2, high transparency, brittle feel, no toughness;

3, the size of the bag is tiled after the overall size of adhesive = width * length (CM). All the marked sizes are the overall length, the actual length is 2-5cm less than the overall length, small bags are 2-3cm, large bags are about 4-5cm, (the folded part of the sticker). For example, 10×15CM, the practical length is 10×12CM (3cm is the fold). In addition, this algorithm is not applicable to 4×6 5 x7 6 x 8 9×11 these smaller sizes), please calculate carefully before shooting, so as not to cause unnecessary trouble);

4, there are two kinds of bag side: 1, one side is flat, called flat knife, width will have about 1-2 mm error, accept the error to buy; (2), like film, side teeth, called flower knife, not easy to tear damage, so, flower knife actual use width to subtract 0.5 cm (such as 20*30 bag actual width is minus 0.5 cm is 19.5 cm) or so, please calculate good yo;
