Talking about the four bag making methods of PE stretch film plastic packaging

1. The three-side seal is to seal around the packaging bag. The size of the front and back are both the size of the finished product. It has a certain sense of integrity, the design is not restricted, and the front and rear designs have a certain degree of continuity. Since the front and back have the same size, the front can be designed first so that the back and the front can echo each other. When making a plate, the front and the back should be arranged on the same registration cylinder.

2. The middle bottom seal is sealed on the back side. The size of the front side is the size of the finished product. The back side is divided into two equal parts, and the sum of their widths is equal to the width of the front side. Usually, the front side and the back side are unfolded for an integrated design during design, and Add 1cm edge banding on the left and right, and the front and back are also on the same registration cylinder.

3. The three-dimensional middle seal is based on the middle and bottom seal, adding three-dimensional edges on both sides, and the front, back, and side 3 sides are also on the same registration cylinder.

4. Due to the limitation of printing materials, the front and back of PE stretch film materials must be designed separately and plate-made separately, and cannot appear on the same registration cylinder at the same time.
