In the selection of plastic packaging containers, it is appropriate to have a general understanding of the various molding methods. The characteristics of various plastics commonly used in plastic packaging containers are very important for the correct selection of plastic packaging containers. Due to the raw materials of plastic packaging containers, the basic characteristics of plastic packaging containers are determined. Plastic packaging containers of the same or similar form may have extremely large differences in performance depending on the raw materials. Polycarbonate blow molded bottles and general polyester stretch blow molded bottles have extremely good transparency and gloss, which are very similar in appearance, but polycarbonate bottles have excellent high temperature resistance but poor insulation properties. The general polyester stretch blow molding bottle has good insulation performance, but the heat resistance is poor.
For the incoming filling, the cover and the product supported by the barrel should be inspected first, otherwise the lid and the barrel will not match, which will easily lead to liquid leakage. During the process, please do not drag the bucket directly on the ground to avoid bottom wear and scratches. The correct way is to lift your hands or ship them from the forklift pallet. Pay attention to the filling, the liquid temperature can't be higher than 70 degrees, and the loading and transporting temperature should not exceed 25 degrees. It is forbidden to fill the plastic drum and transport it in high temperature liquid immediately after loading. It should also be stored in a clean, dry place to prevent contamination inside the barrel and avoid direct exposure to the sun.
The plastic barrels used should be lubricated inside and outside, no welding and seamless, and light weight, good strength, impact resistance, corrosion resistance, non-toxic and tasteless, and transportation is also very convenient.www.fhpails.com
