Since medical hot melt adhesives directly act on the surface of the human body, the standards and requirements for this type of hot melt adhesive are very high. So, what are the specific standards?
1. Adhesion
Different people have different skin types, such as dry and oily, thick and sparse body hair, smooth and rough. Human skin has a certain degree of breathability, but it also varies in terms of oiliness, sweating ability, dryness and other types. In view of these differences, when choosing adhesives, it is necessary to ensure the firmness of the bond and excellent durability. The material itself. Sensitivity and odor.

① The peel strength of medical hot melt adhesive should not be too high: The peel degree of hot melt adhesive should be maintained within a certain range. Excessive peel strength may cause skin tension and discomfort during use. There is pain and skin damage when tearing.
② Good initial adhesion: As the material is mostly used on or around wounds, it is not advisable to press hard. Hot melt adhesive requires good initial viscosity and is easy to adhere to the skin.
3. Hypoallergens
When using medical hot melt adhesive, it is required that it will not cause skin irritation, such as redness, itching and other allergic reactions.
4. Air permeability
Medical hot melt adhesive products need to have good air permeability, which can significantly reduce the occurrence of skin allergies. Maintaining permeability during the construction process also helps the skin sweat, keeps the wound dry, and has a positive effect on accelerating wound healing.
Conclusion first: Try not to mix the same batch number across seasons as much as possible Hot melt adhesive granulesThe performance fluctuates significantly with temperature. High temperature and humidity in summer, low temperature and dryness in winter, using the same adhesive can easily lead to “summer rebound and winter cracking”. It is recommended to switch […]
Why are more and more takeaway boxes being usedhot melt adhesivesealing Compared to tape,Hot melt adhesive granulesThe seal is clean, residue free, and can pass through automatic lines, making it particularly suitable for food contact packaging such as lunch boxes, paper cup covers, and handbags.

First, provide a reference scale Based on the estimation of 1 gram of glue consumption per common small and medium-sized cardboard box and single box, one tonHot melt adhesive granulesApproximately one million boxes can be sealed; A single box consumes 2 grams of glue, which is about 500000 pieces. The reason why the range is […]
Firstly, the conclusion is that the construction temperature of low-temperature hot melt adhesive particles is usually between 110-150 ℃, which is about 30 ℃ lower than that of ordinary adhesive particles (150-180 ℃). The advantages are energy saving, equipment protection, reduction of burns and smoke, and it is suitable for thin paper, thermal sensitive materials, […]
