1, smell. In general engineering plastics, living plastics have no pungent odor, such as PP, PE, PC, PS, etc. If there is an unpleasant smell in the lid bucket and it is very irritating, then don't buy it. It is most likely made of secondary material and recycled material.
2, color selection. Requires bright colors and no color difference. It is best to choose a transparent color, followed by a single bright color. Do not choose black, because black is easy to add secondary materials, recycled materials, but it is difficult to distinguish.
3. Price selection. The plastic barrels produced by general raw materials have relatively high relative costs, so the price will also be at the upper middle level. If the price is extremely low, then you don't have to think about the production of the difference, because the manufacturer can't do it at the cost.
4. Appearance selection. Touch the edges with your hands, there is no significant cloak, chamfering at each corner, not scratching your hands. The rubber surface is free from impurities and black spots. The appearance of the bucket is transparent and smooth, and the finish is good. In order to avoid inspection, many plastic buckets are coated with a thin layer of good material on the surface. The typical gold jade is ruined. It is necessary to pay attention to see if there is any possibility of water leakage.https://www.fhpails.com/
