1. What are the common types of ointment packaging?

Ointment, also known as ointment, refers to a semi-solid pharmaceutical preparation with lipid or oily substances (such as petrolatum, lard, lanolin) used on the skin as a matrix, and an ointment for external use on the skin. Ointment packaging mainly refers to the container directly used to hold the ointment.

Commonly used ointment packaging are plastic ointment tubes, aluminum collapsible tube-plastic composite tubes, and pure aluminum collapsible tube hoses.

The plastic ointment tube is a synthetic high molecular polymer, which has the characteristics of light weight, impact resistance, and resistance to breakage.

The aluminum collapsible tube-plastic composite pipe is composed of two materials, plastic and aluminum collapsible tube, and the manufacturing process is more complicated and the air tightness is poor.

2. What are the performance characteristics of ointment packaging materials

1) Certain physical and mechanical properties

Packaging materials should be able to effectively protect the product. Therefore, it should have certain strength, toughness and elasticity to adapt to pressure and impact. Influence of static and dynamic factors such as vibration

2) Barrier performance

According to different requirements for product packaging, packaging materials should have a certain barrier to moisture, water vapor, gas, light, aroma, peculiar smell, heat, etc.

3) Better friction performance

The inner and outer sides of the packaging material have good slippery properties to ensure good opening and smooth transportation and packaging on high-speed production lines to meet the needs of high-speed packaging development of products.

4) Good safety performance

The toxicity of the packaging material itself should be low, so as not to contaminate the product and affect human health; the packaging material should be non-corrosive, and have the properties of insect resistance, moth prevention, rodent resistance, and microorganism inhibition to protect the safety of the product.

5) Appropriate processing performance

Packaging materials should be suitable for processing, easy to be made into a variety of packaging containers should be easy to mechanize and automate packaging operations to adapt to large-scale industrial production should be suitable for printing, easy to print packaging signs.

6) Better economic performance

Packaging materials should have a wide range of sources, convenient materials, and low cost. The used packaging materials and packaging containers should be easy to handle and not pollute the environment or cause public hazards.

7) Sealing performance

The sealing performance can ensure the integrity of the entire product packaging and prevent leakage, pollution, deterioration and other problems due to poor product sealing performance.

8) Less headspace

Controlling the gas composition inside the package is an important means to effectively extend the shelf life of the product or improve the quality of storage.

9) Low residual solvent

Ointment packaging uses a lot of solvents in the printing, compounding, and coating processes in the production process. These solvents are more or less left in the packaging materials. Packaging materials with higher solvent residues will endanger people's health.

Third, what are the performance characteristics of medical aluminum collapsible tube hoses

1) Corrosion resistance and good airtightness.

The surface of aluminum collapsible tube and its alloys is easy to form a dense oxide protective film, which can effectively isolate water vapor, oxygen, etc., and prevent the product from being corroded during circulation and use; and aluminum collapsible tube packaging with tail glue , It has better sealing characteristics, and has a more adequate sealing protection effect on the medicine inside.

2) Good processing performance and strong plasticity.

The density of pure aluminum collapsible tube is only 2.7g/cm3, which is a light metal, which can be processed by various casting methods and is easy to shape; aluminum collapsible tube has a simple manufacturing process and is not easily broken, which can greatly reduce processing costs and is beneficial to energy saving;

3) Good electrical and thermal conductivity, and good ductility.

aluminum collapsible tube is a good conductor of heat, and its thermal conductivity is three times greater than that of iron; and its electrical conductivity is second only to silver and copper. When the paste is hot filled, it is more conducive to the rapid cooling and heat dissipation of the paste, which effectively guarantees the paste’s thermal conductivity. stability

4) Good shading and strong reflectivity.

The polished surface of aluminum collapsible tube has a reflectivity of more than 80% to white light. The higher the purity, the higher the reflectivity, especially for infrared, ultraviolet, heat radiation, etc. It has good reflectivity, and can be used for storage in various occasions, saving more Higher storage and circulation costs are suitable for long-term display on the counter, increasing the probability of product exposure;

5) High barrier performance.

Compared with other non-aluminum collapsible tube materials, aluminum collapsible tube has excellent moisture and gas barrier properties. Generally speaking, when the thickness of the aluminum collapsible tube foil is greater than 0.01mm, it has good moisture resistance; when the thickness is greater than 0.015mm, it has gas impermeability. The increase in thickness can effectively improve the barrier performance. The wall thickness of the aluminum collapsible tube tube of the ointment aluminum collapsible tube hose is greater than 0.09mm, which is much higher than the thickness of any aluminum collapsible tube foil, so its barrier performance is certain;

6) Non-magnetic, no sparks due to impact.

This feature brings great guarantee for safe production management, and also brings high security to market circulation.

7) Beautiful aluminum collapsible tube and its alloys have a silver-white luster due to their strong reflective properties. After processing, they can achieve high smoothness and brightness. aluminum collapsible tube is good for printing and spraying and can make the surface bright and colorful.

Four, summary

1) The corrosion resistance and sealing characteristics of the medicinal aluminum collapsible tube hose correspond to the sealing performance and safety performance of the ointment packaging material. The aluminum collapsible tube surface can form aluminum collapsible tube oxide to resist corrosion, and the tail coating is sealed, which has a protective effect on the internal ointment. The aluminum collapsible tube is soft and safe. Sealed to prevent corrosion.

2) aluminum collapsible tube has low density, good processing performance, strong plasticity, low processing cost, which is suitable for economic function and processing performance of ointment packaging. aluminum collapsible tube is convenient to obtain, low price, simple manufacturing and processing technology, not easy to break, and cost saving. Different from aluminum collapsible tube-plastic tubes, plastic hoses, and pharmaceutical aluminum collapsible tube hoses, they are easy to recycle after use, which is safe and environmentally friendly

3) The high barrier properties of aluminum collapsible tube materials must meet the barrier properties of ointment packaging. aluminum collapsible tube has excellent moisture and gas barrier properties.

4) aluminum collapsible tube, non-magnetic, no sparks due to impact, aluminum collapsible tube is soft, safe and non-toxic, processing has no solvent residue, and is easy to recycle after use, which fully meets the safety performance of ointment packaging.

5) aluminum collapsible tube is more used as aerospace material, and its physical and mechanical properties are very good. The aluminum collapsible tube hose has very good squeezability and no rebound air enters. It is the best choice for ointment packaging.

6) The aluminum collapsible tube hose fully meets the performance characteristics of ointment packaging and is the choice for ointment packaging.
