Description

Printed EVA bathroom toy and production line

Technical Field

The utility model belongs to the technical field of the toy, especially, relate to a printing EVA bathroom toy and production line.

Background

The existing EVA bathroom toy products are mainly three types:

1. the smooth EVA bathroom toy has no printing, single color and less design feeling.

2. The EVA surface is screen-printed on the toy, and the EVA surface is simply screen-printed on the toy. Due to the problems inherent in screen printing, the disadvantages are as follows:

2.1, mainly the color is simple and has no gradient;

2.2, under the multi-color design, a plurality of silk screen printing plates are needed, and the color matching error is large when the printing is not good;

2.3, screen printing ink is uneven, and a lot of ink can fade when meeting water due to insufficient adhesive force;

3. a film coated EVA bathroom toy. The product mainly takes EVA material as a substrate, and the surface of the product is covered with a printed BOPP film, and the defects of the material are as follows:

3.1, the BOPP film material is used for gravure printing, and the cost of a printing mold is extremely high. The mold of a single color is 900 yuan more. A single design will typically use 8-15 colors. The cost of a single design of printing dies would be 7200-13500 RMB. Many small and medium-sized customers cannot afford such high cost of the printing mold. Under the premise of the mold cost, manufacturers often reduce the special color molds to reduce the cost, but the printing effect is greatly reduced, so that the market has very low good appraisal rate on the product quality.

3.2 BOPP films, very thin due to the material properties of the film itself. The thickness is generally about 0.02-0.03 mm. Stretching through a printing machine while the product is compounded to EVA through high temperature ultimately results in very high error rates of the product. The reject rate of the final product is also very high. Resulting in a new and significant increase in production data loss.

3.3, the BOPP film has high mould cost and high printing order, and the order is 3000 meters generally. According to the size of the conventional product on the market, the same design is adopted, and about 12000-20000 sleeves can be produced from 3000 m materials. In the large market environment where new design and individuation are pursued at present, the product is difficult to gain market favor.

3.4, the BOPP film and the EVA are compounded through high temperature combination, and certain viscosity of the BOPP film after being heated is utilized. But after being made into a bathroom toy, the toy is put into a bathtub for playing by children. The temperature of the bath water is generally between 35 and 40 ℃. Meanwhile, the playing process of children is not enjoyed, but the children may be bitten by mouth and torn by hands. In such cases, the bond between the film and the EVA is not strong and can easily tear over time, eventually resulting in damage to the product and serious potential for misuse by small children.
