There are many kinds of bottom materials and surrounding materials for EVA storage boxes, which are mainly determined according to the effect and the requirements of the process. Here, the editor of the Xinyu handbag manufacturer lists several commonly done:

      1. If you ride a side car after folding the bottom of the bag, the bottom support is generally at least 6 mm. Without the paper mouth, the length of the supporting material is half less than the requirement of the drawing.

      2. If the front and back panels are reversed, the bottom bracket is 2 minutes smaller than the required size and width, and the length is half a minute less than the drawing requirements.

      3. If the bottom part is made of two pieces of carts and the sides are divided into one piece, you can add material after the cart is finished. The bottom bracket is 2 minutes smaller than the required size and width, and the length is half less than the drawing requirements.

      4. If the two ends of the bottom are folded and the side wall is folded, there must be paper openings on both ends of the bottom of the bag. However, this approach is rarely recommended.

      5. High-end EVA storage box has a kind of soft leather support bottom: bag bottom leather + 8 mm imitation lining cloth + 90 grams of non-woven fabric. The imitation lining is non-woven on the surface, and then the edges are glued to the bottom, and the imitation lining does not sweep glue in the middle.
