Improvements in glass bottle materials are expected to improve glass bottle performance

2022-04-27


It is reported that foreign professionals are developing new glass in the following two ways. The first is to change the material itself by changing the amount of a certain ingredient in the glass. Asolvex I glass, recently created by Saint-Gobain, is obtained by reducing the Al2O3 content in the glass bottle. The second is to apply a thin coating with auxiliary properties to the glass surface to improve its surface functional properties. In recent years, with the increasingly fierce competition in the packaging material market, the industry has higher and higher requirements for glass products. It is the general trend to improve the glass production process and develop new types of glass.

2022-04-27


Qingdao oral liquid bottle manufacturer testing method: 1. According to the system's tube selection classification standard, card board detection, weighing and weighing detection, the material selection and classification are carried out, and the tubes are divided into thin tubes, medium tubes and thick tubes. 2. To ensure the quality of raw materials, the raw materials are inspected strictly according to the standard requirements of physical and chemical properties, appearance, specifications and dimensions and other technical indicators. 3. The quality inspection department conducts in-house inspection and inspection of the products, and the quality assurance department is responsible for product quality qualification and pre-delivery inspection. 4. On the site of the bottle production workshop, self-inspection, mutual inspection, patrol inspection, and random inspection are carried out in strict accordance with the specifications, dimensions and appearance quality to ensure that the products meet the standard requirements. 5. After the product has been fully inspected, it will be sampled, and the product will be shipped out for factory inspection to ensure that the product quality meets the standard requirements. A big disadvantage of oral liquid bottles is that they are fragile, which affects the market share of oral liquid bottles. Now, when the glass bottle of oral liquid is manufactured, the brittleness will be greatly reduced after surface treatment. In the process of transportation, it is transported by a forklift to a long-distance truck, and from the forklift to the truck, which requires manual handling, but the glass bottle of oral liquid is heavy, and it is inevitable that bumps will occur during the transportation process, and it will be severely damaged during transportation. Vibration will increase the fragile rate of oral liquid glass bottles. In order to obtain customers, Qingdao oral liquid bottle manufacturers often need to provide the buyer with an additional number of brown bottles according to the broken rate, so as to ensure that the buyer can receive the complete glass bottle in the same quantity as the order after receiving the goods, which is virtually impossible. Increased the cost of Qingdao oral liquid bottle manufacturers. The current glass bottle business packaging is plastic-sealed glass bottles, plus carton, the purpose of this is to prevent the vibration of oral liquid glass bottles during transportation, and effectively prevent the collision between bottles and the resulting broken. There are also glass bottle companies that try to find direct/dedicated logistics when transporting over long distances to avoid damage to oral liquid glass bottles caused by multiple manual handling. This will greatly reduce the fragile rate of oral liquid glass bottles during transportation, and reduce the loss caused by the high broken rate of Qingdao oral liquid bottle manufacturers.

Glass injection bottles are the most common types of pharmaceutical packaging materials in clinical practice.

2022-04-27


Glass injection bottles are a common type of pharmaceutical packaging material in clinical practice. Due to the particularity of medicines, the country has stricter requirements on packaging materials. The stability of glass material is a very high-quality packaging material option for drugs that need to be stored for a period of time, so pharmaceutical glass injection bottles are more commonly used clinical drug carriers. The country has issued many standards and policies to standardize and require the quality of pharmaceutical glass injection bottles. Below, Qingdao injection bottle manufacturers combine the new standards for pharmaceutical packaging materials to explain which items need to be tested for pharmaceutical glass injection bottles. What testing instrument to use, the water resistance of glass particles is a routine testing item for glass products. 1. Beat the injection bottle into pieces, put an appropriate amount into the grinding bowl, insert the pestle, and slam the pestle once with a hammer. 2. Transfer the glass in the grinding bowl to the O sieve on the upper layer of the sieve, and repeat the above operation process. 3. Vibrate the sieve with a vibrating screen machine (or shake the sieve manually) for 5 minutes. 4. Transfer the glass particles that pass through the A sieve but remain on the B sieve into the weighing bottle, if the amount is more than 10g, a total of 3 parts are prepared. 5. Use a magnet to remove the iron filings in each glass particle and transfer it into a 250ml conical flask. 6. Rotate and wash the particles of the injection bottle with absolute ethanol at least 6 times, 30ml each time, until the absolute ethanol is clear. 7. Heat the conical flask with glass particles on the electric hot plate to remove the residual absolute ethanol. 8. Transfer to an oven to dry, take it out, cool it in a desiccator, and store it for no more than 24 hours. The above is the testing method organized by Qingdao injection bottle manufacturers. I hope it will be helpful to you, and pay more attention when purchasing.

According to the survey, my country's veterinary drug bottle packaging demand ranks first in the world

According to the survey, my country's veterinary drug bottle packaging demand ranks first in the world. With the government's vigorous promotion of policies to improve the quality of domestic veterinary drugs, the development of veterinary drug bottle manufacturers is also increasing. Because the traditional glass bottle has a high breakage rate, and the inner plug of the glass bottle is not tightly sealed, it is easier to leak, and it will also lead to the accelerated growth of pests and bacteria. In addition, glass bottles are difficult to recycle, which increases the cost of transportation. When plastic bottles are produced by veterinary drug bottle manufacturers, the use of glass bottles is completely replaced. With the development of our country's plastic industry, the veterinary medicine bottle packaging industry will have a very good development prospect. The good product performance and processing method of veterinary medicine bottles are the reasons for their popularity, but when packaging, it is necessary to ensure that the plastic bottles have good pollution-free and cleanliness, and can show good use value in the process of use. The veterinary medicine bottle has high quality bottle quality. The injection blow molding process can not only ensure the consistency and accuracy of the wall thickness and quality of the tube blank, but also ensure the high resistance to permeation, high sealing performance and high quality of the bottle. Appearance properties and sufficient physical and mechanical properties. It makes the bottle mouth more beautiful and tidy, without slope peaks and scraps, the thread size is relatively stable, and the precision is high, the mechanical strength is high, the gloss of the bottle body is relatively good, there are no flow marks and slip marks, and the parting line is very good. Well, there are no weld lines at the bottom of the bottle. The molding characteristics of veterinary medicine bottle: 1. Crystalline material, low moisture absorption, does not need to be fully dried, excellent fluidity, fluidity is sensitive to pressure, high pressure injection should be used during molding. The material temperature is uniform, the filling speed is fast, and the pressure is sufficient. Direct gates should not be used to prevent uneven shrinkage and increased internal stress. Pay attention to the selection of the gate position to prevent shrinkage and deformation. 2. The shrinkage range and shrinkage value are large, the directionality is obvious, and it is easy to deform and warp. The cooling speed should be slow, and the mold is equipped with a cold material cavity and a cooling system. 3. The heating time should not be too long, otherwise decomposition will occur. 4. When the soft plastic parts have shallow side grooves, they can be forcibly demolded. 5. Melt rupture may occur, and it is not suitable to contact with organic solvents to prevent cracking.
