What are the domestic quality standards for circular color copperplate label paper?

The quality standards of circular colored copper plate label paper in China usually cover a number of aspects, and these standards are designed to ensure the quality, safety, environmental protection and overall compatibility with food packaging. The following are some of the main quality standard requirements:

First, material requirements

1. Paper material:

Coated paper materials that meet food safety standards should be used to ensure that they are non-toxic, harmless and will not pollute food.

2. Gram weight and thickness:

According to the specific needs to choose the appropriate weight and thickness, usually coated paper weight range between 70g/m² to 400g/m², the allowable deviation should meet the national standard.

Second, printing quality requirements

1. Color:

Printing color should be bright, uniform, consistent with the standard proof. The color between different batches should be consistent, and the color difference should be controlled within the allowable range.

2. Clarity:

Text, pattern should be clear and legible, line edge smooth, no blur, double shadow phenomenon.

3. Accurate overprint:

When multi-color printing, the overprinting of each color should be accurate and without dislocation.

Third, physical performance requirements

1. Wear resistance:

The label paper should have a certain wear resistance and be able to maintain the integrity of the printed content in the process of packaging, transportation, storage, etc.

2. Water resistance:

It should have a certain water resistance to prevent the label paper from absorbing water and deforming or ink falling off in a humid environment.

3. Adhesion:

The adhesive layer should have good adhesion to ensure that the label paper can be firmly pasted on the food packaging and is not easy to fall off.

Fourth, environmental protection requirements

1. Material environmental protection:

The label paper and its adhesive layer should be made of environmentally friendly materials and do not contain substances harmful to human health and the environment.

2. Recyclability:

The recyclability of the label paper should be considered to facilitate disposal and reuse after waste.

Fifth, other requirements

1. Label design:

Label design should comply with the requirements of relevant laws and regulations, including but not limited to food name, specifications, production date, shelf life, manufacturer information and other content.

2. Consistency:

Each batch of label paper should be consistent in terms of quality, specification, printing effect, etc.

It should be noted that the specific quality standards for circular color copperplate label paper in China may vary depending on the industry, use and local standards. Therefore, in practical applications, it is recommended to refer to the relevant industry standards, local standards or customer-specified standards to ensure that the quality of the label paper meets the requirements.

In addition, with the improvement of environmental awareness and the increase in consumer concern for food safety, the future requirements for the environmental protection and safety of circular color copperplate label paper may be more stringent. Therefore, production enterprises should constantly pay attention to changes in relevant regulations and standards during the production process, and timely adjust production processes and product formulations to meet market demand.
