Plastic drums will not dissolve harmful substances. PC, polycarbonate, PP, polypropylene and ABS are pan PIB-PS block copolymers. This material is non-toxic and its melting point is above 200 degrees. It will not decompose when boiling, but many additives will be added in the molding process, such as strengthening, toughening, anti-aging, anti-oxidation and plasticizer. These are non-toxic, Food grade plastic bucket The content of the additive is strictly limited, and it is easy to volatilize when released.
The number at the bottom of the plastic food bucket represents the material used: number 3: meaning: this number represents PVC. This material is hard and is usually used to make food boxes, water pipes and building materials. It is widely used in daily life. Use guide: The food box made of this material is only suitable for storing dry and low moisture foods, such as rice and pasta. PVC has no high temperature resistance. Therefore, before heating the food, transfer the food to a suitable container. Number 6: It means: this is the symbol of polystyrene. This material sometimes foams and is mainly used to make lunch boxes, water cups and tableware. Use guide: Among all types of food packaging materials, polystyrene has a low melting point. Although it can be used to hold warm food, do not heat the food box directly with this material. Number 7: meaning: this number refers to materials other than PVC and polystyrene or synthetic materials of various plastic materials. If the raw material of the food box is polycarbonate (including BPA), this figure will appear on the product. Use guide: This kind of food plastic bucket is made of various materials, and its heat resistance and storage method are also different. Before use, you must carefully read the product manual and strictly follow the manufacturer's instructions.
Performance characteristics of plastic drums containing different substances:
1. Manual horizontal rolling and horizontal rotation are also convenient for mechanical handling and wharf hoisting. It can contain a variety of Class II and III hazardous chemicals with a density below 1.4g/cm3, and has good anti-corrosion performance. At the same time, a variety of "O" rings are used to meet different filling requirements.
2. The dumped residue is small, easy to clean, and has a long service life. It can be used more than 20 times under normal filling, transportation and loading and unloading conditions. It not only saves energy, but also reduces the use cost.
3. The size meets the local container transportation requirements, and the stacking is convenient, safe and reliable. It can load 80 20 foot containers.
4. It can be used for hot filling, and the general temperature is not more than 60 ℃. After hot filling, do not close the lid and stack until the contents have completely cooled down to room temperature. Excellent weather resistance, from minus 50 ℃ to minus 40 ℃.
5. If there are easily decomposed chemicals, a cover with exhaust function can be equipped to avoid the risk of overpressure during transportation and ensure the sealing performance of the liquid.
To help you solve the problem, the plastic bucket manufacturer provides the following methods for you. I hope you can select Plastic bucket manufacturer Always have your own opinion.
1. To evaluate the qualification level of the plastic bucket manufacturer, the first step is to evaluate the qualification level of the plastic bucket, including the establishment period of the supplier. Generally speaking, the earlier the business license is issued, the higher its experience and reliability will be. Of course, the corresponding ISO9001 quality system certification and relevant product quality certificates are also guarantees to prove whether the manufacturer has the ability to manufacture good products. In addition, whether the supplier has relevant successful engineering cases and the supplier's after-sales service, such as the service life of plastic packaging barrels, warranty period, maintenance training, are very important considerations.
2. Investigate the skill level of plastic bucket manufacturers. Of course, there are high requirements for the technical level of plastic bucket manufacturers. For example, the plastic bucket must be able to withstand external forces. It can adapt to a variety of transportation modes and warehouse storage modes to protect the contents from damage. It must also have the function of protecting the contents from moisture, moisture, dust and corrosion. Of course, some humanized design is also necessary. For example, the bottle mouth of the chemical plastic bucket should be designed to be easy to open and can be opened and closed for many times. The contents shall be dumped conveniently and shall not injure people by splashing. I believe that if you consider the packaging barrel manufacturers from the above two aspects, you will make a more appropriate choice.
