Aluminum foil pharmaceutical packaging

Aluminum foil pharmaceutical packaging

Aluminum foil pharmaceutical packaging is a very special commodity packaging which belongs to the field of packaging. First of all, it must have a variety of excellent packaging performance; second, must also have the ability to maintain the efficacy of drugs. With aluminum foil for pharmaceutical packaging, with beautiful, light, gas resistance, light resistance and other advantages, so that it is known as the star of drug packaging materials.

Aluminum foil has penetrated into every one of our lives

With the strengthening of people's awareness of health care, aluminum foil has penetrated into every one of our lives, in order to human health and is responsible for a major packaging mission.

The main factors that affect the heat sealing strength of aluminum foil pharmaceutical packaging

Raw and auxiliary materials

The original aluminum foil is the carrier of the adhesive layer, and its quality has a great influence on the heat sealing strength of the product. In particular, the original aluminum foil surface oil, will weaken the adhesion between the adhesive and the original aluminum foil. If the original aluminum foil surface oil and the surface tension is lower than 31 * 10-3 m, it is difficult to achieve the ideal heat sealing strength, so the quality of the original aluminum foil must be strictly.

Production process

Under the control of a certain process parameters, the adhesive is coated on the surface of the original aluminum foil, and the quality of the film can directly affect the sealing strength of the product. One of the most important parameters include the speed of coating, the temperature of the drying path, the shape of the roller, the depth, the number of lines and the position and angle of the scraper.

Heat seal temperature

Heat seal temperature is an important factor affecting the heat seal strength. The temperature is too low, can not make the bonding layer is very good with PVC film heat sealing, bonding layer and PVC film adhesive is not strong. If the temperature is too high, it will affect the drug. Therefore, the reasonable heat sealing temperature is usually between 150 and ~160.

Higher quality aluminum foil

In general, there are many factors that affect the heat sealing strength of aluminum foil packaging, and each aspect will affect the heat sealing strength of the product independently. Production enterprises should actively look for problems, each link with high standard, high requirement and technology to monitor the production, the only way to ensure the quality of the products on the market, and in a dominant position in the fierce competition, by the trust of users, to enable enterprises to obtain long-term development.
