Active pharmaceutical ingredients are classified into two major categories based on their source: chemically synthesized drugs and naturally derived chemical drugs.

What advantages do the materials used to manufacture medical adhesive‑coated paper have compared with those used for ordinary packaging bags? According to relevant experts, medical adhesive‑coated paper should be made from food‑grade cardboard and packaged in a paper‑based structure comprising polyethylene, paper, aluminum, and platinum. This represents a high‑tech method of food preservation: under sterile conditions—meaning that the package, the product being packaged, and all packaging equipment are sterile—the liquid food is filled into the package and sealed after a brief period.

1. The transparent film of medical adhesive‑coated paper consists of a multilayer composite structure, offering excellent bacterial barrier properties and long shelf life. It achieves an airtight seal when sealed under sealing pressures of 150–180 g/cm² and within the specified dwell time. Tests such as pyrogen testing, bacterial culture testing, and chemical indicator card testing have all demonstrated compliance with applicable requirements.

2. Medical adhesive-coated paper exhibits excellent permeability, allowing gases to pass through safely while effectively venting the cold air inside the pouch for enhanced performance. It also offers superior drainage: per square meter, the paper‑plastic packaging material weighs 56–70 g, and its drainage does not produce condensate from vaporized moisture. During low‑temperature drying and cooling, the paper maintains good tensile strength and remains free from cracking.

3. Beneath the medical adhesive‑coated paper, there is a pressure‑steam chemical color‑change indicator. This allows you to directly mark the paper with the title, date, expiration date, operator’s name, and inspector’s name, eliminating the need to affix chemical indicator tapes or various labels.

4. The use of medical adhesive‑coated paper has reduced the costs associated with various infrequently used bags and the consumption of supplies. In the past, because items were stored for short periods, expired materials had to be repackaged from scratch. Packaging required replacing sewing needles, threads, and blade tips, using clean wrapping cloths, inserting chemical indicator cards into the bags, affixing chemical indicator strips on the exterior, and incurring the full cost of adding a sterilization cartridge at the outset.

Compared with the types of surgical procedures and the increasing number of sterile packs, the control rates for many less‑common sterile packs remain relatively low; nevertheless, retrieving them during emergency situations continues to be time‑consuming and labor‑intensive for all clinical departments. Packaging with medical adhesive paper not only extends shelf life but also ensures ready availability for clinical use, eliminating the need for reprocessing and reducing consumable waste.

The fundamental causes of damage to medical adhesive-coated paper are as follows:

Plastic surface damage:

The primary cause is that sharps in medical adhesive‑coated paper packaging were not properly maintained, or the protective caps became detached, allowing the sharps to protrude through damaged packaging.

Scratched by an external object:

1. The primary and secondary causes are inadequate maintenance of sharp instruments or the loss of protective caps, resulting in these instruments puncturing the medical adhesive‑coated paper.

2. Scratches caused by foreign objects.

3. During routine tasks, staff members’ hands become wet when conducting self‑reflections or cleaning and disinfecting equipment cabinets, resulting in damp paper.

4. Improper handling by operators—such as picking up a corner or lifting heavy items—can damage the paper, resulting in tears in the medical adhesive-coated paper.
