich and colorful.
