5 liter plastic buckets will have labels when they are purchased. What should the manufacturer pay attention to when labeling? The following small series will explain for everyone:
When the label of the 5-liter plastic bucket is selected, the label surface should be flat. A “sash” can be planned on the exterior of the plastic barrel so that the label can be accurately positioned without moving. At the time of blow molding, the portion of the parison that inflates the touch always tends to be hardened first. Therefore, the wall thickness of the portion is also larger. The edge and the corner portion are the portions of the parison that are touched after inflation, and the wall thickness of the portion is small.
Longitudinal grooves or ribs eliminate the offset, sagging or deformation of a 5-liter plastic bucket under long-term load. The printed surface of the plastic bucket is the part of the customer's attention. The printed appearance should be flat and continuous. If the plastic bucket contains handles, grooves, ribs, etc., it should be noted that it is not convenient to make the printing operation. Elliptical plastic buckets are also stiffer, but molds are more expensive to manufacture. Therefore, in order to ensure the rigidity of the plastic barrel, in addition to selecting the material with high rigidity, the shape of the plastic barrel is planned to enhance the rigidity and load resistance of the plastic barrel.
