Detailed explanation of recycling of plastic bucket

It can be used for hot filling, and the general temperature should not exceed 60 ℃. After hot filling, the cover and stacking shall not be closed until the contents have cooled sufficiently and dropped to room temperature. If it is filled with easily dispersed chemicals, it can be equipped with a cover with exhaust function to avoid the risk of overpressure during transportation, and at the same time, it can ensure the sealing function of the liquid.

Temperature issues. Generally, the plastic bucket products are made of PVC. At a higher temperature, such as about 50 ℃, hydrogen chloride gas will be slowly decomposed, which is harmful to human body. Therefore, the plastic bucket products made of PVC cannot be used to hold food and drinking water. In addition, no matter what kind of material is made, the products of plastic bucket manufacturers cannot be used at too high or too low temperature to prevent deformation and other problems.

Weight issues. Plastic bucket products have a certain weight bearing capacity planning, assuming that too heavy storage will lead to embrittlement and deformation. Take back the problem. Plastic bucket products can be recovered, which can save some costs. However, it should be noted that the recovered plastic bucket products are only for industrial use and are definitely not allowed to be used as food packaging.

The plastic bucket with high light transmittance must be more strict with its surface quality requirements, without any defects such as mottling, air hole, whitening, fog halo, black spot, discoloration, poor gloss, etc. it must have certain strength and wear resistance, be able to resist impact, have good heat-resistant parts, have excellent chemical resistance, and have small water absorption rate. As long as it can be used in this way, it can meet the requirements of transparency and remain unchanged for a long time. Therefore, in the whole process of injection molding, we should pay attention to the planning of raw materials, equipment, molds and even products, and put forward strict or even special requirements.
