aluminum collapsible tube is useful

As a common packaging material, aluminum collapsible tube is not only because it has relatively high airtightness, oxidation resistance and corrosion resistance, but also because it can effectively isolate oxygen, odor, sunlight, and ultraviolet rays. The important thing is that it is non-toxic and odorless. Therefore, it is widely used in cosmetic packaging, pharmaceutical packaging, chemical ointment packaging, etc., for filling hand cream, hair dye cream, glue, ointment, paint, etc.

After the aluminum collapsible tube is stamped and formed, there are multiple processing procedures such as internal spraying, primer, printing, tailing glue, tail sealing, and top cover. But not all packaging aluminum tubes need to go through all these processes. Which processing procedure should be used for aluminum collapsible tubes is determined by the properties of the filling contents and the requirements of product design. The following is based on some daily problems to deepen everyone's understanding of the aluminum collapsible tube processing process.

1. Which products of aluminum collapsible tubes need inner spraying?

Answer: Products that are highly corrosive, sensitive and easily deteriorated, and easily react with metals, such as glue with strong acidity. Because the raw material used in the internal spraying is mainly epoxy phenolic resin, which can prevent corrosion, oxidation, and fall off;

2. Which products of aluminum tubes need to be primed?

Answer: The primer mainly uses saturated polyester resin to form a protective film on the surface of the aluminum tube to prevent oxidation and corrosion of the aluminum material. Aluminum tube packaging for cosmetics, hair dye cream, etc., plus primer, can make the printing effect better;

3. Which product packaging aluminum tubes need to be printed?

Answer: The printing mainly includes offset printing, silk printing, etc., which are mainly determined according to the design requirements of the product. For packaging of cosmetics and pigments, printing is added to attract more consumers in order to be more beautiful;

4. Which products of aluminum tubes need tail glue?

Answer: The function of the tail glue is mainly to enhance the sealing performance after sealing, prevent the ointment from leaking, isolate the content from contact with air and moisture, and ensure the shelf life of the ointment. Therefore, it is a product that is more water-like and leaks easily. For example: glass glue, cosmetics, you need to add tail glue;

5. Which packaging aluminum tubes need to be double-folded?

Answer: Those quick-drying glass glue and AB glue. Double-layer sealing makes better sealing performance.

Although the processing procedures of aluminum collapsible tubes are not high-tech, to manufacture high-quality aluminum tubes for packaging, every process must be paid attention to, so that the finished product after filling can be perfectly presented to consumers.

Second, the characteristics of the medical ointment aluminum tube clean room

Three, summary

1. What is a clean room for medicine packaging materials

Pharmaceutical packaging material clean room refers to the production environment where pharmaceutical packaging material manufacturers determine the corresponding cleanliness level according to the classification and use of the product, and set the corresponding cleanliness level to ensure that the product meets the specified production environment. The compressed air or various gases used in the clean room (area) should also be included in the controlled range.

Direct contact with the production of pharmaceutical packaging materials and containers, and adopt production techniques that reduce pollution to a minimum. The cleanliness level of the production environment needs to be considered. When the production technology cannot guarantee that the pharmaceutical packaging materials are not polluted, the cleanliness of the production environment should be improved as far as possible under the premise of conditions permitting.

Second, the characteristics of the clean room for pharmaceutical packaging materials

1. The cleanliness level setting should follow the same principle as the production cleanliness level of the packaged drugs, and the design and construction of the purification plant should be combined with the production process of the drug packaging materials to ensure that the products are produced in an environment that meets the requirements.

2. When there are multiple processes in the clean room (area), different cleanliness levels should be adopted according to the different requirements of each process.

3. The compressed air or various gases used in the clean room (area) are also constantly monitored to see if they are within the standard range.

4. The washing and drying of clean work clothes and the cleaning and storage of tools should comply with the corresponding regulations in the 'Pharmaceutical Production Quality Management Regulations'. The arrangement and storage of sterile work clothes after sterilization should be in a class 10000 clean room (area).

5. Different cleanliness levels should be equipped with buffer areas for changing clothes and shoes. To enter the aseptic core area of ??personnel and process materials, priority should be given to the process of gradual increase in several cleanliness levels to adapt to the different requirements of the area they want to enter.

6. The production area of ??a pharmaceutical packaging material enterprise can be divided into a production control area and a clean room (area). The production control area should be a closed space with a centralized air supply system with coarse-efficiency filtration. The inner surface should be smooth and smooth without particles falling off. Walls and floors can withstand cleaning and disinfection to reduce the accumulation of dust.

Three, the characteristics of the medical ointment aluminum tube clean room

1. The cold extrusion and shaping (punch, thread) process of the aluminum tube for medicinal ointment has corresponding dust-catching equipment;

2. The inner coating, curing, primer coating, primer drying, printing, and printing drying of the aluminum tube of medicinal ointment are all carried out in a Class D clean environment;

3. The capping, tail coating, and inner packaging of the drug packaging materials used for packaging sterile preparations should be carried out in a Class C clean environment. (Class D is a clean area of ??100,000, and Class C is a clean area of ??10,000)


Four, summary

1. In general, the clean room requirements for the production of medicinal ointment aluminum tubes are to be carried out in a class D clean environment, which is what we often call a 300,000 class dust-free workshop.

2. When there are multiple processes in the clean room (area), different cleanliness levels can be used according to the different requirements of each process. The upper cover, tail coating and finished product packaging of the medicinal ointment aluminum tube can be used in a C-level clean environment. Proceed down,

3. The clean work clothes of the aluminum tube of medicinal ointment are consistent with the specifications of the clean work clothes of other medicine packaging materials, and the washing and drying, cleaning and storage of tools conform to the corresponding regulations in the 'Pharmaceutical Production Quality Management Regulations'. The arrangement and storage of sterile work clothes after sterilization should be in a class 10000 clean room (area)

4. The production workshop of the aluminum tube for medicinal ointment is also divided into a production control area and a clean room (area). The production control area should be a closed space with a centralized air supply system with coarse filtration. The inner surface should be flat and smooth, without particles falling off. , The walls and floors can withstand cleaning and disinfection to reduce the accumulation of dust.

5. The inner surface of the medical packaging material clean room should be flat and smooth, with no particles falling off. Air, air pressure, microbiological control, and regular maintenance of the air supply system are not much different from the requirements of the medicinal ointment aluminum tube clean room.
