Embodiment Construction

[0020] A kind of manufacture method of paper cup material of the present invention, comprises the following steps:

[0021] The first step is to use food-grade white cardboard for food packaging as the base material;

[0022] In the second step, the PET (polyethylene terephthalate) aluminum-coated film is adhered to the front of the food-grade white cardboard with high-temperature resistant and environmentally friendly glue;

[0023] Food-grade white cardboard with PET aluminum-coated film adhered, which can not be deformed when forming at high temperature;

[0024] PET aluminum-coated film is coated with aluminum powder on the back of the PET film (that is, the contact surface with food-grade white cardboard), and the front of the PET film is used to print color patterns, so that the product can have a simulated metal material;

[0025] The third step is to use high-temperature-resistant composite ink to print the pattern on the PET aluminum-coated film at a temperature abov...

Abstract

The invention discloses a method for manufacturing a paper cup material. The method comprises the following steps of: 1, taking food-level white cardboard for food package as a base material; 2, sticking a polyethylene terephthalate (PET) aluminum coating film on the front surface of the food-level white cardboard by high-temperature-resistant environmentally-friendly glue; 3, printing patterns on the PET aluminum coating film by high-temperature-resistant composite ink at a temperature being more than 150 DEG C; 4, sticking a PET coverage film on the PET aluminum coating film printed by the ink by adopting transparent composite glue; 5, coating a first layer of polyethylene (PE) spraying film on the back surface of the food-level white cardboard; 6, sticking aluminum foil material paper on the first layer of PE spraying film; and 7, sticking a second layer of PE spraying film on the aluminum foil material paper. A paper cup made of the material has a good printing effect and high quality; and the sense of metal is strong.
