The transparency of pet is good, and its transmittance can reach 90%. In the production process of polyester bottle manufacturers, the following factors affect the transparency of polyester bottle:
1. The moisture content of the material must be fully dried before production. Generally, the drying temperature is 160 ℃ for the dried materials. If it is stored in the air for a long time, it will not absorb moisture. Therefore, once the raw materials are dried, they must be used immediately or directly by the continuous dryer, otherwise they must be kept in the incubator at 90 ~ 100 ℃ for standby, so as to avoid moisture absorption again after drying
2. The wall storage of bottle blank will directly affect the transparency of the bottle. The reason is that the size of the wall storage directly affects the cooling process of the bottle blank. When the mold temperature is low, the wall storage can be appropriately increased, otherwise the wall thickness will be reduced.
3. When the burner at the bottom of the parison is narrower and the runner is narrower, the melt flow velocity will increase, which will promote the obvious crystallization phenomenon near the gate and produce an opacified layer. When the gate size or runner size is increased, the size of opacification layer will be reduced.
4. The viscosity of the melt directly affects the viscosity of the resin at the same melting temperature. It was found that the higher the viscosity of the resin melt, the greater the flow resistance and the thicker the opacification layer. According to the experience, the intrinsic viscosity of the resin will increase by 10 ℃ when the processing temperature increases by 0.1. Therefore, according to different resin viscosities, the resin must increase its melting temperature and the temperature of the mold gate to improve its fluidity.
Nowadays, many people will think of white for the first time when choosing the color of plastic bottles. White is really versatile and can be matched with any other color. However, many people hope that the color of product packaging will be more active and rich. Green is also a common color and looks more comfortable. What color will green match?Many people like the fresh and natural smell of green, but it’s difficult to grasp the color collocation except green in plastic bottles.
