Problems solved by technology

And this kind of cup has a solid medium to conduct heat, so the heat in the cup can be easily transferred to the outer wall, so the anti-scalding effect is relatively poor.

Embodiment approach

[0044] Such as Figure 1 to Figure 3 Shown is an embodiment of the paper cup production process of the present invention, comprising the following steps:

[0045] S1: Process the inner cup wall and compound with the cup bottom at the same time to form the cup body.

[0046] Wherein, the S1 processing procedure includes the following steps:

[0047] S11: Use base paper rolls for coating and die-cutting; cut a part of the bottom paper roll as the bottom roll of the cup; cut the other part into a fan shape as the inner cup wall;

[0048] The coating in this step adopts single-sided coating or double-sided coating. The inner wall of the cup body is coated with a film on one side, so that the inner wall of the cup can have the function of preventing moisture. The double-sided coating can protect both sides of the paper of the cup body, so that the cup has a better moisture-proof effect. In addition, in the process of holding water, the time of being wet by water increases.

Abstract

The invention discloses a paper cup manufacturing technique. A cup body is sleeved with an outer layer cup wall, an inner layer and an outer layer of a cup are formed, no glue exists between the two layers, accordingly a clearance exists between the inner layer cup wall and the outer layer cup wall, and the cup is more scald-proof since heat and humidity of the inner layer cup wall are insulated by the clearance when the cup contains water; and meanwhile, the situation that the cup body becomes soft and collapse due to the fact that the cup is prone to being soaked by water is avoided, and therefore, the paper cup manufactured through the technique can be firmer and better in scald-proof effect.

Description

technical field [0001] The present invention relates to a kind of production technology of environmental protection material, more specifically, it relates to a kind of production technology of paper cup. Background technique [0002] A paper cup is a kind of paper container made by mechanically processing and bonding base paper (white cardboard) made of chemical wood pulp, with a cup-shaped appearance. Waxed paper cups for frozen food, can hold ice cream, jam and butter, etc. Paper cups for hot drinks are coated with plastic, resistant to temperatures above 90°C, and can even be filled with water. Paper cups are characterized by safety, sanitation, lightness and convenience. It can be used in public places, hotels and restaurants, and it is a disposable product. [0003] The cup bodies in the prior art are all single-layer or multi-layer, and the walls of the multi-layer cup bodies are glued together, so that the inside and outside of the cup are relatively fastened, and...
