The quality of drug ایلومینیم ورق کی پیکیجنگ is related to people’s health, and for Aluminum foil packaging samples, the heat sealing strength of the product also largely determines the quality of the package. Through the analysis of production data of ہواوے ایلومینیم, we have also obtained some factors that will affect the heat sealing strength of Aluminum foil drug packaging.
1. Raw materials of aluminum foil filled with medicine foil
In order to improve the characteristics of aluminum in a certain aspect, aluminum foil manufacturers will add auxiliary materials to raw materials, or carry out composite processing of mixed layers. The original aluminum foil material is the carrier of the adhesive layer, the quality of the raw material directly affects the heat sealing strength of the product. If there is oil pollution on the surface of the original aluminum foil, it will weaken the adhesion between the adhesive and the original aluminum foil. اس معاملے میں, it is difficult to achieve the expected heat sealing strength, so the quality of the original aluminum foil is a problem at the beginning.
2. Use of adhesive
The adhesive is a special material with solvent, its role is to use the execution of production process, coated in the dark side of the original aluminum foil (or smooth), the formation of adhesive layer after drying, this process plays a decisive role in the heat sealing strength of the product. Adhesive color can be divided into colorless transparent, gold, and color series, most manufacturers can be produced according to customer needs. With different components of adhesive, the final product heat sealing strength will be different.
3. Production process of the product
Aluminum foil in the production process needs to adjust a lot of product parameters, a little error in the finished product may be different. Under the control of certain process parameters, the adhesive can be coated on the surface of the original aluminum foil into a layer of foil film, and the quality of the film will directly affect the heat sealing strength of the product. There are several key parameters. سب سے پہلے, the speed of coating determines the drying time of the coating in the drying channel. The speed too fast drying channel under high temperature will make the solvent volatilize on the surface of the film too fast, resulting in the residual solvent in the film. The film is not dry enough, and it is difficult to form a dry strong, and firm adhesive layer, which will certainly affect the heat sealing strength of the product. Secondly, the shape, depth, and scraper position, Angle determines the thickness and uniformity of the coating film. If these parameters are not selected or adjusted properly, the adhesive is difficult to evenly spread on the surface of the original aluminum foil, which will lead to uneven film formation and can not achieve a good heat sealing effect.

4. Temperature of heat sealing
The heat seal temperature is a critical step. If the temperature is too low, the bonding effect of the adhesive layer and PVC film is not very good, the bonding between the adhesive layer and PVC film is not strong. If the temperature is too high, the medicine will be affected.
5. Heat seal pressure
Only certain heat sealing pressure can achieve the ideal heat sealing strength. Insufficient pressure, so that the adhesive layer of the product and پیویسی فلم heat sealing is not sufficient, easy to produce bubbles in the middle, can not achieve a good heat sealing effect.
6. Product heat sealing time
Generally speaking, if other conditions are the same, a longer heat sealing time can make the heat sealing part more firmly sealed. صرف پیداوار کے عمل سے تفصیلات کو کنٹرول کرنے کے لئے, with the progress of technical means and production conditions of the limitation of modern high-speed drug packaging machine process conditions can not provide a long time to heat sealing. عام طور پر استعمال شدہ ایلومینیم فوائل چھالا, the scientific heat sealing time is 1s.
There are many factors affecting the strength of aluminum foil drug packaging and heat sealing, and each aspect is a very important factor. Want to do better in this respect, requires the production enterprises to be good at actively looking for problems, with high standards, high requirements, and high-tech to monitor each link of production.
