What are the restrictions on the application of self-adhesive coated paper in medical packaging?

There are some restrictions on the application of self-adhesive coated paper in pharmaceutical packaging, which mainly come from the special requirements of the pharmaceutical industry and the consideration of the characteristics of self-adhesive coated paper. Here's a breakdown of these limitations:

First, special requirements of the pharmaceutical industry

1. Hygiene and safety:

The pharmaceutical industry has high requirements for the hygiene and safety of products. Self-adhesive coated paper needs to ensure that it does not contain harmful substances in the process of use, and will not chemically react with drugs, so as to avoid pollution of drugs or affect the quality of drugs.

The choice of adhesive is also critical to ensure that it is non-toxic, odorless, non-irritating, and will not spill or remain on the drug packaging during use, so as not to cause potential harm to the drug and the patient.

2. Durability and stability:

Pharmaceutical packaging needs to withstand various environmental conditions, such as temperature, humidity, light and so on. Self-adhesive coated paper needs to have good durability and stability to ensure that the label does not fall off, does not deform, and does not fade under various environmental conditions.

3. Automatic labeling requirements:

Automatic labeling equipment is widely used in modern pharmaceutical production lines, which requires self-adhesive coated paper to have good die-cutting performance and tensile strength to meet the needs of high-speed and accurate labeling.

Second, the characteristics of self-adhesive coated paper

1. Material characteristics:

Although the self-adhesive coated paper has good printing effect and visual effect, its surface material may be highly permeable to some drugs, and there is a risk of adhesive penetration. This requires that when selecting self-adhesive coated paper, special attention needs to be paid to its permeability to avoid contamination of drugs.

2. Printing and processing restrictions:

Although the printing effect of self-adhesive coated paper is excellent, in some special printing requirements (such as the need to achieve anti-counterfeiting functions, special effects, etc.), it may be necessary to use more complex printing processes or special materials, thereby increasing the cost and processing difficulty.

Third, application examples and solutions

Bottle label: In pharmaceutical packaging, self-adhesive coated paper is mainly used to make bottle label. These labels need to clearly display key content such as drug information and instructions for use. In order to ensure the fastness and durability of the label, a self-adhesive coated paper material with good tensile strength and excellent die-cutting performance is usually selected.

Sealing label: Self-adhesive coated paper can also be used to make sealing labels to ensure the tightness and integrity of pharmaceutical packaging. In order to meet the needs of automated labeling, these labels need to have good die-cutting performance and strippability.

Special needs solution: For the special requirements of the pharmaceutical industry, self-adhesive label suppliers can provide customized solutions. For example, for permeability problems, low or no permeability adhesives can be developed; For anti-counterfeiting needs, we can provide special materials such as fragile paper, font anti-counterfeiting labels.

In summary, the application of self-adhesive coated paper in pharmaceutical packaging is affected by the special requirements of the pharmaceutical industry and its own characteristics. In order to meet these requirements and overcome limiting factors, it is necessary to select suitable self-adhesive materials, adhesives and adopt reasonable printing and processing processes. At the same time, with the continuous development of the pharmaceutical industry and technological progress, the application of self-adhesive labels in pharmaceutical packaging will continue to be optimized and improved.
