Description

technical field

[0001] The invention relates to the technical field of plastic production, in particular to a processing technology for improving the transparency of plastic cups. Background technique

[0002] Plastic cups are commonly used utensils for drinking water in people's lives. Based on their light texture, beautiful appearance, low cost and strong plasticity, they are deeply loved by people.
