What is Medical Cold Seal Paper?
The paper used for packaging bandages and wound dressings is called cold-seal paper. It is usually glassine paper, which has high density, is oil-resistant, moisture-resistant, and has a very smooth surface.
Cold-seal adhesive refers to an adhesive that does not require heat during packaging—the materials are sealed together simply through machine pressure. A key characteristic of cold-seal adhesive is that it only adheres to itself and does not stick to other products.
Applications of Cold Seal Paper in Medical Packaging
Our medical-grade cold seal paper is mainly used in the packaging of:
- medical tape packaging
- wound dressing packaging
- adhesive bandages packaging
Many factories choose cold seal paper not only because it is easy to seal, but also because it protects the adhesive layer of the product, reducing the risk of adhesion loss caused by high temperature sealing.

FAQs About Medical Cold Seal Paper
Q1 : What is the difference between cold-seal paper and heat-seal paper?
A: Cold-seal paper does not require heating, while heat-seal paper needs to be heated in order to bond.
Q2 : Can cold-seal paper replace heat-seal paper?
A: Depending on your production line, cold seal advantages include: no heat sealing equipment required, faster sealing speed, avoids adhesive aging caused by high temperatures, and energy-saving and simpler equipment. Cold seal advantages also include: the ability to withstand long-term high-temperature sterilization. Many medical tape and bandage manufacturers are switching from heat-seal to cold-seal due to lower costs and product protection advantages.
Q3 : Is medical cold seal paper suitable for sterilized products？
