The production process of environmental protection bags: choose fabrics-planting, cutting, cutting-drawing-printing-sewing-packaging.
A detailed description
1. After receiving an order for an environmentally friendly bag, the first step is to choose the fabric. Good fabric can add a lot to the environmentally friendly shopping bag produced. The fabric should first choose the surface that has no surface, the vertical and horizontal tensile differences are small, and the feel is Harder non-woven fabric. The choice of fabric weight should be practical.
Sometimes the surface of the fabric should be shiny. The surface of the fabric is shiny, so that in preparation for the later printing, one is good printing, and the other is the effect of printing. In this way, the overall effect will be very prominent, such shopping bags will certainly be deeply loved by consumers.
Sometimes the choice of fabric feels harder. The harder fabric can stand up and stand up, highlighting the overall feeling of the environmental protection shopping bag. It is very practical. When I shop, put a certain weight of objects, it will not break or be damaged. Safe and practical, this is the standard for shopping bags.
Similarly, the requirement for small differences in the vertical and horizontal tensile strength of the fabric is also to ensure that the shopping bag has excellent performance in load-bearing.
2. The fabric is well produced and put in the warehouse. The next thing is how to make these large rolls of non-woven fabric into bags, and plant it into small pieces.
An environmentally friendly shopping bag is equivalent to a three-dimensional cuboid or cube. Well, it has six sides, of which the top is empty, so the shopping bag actually has only five sides, a large side before and after, two left and right sides, plus a bottom side. What we are talking about here is the sewing method for making shopping bags, which is different from ultrasonic bag making.
According to the size, we use automatic slicing machine and strip cutting machine to divide the fabric into small pieces of fabric of the size we need. Among them, the large slice is the three-sided conjoined body with the bottom before and after printing. Then there is the side, carrying hands, and wrapping the side strips. This is called strip cutting, and it refers to this type of handle and edging. Because they are very narrow, they must be cut into very small strips to match the processing of the finished product.
3. Printing. Generally, screen printing is used. Because it is a piece of pure hand printing, his speed and progress will be slower than that of machine printing. Of course, the cost will be higher than that of machine printing, but it The advantages are also very obvious, can print a small amount, the error rate is relatively low.
When printing, pay attention to the printed text, the pattern must have a good fullness, and the size of the grasp must be able to highlight the effect of the entire shopping bag.
4. Sewing. According to certain specifications and styles, like sewing clothes, sewing large pieces of fabric, small pieces, carrying hands, wrapping and other fabrics together has become the shopping bag of finished products we have seen.
This includes a lot of sewing methods, for example, at the interface of the handle and the large piece, it is necessary to not cross the cross, and the cross is to increase the firmness. On the side are a few lines, the length of the strap and so on.
5. Packaging. We use carton boxes according to certain specifications, 100 boxes or 200 boxes, and the boxes are printed with fonts. In this way, the finished shopping bags of one box are transported through logistics and sold to consumers at various terminals.
The development of eco-bags now has many styles, and the workmanship and process of each style are slightly different. The general manufacturing method is as described above.
