General performance requirements of bottled tablets

For water bottles, tablets should be low in heavy metals, good in hue, stable in viscosity, good in transparency, low in thermal degradation and low in acetaldehyde content during bottle making, so as to ensure the unique taste of all kinds of water.

For oil bottles, generally, because of their large capacity and thick walls, oil bottle tablets must have suitable crystallization properties in addition to the requirements of hygiene and strength to ensure the transparency of the bottle blank and bottle body; In addition, the general edible oil has a certain brownish yellow color, and the color of the bottle pieces must match it.

For hot-filled bottles, the bottle tablets should be low in heavy metal content, low in acetaldehyde content, good in hue and stable in viscosity. When heat-setting treatment is carried out under the general working conditions of bottle-making machine, high induced orientation rate and stable crystallization performance must be required to ensure low shrinkage and small deformation of products during hot-filling.

For carbonated beverage bottles, in addition to hygiene requirements, due to the high filling speed and high inflation pressure, the products need to have high mechanical strength and appropriate crystallization performance.
