Do you know the type of plastic packaging bags?
ã€China Packaging Bag Trading Network】 There are many types of plastic packaging bags, and the specifications are uncertain. Therefore, design and production staff often neglect the way of making bags. The result is that although the design draft is beautiful, the finished product packaging is unsatisfactory and even becomes a waste product. Experience tells us that only on the basis of understanding the types of commonly used packaging products can we fully develop the design ideas, eliminate design works that do not conform to the bag-making process, and design practical and perfect finished packaging. Plastic packaging bags can be divided into four categories: three-side seal, mid-bottom seal, three-dimensional middle seal and sheet material according to the method of making bags. The three-side seal is sealed around the packaging bag. The front and back dimensions are the finished size. It has a certain sense of overallity. The design is not constrained, and the front and rear designs have a certain consistency. Because the front and back dimensions are the same, the front can be designed first so that the back and the front echo. When making a plate, the front and back should be arranged on the same set of plate rollers. The midsole seal is sealed on the back, the front size is the finished size, the back is divided into two equal parts, and the sum of its width is equal to the width of the front, usually when designing, the front and back are unfolded, integrated design, and left and right Add 1cm edge banding each, and the front and back are also on the same set of plate rollers. The three-dimensional middle seal is based on the middle bottom seal, and three-dimensional edges are added on both sides, and the front and back sides are also on the same set of plate rollers. Due to the limitation of printing materials, the front and back sides of the sheet must be designed separately, and the plates should be made separately. They cannot appear on the same set of cylinders at the same time. If you have a need for packaging bags, you can go to the China Packaging Bags Trading Network.
